In this study, we combined a fluorescence model with a modified version of the Garver-Siegel-Maritorena (GSM) algorithm to retrieve the chlorophyll a concentration (Chla) and the magnitude of fluorescence in coastal waters. An analytical inverse optimization procedure was performed using the measured reflectance over the whole visible spectrum with a focus on the Ocean and Land Color Instrument (OLCI) sensor (from 413 to 709 nm). The coupled visible-infrared model (GSM&Fluo) was validated by a comparison with Chla that was measured in situ in a wide variety of productive coastal water conditions in the South China Sea. The coefficients of determination (r2) were 0.79 and 0.88 for the GSM and our algorithm, respectively. The combined approach produced more accurate results in our study location. The coupled GSM&Fluo model was able to avoid being trapped in a local optimum by adding an estimation of the fluorescence signal. The results also showed that the suspended particulate matter (SPM) played a major role in the magnitude of the reflectance peak in the chlorophyll fluorescence emission band, and the Fluorescence Line Height (FLH) calculated with a simple baseline approach tended to overestimate the true magnitude of the fluorescence emission as SPM increased.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70883108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evidence suggesting the population is producing an extreme proportion of females due to increasing temperatures, coupled with temperature-dependent sex determination, is concerning. In response, and to explore management options, we developed two density-independent, stochastic stage-structured metapopulation models: a “Moderate Climate Model” and an “Extreme Climate Model”. The models differ based on climate change projections by incorporating increased female hatchling sex ratios due to global warming and loss of nesting habitat due to sea level rise. The models were based on demographic data from field studies at major rookeries and regional foraging grounds and allowed for variation in operational sex ratios, management actions, and levels of indigenous harvest. Under the Moderate Climate Model, population size increased but could be vulnerable to overharvest of adult females. If overharvest was indicated, the harvest of a proportion of subadults rather than only adult females reduced population declines. Under the Extreme Climate Model, there was a steep population decline even without any harvest, and harvesting subadults accelerated population decline due to the inclusion of subadult males. In the Extreme Climate Model, reversal of population decline depended on male turtles mating with an increased number of females, or management actions to substantially increase the number of male hatchlings produced.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70883577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beyond those on drift algae, there are relatively few studies describing the fauna associated with ephemeral habitats and the functions these habitats maintain in estuarine systems. Given the highly structured morphology of bryozoans and the muddy-bottom seascape of the north-central Gulf of Mexico, we hypothesized that the presence of bryozoans in nearshore waters provides additional temporally and spatially ephemeral habitat for invertebrates, small mobile fishes, or early life-stages of estuarine nekton. We examined seine and trawl samples from a long-term fisheries monitoring program operating within Mississippi Sound, Mississippi to test our hypothesis. Overall, we collected 71 and 85 invertebrate taxa in seine (2012–2017) and trawl (2013–2017) samples, respectively, with 40 taxa in common. We also collected 86 and 74 fish taxa overall in all seine (2012–2017) and trawl (2013–2017) samples, respectively, with 53 taxa in common. We documented highest species richness and species diversity indices when bryozoans were present and in large volumes; however, most of the samples with bryozoans present were collected between September and November. Our results suggest bryozoan mats likely serve as a dispersal mechanism and refugia for estuarine nekton within a soft-sediment seascape as mats pulse shoreward with winds, tides, and currents.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70883614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on a one-year simulation in which a Loop Current and its eddy intruded on the WFS, either the increase of freshwater discharge or the climate warming led to a change in the stratification properties of the West Florida Shelf significant enough to affect the type of Loop Current intrusions. Increased freshwater discharge contributed to the intensification of shelf water mixing that favors surface intrusion of Loop Current waters. On the contrary, 1 °C warming led to increased shelf waters stratification that favors bottom intrusions. Either type of intrusion leads to a different oceanographic regime on the shelf to which the ecosystem might respond differently. Our study suggests, however, that increased freshwater discharge could mitigate the effect of climate warming on the WFS by reducing shelf waters stratification. The WFS response to cold air outbreaks that are common in the fall and winter months was also analyzed. It showed that under a warmer climate, the increased stratification due to the freshwater discharge at the end the boreal summer wet season is cancelled by the warmer climate and reduces the available potential energy on the shelf, limiting coastal upwelling, instabilities, and shelf convection.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70884039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this gap, trophic guilds and dietary patterns were elucidated for 39 species of a juvenile-dominated demersal estuarine fish community in the Matang Mangrove Forest Reserve, an Important Marine Mammal Area. Fish were sampled monthly for a year using otter trawl, and stomach contents were analyzed. Of the seven trophic guilds identified from clustering analysis, the three most speciose ones were shrimp feeders (12 species), zooplanktivores (9), and generalist crustacivores (7). Copepods occurred in diets of 50% of all fish species and were the most important food item volumetrically for specialist zooplanktivores. Diverse shrimp and prawn taxa, including commercially valuable Acetes and juvenile penaeids, showed highest frequency of occurrence in stomachs and supported the shrimp feeder and crustacivore guilds that contained relatively more diet generalists. Biomass-dominant annelidivore guild members are known to be a vital food resource for highly threatened coastal cetaceans. Ontogenetic diet shift, wide intra-guild diet breadth, seasonality in major resource use, and prevalence of detritus in diet were feeding strategies that reduced niche overlap and competition among fish species sharing common food resources. Future fisheries management must consider the bottom-up trophic impacts from excessive removal of valuable prey resources such as shrimps on equally valuable fish consumers that depend on them.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70884141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
