However, their sources have never been quantified systematically. Seawater has long been deemed their major source, whereas atmospheric deposition is regarded as trivial or merely providing additional nutrients. Here, combining atmospheric observations and quantitative budget analyses, we show that during the Indonesian peatland wildfire events the smoke can directly deposit abundant microbes into the SML, which can be comparable to the estimated supply from seawater and potentially diversify the microbial community of the SML. This land–air–ocean interaction is relevant for global climate, as it may induce previously unknown effects on the air–sea interactions, especially in an increasingly warming future with more intensifying wildfires.","PeriodicalId":18143,"journal":{"name":"Limnology and Oceanography","volume":"70 6","pages":"1770-1781"},"PeriodicalIF":3.8,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 cluster analysis, four different marine submerged vegetation community figurations were identified: a southern and deeper kelp forest including Laminaria solidungula and Agarum clathratum, the marine vegetation along the Blosseville coast, seaweed meadows characterized by, e.g., submerged Fucus distichus, and high-arctic kelp forest. The habitat figurations were related to and potentially explained by drivers considered to be key for their spatial distribution. The drivers considered were latitude as a proxy for light conditions with stronger seasonality and receding light conditions toward the north, suitable substratum for the marine vegetation to establish and grow, and the sea ice conditions with respect to light attenuation and scouring. Two of the vegetation types were explained by latitude, whereas the two vegetation types identified for the mid segment of the surveyed coastline were considered to be more correlated to local/regional conditions such as the presence of dynamic sea ice and glaciers as well as smaller-sized hard substratum. Some degree of marine vegetation/kelp forest pauperization was observed with increasing latitude, expressed as a decrease in coverage and depth distribution. The vegetation belt was declining from a depth of 34 to 18 m within the northward latitudinal gradient surveyed, although for some species, no change in species-specific maximal depth limits could be observed.","PeriodicalId":18143,"journal":{"name":"Limnology and Oceanography","volume":"70 6","pages":"1575-1590"},"PeriodicalIF":3.8,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/lno.70056","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several studies emphasize the critical role of anaerobic microbial metabolism as a major source of total alkalinity (TA) generation in marsh soils. However, the contribution of mineral dissolution to salt marsh TA generation has yet to be extensively studied from a mechanistic viewpoint. Therefore, we conducted a lab-based soil column experiment to investigate the influence of soil pCO2 levels on TA generation in organic-poor minerogenic salt marsh soils, considering their significance in soil mineral dissolution. Results showed a maximum TA increase of up to twofold when the pCO2 level was increased from 440 to 150,000 μatm. The relationship between TA and net Ca2+ release was 1.73, close to the theoretical stoichiometric ratio of HCO3− to Ca2+ for calcium carbonate dissolution. In addition, the net release of dissolved silica responded significantly to the change in soil pCO2. Therefore, calcium carbonate dissolution was identified as the possible dominant driving force behind TA generation in the minerogenic salt marsh soil, with an additional contribution from silicate minerals. We suggest high pCO2 levels, such as the rhizosphere, might be the hotspot for alkalinity generation via mineral dissolution. Our findings advance the mechanistic understanding of TA generation in salt marshes and highlight the importance of the overlooked role of inorganic carbon. Evaluating the contribution of blue carbon ecosystems to alkalinity production is essential for integrating the roles of both organic and inorganic carbon into climate mitigation assessments.","PeriodicalId":18143,"journal":{"name":"Limnology and Oceanography","volume":"70 6","pages":"1591-1605"},"PeriodicalIF":3.8,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/lno.70062","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Measurements of potential CH4 production rates in the sediment can help constrain the magnitude of CH4 sources and time-averaged emission rates. We explored the magnitude, variability, and drivers of potential CH4 production rates in the sediment, based on compiled measurements (238 sediment cores from 72 aquatic systems) following a standardized laboratory incubation procedure. The data reveal > 4-fold higher potential CH4 production rates in reservoir sediments than lakes and > 14-fold higher than rivers after being standardized for temperature. Sediment organic carbon content and depth below the sediment–water interface are universal drivers for potential CH4 production rates across freshwater ecosystems. The disproportional high CH4 production rate in sediments from human-made water bodies calls for more comprehensive monitoring of their CH4 emissions to inform carbon footprint and inventory efforts. This first meta-analysis of potential CH4 production rates in sediments from different types of freshwater aquatic systems may help with process-based modeling of CH4 emissions from individual water bodies in larger-scale assessments.","PeriodicalId":18143,"journal":{"name":"Limnology and Oceanography","volume":"70 6","pages":"1561-1574"},"PeriodicalIF":3.8,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143832519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
