EVELYN HUTCHINSON AWARD</b></span></p><p><b>EBK</b>: Together with my lab group, we quantify small polar metabolites in seawater that may be used in exchange reactions between microbes. Although some of our measurements target molecules that have been observed by others (like amino acids), many of our measurements are the first of their kind in seawater and thus bring new insights into the molecules that could be important currencies in marine microbial consortia. My favorite molecule in this context is pantothenic acid (vitamin B<sub>5</sub>). Pantothenic acid is a precursor to coenzyme A (CoA), a critical intermediate in the carbon cycle, and its intracellular concentrations can regulate carbon cycling in many cells. Because almost all organisms can produce pantothenic acid due to its role in the foundational metabolism of the cell, vitamin B<sub>5</sub> was not considered to be an important molecule for exchange among microbes and thus was rarely measured in seawater. Over the past four years, we measured monthly or bi-monthly pantothenic acid concentrations at the Bermuda Atlantic Time-series Study (BATS) site in the North Atlantic Ocean. The depth profile of pantothenic acid is remarkably stable over time, with elevated concentrations in the upper 100 m, and decreasing into the mesopelagic zone. With newer methods, we see some structure in these profiles, indicating that pantothenic acid concentrations are responding to different consortia with depth. I am interested in determining the controlling factors on pantothenic concentrations with the goal of understanding its role in consortia and its turnover time in the surface ocean.</p><p><b>EBK</b>: C-CoMP has a multifaceted mission: (1) to explore the intricacies of the microbe-metabolite network in the ocean sufficiently to understand its role in regulating carbon cycling and its sensitivities to a changing climate; (2) to expand ocean literacy at all education levels; and (3) to broaden the diversity of ocean scientists. In our science research, we use a combination of laboratory, field, and computational studies to explore ocean microbes and their chemical impact at high resolution and efficiency in the current and future environment. Our education researchers study how to bring more ocean science content to K–12 science curricula and how to support emerging research careers within undergraduate, graduate, and postdoctoral research populations. In addition, we develop and support course-based undergraduate research experiences (CUREs) that bring our ocean science research to undergraduate classrooms. Finally, C-CoMP supports two year fellowships for postbaccalaureate students and for postdoctoral scholars. We use open-science approaches and best practices in team science to build a culture of equity and inclusion in C-CoMP.</p><p>If we are successful in our renewal proposal, ten years of C-CoMP will build a community of integrated scholars and educators dedicated to understanding important ocean processes at a critical time for our planet. I hope that this community will be ready to tackle important questions of carbon cycling, in particular, the rates of change with the microbe-metabolite network that impact carbon flux in the surface ocean. I hope that we will provide a pathway for K–12 curricula to incorporate ocean science literacy to educate the next generation about the importance of the ocean in our planet's health. Lastly, I hope that the next generation of ocean scientists will include talent from all backgrounds and lived experiences, ready to bring their creativity and ingenuity to mitigating the impacts of climate change on the ocean's ecosystems.</p><p><b>EBK</b>: I would like to understand the rates of turnover of metabolites within the labile DOM pool in different strata of the ocean. These rates are critically important to understanding the dynamics of labile DOM and, by extension, to the sensitivity of the carbon turnover every year in the surface ocean. Adding these rates (and related parameters) to biogeochemical models will rapidly expand our ability to probe the intricacies of the ocean microbiome. My lab has developed two new methods for measuring dissolved metabolites; these methods use sufficiently small sample volumes such that they are suitable for rate studies that disentangle the sources and sinks of metabolites. I would like to train the next generation of DOM scientists to use these methods to answer our community's emerging questions at the intersection of marine microbial ecology and biogeochemistry. I cannot imagine a better legacy than empowering marine scientists across the world to understand our oceans better.</p><p><span><b>RAYMOND L. LINDEMAN AWARD</b></span></p><p><b>RL</b>: It is hard to think of a single surprising result as there were many. In studies where you have multiple different types of analysis covering a wide array of biological and chemical properties, especially when they are so widespread in time, most results come sequentially and not all at once. For example, I measured the first DOC (dissolved organic carbon) and FDOM (fluorescent dissolved organic matter) concentrations rapidly when I came back from the Labrador Sea, but I had to wait a few months to analyze Fourier-transform ion cyclotron resonance mass spectrometry samples and several more months for 16S. By the time I got the 16S data, the core story about DOM transformation was shaping and this new analysis, which brought a different perspective than the chemical data, fit nicely with the patterns that we observed. I think this is what surprised me the most, every time I included a new analysis, it made sense with the existing story without modifying it too much. About two years after starting the experiment when I measured the last DOC samples, they all had the same values which was surprising to me, but still made sense. Of course, finding the right approach and analysis to use took time and efforts at every step of the process and I needed to be creative on how to illustrate the results to make a cohesive story. But overall, there were no conflicting results even with such a diverse array of analyses.</p><p><b>RL</b>: I think the microbial carbon pump (MCP) has a lot of research opportunities as there are so many unknowns. When we read the literature on the subject, the MCP is depicted as an important pathway of carbon sequestration that has, over a long period of time, built up the immense reservoir of DOC in the oceans. However, we also need to remember that carbon sequestrated this way by microbes is the exception, not the norm: most of the organic molecules are incorporated into biomass or mineralized. Finding under which specific circumstances refractory dissolved organic carbon (RDOC) is produced will allow us to calculate the rates of sequestration and assess the potential magnitude of this process in response to climate change. This field of research is also heavily method-driven, and I think we (the scientific community) will need to take a step back to get a broader picture before moving forward. On a final thought, my study looked at the question using multiple angles taken from biogeochemistry, microbial ecology, and ocean physics. I believe that future breakthroughs will also require collaboration among different fields of research to have a more holistic understanding of the MCP.</p><p><b>RL</b>: Publishing is a hard process and there is no shortcut. First, you need to hone your writing skills, especially if English is not your first language. The way you transmit your ideas in an article is as important as the ideas themselves: there are thousands of papers published in aquatic sciences each year and you need your research to stand out. There are numerous excellent books on how to write, how to write science, on writing habits, and so on. Find one that you enjoy reading and re-reading, this will make your own writing much easier. Learn to enjoy writing, it will become less of a burden but something you are excited about. All the efforts that you put in learning how to be a better writer will pay off multiple times over your career, whether you stay in academia or not.</p><p>Once the paper is written and all co-authors are happy with it, there is still the peer-review process. And it is hard. More often than not, reviewers will tear down the article and find everything that does not work, hopefully to make your science and/or storytelling better. When you first open the comments and read through them, you will likely get irritated, or sad, or any negative emotion really. That is normal. Take a deep breath, finish reading and close your document for at least twenty-four to forty-eight hours; there is nothing good that will come out of this in this state of mind. When that primal response is gone, open it again and start editing your manuscript. My experience is that I tend to agree with reviewers when they say something is not clear. If you learn to appreciate writing, editing your manuscript to incorporate reviewers' comments will be a lot easier. And then repeat for the number of reviewing rounds that is needed. My MCP paper got two desk rejections, and three split decisions before being accepted. Do not get discouraged with a negative review and use this opportunity to make your work better.</p><p><span><b>ALFRED C. REDFIELD LIFETIME ACHIEVEMENT AWARD</b></span></p><p><b>JS</b>: If I look back at my career and try to identify my biggest achievement, the answer is simple: it is the over 100 graduates (and an even larger number of undergraduates) that have passed through our lab and gone on to develop remarkable careers mainly in academia, but also in key government, NGO, or consultancy positions. When getting an award, I sometimes feel (to use a Canadian analogy) like the coach of an NHL hockey team that wins the Stanley Cup, but only I come onto the ice to hold the trophy! The contributions of my students and other collaborators have been remarkable. If I deserve any award, it should be for attracting highly dedicated and hard-working people, who enjoy doing important science and are a pleasure to be with.</p><p>When it comes to career turning points, and again this was very much a team effort, it was when I was still in my 20s, and acid rain was the major environmental issue in many parts of the world. Until then, paleolimnology was very much seen as an esoteric field, accused by some to be little more than “story telling.” Critical questions in the 1980s were: Have lakes acidified? If so, when and by how much? And who was to blame? A highly polarized debate was underway. Several of us realized that these questions could be answered from the sedimentary record if we could develop ways to reconstruct pH and associated changes over decades and centuries. This was a hectic time when policymakers wanted results and wanted them fast, and so highly reliable methods had to be quickly developed and applied. It helped that this issue also attracted diverse scientists, perhaps most notably those with highly developed numerical skills who would work with us to develop transfer functions and other multi-proxy approaches. Paleolimnologists showed that our techniques were robust and reproducible and that we could answer key policy questions.</p><p>This time was also a turning point for me as I began working frequently with the media, being interviewed on TV, radio, and newspapers (we did not have online media yet!) about our research and what it meant. I quickly realized that if there was an information vacuum, it would quickly be filled by opinions from vested interest groups. Scientists had to counter wishful thinking with evidence. It was a “baptism of fire” for me at this time. Things were different then in universities, and you often needed a thick skin—well of course there were serious attacks from the acid-producing industries (and their proxies), but also to some extent from other academics. I would hear, often second hand, comments like “Smol never saw a microphone he didn't like.” My view then is the same as it is now—the public, by-and-large, pay for the research we do, and they have a right to know what we found. If we do not transfer that knowledge and fill the information void with accessible language, then it will be filled by others.</p><p><b>JS</b>: This project (Smol <span>2023</span>) started with winning the <i>International Ecology Institute Prize</i> (https://www.int-res.com/ecology-institute/eci-prize), and one aspect of the award was to write a book (on any topic) in their <i>Excellence in Ecology</i> series (https://www.int-res.com/book-series/excellence-in-ecology-books/ee30/). I was always interested in the Arctic as one of the last largely unexplored areas on the planet, and last year marked my fortieth anniversary of Arctic research. Given the paucity of direct limnological observations, and given the sensitivity of polar regions, it was an ideal region to apply paleolimnological approaches. In this thirteen chapter book, which is part memoir and part textbook, I recounted the many ways we used history to address key environmental issues. An overriding theme is the critical role that accelerated climate change plays as a “threat multiplier.” Highlighted research includes collaborations with Indigenous knowledge holders and archeologists, tracking past ocean flooding events, the repercussions of permafrost thaw, the effects of pollutants from both local and distant sources, as well as tracking long-term changes in salmon and seabird populations. I emphasize the importance of using diverse sources of information, the role that personal relationships can play in successful collaborative programs (i.e., work well with colleagues and they will work well with you), and issues linked to environmental justice for Northern peoples.</p><p><b>JS</b>: I was asked to be the founding editor of the <i>Journal of Paleolimnology</i> when I was ~ thirty years old, a position I held for twenty years, and then became Editor of <i>Environmental Reviews</i>. Over those thirty-five plus years I learned that reviews are at times “opinions” and are not necessarily “facts,” and that editors, as gatekeepers, must be thorough and vigilant in weighing the evidence. You do not become an editor hoping to win popularity contests. Authors, reviewers, and editors are human, and often have strong opinions on what is right. The peer-review process, with all its frustrations, is not perfect, but it is the best system available.</p><p>I have often found that ECRs make excellent referees—they often know the recent literature well and have a keen interest in moving science forward. Yes, we are all busy, and yes, it is easy to press “decline,” but it is our collective responsibility to contribute to the peer-review process. Mentors can play a key role here as well. If senior scientists cannot do a review, they can suggest ECRs (whom the editor may not yet know) as alternate referees. ECRs can also take a proactive approach and send their CVs to editors, noting they are available to review in specific areas. If you are asked to do a review, accept the role (if appropriate) and appreciate that your main job is to point out errors in approaches or conclusions, with an overall goal of improving the paper. Remember, there are constructive ways to criticize. Stated more plainly, being anonymous is no excuse for being a jerk!</p><p><span><b>RUTH PATRICK AWARD</b></span></p><p><b>BS</b>: Early in graduate school at the University of Pennsylvania, Dr. Ruth Patrick handed me a small collection of recently published articles. They described how unnatural thermal modification of river reaches downstream of large dams (cold water) and power plants (hot water) was extinguishing the resident aquatic fauna and flora, although lethal minimum or maximum temperatures did not appear to be involved. Ruth said “read the papers and think about this huge environmental problem” and “a reasonable hypothesis for this matter will be a meaningful contribution to limnology.” At the time, Ruth was my thesis advisor so I took this challenge very seriously. I discussed several ideas with Dr. Robin Vannote who was also on my advisory committee and Director of the Stroud Water Research Center at the time. He thought my initial ideas were “too obvious” and “unlikely to be productive” and so challenged me to think more broadly and deeply about the problem. My thinking and emphasis at the time was on aquatic insects, especially mayflies (order Ephemeroptera) because they were being devastated by the thermal pollution. In addition, mayflies were well suited for laboratory work because some species had short life cycles, all were short lived as adults, and females metamorphosed with their full complement of eggs (hence fecundity reflects larval rearing conditions). So, I proposed field and laboratory studies involving the interaction of temperature with larval bioenergetics, developmental dynamics, and the ecological/biogeographical aspects of life history phenomena. After a series of experiments under different temperature regimes (fluctuating and constant; published in <i>L&amp;O</i> and <i>Ecology</i>) and considering the geographic distribution of mayfly species, we (Vannote and me) published the “Thermal Equilibrium Hypothesis” in <i>Science</i> (Sweeney and Vannote <span>1978</span>) and <i>The American Naturalist</i> (Vannote and Sweeney <span>1980</span>). The hypothesis proposed, among other things, that extreme temperature patterns caused by humans or by extreme southern or northern locations disrupted a species' metabolic, growth, and developmental dynamics, and hence life history characteristics such that individual fecundity was compromised leading to gradual population extinction. This success inspired me to consider other questions/challenges related to aquatic insects and stream and river ecosystems and seek fundamental solutions with good science. I believe that our field can and should continue to evolve in this direction i.e., seeking answers and direction grounded in the best science and using it as the basis for sound environmental policy.</p><p><b>BS</b>: My best advice is to be eclectic i.e., generate your ideas and approaches to understanding, evaluating, and solving scientific/environmental problems from a broad and diverse range of sources. In looking back, I benefitted from reading a broad spectrum of articles in aquatic journals associated with societies like ASLO, Society for Freshwater Science, the Ecological Society of America, the Society for Evolution. However, with the encouragement of Robin Vannote in graduate school, I also developed a lifelong habit of browsing through all the articles in the weekly issues of the journal <i>Science</i> while always looking at each abstract, article, or news item for something of value or relevance to aquatic science. This was mentally stimulating and rewarding in terms of research approaches and ideas and encouraged me to incorporate the latest technology into my experimentation. Also, I think it helped me pose questions regarding aquatic ecosystems that were forward thinking and often out of the norm.</p><p><b>BS</b>: It is hard for me to separate lessons learned in graduate school from Drs. Ruth Patrick and Robin Vannote. Both always emphasized the need to understand how a stream or river worked naturally in order to: (1) know whether it was disturbed or impacted by something; (2) the degree to which it was impacted; and (3) how to mitigate the impact. In other words, basic research on natural systems was key to evaluating and restoring disturbed/polluted systems. Robin was more interested in natural ecosystems. Ruth always stressed that you could learn a lot from carefully studying both pristine and polluted aquatic ecosystems.</p><p>Ruth kept you on your toes. There was no passing by her without her asking you questions like…. What new thing did you learn today? What exciting paper did you read in the last two days and please give me a three-sentence summary? If she assigned five technical papers to read before the next class, you had better have read and thought about them because she was going to call on someone (maybe you) to stand up and provide a summary and take away message for all five. In her lectures, Ruth emphasized the resiliency of aquatic ecosystems, with each species being quite resilient unto itself and collectively contributing to the resiliency of the ecosystem. She cautioned, however, that the magnitude and frequency of human impacts can overwhelm this resiliency. She often used field trips to drive home her lecture points. For example, one Sunday morning she had us (graduate students) collect from a stream in Pennsylvania that was impacted by acid mine pollution and then we spent the afternoon collecting from a natural stream in the New Jersey pine barrens. The pH of both streams was highly acidic (~ 3). We collected very few individuals or species of algae, macroinvertebrates, and fish from the acid mine stream but many individuals and species from the pine barren stream. Ruth collected alongside of us in her hip boots despite being around sixty-five years old but spoke little all day. At days end, we reported out our findings. Without discussion she then said: “Ladies and Gentlemen, you now have demonstrated for yourselves that aquatic species and ecosystems can adapt to stressful situations (like low pH) but if, only if, they are given enough time… class dismissed.” Other take aways for me from Ruth and Robin were: (1) aquatic systems are resilient and so polluted ones will recover with restoration of a more natural setting; (2) diversity within and among trophic levels is the key to ecosystem stability and functionality; (3) each species is important; (4) science is fast paced and one needs to work 24/7 at it to excel; (5) set the bar high and then go for it; and (6) do not give up… just think about it harder.</p><p><span><b>JOHN H. MARTIN AWARD</b></span></p><p><b>PH</b>: Work around the idea of lake metabolism has changed substantially in the past twenty years. Initially, the community focused on deployment of the kinds of sensors needed to estimate metabolism, especially dissolved oxygen and temperature, as well as meteorological data in some cases. Because of the costs and the effort, people mostly measured these variables at one location near the lake surface and during typical field seasons (summer). Questions around spatial heterogeneity arose, and a bunch of work emerged on littoral vs. pelagic metabolism and metabolism at different depths in the water column. In lakes with substantial littoral zones, spatial heterogeneity can matter a lot. In stratified lakes, there are big differences between epilimnetic and hypolimnetic metabolism. Similarly for time, there were important questions about seasonal to annual scales of metabolism that people began addressing as sensor deployments began spanning years. It came as no surprise that in lakes with strong seasonal patterns, lake metabolism varied with seasonal temperature, stratification patterns, and available light and nutrients. Analytical models evolved at the same time to include variations on process-based models, both in their complicatedness and how they were fit to the observational data. With multi-year data and models that accommodated seasonality, people began asking questions about whole lake carbon budgets and the roles lakes play in the landscape-scale carbon cycling. Recently, there has been an emphasis on lake metabolism as a framework for water quality, because the modeling approach lends itself to estimating dynamics of oxygen, particulate organic carbon (index of algal biomass), and water clarity. These three variables are indicators of lake trophic state and can determine, for example, oxythermal habitat.</p><p><b>PH</b>: To me, the most rewarding aspect of this highly cited paper is the discussions and collaborations it has catalyzed. As a reader, some of my favorite papers are relatively simple, with a clear question and results that speak clearly to the question. I feel like our paper meets those criteria. Our paper also came out about the time when sensors were becoming affordable for limnologists. I do not think we anticipated how a simple science question, coupled with new and accessible technologies, would resonate so well with our community.</p><p><b>PH</b>: The Global Lake Ecological Observatory Network (GLEON) started as a collaboration between two limnologists, David Hamilton and Tim Kratz, and two computer scientists, Peter Arzberger and Fang-Pang Lin. The initial vision was to build a global network of lake observatories that would provide data across new time scales over a broad gradient of lake ecosystems. Lake metabolism was an early use-case. As GLEON rapidly grew, lake metabolism became the topic of one of the working groups, because it is easy to understand, is relevant to many questions about lakes and reservoirs, makes great use of commonly measured limnological variables, and can be modeled in different ways towards different problems. Lake metabolism also helped catalyze common software code development. There are a number of software tools from GLEON that are still in use today, including LakeMetabolizer. Sharing ideas, skills, and resources is baked into the GLEON collaborative framework, and lake metabolism is an idea and approach that fits nicely therein. For NTL-LTER, there is more to say than I have space to say it, but the theme is that NTL-LTER enables innovative research of all kinds, including lake metabolism. Many lake metabolism papers are about the NTL-LTER study lakes or include them in more extensive analyses because of the comprehensive and long-term data, which are openly available. However, it always comes back to the community. Colleagues at NTL-LTER are a constant source of ideas, productivity, and support, which has led to many creative papers on metabolism. Most recent work has included long-term phenology of lake metabolism, projections of recovery from eutrophication based on a metabolism framework, and use of lake metabolism to train machine learning models.</p><p><span><b>RAMÓN MARGALEF AWARD FOR EXCELLENCE IN EDUCATION</b></span></p><p><b>RC</b>: I come from a family of educators. I joined the Environmental Sciences Program at University of Massachusetts Boston in 1992. This was a graduate program, but I told the dean that I wanted to teach undergraduate students. Thirty-two years later, I teach the largest class on campus, Introduction to Environmental Science, at five hundred and fifty students, and the program has become a fully independent undergraduate and graduate School for the Environment.</p><p>My first exploration of outreach was a large ocean education fair where I showed how lasers could be used to detect chlorophyll and colored dissolved organic matter in seawater. It was a big hit, and I realized outreach was something at which I could be good, and that could make an impact on public understanding of ocean science.</p><p>My first big project was the Watershed Integrated Sciences Partnership (WISP), where we worked with three school districts to integrate resources and activities around the Neponset Watershed in the classroom (https://www.wisp.umb.edu). WISP was supported by the NSF GK-12 program, where graduate science students were placed in middle school classrooms throughout the year. Through this project, I worked closely with Boston Public Schools, middle school teachers, and inquiry-based science curriculum, and developed professional development for scientists interested in teaching, science communication, and outreach.</p><p>Then there was Centers for Ocean Science Education Excellence (COSEE): COSEE New England and COSEE OCEAN. Through this work and my service on the ASLO Education and Engagement Committee, I was able to collaborate regionally and nationally with ocean education experts, international organizations, and dedicated individuals from the science and informal and formal education communities. We developed the Ocean Literacy Principles, integrated ocean curriculum into national and local standards, created new positions in research organizations for education and outreach coordinators, and distributed over 20,000 copies of the Best of COSEE Hands-On Activities (http://www.cosee.net/best_activities). Two organizations have resulted from this work: COSEE China and the New England Ocean Science Collaborative (www.neosec.org).</p><p>The Boston Science Partnership was an NSF Math Science Partnership where we worked closely with Boston Public Schools to offer professional development for over six hundred science teachers that increased the standardized test scores of students who were taught by the teachers who participated in our programs. Cool Science, an NSF Advancing Informal Science Learning program, blends art and science through youth developing posters on climate change and educating adults by placing winning artwork on public buses in Massachusetts, Kansas, and Missouri. Educational innovations were supported from both the science and education divisions within NSF, NASA, ONR, and SeaGrant, and have led to successful integrative projects from Foundations such as the Stone Foundation and Waverly Street Foundation.</p><p>These large educational grants helped fund my graduate students and my lab, helped me get promoted to Full Professor, and allowed me to become a better educator and scientist at the professor, dean, and community partner levels (Chen <span>2008</span>).</p><p>I have been invited to serve on the Boards of the New England Aquarium, the Alliance for Business Leadership, Climate Beacon, and ASLO for my work bridging ocean science and education. Many of my graduate students have gone on to impactful careers as scientists with strong communication and teaching skills and educators with strong scientific content knowledge and understanding, and in new transdisciplinary jobs that we did not know existed.</p><p>My work crossing, integrating, and blending scientific research with formal and informal STEM and art education across the K through Gray spectrum continues….</p><p><b>RC</b>: As part of the Partners Aligned To Heighten broad participation in STEM program (PATHS; www.pathspartners.org), Black, Indigenous, and People of Color (BIPOC) participants work closely with the Digital Storytelling in Asian American Studies Team supervised by Dr. Shirley Tang at University of Massachusetts Boston. We lift up BIPOC voices, foster visions for change, and promote BIPOC leadership within STEM pathways as we create video products with participants through a labor-intensive co-production process.</p><p>At the first cohort's premier event in June 2022 at the Museum of Science in Boston, I had the privilege to view seven video stories with storytellers, their families and friends, and a broad audience from across Boston. Without a dry eye in the crowd, I stood up and made the comment that I now question every interaction I have ever had with any of my students over my last thirty-five years, as one micro-affirmation vs. one micro-aggression could change the career pathway of any of these gifted individuals: a smile in the hallway, my hurrying off after my big class, my providing an extension for a student who may be working sixty hours per week without enough food to eat. I think about this moment often, and try to do better… to get to know my students, to not make assumptions about them, to celebrate their diverse backgrounds, assets, and perspectives. Excerpts from these video stories can be viewed at: https://www.pathspartners.org/year1stories.</p><p><b>RC</b>:</p><p><i>Listen</i>. When you are working with students, young scientists, or community scientists, you should get to know them as individuals, what interests them, what drives them. In this way, you can modify appropriately the way you convey your scientific knowledge, interests, and perspectives. By carefully respecting and understanding the specific audience that you might be working with, they will become more engaged, see your science as more relevant, and will sometimes be inspired to get involved.</p><p><i>Practice</i>. Being able to explain your research to diverse audiences is a skill that can be developed. Just as with lab skills and experimentation, practice makes better. The more you practice explaining your research to non-scientists, telling stories about ocean science, and trying new analogies that can help explain complex concepts, the better you can become at teaching, engaging, and supporting young scientists.</p><p><i>Assess and improve</i>. By viewing your classroom or science fair as a laboratory, you can continually improve your education and outreach skills. Scientists critically evaluation and examine their methods and data to come to their conclusions and move their science forward; educators that use constant assessment and evaluation can also develop sharable best practices and programs and move their education and outreach forward.</p><p><span><b>YENTSCH-SCHINDLER EARLY CAREER AWARD</b></span></p><p><b>HD</b>: Throughout the time I have worked on the issue, it is been rewarding to see the topic of freshwater salinization gain notoriety, especially in the region of North America I live in. Scientifically I am most proud of some of the amazing research carried out by my current and former lab members. Robert Ladwig led a paper in <i>L&amp;O Letters</i> examining the impact of salinization on lake stratification and spring mixing. In my mind it is a perfect example of blending empirical observations, analytical approaches, and detailed simulations to tackle a problem (Ladwig et al. <span>2023</span>). Linnea Rock carried out an intensive two-year sampling campaign (during covid) to show that lakes fundamentally alter the salinity regimes of downstream rivers (Rock and Dugan <span>2023</span>). Lindsay Platt is currently wrapping up a project leveraging USGS stream data. Her public workflow is a masterpiece of reproducible research that can be leveraged by others to tackle big water questions.</p><p><b>HD</b>: I certainly try to. I have learned over the years that open science has many benefits. (1) It enhances the quality of science. Transparency allows for increased scrutiny of research findings, by both you and scientific reviewers, which leads to more robust research papers. (2) It saves time, especially for the future-you. Having clean data and code that can be reused and quickly understood streamlines the scientific process. Given the complexity of science these days, independently recreating every step of a project is too time-consuming. Yes, it is critical to know the fundamentals (do not skip that statistics class), but be efficient where you can be. (3) Open science promotes collaboration, especially across disciplines. Some of the coolest science I have seen is people who adapted methods from other disciplines. This is incredibly hard to do without openly sharing resources, ideas, and methods. (4) Not a benefit, just the bottom line. If your data was publicly funded, it should be publicly accessible.</p><p>Looking ahead, open science will continue to grow, especially with the upcoming cohort of scientists trained in the principles of open science. Still, it is not easy. It takes time, perseverance, and commitment, and none of us do it perfectly.

EVELYN HUTCHINSON AWARD</b></span></p><p><b>EBK</b>: Together with my lab group, we quantify small polar metabolites in seawater that may be used in exchange reactions between microbes. Although some of our measurements target molecules that have been observed by others (like amino acids), many of our measurements are the first of their kind in seawater and thus bring new insights into the molecules that could be important currencies in marine microbial consortia. My favorite molecule in this context is pantothenic acid (vitamin B<sub>5</sub>). Pantothenic acid is a precursor to coenzyme A (CoA), a critical intermediate in the carbon cycle, and its intracellular concentrations can regulate carbon cycling in many cells. Because almost all organisms can produce pantothenic acid due to its role in the foundational metabolism of the cell, vitamin B<sub>5</sub> was not considered to be an important molecule for exchange among microbes and thus was rarely measured in seawater. Over the past four years, we measured monthly or bi-monthly pantothenic acid concentrations at the Bermuda Atlantic Time-series Study (BATS) site in the North Atlantic Ocean. The depth profile of pantothenic acid is remarkably stable over time, with elevated concentrations in the upper 100 m, and decreasing into the mesopelagic zone. With newer methods, we see some structure in these profiles, indicating that pantothenic acid concentrations are responding to different consortia with depth. I am interested in determining the controlling factors on pantothenic concentrations with the goal of understanding its role in consortia and its turnover time in the surface ocean.</p><p><b>EBK</b>: C-CoMP has a multifaceted mission: (1) to explore the intricacies of the microbe-metabolite network in the ocean sufficiently to understand its role in regulating carbon cycling and its sensitivities to a changing climate; (2) to expand ocean literacy at all education levels; and (3) to broaden the diversity of ocean scientists. In our science research, we use a combination of laboratory, field, and computational studies to explore ocean microbes and their chemical impact at high resolution and efficiency in the current and future environment. Our education researchers study how to bring more ocean science content to K–12 science curricula and how to support emerging research careers within undergraduate, graduate, and postdoctoral research populations. In addition, we develop and support course-based undergraduate research experiences (CUREs) that bring our ocean science research to undergraduate classrooms. Finally, C-CoMP supports two year fellowships for postbaccalaureate students and for postdoctoral scholars. We use open-science approaches and best practices in team science to build a culture of equity and inclusion in C-CoMP.</p><p>If we are successful in our renewal proposal, ten years of C-CoMP will build a community of integrated scholars and educators dedicated to understanding important ocean processes at a critical time for our planet. I hope that this community will be ready to tackle important questions of carbon cycling, in particular, the rates of change with the microbe-metabolite network that impact carbon flux in the surface ocean. I hope that we will provide a pathway for K–12 curricula to incorporate ocean science literacy to educate the next generation about the importance of the ocean in our planet's health. Lastly, I hope that the next generation of ocean scientists will include talent from all backgrounds and lived experiences, ready to bring their creativity and ingenuity to mitigating the impacts of climate change on the ocean's ecosystems.</p><p><b>EBK</b>: I would like to understand the rates of turnover of metabolites within the labile DOM pool in different strata of the ocean. These rates are critically important to understanding the dynamics of labile DOM and, by extension, to the sensitivity of the carbon turnover every year in the surface ocean. Adding these rates (and related parameters) to biogeochemical models will rapidly expand our ability to probe the intricacies of the ocean microbiome. My lab has developed two new methods for measuring dissolved metabolites; these methods use sufficiently small sample volumes such that they are suitable for rate studies that disentangle the sources and sinks of metabolites. I would like to train the next generation of DOM scientists to use these methods to answer our community's emerging questions at the intersection of marine microbial ecology and biogeochemistry. I cannot imagine a better legacy than empowering marine scientists across the world to understand our oceans better.</p><p><span><b>RAYMOND L. LINDEMAN AWARD</b></span></p><p><b>RL</b>: It is hard to think of a single surprising result as there were many. In studies where you have multiple different types of analysis covering a wide array of biological and chemical properties, especially when they are so widespread in time, most results come sequentially and not all at once. For example, I measured the first DOC (dissolved organic carbon) and FDOM (fluorescent dissolved organic matter) concentrations rapidly when I came back from the Labrador Sea, but I had to wait a few months to analyze Fourier-transform ion cyclotron resonance mass spectrometry samples and several more months for 16S. By the time I got the 16S data, the core story about DOM transformation was shaping and this new analysis, which brought a different perspective than the chemical data, fit nicely with the patterns that we observed. I think this is what surprised me the most, every time I included a new analysis, it made sense with the existing story without modifying it too much. About two years after starting the experiment when I measured the last DOC samples, they all had the same values which was surprising to me, but still made sense. Of course, finding the right approach and analysis to use took time and efforts at every step of the process and I needed to be creative on how to illustrate the results to make a cohesive story. But overall, there were no conflicting results even with such a diverse array of analyses.</p><p><b>RL</b>: I think the microbial carbon pump (MCP) has a lot of research opportunities as there are so many unknowns. When we read the literature on the subject, the MCP is depicted as an important pathway of carbon sequestration that has, over a long period of time, built up the immense reservoir of DOC in the oceans. However, we also need to remember that carbon sequestrated this way by microbes is the exception, not the norm: most of the organic molecules are incorporated into biomass or mineralized. Finding under which specific circumstances refractory dissolved organic carbon (RDOC) is produced will allow us to calculate the rates of sequestration and assess the potential magnitude of this process in response to climate change. This field of research is also heavily method-driven, and I think we (the scientific community) will need to take a step back to get a broader picture before moving forward. On a final thought, my study looked at the question using multiple angles taken from biogeochemistry, microbial ecology, and ocean physics. I believe that future breakthroughs will also require collaboration among different fields of research to have a more holistic understanding of the MCP.</p><p><b>RL</b>: Publishing is a hard process and there is no shortcut. First, you need to hone your writing skills, especially if English is not your first language. The way you transmit your ideas in an article is as important as the ideas themselves: there are thousands of papers published in aquatic sciences each year and you need your research to stand out. There are numerous excellent books on how to write, how to write science, on writing habits, and so on. Find one that you enjoy reading and re-reading, this will make your own writing much easier. Learn to enjoy writing, it will become less of a burden but something you are excited about. All the efforts that you put in learning how to be a better writer will pay off multiple times over your career, whether you stay in academia or not.</p><p>Once the paper is written and all co-authors are happy with it, there is still the peer-review process. And it is hard. More often than not, reviewers will tear down the article and find everything that does not work, hopefully to make your science and/or storytelling better. When you first open the comments and read through them, you will likely get irritated, or sad, or any negative emotion really. That is normal. Take a deep breath, finish reading and close your document for at least twenty-four to forty-eight hours; there is nothing good that will come out of this in this state of mind. When that primal response is gone, open it again and start editing your manuscript. My experience is that I tend to agree with reviewers when they say something is not clear. If you learn to appreciate writing, editing your manuscript to incorporate reviewers' comments will be a lot easier. And then repeat for the number of reviewing rounds that is needed. My MCP paper got two desk rejections, and three split decisions before being accepted. Do not get discouraged with a negative review and use this opportunity to make your work better.</p><p><span><b>ALFRED C. REDFIELD LIFETIME ACHIEVEMENT AWARD</b></span></p><p><b>JS</b>: If I look back at my career and try to identify my biggest achievement, the answer is simple: it is the over 100 graduates (and an even larger number of undergraduates) that have passed through our lab and gone on to develop remarkable careers mainly in academia, but also in key government, NGO, or consultancy positions. When getting an award, I sometimes feel (to use a Canadian analogy) like the coach of an NHL hockey team that wins the Stanley Cup, but only I come onto the ice to hold the trophy! The contributions of my students and other collaborators have been remarkable. If I deserve any award, it should be for attracting highly dedicated and hard-working people, who enjoy doing important science and are a pleasure to be with.</p><p>When it comes to career turning points, and again this was very much a team effort, it was when I was still in my 20s, and acid rain was the major environmental issue in many parts of the world. Until then, paleolimnology was very much seen as an esoteric field, accused by some to be little more than “story telling.” Critical questions in the 1980s were: Have lakes acidified? If so, when and by how much? And who was to blame? A highly polarized debate was underway. Several of us realized that these questions could be answered from the sedimentary record if we could develop ways to reconstruct pH and associated changes over decades and centuries. This was a hectic time when policymakers wanted results and wanted them fast, and so highly reliable methods had to be quickly developed and applied. It helped that this issue also attracted diverse scientists, perhaps most notably those with highly developed numerical skills who would work with us to develop transfer functions and other multi-proxy approaches. Paleolimnologists showed that our techniques were robust and reproducible and that we could answer key policy questions.</p><p>This time was also a turning point for me as I began working frequently with the media, being interviewed on TV, radio, and newspapers (we did not have online media yet!) about our research and what it meant. I quickly realized that if there was an information vacuum, it would quickly be filled by opinions from vested interest groups. Scientists had to counter wishful thinking with evidence. It was a “baptism of fire” for me at this time. Things were different then in universities, and you often needed a thick skin—well of course there were serious attacks from the acid-producing industries (and their proxies), but also to some extent from other academics. I would hear, often second hand, comments like “Smol never saw a microphone he didn't like.” My view then is the same as it is now—the public, by-and-large, pay for the research we do, and they have a right to know what we found. If we do not transfer that knowledge and fill the information void with accessible language, then it will be filled by others.</p><p><b>JS</b>: This project (Smol <span>2023</span>) started with winning the <i>International Ecology Institute Prize</i> (https://www.int-res.com/ecology-institute/eci-prize), and one aspect of the award was to write a book (on any topic) in their <i>Excellence in Ecology</i> series (https://www.int-res.com/book-series/excellence-in-ecology-books/ee30/). I was always interested in the Arctic as one of the last largely unexplored areas on the planet, and last year marked my fortieth anniversary of Arctic research. Given the paucity of direct limnological observations, and given the sensitivity of polar regions, it was an ideal region to apply paleolimnological approaches. In this thirteen chapter book, which is part memoir and part textbook, I recounted the many ways we used history to address key environmental issues. An overriding theme is the critical role that accelerated climate change plays as a “threat multiplier.” Highlighted research includes collaborations with Indigenous knowledge holders and archeologists, tracking past ocean flooding events, the repercussions of permafrost thaw, the effects of pollutants from both local and distant sources, as well as tracking long-term changes in salmon and seabird populations. I emphasize the importance of using diverse sources of information, the role that personal relationships can play in successful collaborative programs (i.e., work well with colleagues and they will work well with you), and issues linked to environmental justice for Northern peoples.</p><p><b>JS</b>: I was asked to be the founding editor of the <i>Journal of Paleolimnology</i> when I was ~ thirty years old, a position I held for twenty years, and then became Editor of <i>Environmental Reviews</i>. Over those thirty-five plus years I learned that reviews are at times “opinions” and are not necessarily “facts,” and that editors, as gatekeepers, must be thorough and vigilant in weighing the evidence. You do not become an editor hoping to win popularity contests. Authors, reviewers, and editors are human, and often have strong opinions on what is right. The peer-review process, with all its frustrations, is not perfect, but it is the best system available.</p><p>I have often found that ECRs make excellent referees—they often know the recent literature well and have a keen interest in moving science forward. Yes, we are all busy, and yes, it is easy to press “decline,” but it is our collective responsibility to contribute to the peer-review process. Mentors can play a key role here as well. If senior scientists cannot do a review, they can suggest ECRs (whom the editor may not yet know) as alternate referees. ECRs can also take a proactive approach and send their CVs to editors, noting they are available to review in specific areas. If you are asked to do a review, accept the role (if appropriate) and appreciate that your main job is to point out errors in approaches or conclusions, with an overall goal of improving the paper. Remember, there are constructive ways to criticize. Stated more plainly, being anonymous is no excuse for being a jerk!</p><p><span><b>RUTH PATRICK AWARD</b></span></p><p><b>BS</b>: Early in graduate school at the University of Pennsylvania, Dr. Ruth Patrick handed me a small collection of recently published articles. They described how unnatural thermal modification of river reaches downstream of large dams (cold water) and power plants (hot water) was extinguishing the resident aquatic fauna and flora, although lethal minimum or maximum temperatures did not appear to be involved. Ruth said “read the papers and think about this huge environmental problem” and “a reasonable hypothesis for this matter will be a meaningful contribution to limnology.” At the time, Ruth was my thesis advisor so I took this challenge very seriously. I discussed several ideas with Dr. Robin Vannote who was also on my advisory committee and Director of the Stroud Water Research Center at the time. He thought my initial ideas were “too obvious” and “unlikely to be productive” and so challenged me to think more broadly and deeply about the problem. My thinking and emphasis at the time was on aquatic insects, especially mayflies (order Ephemeroptera) because they were being devastated by the thermal pollution. In addition, mayflies were well suited for laboratory work because some species had short life cycles, all were short lived as adults, and females metamorphosed with their full complement of eggs (hence fecundity reflects larval rearing conditions). So, I proposed field and laboratory studies involving the interaction of temperature with larval bioenergetics, developmental dynamics, and the ecological/biogeographical aspects of life history phenomena. After a series of experiments under different temperature regimes (fluctuating and constant; published in <i>L&amp;O</i> and <i>Ecology</i>) and considering the geographic distribution of mayfly species, we (Vannote and me) published the “Thermal Equilibrium Hypothesis” in <i>Science</i> (Sweeney and Vannote <span>1978</span>) and <i>The American Naturalist</i> (Vannote and Sweeney <span>1980</span>). The hypothesis proposed, among other things, that extreme temperature patterns caused by humans or by extreme southern or northern locations disrupted a species' metabolic, growth, and developmental dynamics, and hence life history characteristics such that individual fecundity was compromised leading to gradual population extinction. This success inspired me to consider other questions/challenges related to aquatic insects and stream and river ecosystems and seek fundamental solutions with good science. I believe that our field can and should continue to evolve in this direction i.e., seeking answers and direction grounded in the best science and using it as the basis for sound environmental policy.</p><p><b>BS</b>: My best advice is to be eclectic i.e., generate your ideas and approaches to understanding, evaluating, and solving scientific/environmental problems from a broad and diverse range of sources. In looking back, I benefitted from reading a broad spectrum of articles in aquatic journals associated with societies like ASLO, Society for Freshwater Science, the Ecological Society of America, the Society for Evolution. However, with the encouragement of Robin Vannote in graduate school, I also developed a lifelong habit of browsing through all the articles in the weekly issues of the journal <i>Science</i> while always looking at each abstract, article, or news item for something of value or relevance to aquatic science. This was mentally stimulating and rewarding in terms of research approaches and ideas and encouraged me to incorporate the latest technology into my experimentation. Also, I think it helped me pose questions regarding aquatic ecosystems that were forward thinking and often out of the norm.</p><p><b>BS</b>: It is hard for me to separate lessons learned in graduate school from Drs. Ruth Patrick and Robin Vannote. Both always emphasized the need to understand how a stream or river worked naturally in order to: (1) know whether it was disturbed or impacted by something; (2) the degree to which it was impacted; and (3) how to mitigate the impact. In other words, basic research on natural systems was key to evaluating and restoring disturbed/polluted systems. Robin was more interested in natural ecosystems. Ruth always stressed that you could learn a lot from carefully studying both pristine and polluted aquatic ecosystems.</p><p>Ruth kept you on your toes. There was no passing by her without her asking you questions like…. What new thing did you learn today? What exciting paper did you read in the last two days and please give me a three-sentence summary? If she assigned five technical papers to read before the next class, you had better have read and thought about them because she was going to call on someone (maybe you) to stand up and provide a summary and take away message for all five. In her lectures, Ruth emphasized the resiliency of aquatic ecosystems, with each species being quite resilient unto itself and collectively contributing to the resiliency of the ecosystem. She cautioned, however, that the magnitude and frequency of human impacts can overwhelm this resiliency. She often used field trips to drive home her lecture points. For example, one Sunday morning she had us (graduate students) collect from a stream in Pennsylvania that was impacted by acid mine pollution and then we spent the afternoon collecting from a natural stream in the New Jersey pine barrens. The pH of both streams was highly acidic (~ 3). We collected very few individuals or species of algae, macroinvertebrates, and fish from the acid mine stream but many individuals and species from the pine barren stream. Ruth collected alongside of us in her hip boots despite being around sixty-five years old but spoke little all day. At days end, we reported out our findings. Without discussion she then said: “Ladies and Gentlemen, you now have demonstrated for yourselves that aquatic species and ecosystems can adapt to stressful situations (like low pH) but if, only if, they are given enough time… class dismissed.” Other take aways for me from Ruth and Robin were: (1) aquatic systems are resilient and so polluted ones will recover with restoration of a more natural setting; (2) diversity within and among trophic levels is the key to ecosystem stability and functionality; (3) each species is important; (4) science is fast paced and one needs to work 24/7 at it to excel; (5) set the bar high and then go for it; and (6) do not give up… just think about it harder.</p><p><span><b>JOHN H. MARTIN AWARD</b></span></p><p><b>PH</b>: Work around the idea of lake metabolism has changed substantially in the past twenty years. Initially, the community focused on deployment of the kinds of sensors needed to estimate metabolism, especially dissolved oxygen and temperature, as well as meteorological data in some cases. Because of the costs and the effort, people mostly measured these variables at one location near the lake surface and during typical field seasons (summer). Questions around spatial heterogeneity arose, and a bunch of work emerged on littoral vs. pelagic metabolism and metabolism at different depths in the water column. In lakes with substantial littoral zones, spatial heterogeneity can matter a lot. In stratified lakes, there are big differences between epilimnetic and hypolimnetic metabolism. Similarly for time, there were important questions about seasonal to annual scales of metabolism that people began addressing as sensor deployments began spanning years. It came as no surprise that in lakes with strong seasonal patterns, lake metabolism varied with seasonal temperature, stratification patterns, and available light and nutrients. Analytical models evolved at the same time to include variations on process-based models, both in their complicatedness and how they were fit to the observational data. With multi-year data and models that accommodated seasonality, people began asking questions about whole lake carbon budgets and the roles lakes play in the landscape-scale carbon cycling. Recently, there has been an emphasis on lake metabolism as a framework for water quality, because the modeling approach lends itself to estimating dynamics of oxygen, particulate organic carbon (index of algal biomass), and water clarity. These three variables are indicators of lake trophic state and can determine, for example, oxythermal habitat.</p><p><b>PH</b>: To me, the most rewarding aspect of this highly cited paper is the discussions and collaborations it has catalyzed. As a reader, some of my favorite papers are relatively simple, with a clear question and results that speak clearly to the question. I feel like our paper meets those criteria. Our paper also came out about the time when sensors were becoming affordable for limnologists. I do not think we anticipated how a simple science question, coupled with new and accessible technologies, would resonate so well with our community.</p><p><b>PH</b>: The Global Lake Ecological Observatory Network (GLEON) started as a collaboration between two limnologists, David Hamilton and Tim Kratz, and two computer scientists, Peter Arzberger and Fang-Pang Lin. The initial vision was to build a global network of lake observatories that would provide data across new time scales over a broad gradient of lake ecosystems. Lake metabolism was an early use-case. As GLEON rapidly grew, lake metabolism became the topic of one of the working groups, because it is easy to understand, is relevant to many questions about lakes and reservoirs, makes great use of commonly measured limnological variables, and can be modeled in different ways towards different problems. Lake metabolism also helped catalyze common software code development. There are a number of software tools from GLEON that are still in use today, including LakeMetabolizer. Sharing ideas, skills, and resources is baked into the GLEON collaborative framework, and lake metabolism is an idea and approach that fits nicely therein. For NTL-LTER, there is more to say than I have space to say it, but the theme is that NTL-LTER enables innovative research of all kinds, including lake metabolism. Many lake metabolism papers are about the NTL-LTER study lakes or include them in more extensive analyses because of the comprehensive and long-term data, which are openly available. However, it always comes back to the community. Colleagues at NTL-LTER are a constant source of ideas, productivity, and support, which has led to many creative papers on metabolism. Most recent work has included long-term phenology of lake metabolism, projections of recovery from eutrophication based on a metabolism framework, and use of lake metabolism to train machine learning models.</p><p><span><b>RAMÓN MARGALEF AWARD FOR EXCELLENCE IN EDUCATION</b></span></p><p><b>RC</b>: I come from a family of educators. I joined the Environmental Sciences Program at University of Massachusetts Boston in 1992. This was a graduate program, but I told the dean that I wanted to teach undergraduate students. Thirty-two years later, I teach the largest class on campus, Introduction to Environmental Science, at five hundred and fifty students, and the program has become a fully independent undergraduate and graduate School for the Environment.</p><p>My first exploration of outreach was a large ocean education fair where I showed how lasers could be used to detect chlorophyll and colored dissolved organic matter in seawater. It was a big hit, and I realized outreach was something at which I could be good, and that could make an impact on public understanding of ocean science.</p><p>My first big project was the Watershed Integrated Sciences Partnership (WISP), where we worked with three school districts to integrate resources and activities around the Neponset Watershed in the classroom (https://www.wisp.umb.edu). WISP was supported by the NSF GK-12 program, where graduate science students were placed in middle school classrooms throughout the year. Through this project, I worked closely with Boston Public Schools, middle school teachers, and inquiry-based science curriculum, and developed professional development for scientists interested in teaching, science communication, and outreach.</p><p>Then there was Centers for Ocean Science Education Excellence (COSEE): COSEE New England and COSEE OCEAN. Through this work and my service on the ASLO Education and Engagement Committee, I was able to collaborate regionally and nationally with ocean education experts, international organizations, and dedicated individuals from the science and informal and formal education communities. We developed the Ocean Literacy Principles, integrated ocean curriculum into national and local standards, created new positions in research organizations for education and outreach coordinators, and distributed over 20,000 copies of the Best of COSEE Hands-On Activities (http://www.cosee.net/best_activities). Two organizations have resulted from this work: COSEE China and the New England Ocean Science Collaborative (www.neosec.org).</p><p>The Boston Science Partnership was an NSF Math Science Partnership where we worked closely with Boston Public Schools to offer professional development for over six hundred science teachers that increased the standardized test scores of students who were taught by the teachers who participated in our programs. Cool Science, an NSF Advancing Informal Science Learning program, blends art and science through youth developing posters on climate change and educating adults by placing winning artwork on public buses in Massachusetts, Kansas, and Missouri. Educational innovations were supported from both the science and education divisions within NSF, NASA, ONR, and SeaGrant, and have led to successful integrative projects from Foundations such as the Stone Foundation and Waverly Street Foundation.</p><p>These large educational grants helped fund my graduate students and my lab, helped me get promoted to Full Professor, and allowed me to become a better educator and scientist at the professor, dean, and community partner levels (Chen <span>2008</span>).</p><p>I have been invited to serve on the Boards of the New England Aquarium, the Alliance for Business Leadership, Climate Beacon, and ASLO for my work bridging ocean science and education. Many of my graduate students have gone on to impactful careers as scientists with strong communication and teaching skills and educators with strong scientific content knowledge and understanding, and in new transdisciplinary jobs that we did not know existed.</p><p>My work crossing, integrating, and blending scientific research with formal and informal STEM and art education across the K through Gray spectrum continues….</p><p><b>RC</b>: As part of the Partners Aligned To Heighten broad participation in STEM program (PATHS; www.pathspartners.org), Black, Indigenous, and People of Color (BIPOC) participants work closely with the Digital Storytelling in Asian American Studies Team supervised by Dr. Shirley Tang at University of Massachusetts Boston. We lift up BIPOC voices, foster visions for change, and promote BIPOC leadership within STEM pathways as we create video products with participants through a labor-intensive co-production process.</p><p>At the first cohort's premier event in June 2022 at the Museum of Science in Boston, I had the privilege to view seven video stories with storytellers, their families and friends, and a broad audience from across Boston. Without a dry eye in the crowd, I stood up and made the comment that I now question every interaction I have ever had with any of my students over my last thirty-five years, as one micro-affirmation vs. one micro-aggression could change the career pathway of any of these gifted individuals: a smile in the hallway, my hurrying off after my big class, my providing an extension for a student who may be working sixty hours per week without enough food to eat. I think about this moment often, and try to do better… to get to know my students, to not make assumptions about them, to celebrate their diverse backgrounds, assets, and perspectives. Excerpts from these video stories can be viewed at: https://www.pathspartners.org/year1stories.</p><p><b>RC</b>:</p><p><i>Listen</i>. When you are working with students, young scientists, or community scientists, you should get to know them as individuals, what interests them, what drives them. In this way, you can modify appropriately the way you convey your scientific knowledge, interests, and perspectives. By carefully respecting and understanding the specific audience that you might be working with, they will become more engaged, see your science as more relevant, and will sometimes be inspired to get involved.</p><p><i>Practice</i>. Being able to explain your research to diverse audiences is a skill that can be developed. Just as with lab skills and experimentation, practice makes better. The more you practice explaining your research to non-scientists, telling stories about ocean science, and trying new analogies that can help explain complex concepts, the better you can become at teaching, engaging, and supporting young scientists.</p><p><i>Assess and improve</i>. By viewing your classroom or science fair as a laboratory, you can continually improve your education and outreach skills. Scientists critically evaluation and examine their methods and data to come to their conclusions and move their science forward; educators that use constant assessment and evaluation can also develop sharable best practices and programs and move their education and outreach forward.</p><p><span><b>YENTSCH-SCHINDLER EARLY CAREER AWARD</b></span></p><p><b>HD</b>: Throughout the time I have worked on the issue, it is been rewarding to see the topic of freshwater salinization gain notoriety, especially in the region of North America I live in. Scientifically I am most proud of some of the amazing research carried out by my current and former lab members. Robert Ladwig led a paper in <i>L&amp;O Letters</i> examining the impact of salinization on lake stratification and spring mixing. In my mind it is a perfect example of blending empirical observations, analytical approaches, and detailed simulations to tackle a problem (Ladwig et al. <span>2023</span>). Linnea Rock carried out an intensive two-year sampling campaign (during covid) to show that lakes fundamentally alter the salinity regimes of downstream rivers (Rock and Dugan <span>2023</span>). Lindsay Platt is currently wrapping up a project leveraging USGS stream data. Her public workflow is a masterpiece of reproducible research that can be leveraged by others to tackle big water questions.</p><p><b>HD</b>: I certainly try to. I have learned over the years that open science has many benefits. (1) It enhances the quality of science. Transparency allows for increased scrutiny of research findings, by both you and scientific reviewers, which leads to more robust research papers. (2) It saves time, especially for the future-you. Having clean data and code that can be reused and quickly understood streamlines the scientific process. Given the complexity of science these days, independently recreating every step of a project is too time-consuming. Yes, it is critical to know the fundamentals (do not skip that statistics class), but be efficient where you can be. (3) Open science promotes collaboration, especially across disciplines. Some of the coolest science I have seen is people who adapted methods from other disciplines. This is incredibly hard to do without openly sharing resources, ideas, and methods. (4) Not a benefit, just the bottom line.

摘要

每年,ASLO都会颁发七项成就奖,表彰不同职业阶段的水生科学家对推进湖泊学和海洋学领域的杰出贡献。下面是今年的获奖名单。ASLO获奖者被邀请在ASLO主办的会议上接受他们的奖项,并就他们的工作和职业做一次全体演讲。这些演讲将被录制并添加到我们广泛的YouTube获奖演讲和会议全体会议库中(http://bit.ly/ASLOUTube)。今年,在美国洛杉矶新奥尔良举行的2024年海洋科学会议上,Elizabeth Kujawinski获得了2024年G. Evelyn Hutchinson奖。Robert Chen是2024年Ramón Margalef卓越教育奖的获得者,他将在美国北卡罗来纳州夏洛特市举行的2025年水生科学会议上接受表彰。其余五个奖项在美国威斯康辛州麦迪逊市举行的2024年夏季ASLO会议上颁发。你知道有谁应该获得ASLO奖吗?考虑提名吧!ASLO获奖者仅从会员提交的提名中选出,因此我们需要您的帮助,以填补2025年获奖者的多样化名单。被提名人不需要是ASLO成员。提名期目前开放,将于9月结束(见http://aslo.org/aslo-awards/)。有关颁奖过程的更多信息,请查看威克兰和波拉德(2019)。伊芙琳·哈钦森·阿瓦德伯克:我们和我的实验室团队一起,量化了海水中可能用于微生物交换反应的微小极性代谢物。虽然我们的一些测量目标分子已经被其他人观察到(如氨基酸),但我们的许多测量是在海水中首次进行的,从而为可能成为海洋微生物群落重要货币的分子带来了新的见解。在这方面,我最喜欢的分子是泛酸(维生素B5)。泛酸是辅酶a (CoA)的前体,辅酶a是碳循环的关键中间体,其胞内浓度可以调节许多细胞的碳循环。由于泛酸在细胞基础代谢中的作用,几乎所有生物都能产生泛酸,维生素B5不被认为是微生物之间交换的重要分子,因此在海水中很少测量。在过去的四年中,我们每个月或两个月在北大西洋的百慕大大西洋时间序列研究(BATS)站点测量泛酸浓度。随着时间的推移,泛酸的深度分布非常稳定,在100 m以上浓度升高,中上层浓度下降。使用较新的方法,我们在这些剖面中看到一些结构,表明泛酸浓度随深度的不同而变化。我对确定泛酸浓度的控制因素感兴趣,目的是了解其在财团中的作用及其在海洋表面的周转时间。EBK: C-CoMP具有多方面的使命:(1)充分探索海洋中微生物代谢物网络的复杂性,以了解其在调节碳循环中的作用及其对气候变化的敏感性;(2)在各级教育中普及海洋知识;(3)拓宽海洋科学家的多样性。在我们的科学研究中,我们使用实验室,现场和计算研究相结合,以高分辨率和高效率探索海洋微生物及其在当前和未来环境中的化学影响。我们的教育研究人员研究如何将更多的海洋科学内容引入K-12科学课程,以及如何在本科生、研究生和博士后研究人群中支持新兴的研究事业。此外,我们开发和支持基于课程的本科生研究体验(CUREs),将我们的海洋科学研究带入本科课堂。最后,C-CoMP为博士后学生和博士后学者提供两年的奖学金。我们在团队科学中使用开放科学方法和最佳实践,在C-CoMP中建立公平和包容的文化。如果我们的更新提案成功,十年的C-CoMP将建立一个综合学者和教育工作者的社区,致力于了解我们星球在关键时刻的重要海洋过程。我希望这个社区将准备好解决碳循环的重要问题,特别是影响海洋表面碳通量的微生物代谢物网络的变化率。我希望我们将为K-12课程提供一条途径,将海洋科学知识纳入其中,教育下一代了解海洋对我们地球健康的重要性。最后,我希望下一代的海洋科学家将包括来自不同背景和生活经历的人才,随时准备发挥他们的创造力和聪明才智,以减轻气候变化对海洋生态系统的影响。 EBK:我想了解海洋不同地层中不稳定DOM池中代谢物的周转率。这些速率对于了解不稳定DOM的动态,进而对海洋表面每年碳周转的敏感性至关重要。将这些速率(和相关参数)添加到生物地球化学模型中,将迅速扩展我们探测海洋微生物群复杂性的能力。我的实验室开发了两种测量溶解代谢物的新方法;这些方法使用足够小的样本量,因此它们适合于分解代谢物来源和汇的速率研究。我想训练下一代DOM科学家使用这些方法来回答我们社区在海洋微生物生态学和生物地球化学交叉领域出现的问题。我想不出比让全世界的海洋科学家更好地了解我们的海洋更好的遗产了。雷蒙德·林德曼:很难想出一个令人惊讶的结果,因为有很多。在研究中,你有多种不同类型的分析,涵盖了广泛的生物和化学性质,特别是当它们在时间上如此广泛时,大多数结果是顺序出现的,而不是一次全部出现。例如,当我从拉布拉多海回来时,我迅速测量了第一个DOC(溶解有机碳)和FDOM(荧光溶解有机物质)浓度,但我不得不等待几个月来分析傅里叶变换离子回旋共振质谱样品,再等几个月来分析16S。当我得到16S数据时,关于DOM转换的核心故事正在形成,这个新的分析带来了与化学数据不同的视角,与我们观察到的模式非常吻合。我认为这是最让我惊讶的地方,每次我加入一个新的分析时,它都能在不做过多修改的情况下与现有的故事结合在一起。大约在实验开始两年后,当我测量最后一个DOC样本时,它们都有相同的值,这让我感到惊讶,但仍然有意义。当然,找到正确的方法和分析需要在过程的每一步都花费时间和精力,我需要在如何说明结果以制作一个连贯的故事方面具有创造性。但总的来说,即使采用了如此多样化的分析方法,也没有出现相互矛盾的结果。RL:我认为微生物碳泵(MCP)有很多研究机会,因为有很多未知的东西。当我们阅读有关该主题的文献时,MCP被描述为碳封存的重要途径,在很长一段时间内,它在海洋中建立了巨大的DOC库。然而,我们也需要记住,微生物以这种方式封存碳是例外,而不是常态:大多数有机分子都被纳入生物质或矿化。找出在哪些特定情况下会产生难溶性有机碳(RDOC),将使我们能够计算固存率,并评估这一过程在应对气候变化方面的潜在规模。这个领域的研究也很大程度上是由方法驱动的,我认为我们(科学界)在前进之前需要退后一步,获得更广泛的图景。在最后的思考中,我的研究从生物地球化学、微生物生态学和海洋物理学的多个角度来看待这个问题。我相信未来的突破也需要不同研究领域之间的合作,以更全面地了解MCP。RL:发行是一个艰难的过程,没有捷径。首先,你需要磨练你的写作技巧,尤其是如果英语不是你的母语。你在文章中表达观点的方式和观点本身一样重要:每年有成千上万的水生科学论文发表,你需要你的研究脱颖而出。有很多关于如何写作、如何写科学、写作习惯等方面的优秀书籍。找一本你喜欢阅读和反复阅读的书,这将使你的写作更容易。学会享受写作,它会成为一种负担,但你会感到兴奋。无论你是否留在学术界,你为学习如何成为一名更好的作家所付出的所有努力都会在你的职业生涯中得到数倍的回报。一旦论文写好,所有的共同作者都满意,还有一个同行评议的过程。这很难。通常情况下,审稿人会撕毁你的文章,发现所有不合适的地方,希望能让你的科学和/或故事讲得更好。当你第一次打开评论并通读它们时,你可能会生气,或悲伤,或任何负面情绪。这很正常。 深呼吸,读完并关闭你的文件至少24到48小时;在这种心态下,不会有任何好的结果。当最初的反应消失后,再次打开它,开始编辑你的手稿。我的经验是,当评论者说有些东西不清楚时,我倾向于同意他们的观点。如果你学会欣赏写作,编辑你的手稿以纳入审稿人的评论将会容易得多。然后重复检查所需的次数。我的MCP论文被拒绝了两次,在被接受之前还做了三次分裂的决定。不要因为负面评价而气馁,利用这个机会让你的工作变得更好。雷德菲尔德终身成就奖:如果我回顾我的职业生涯,并试图找出我最大的成就,答案很简单:那就是100多名毕业生(以及更多的本科生),他们通过我们的实验室,在学术界发展了非凡的职业生涯,也在关键的政府、非政府组织或咨询职位上。拿奖的时候,我有时觉得(用加拿大人的比喻)自己就像一个赢得斯坦利杯的NHL曲棍球队的教练,但只有我一个人来到冰上拿奖杯!我的学生和其他合作者的贡献是显著的。如果我应该得到什么奖励的话,那应该是因为我吸引了高度敬业和勤奋的人,他们喜欢做重要的科学研究,和他们在一起很愉快。说到职业生涯的转折点,这是一个团队的努力,那是在我20多岁的时候,酸雨是世界上许多地方的主要环境问题。在此之前,古湖泊学一直被视为一个深奥的领域,被一些人指责只不过是“讲故事”。20世纪80年代的关键问题是:湖泊酸化了吗?如果有,什么时候有,有多少?这是谁的错?一场高度两极化的辩论正在进行。我们中的一些人意识到,如果我们能找到重建几十年和几个世纪以来pH值和相关变化的方法,这些问题可以从沉积记录中得到答案。这是一个繁忙的时期,政策制定者想要结果,想要快速得到结果,因此必须迅速开发和应用高度可靠的方法。这个问题也吸引了不同的科学家,也许最值得注意的是那些具有高度数字技能的科学家,他们将与我们一起开发传递函数和其他多代理方法。古湖泊学家表明,我们的技术是可靠的、可复制的,我们可以回答关键的政策问题。这段时间对我来说也是一个转折点,因为我开始频繁地与媒体合作,接受电视、广播和报纸的采访(那时还没有网络媒体!),谈论我们的研究及其意义。我很快意识到,如果存在信息真空,它很快就会被既得利益集团的观点所填补。科学家们不得不用证据来反驳一厢情愿的想法。这对我来说是一次“火的洗礼”。当时在大学里,情况不同了,你通常需要脸皮很厚——当然,酸生产行业(及其代理人)对你进行了严重的攻击,但在某种程度上,也有来自其他学术界的攻击。我经常听到二手评论,比如“斯莫尔从来没有见过他不喜欢的麦克风。”我当时的观点和现在一样——公众,总的来说,为我们的研究买单,他们有权利知道我们的发现。js:这个项目(Smol 2023)从赢得国际生态研究所奖(https://www.int-res.com/ecology-institute/eci-prize)开始,该奖项的一个方面是在他们的卓越生态学系列(https://www.int-res.com/book-series/excellence-in-ecology-books/ee30/)中写一本书(任何主题)。我一直对北极很感兴趣,因为它是地球上最后一个未被探索的地区之一,去年是我从事北极研究四十周年。考虑到直接湖泊观测的缺乏和极地地区的敏感性,这是应用古湖泊方法的理想地区。在这本13章的书中,一部分是回忆录,一部分是教科书,我讲述了我们利用历史来解决关键环境问题的许多方法。一个压倒一切的主题是气候变化加速作为“威胁倍增器”所起的关键作用。重点研究包括与土著知识持有者和考古学家的合作,跟踪过去的海洋洪水事件,永久冻土融化的影响,来自本地和远处污染源的污染物的影响,以及跟踪鲑鱼和海鸟种群的长期变化。 我强调了使用多种信息来源的重要性,个人关系在成功的合作项目中所起的作用(例如,与同事合作良好,他们也会与你合作良好),以及与北方人民的环境正义有关的问题。js:我在30岁左右的时候被邀请担任《古湖泊学杂志》的创始编辑,在这个职位上我做了20年,然后成为《环境评论》的编辑。在这35年多的时间里,我了解到评论有时是“意见”,不一定是“事实”,而编辑作为看门人,在权衡证据时必须彻底和警惕。你不可能成为一个希望赢得人气竞赛的编辑。作者、审稿人和编辑都是人,通常对什么是正确的有强烈的意见。同行评议的过程虽然有很多挫折,但并不完美,但它是目前最好的系统。我经常发现,ecr是优秀的审稿人——他们通常非常了解最新的文献,并且对推动科学发展有着浓厚的兴趣。是的,我们都很忙,是的,我们很容易按下“拒绝”,但为同行评审过程做出贡献是我们的集体责任。导师在这里也可以发挥关键作用。如果资深科学家无法完成审稿,他们可以建议ecr(编辑可能还不认识)作为替代审稿人。ecr也可以采取积极主动的方式,将他们的简历发送给编辑,注明他们可以在特定领域进行审查。如果你被要求做一篇综述,接受这个角色(如果合适的话),并意识到你的主要工作是指出方法或结论中的错误,并以改进论文为总体目标。记住,批评有建设性的方式。更直白地说,匿名不能成为混蛋的借口!RUTH PATRICK awards:在宾夕法尼亚大学读研究生的时候,RUTH PATRICK博士给了我一本最近发表的小文集。他们描述了大型水坝(冷水)和发电厂(热水)下游河流的非自然热改造是如何消灭当地水生动植物的,尽管致命的最低或最高温度似乎与此无关。鲁斯说:“阅读这些论文,思考这个巨大的环境问题”,“对这个问题提出一个合理的假设,将对湖泊学做出有意义的贡献。”当时,露丝是我的论文导师,所以我非常认真地对待这个挑战。我和Robin Vannote博士讨论了几个想法,他当时也是我的顾问委员会成员,也是Stroud Water研究中心的主任。他认为我最初的想法“太明显了”,“不太可能有成效”,于是鼓励我更广泛、更深入地思考这个问题。我当时的思考和重点是水生昆虫,特别是蜉蝣目,因为它们受到热污染的破坏。此外,蜉蝣非常适合实验室工作,因为一些物种的生命周期很短,所有的成年蜉蝣都很短,而且雌性在产卵时就会变质(因此繁殖力反映了幼虫的饲养条件)。因此,我建议进行实地和实验室研究,包括温度与幼虫生物能量学、发育动力学和生活史现象的生态/生物地理方面的相互作用。经过一系列不同温度条件下的实验(波动和恒定;发表在《生态学》杂志上),并考虑到蜉蝣物种的地理分布,我们(Vannote和我)在《科学》(Sweeney and Vannote 1978)和《美国博物学家》(Vannote and Sweeney 1980)上发表了“热平衡假说”。该假说提出,除其他因素外,由人类或极端的南部或北部地区引起的极端温度模式破坏了物种的代谢、生长和发育动态,因此生命史特征,如个体繁殖力受到损害,导致种群逐渐灭绝。这一成功激发了我去考虑与水生昆虫和溪流和河流生态系统相关的其他问题/挑战,并用良好的科学方法寻求根本的解决方案。我相信我们的领域能够而且应该继续朝着这个方向发展,即在最好的科学基础上寻求答案和方向,并将其作为健全环境政策的基础。BS:我最好的建议是兼收并蓄,也就是说,从广泛和多样化的来源中产生你的想法和方法来理解、评估和解决科学/环境问题。回顾过去,我从与ASLO、淡水科学学会、美国生态学会、进化学会等学会有关的水生期刊上广泛阅读的文章中受益。 然而,在研究生院Robin Vannote的鼓励下,我也养成了一个终生的习惯:浏览《科学》杂志每周的所有文章,同时总是看每一篇摘要、文章或新闻,寻找与水生科学有关的有价值的东西。在研究方法和想法方面,这是一种精神上的刺激和回报,并鼓励我将最新的技术融入到我的实验中。此外,我认为它还帮助我提出了一些关于水生生态系统的问题,这些问题具有前瞻性,而且经常超出常规。BS:对我来说,很难把在研究生院学到的东西和博士学位的东西区分开来。露丝·帕特里克和罗宾·凡诺特。他们都强调有必要了解溪流或河流是如何自然运行的,以便:(1)知道它是否受到了干扰或影响;(二)受影响的程度;(3)如何减轻影响。换句话说,自然系统的基础研究是评价和恢复受干扰/污染系统的关键。罗宾对自然生态系统更感兴趣。露丝总是强调,你可以从仔细研究原始和被污染的水生生态系统中学到很多东西。露丝让你保持警觉。每次经过她身边,她都会问你....之类的问题你今天学了什么新东西?这两天你读了什么令人兴奋的论文,请给我一个三句话的总结。如果她布置了五篇技术论文让你在下节课之前阅读,你最好已经阅读并思考过了,因为她会叫某人(也许是你)站起来,为这五篇论文提供总结和要点。在她的讲座中,露丝强调了水生生态系统的弹性,每个物种都有很强的自我弹性,并共同为生态系统的弹性做出贡献。然而,她警告说,人类影响的强度和频率可能会压倒这种恢复能力。她经常利用实地考察来充分理解她的讲课要点。例如,一个星期天早上,她让我们(研究生)从宾夕法尼亚州一条受到酸性矿污染影响的溪流中收集水,然后我们花了一个下午的时间从新泽西州松树荒地的一条自然溪流中收集水。两流的pH值均为强酸性(~ 3)。从酸矿流中采集到的藻类、大型无脊椎动物和鱼类的个体和种类很少,而从松树贫瘠流中采集到的个体和种类很多。露丝虽然已经六十五岁了,但她穿着短靴站在我们旁边,整天很少说话。在几天结束时,我们报告了我们的发现。没有讨论,她接着说:“女士们先生们,你们现在已经证明了水生物种和生态系统可以适应压力环境(比如低pH值),但如果,只有当,他们有足够的时间……下课。”我从露丝和罗宾那里得到的其他启示是:(1)水生系统具有弹性,因此受污染的水生系统会随着更自然环境的恢复而恢复;(2)生态系统内部和之间的多样性是生态系统稳定性和功能的关键;(3)每个物种都很重要;(4)科学是快节奏的,一个人需要全天候工作才能脱颖而出;(5)把目标定得高,然后努力去实现;(6)不要放弃,只是再努力想想。约翰·h·马丁·阿沃德:在过去的二十年里,围绕湖泊新陈代谢的研究已经发生了很大的变化。最初,该社区专注于部署各种传感器,以估计新陈代谢,特别是溶解氧和温度,以及在某些情况下的气象数据。由于成本和工作量的原因,人们大多在靠近湖面的一个地点和典型的野外季节(夏季)测量这些变量。关于空间异质性的问题出现了,并且出现了一堆关于沿海与远洋代谢以及水柱不同深度的代谢的工作。在具有大量沿海带的湖泊中,空间异质性可能很重要。在分层湖泊中,表层代谢与低表层代谢存在较大差异。同样,随着传感器的部署开始跨越多年,人们开始解决关于季节性和年度代谢规模的重要问题。毫无疑问,在具有强烈季节性模式的湖泊中,湖泊代谢随季节温度、分层模式、可用光照和养分而变化。与此同时,分析模型也在不断发展,包括基于过程的模型的变化,无论是在复杂性方面,还是在与观测数据的拟合方面。有了多年的数据和适应季节性的模型,人们开始质疑整个湖泊的碳预算以及湖泊在景观尺度碳循环中的作用。 最近,人们强调湖泊代谢作为水质的一个框架,因为建模方法有助于估计氧气、颗粒有机碳(藻类生物量指数)和水的清晰度的动态。这三个变量是湖泊营养状态的指标,可以决定例如氧热生境。PH:对我来说,这篇被高度引用的论文最有价值的方面是它所催化的讨论和合作。作为一名读者,我最喜欢的一些论文相对简单,有一个明确的问题和结果,清楚地说明了问题。我觉得我们的论文符合这些标准。我们的论文发表的时候,湖泊学家也能负担得起传感器。我认为我们没有预料到一个简单的科学问题,加上新的和可获得的技术,会在我们的社区中产生如此好的共鸣。PH:全球湖泊生态观测网(GLEON)是由两位湖沼学家David Hamilton和Tim Kratz以及两位计算机科学家Peter Arzberger和Fang-Pang Lin合作建立的。最初的设想是建立一个全球湖泊观测站网络,在湖泊生态系统的广泛梯度上提供跨越新时间尺度的数据。湖泊代谢是一个早期的用例。随着GLEON的迅速发展,湖泊代谢成为其中一个工作组的主题,因为它易于理解,与湖泊和水库的许多问题相关,大量使用常用的测量湖泊变量,并且可以针对不同的问题以不同的方式建模。Lake新陈代谢也有助于促进通用软件代码的开发。GLEON的许多软件工具至今仍在使用,包括LakeMetabolizer。共享想法、技能和资源是glon协作框架的一部分,而湖泊代谢是一个非常适合的想法和方法。对于NTL-LTER,有很多话要说,但我没有空间说,但主题是NTL-LTER使各种创新研究成为可能,包括湖泊代谢。许多湖泊代谢论文都是关于NTL-LTER研究湖泊的,或者由于全面和长期的数据是公开的,因此将它们纳入更广泛的分析。然而,它总是会回到社区。NTL-LTER的同事是一个源源不断的想法、生产力和支持的来源,这导致了许多关于新陈代谢的创造性论文。最近的工作包括湖泊代谢的长期物候,基于代谢框架的富营养化恢复预测,以及使用湖泊代谢训练机器学习模型。RAMÓN玛格丽特卓越教育奖rc:我来自一个教育工作者的家庭。1992年,我加入了马萨诸塞大学波士顿分校的环境科学项目。这是一个研究生课程,但我告诉院长我想教本科生。32年后,我教授全校最大的课程——环境科学导论,有550名学生,这个课程已经成为一个完全独立的环境本科和研究生院。我的第一次拓展探索是在一个大型海洋教育展上,在那里我展示了如何使用激光探测海水中的叶绿素和有色溶解有机物。这是一个巨大的成功,我意识到拓展是我可以做得很好的事情,这可以对公众对海洋科学的理解产生影响。我的第一个大项目是流域综合科学伙伴关系(WISP),我们与三个学区合作,在教室中整合内彭塞特流域周围的资源和活动(https://www.wisp.umb.edu)。WISP得到了NSF GK-12项目的支持,该项目将理科研究生全年安排在中学教室里。通过这个项目,我与波士顿公立学校、中学教师和探究性科学课程密切合作,并为对教学、科学传播和推广感兴趣的科学家开发了专业发展。然后是卓越海洋科学教育中心(COSEE): COSEE新英格兰和COSEE海洋。通过这项工作和我在ASLO教育和参与委员会的服务,我能够与区域和国家的海洋教育专家,国际组织以及来自科学界和非正规和正规教育界的专业人士合作。我们制定了《海洋素养原则》,将海洋课程纳入国家和地方标准,在研究机构中为教育和外联协调员设立了新的职位,并分发了2万多份《COSEE最佳实践活动》(http://www.cosee.net/best_activities)。这项工作产生了两个组织:COSEE China和新英格兰海洋科学合作组织(www.neosec.org)。 波士顿科学伙伴关系是美国国家科学基金会数学科学伙伴关系,我们与波士顿公立学校密切合作,为600多名科学教师提供专业发展,提高了参与我们项目的教师所教学生的标准化考试成绩。“酷科学”是美国国家科学基金会推进非正式科学学习的一个项目,它将艺术和科学结合起来,通过青少年制作有关气候变化的海报,并通过在马萨诸塞州、堪萨斯州和密苏里州的公共汽车上放置获奖作品来教育成年人。教育创新得到了NSF、NASA、ONR和SeaGrant的科学和教育部门的支持,并导致了Stone Foundation和Waverly Street Foundation等基金会的成功整合项目。这些巨额的教育资助资助了我的研究生和实验室,帮助我晋升为正教授,并使我成为教授、院长和社区合作伙伴级别的更好的教育家和科学家(Chen 2008)。我被邀请到新英格兰水族馆、商业领导联盟、气候灯塔和ASLO的董事会任职,因为我在海洋科学和教育之间架起了桥梁。我的许多研究生都从事了有影响力的职业,如具有良好沟通和教学技能的科学家,具有强大科学内容知识和理解的教育工作者,以及我们不知道存在的新的跨学科工作。我的工作跨越,整合和混合科学研究与正式和非正式的STEM和艺术教育在K通过灰色频谱继续....RC:作为提高STEM项目广泛参与的合作伙伴联盟(PATHS; www.pathspartners.org)的一部分,黑人、土著和有色人种(BIPOC)的参与者与由马萨诸塞大学波士顿分校的Shirley Tang博士指导的亚裔美国人数字故事研究小组密切合作。我们通过劳动密集型的合作制作过程与参与者一起制作视频产品,提升BIPOC的声音,培养变革的愿景,并在STEM路径中促进BIPOC的领导地位。2022年6月,在波士顿科学博物馆(Museum of Science)举行的第一届队列首映式上,我有幸与讲故事的人、他们的家人和朋友以及来自波士顿各地的广大观众一起观看了七个视频故事。没有干燥的眼睛在人群中,我站起来,使评论这个问题我现在我经历过的每一次互动与任何我的学生在我的三十五年来,作为一个micro-affirmation与一个micro-aggression可以改变这些有天赋的个体的职业生涯路径:一个微笑在走廊,我匆匆后大类,我为学生提供一个扩展可能每周工作60个小时没有足够的食物吃。我经常想起这一刻,并试图做得更好……去了解我的学生,不要对他们做出假设,赞美他们不同的背景、资产和观点。这些视频故事的节选可以在https://www.pathspartners.org/year1stories.RC:Listen上观看。当你与学生、年轻科学家或社区科学家一起工作时,你应该了解他们,了解他们感兴趣的是什么,是什么驱使他们。通过这种方式,您可以适当地修改您传达科学知识、兴趣和观点的方式。通过仔细地尊重和理解你可能与之合作的特定受众,他们会变得更投入,认为你的科学更相关,有时会受到启发而参与其中。能够向不同的受众解释你的研究是一种可以培养的技能。就像实验室技能和实验一样,熟能生巧。你练习得越多,向非科学家解释你的研究,讲关于海洋科学的故事,尝试新的类比来帮助解释复杂的概念,你就越能在教学、吸引和支持年轻科学家方面做得更好。评估和改进。把你的教室或科学博览会看作是一个实验室,你可以不断提高你的教育和拓展技能。科学家批判性地评估和检查他们的方法和数据,以得出他们的结论并推动他们的科学向前发展;使用持续评估和评价的教育工作者还可以开发可共享的最佳实践和项目,并推动他们的教育和推广工作向前发展。杨施-辛德勒早期职业奖:在我研究这个问题的过程中,看到淡水盐碱化这个话题变得臭名昭著,尤其是在我居住的北美地区,我感到很欣慰。在科学上,我最自豪的是我的现任和前任实验室成员所做的一些惊人的研究。罗伯特·拉德维格在《L&amp;O Letters》上发表了一篇论文,研究了盐碱化对湖泊分层和春季混合的影响。

G. EVELYN HUTCHINSON AWARD

EBK: Together with my lab group, we quantify small polar metabolites in seawater that may be used in exchange reactions between microbes. Although some of our measurements target molecules that have been observed by others (like amino acids), many of our measurements are the first of their kind in seawater and thus bring new insights into the molecules that could be important currencies in marine microbial consortia. My favorite molecule in this context is pantothenic acid (vitamin B5). Pantothenic acid is a precursor to coenzyme A (CoA), a critical intermediate in the carbon cycle, and its intracellular concentrations can regulate carbon cycling in many cells. Because almost all organisms can produce pantothenic acid due to its role in the foundational metabolism of the cell, vitamin B5 was not considered to be an important molecule for exchange among microbes and thus was rarely measured in seawater. Over the past four years, we measured monthly or bi-monthly pantothenic acid concentrations at the Bermuda Atlantic Time-series Study (BATS) site in the North Atlantic Ocean. The depth profile of pantothenic acid is remarkably stable over time, with elevated concentrations in the upper 100 m, and decreasing into the mesopelagic zone. With newer methods, we see some structure in these profiles, indicating that pantothenic acid concentrations are responding to different consortia with depth. I am interested in determining the controlling factors on pantothenic concentrations with the goal of understanding its role in consortia and its turnover time in the surface ocean.

EBK: C-CoMP has a multifaceted mission: (1) to explore the intricacies of the microbe-metabolite network in the ocean sufficiently to understand its role in regulating carbon cycling and its sensitivities to a changing climate; (2) to expand ocean literacy at all education levels; and (3) to broaden the diversity of ocean scientists. In our science research, we use a combination of laboratory, field, and computational studies to explore ocean microbes and their chemical impact at high resolution and efficiency in the current and future environment. Our education researchers study how to bring more ocean science content to K–12 science curricula and how to support emerging research careers within undergraduate, graduate, and postdoctoral research populations. In addition, we develop and support course-based undergraduate research experiences (CUREs) that bring our ocean science research to undergraduate classrooms. Finally, C-CoMP supports two year fellowships for postbaccalaureate students and for postdoctoral scholars. We use open-science approaches and best practices in team science to build a culture of equity and inclusion in C-CoMP.

If we are successful in our renewal proposal, ten years of C-CoMP will build a community of integrated scholars and educators dedicated to understanding important ocean processes at a critical time for our planet. I hope that this community will be ready to tackle important questions of carbon cycling, in particular, the rates of change with the microbe-metabolite network that impact carbon flux in the surface ocean. I hope that we will provide a pathway for K–12 curricula to incorporate ocean science literacy to educate the next generation about the importance of the ocean in our planet's health. Lastly, I hope that the next generation of ocean scientists will include talent from all backgrounds and lived experiences, ready to bring their creativity and ingenuity to mitigating the impacts of climate change on the ocean's ecosystems.

EBK: I would like to understand the rates of turnover of metabolites within the labile DOM pool in different strata of the ocean. These rates are critically important to understanding the dynamics of labile DOM and, by extension, to the sensitivity of the carbon turnover every year in the surface ocean. Adding these rates (and related parameters) to biogeochemical models will rapidly expand our ability to probe the intricacies of the ocean microbiome. My lab has developed two new methods for measuring dissolved metabolites; these methods use sufficiently small sample volumes such that they are suitable for rate studies that disentangle the sources and sinks of metabolites. I would like to train the next generation of DOM scientists to use these methods to answer our community's emerging questions at the intersection of marine microbial ecology and biogeochemistry. I cannot imagine a better legacy than empowering marine scientists across the world to understand our oceans better.

RAYMOND L. LINDEMAN AWARD

RL: It is hard to think of a single surprising result as there were many. In studies where you have multiple different types of analysis covering a wide array of biological and chemical properties, especially when they are so widespread in time, most results come sequentially and not all at once. For example, I measured the first DOC (dissolved organic carbon) and FDOM (fluorescent dissolved organic matter) concentrations rapidly when I came back from the Labrador Sea, but I had to wait a few months to analyze Fourier-transform ion cyclotron resonance mass spectrometry samples and several more months for 16S. By the time I got the 16S data, the core story about DOM transformation was shaping and this new analysis, which brought a different perspective than the chemical data, fit nicely with the patterns that we observed. I think this is what surprised me the most, every time I included a new analysis, it made sense with the existing story without modifying it too much. About two years after starting the experiment when I measured the last DOC samples, they all had the same values which was surprising to me, but still made sense. Of course, finding the right approach and analysis to use took time and efforts at every step of the process and I needed to be creative on how to illustrate the results to make a cohesive story. But overall, there were no conflicting results even with such a diverse array of analyses.

RL: I think the microbial carbon pump (MCP) has a lot of research opportunities as there are so many unknowns. When we read the literature on the subject, the MCP is depicted as an important pathway of carbon sequestration that has, over a long period of time, built up the immense reservoir of DOC in the oceans. However, we also need to remember that carbon sequestrated this way by microbes is the exception, not the norm: most of the organic molecules are incorporated into biomass or mineralized. Finding under which specific circumstances refractory dissolved organic carbon (RDOC) is produced will allow us to calculate the rates of sequestration and assess the potential magnitude of this process in response to climate change. This field of research is also heavily method-driven, and I think we (the scientific community) will need to take a step back to get a broader picture before moving forward. On a final thought, my study looked at the question using multiple angles taken from biogeochemistry, microbial ecology, and ocean physics. I believe that future breakthroughs will also require collaboration among different fields of research to have a more holistic understanding of the MCP.

RL: Publishing is a hard process and there is no shortcut. First, you need to hone your writing skills, especially if English is not your first language. The way you transmit your ideas in an article is as important as the ideas themselves: there are thousands of papers published in aquatic sciences each year and you need your research to stand out. There are numerous excellent books on how to write, how to write science, on writing habits, and so on. Find one that you enjoy reading and re-reading, this will make your own writing much easier. Learn to enjoy writing, it will become less of a burden but something you are excited about. All the efforts that you put in learning how to be a better writer will pay off multiple times over your career, whether you stay in academia or not.

Once the paper is written and all co-authors are happy with it, there is still the peer-review process. And it is hard. More often than not, reviewers will tear down the article and find everything that does not work, hopefully to make your science and/or storytelling better. When you first open the comments and read through them, you will likely get irritated, or sad, or any negative emotion really. That is normal. Take a deep breath, finish reading and close your document for at least twenty-four to forty-eight hours; there is nothing good that will come out of this in this state of mind. When that primal response is gone, open it again and start editing your manuscript. My experience is that I tend to agree with reviewers when they say something is not clear. If you learn to appreciate writing, editing your manuscript to incorporate reviewers' comments will be a lot easier. And then repeat for the number of reviewing rounds that is needed. My MCP paper got two desk rejections, and three split decisions before being accepted. Do not get discouraged with a negative review and use this opportunity to make your work better.

ALFRED C. REDFIELD LIFETIME ACHIEVEMENT AWARD

JS: If I look back at my career and try to identify my biggest achievement, the answer is simple: it is the over 100 graduates (and an even larger number of undergraduates) that have passed through our lab and gone on to develop remarkable careers mainly in academia, but also in key government, NGO, or consultancy positions. When getting an award, I sometimes feel (to use a Canadian analogy) like the coach of an NHL hockey team that wins the Stanley Cup, but only I come onto the ice to hold the trophy! The contributions of my students and other collaborators have been remarkable. If I deserve any award, it should be for attracting highly dedicated and hard-working people, who enjoy doing important science and are a pleasure to be with.

When it comes to career turning points, and again this was very much a team effort, it was when I was still in my 20s, and acid rain was the major environmental issue in many parts of the world. Until then, paleolimnology was very much seen as an esoteric field, accused by some to be little more than “story telling.” Critical questions in the 1980s were: Have lakes acidified? If so, when and by how much? And who was to blame? A highly polarized debate was underway. Several of us realized that these questions could be answered from the sedimentary record if we could develop ways to reconstruct pH and associated changes over decades and centuries. This was a hectic time when policymakers wanted results and wanted them fast, and so highly reliable methods had to be quickly developed and applied. It helped that this issue also attracted diverse scientists, perhaps most notably those with highly developed numerical skills who would work with us to develop transfer functions and other multi-proxy approaches. Paleolimnologists showed that our techniques were robust and reproducible and that we could answer key policy questions.

This time was also a turning point for me as I began working frequently with the media, being interviewed on TV, radio, and newspapers (we did not have online media yet!) about our research and what it meant. I quickly realized that if there was an information vacuum, it would quickly be filled by opinions from vested interest groups. Scientists had to counter wishful thinking with evidence. It was a “baptism of fire” for me at this time. Things were different then in universities, and you often needed a thick skin—well of course there were serious attacks from the acid-producing industries (and their proxies), but also to some extent from other academics. I would hear, often second hand, comments like “Smol never saw a microphone he didn't like.” My view then is the same as it is now—the public, by-and-large, pay for the research we do, and they have a right to know what we found. If we do not transfer that knowledge and fill the information void with accessible language, then it will be filled by others.

JS: This project (Smol 2023) started with winning the International Ecology Institute Prize (https://www.int-res.com/ecology-institute/eci-prize), and one aspect of the award was to write a book (on any topic) in their Excellence in Ecology series (https://www.int-res.com/book-series/excellence-in-ecology-books/ee30/). I was always interested in the Arctic as one of the last largely unexplored areas on the planet, and last year marked my fortieth anniversary of Arctic research. Given the paucity of direct limnological observations, and given the sensitivity of polar regions, it was an ideal region to apply paleolimnological approaches. In this thirteen chapter book, which is part memoir and part textbook, I recounted the many ways we used history to address key environmental issues. An overriding theme is the critical role that accelerated climate change plays as a “threat multiplier.” Highlighted research includes collaborations with Indigenous knowledge holders and archeologists, tracking past ocean flooding events, the repercussions of permafrost thaw, the effects of pollutants from both local and distant sources, as well as tracking long-term changes in salmon and seabird populations. I emphasize the importance of using diverse sources of information, the role that personal relationships can play in successful collaborative programs (i.e., work well with colleagues and they will work well with you), and issues linked to environmental justice for Northern peoples.

JS: I was asked to be the founding editor of the Journal of Paleolimnology when I was ~ thirty years old, a position I held for twenty years, and then became Editor of Environmental Reviews. Over those thirty-five plus years I learned that reviews are at times “opinions” and are not necessarily “facts,” and that editors, as gatekeepers, must be thorough and vigilant in weighing the evidence. You do not become an editor hoping to win popularity contests. Authors, reviewers, and editors are human, and often have strong opinions on what is right. The peer-review process, with all its frustrations, is not perfect, but it is the best system available.

I have often found that ECRs make excellent referees—they often know the recent literature well and have a keen interest in moving science forward. Yes, we are all busy, and yes, it is easy to press “decline,” but it is our collective responsibility to contribute to the peer-review process. Mentors can play a key role here as well. If senior scientists cannot do a review, they can suggest ECRs (whom the editor may not yet know) as alternate referees. ECRs can also take a proactive approach and send their CVs to editors, noting they are available to review in specific areas. If you are asked to do a review, accept the role (if appropriate) and appreciate that your main job is to point out errors in approaches or conclusions, with an overall goal of improving the paper. Remember, there are constructive ways to criticize. Stated more plainly, being anonymous is no excuse for being a jerk!

RUTH PATRICK AWARD

BS: Early in graduate school at the University of Pennsylvania, Dr. Ruth Patrick handed me a small collection of recently published articles. They described how unnatural thermal modification of river reaches downstream of large dams (cold water) and power plants (hot water) was extinguishing the resident aquatic fauna and flora, although lethal minimum or maximum temperatures did not appear to be involved. Ruth said “read the papers and think about this huge environmental problem” and “a reasonable hypothesis for this matter will be a meaningful contribution to limnology.” At the time, Ruth was my thesis advisor so I took this challenge very seriously. I discussed several ideas with Dr. Robin Vannote who was also on my advisory committee and Director of the Stroud Water Research Center at the time. He thought my initial ideas were “too obvious” and “unlikely to be productive” and so challenged me to think more broadly and deeply about the problem. My thinking and emphasis at the time was on aquatic insects, especially mayflies (order Ephemeroptera) because they were being devastated by the thermal pollution. In addition, mayflies were well suited for laboratory work because some species had short life cycles, all were short lived as adults, and females metamorphosed with their full complement of eggs (hence fecundity reflects larval rearing conditions). So, I proposed field and laboratory studies involving the interaction of temperature with larval bioenergetics, developmental dynamics, and the ecological/biogeographical aspects of life history phenomena. After a series of experiments under different temperature regimes (fluctuating and constant; published in L&O and Ecology) and considering the geographic distribution of mayfly species, we (Vannote and me) published the “Thermal Equilibrium Hypothesis” in Science (Sweeney and Vannote 1978) and The American Naturalist (Vannote and Sweeney 1980). The hypothesis proposed, among other things, that extreme temperature patterns caused by humans or by extreme southern or northern locations disrupted a species' metabolic, growth, and developmental dynamics, and hence life history characteristics such that individual fecundity was compromised leading to gradual population extinction. This success inspired me to consider other questions/challenges related to aquatic insects and stream and river ecosystems and seek fundamental solutions with good science. I believe that our field can and should continue to evolve in this direction i.e., seeking answers and direction grounded in the best science and using it as the basis for sound environmental policy.

BS: My best advice is to be eclectic i.e., generate your ideas and approaches to understanding, evaluating, and solving scientific/environmental problems from a broad and diverse range of sources. In looking back, I benefitted from reading a broad spectrum of articles in aquatic journals associated with societies like ASLO, Society for Freshwater Science, the Ecological Society of America, the Society for Evolution. However, with the encouragement of Robin Vannote in graduate school, I also developed a lifelong habit of browsing through all the articles in the weekly issues of the journal Science while always looking at each abstract, article, or news item for something of value or relevance to aquatic science. This was mentally stimulating and rewarding in terms of research approaches and ideas and encouraged me to incorporate the latest technology into my experimentation. Also, I think it helped me pose questions regarding aquatic ecosystems that were forward thinking and often out of the norm.

BS: It is hard for me to separate lessons learned in graduate school from Drs. Ruth Patrick and Robin Vannote. Both always emphasized the need to understand how a stream or river worked naturally in order to: (1) know whether it was disturbed or impacted by something; (2) the degree to which it was impacted; and (3) how to mitigate the impact. In other words, basic research on natural systems was key to evaluating and restoring disturbed/polluted systems. Robin was more interested in natural ecosystems. Ruth always stressed that you could learn a lot from carefully studying both pristine and polluted aquatic ecosystems.

Ruth kept you on your toes. There was no passing by her without her asking you questions like…. What new thing did you learn today? What exciting paper did you read in the last two days and please give me a three-sentence summary? If she assigned five technical papers to read before the next class, you had better have read and thought about them because she was going to call on someone (maybe you) to stand up and provide a summary and take away message for all five. In her lectures, Ruth emphasized the resiliency of aquatic ecosystems, with each species being quite resilient unto itself and collectively contributing to the resiliency of the ecosystem. She cautioned, however, that the magnitude and frequency of human impacts can overwhelm this resiliency. She often used field trips to drive home her lecture points. For example, one Sunday morning she had us (graduate students) collect from a stream in Pennsylvania that was impacted by acid mine pollution and then we spent the afternoon collecting from a natural stream in the New Jersey pine barrens. The pH of both streams was highly acidic (~ 3). We collected very few individuals or species of algae, macroinvertebrates, and fish from the acid mine stream but many individuals and species from the pine barren stream. Ruth collected alongside of us in her hip boots despite being around sixty-five years old but spoke little all day. At days end, we reported out our findings. Without discussion she then said: “Ladies and Gentlemen, you now have demonstrated for yourselves that aquatic species and ecosystems can adapt to stressful situations (like low pH) but if, only if, they are given enough time… class dismissed.” Other take aways for me from Ruth and Robin were: (1) aquatic systems are resilient and so polluted ones will recover with restoration of a more natural setting; (2) diversity within and among trophic levels is the key to ecosystem stability and functionality; (3) each species is important; (4) science is fast paced and one needs to work 24/7 at it to excel; (5) set the bar high and then go for it; and (6) do not give up… just think about it harder.

JOHN H. MARTIN AWARD

PH: Work around the idea of lake metabolism has changed substantially in the past twenty years. Initially, the community focused on deployment of the kinds of sensors needed to estimate metabolism, especially dissolved oxygen and temperature, as well as meteorological data in some cases. Because of the costs and the effort, people mostly measured these variables at one location near the lake surface and during typical field seasons (summer). Questions around spatial heterogeneity arose, and a bunch of work emerged on littoral vs. pelagic metabolism and metabolism at different depths in the water column. In lakes with substantial littoral zones, spatial heterogeneity can matter a lot. In stratified lakes, there are big differences between epilimnetic and hypolimnetic metabolism. Similarly for time, there were important questions about seasonal to annual scales of metabolism that people began addressing as sensor deployments began spanning years. It came as no surprise that in lakes with strong seasonal patterns, lake metabolism varied with seasonal temperature, stratification patterns, and available light and nutrients. Analytical models evolved at the same time to include variations on process-based models, both in their complicatedness and how they were fit to the observational data. With multi-year data and models that accommodated seasonality, people began asking questions about whole lake carbon budgets and the roles lakes play in the landscape-scale carbon cycling. Recently, there has been an emphasis on lake metabolism as a framework for water quality, because the modeling approach lends itself to estimating dynamics of oxygen, particulate organic carbon (index of algal biomass), and water clarity. These three variables are indicators of lake trophic state and can determine, for example, oxythermal habitat.

PH: To me, the most rewarding aspect of this highly cited paper is the discussions and collaborations it has catalyzed. As a reader, some of my favorite papers are relatively simple, with a clear question and results that speak clearly to the question. I feel like our paper meets those criteria. Our paper also came out about the time when sensors were becoming affordable for limnologists. I do not think we anticipated how a simple science question, coupled with new and accessible technologies, would resonate so well with our community.

PH: The Global Lake Ecological Observatory Network (GLEON) started as a collaboration between two limnologists, David Hamilton and Tim Kratz, and two computer scientists, Peter Arzberger and Fang-Pang Lin. The initial vision was to build a global network of lake observatories that would provide data across new time scales over a broad gradient of lake ecosystems. Lake metabolism was an early use-case. As GLEON rapidly grew, lake metabolism became the topic of one of the working groups, because it is easy to understand, is relevant to many questions about lakes and reservoirs, makes great use of commonly measured limnological variables, and can be modeled in different ways towards different problems. Lake metabolism also helped catalyze common software code development. There are a number of software tools from GLEON that are still in use today, including LakeMetabolizer. Sharing ideas, skills, and resources is baked into the GLEON collaborative framework, and lake metabolism is an idea and approach that fits nicely therein. For NTL-LTER, there is more to say than I have space to say it, but the theme is that NTL-LTER enables innovative research of all kinds, including lake metabolism. Many lake metabolism papers are about the NTL-LTER study lakes or include them in more extensive analyses because of the comprehensive and long-term data, which are openly available. However, it always comes back to the community. Colleagues at NTL-LTER are a constant source of ideas, productivity, and support, which has led to many creative papers on metabolism. Most recent work has included long-term phenology of lake metabolism, projections of recovery from eutrophication based on a metabolism framework, and use of lake metabolism to train machine learning models.

RAMÓN MARGALEF AWARD FOR EXCELLENCE IN EDUCATION

RC: I come from a family of educators. I joined the Environmental Sciences Program at University of Massachusetts Boston in 1992. This was a graduate program, but I told the dean that I wanted to teach undergraduate students. Thirty-two years later, I teach the largest class on campus, Introduction to Environmental Science, at five hundred and fifty students, and the program has become a fully independent undergraduate and graduate School for the Environment.

My first exploration of outreach was a large ocean education fair where I showed how lasers could be used to detect chlorophyll and colored dissolved organic matter in seawater. It was a big hit, and I realized outreach was something at which I could be good, and that could make an impact on public understanding of ocean science.

My first big project was the Watershed Integrated Sciences Partnership (WISP), where we worked with three school districts to integrate resources and activities around the Neponset Watershed in the classroom (https://www.wisp.umb.edu). WISP was supported by the NSF GK-12 program, where graduate science students were placed in middle school classrooms throughout the year. Through this project, I worked closely with Boston Public Schools, middle school teachers, and inquiry-based science curriculum, and developed professional development for scientists interested in teaching, science communication, and outreach.

Then there was Centers for Ocean Science Education Excellence (COSEE): COSEE New England and COSEE OCEAN. Through this work and my service on the ASLO Education and Engagement Committee, I was able to collaborate regionally and nationally with ocean education experts, international organizations, and dedicated individuals from the science and informal and formal education communities. We developed the Ocean Literacy Principles, integrated ocean curriculum into national and local standards, created new positions in research organizations for education and outreach coordinators, and distributed over 20,000 copies of the Best of COSEE Hands-On Activities (http://www.cosee.net/best_activities). Two organizations have resulted from this work: COSEE China and the New England Ocean Science Collaborative (www.neosec.org).

The Boston Science Partnership was an NSF Math Science Partnership where we worked closely with Boston Public Schools to offer professional development for over six hundred science teachers that increased the standardized test scores of students who were taught by the teachers who participated in our programs. Cool Science, an NSF Advancing Informal Science Learning program, blends art and science through youth developing posters on climate change and educating adults by placing winning artwork on public buses in Massachusetts, Kansas, and Missouri. Educational innovations were supported from both the science and education divisions within NSF, NASA, ONR, and SeaGrant, and have led to successful integrative projects from Foundations such as the Stone Foundation and Waverly Street Foundation.

These large educational grants helped fund my graduate students and my lab, helped me get promoted to Full Professor, and allowed me to become a better educator and scientist at the professor, dean, and community partner levels (Chen 2008).

I have been invited to serve on the Boards of the New England Aquarium, the Alliance for Business Leadership, Climate Beacon, and ASLO for my work bridging ocean science and education. Many of my graduate students have gone on to impactful careers as scientists with strong communication and teaching skills and educators with strong scientific content knowledge and understanding, and in new transdisciplinary jobs that we did not know existed.

My work crossing, integrating, and blending scientific research with formal and informal STEM and art education across the K through Gray spectrum continues….

RC: As part of the Partners Aligned To Heighten broad participation in STEM program (PATHS; www.pathspartners.org), Black, Indigenous, and People of Color (BIPOC) participants work closely with the Digital Storytelling in Asian American Studies Team supervised by Dr. Shirley Tang at University of Massachusetts Boston. We lift up BIPOC voices, foster visions for change, and promote BIPOC leadership within STEM pathways as we create video products with participants through a labor-intensive co-production process.

At the first cohort's premier event in June 2022 at the Museum of Science in Boston, I had the privilege to view seven video stories with storytellers, their families and friends, and a broad audience from across Boston. Without a dry eye in the crowd, I stood up and made the comment that I now question every interaction I have ever had with any of my students over my last thirty-five years, as one micro-affirmation vs. one micro-aggression could change the career pathway of any of these gifted individuals: a smile in the hallway, my hurrying off after my big class, my providing an extension for a student who may be working sixty hours per week without enough food to eat. I think about this moment often, and try to do better… to get to know my students, to not make assumptions about them, to celebrate their diverse backgrounds, assets, and perspectives. Excerpts from these video stories can be viewed at: https://www.pathspartners.org/year1stories.

RC:

Listen. When you are working with students, young scientists, or community scientists, you should get to know them as individuals, what interests them, what drives them. In this way, you can modify appropriately the way you convey your scientific knowledge, interests, and perspectives. By carefully respecting and understanding the specific audience that you might be working with, they will become more engaged, see your science as more relevant, and will sometimes be inspired to get involved.

Practice. Being able to explain your research to diverse audiences is a skill that can be developed. Just as with lab skills and experimentation, practice makes better. The more you practice explaining your research to non-scientists, telling stories about ocean science, and trying new analogies that can help explain complex concepts, the better you can become at teaching, engaging, and supporting young scientists.

Assess and improve. By viewing your classroom or science fair as a laboratory, you can continually improve your education and outreach skills. Scientists critically evaluation and examine their methods and data to come to their conclusions and move their science forward; educators that use constant assessment and evaluation can also develop sharable best practices and programs and move their education and outreach forward.

YENTSCH-SCHINDLER EARLY CAREER AWARD

HD: Throughout the time I have worked on the issue, it is been rewarding to see the topic of freshwater salinization gain notoriety, especially in the region of North America I live in. Scientifically I am most proud of some of the amazing research carried out by my current and former lab members. Robert Ladwig led a paper in L&O Letters examining the impact of salinization on lake stratification and spring mixing. In my mind it is a perfect example of blending empirical observations, analytical approaches, and detailed simulations to tackle a problem (Ladwig et al. 2023). Linnea Rock carried out an intensive two-year sampling campaign (during covid) to show that lakes fundamentally alter the salinity regimes of downstream rivers (Rock and Dugan 2023). Lindsay Platt is currently wrapping up a project leveraging USGS stream data. Her public workflow is a masterpiece of reproducible research that can be leveraged by others to tackle big water questions.

HD: I certainly try to. I have learned over the years that open science has many benefits. (1) It enhances the quality of science. Transparency allows for increased scrutiny of research findings, by both you and scientific reviewers, which leads to more robust research papers. (2) It saves time, especially for the future-you. Having clean data and code that can be reused and quickly understood streamlines the scientific process. Given the complexity of science these days, independently recreating every step of a project is too time-consuming. Yes, it is critical to know the fundamentals (do not skip that statistics class), but be efficient where you can be. (3) Open science promotes collaboration, especially across disciplines. Some of the coolest science I have seen is people who adapted methods from other disciplines. This is incredibly hard to do without openly sharing resources, ideas, and methods. (4) Not a benefit, just the bottom line. If your data was publicly funded, it should be publicly accessible.

Looking ahead, open science will continue to grow, especially with the upcoming cohort of scientists trained in the principles of open science. Still, it is not easy. It takes time, perseverance, and commitment, and none of us do it perfectly. But ultimately, it democratizes access to knowledge and will drive innovation.
