However, the transport dynamics and coastal fate of these carbon associated with large river plumes on the adjacent shelves remain largely unknown, particularly under large-scale climate patterns like the Arctic Oscillation (AO). In this study, we analyzed the interannual variation of particulate organic carbon (POC) and hydrological properties on the Eurasian Arctic Shelf (EAS) during summer to examine the influence of AO on the coastal dispersal of POC in the EAS. Our results revealed interannual spatial heterogeneity in highly depleted δ<sup>13</sup>C<sub>POC</sub> values in the Laptev Sea under varying atmospheric conditions. This significant depletion of δ<sup>13</sup>C<sub>POC</sub> could be attributed to the selective dispersal of aquatic biomass POC, coupled with rapid settlement of mineral-rich POC, as indicated by the relationship between δ<sup>13</sup>C<sub>POC</sub> and salinity within the Lena plume. Therefore, variations in the pathways of river plumes, driven by atmospheric forcing under the annual AO regime, could not only affect the hydrological regime of the Laptev Sea but also modulate the dispersal and dynamics of POC in the EAS. Our findings are crucial for understanding the biogeochemical behavior of terrigenous POC and its impact on the future carbon cycle and coastal ecosystem in the Arctic margins, particularly in the context of recent warming and a positive trend of AO.</div></div>","PeriodicalId":20620,"journal":{"name":"Progress in Oceanography","volume":"234 ","pages":"Article 103468"},"PeriodicalIF":3.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To aid decision making in a rapidly warming ocean, researchers have developed new forecast tools that can predict marine heatwaves on sub-seasonal to seasonal timescales. As demand from marine stakeholders increases for actionable information, effective transfer is paramount for uptake and response. Here we consider three aspects critical to aid this information transfer. The model system must be <u>useful</u> – having the appropriate model type, resolution, and domain, with model skill verified against observations. The forecasts must be <u>useable</u> with skill on timescales relevant to decision making, interpretable by end users, and delivered in a practical format. The forecast information must be <u>used</u>, which requires clear communication at appropriate levels, strong user engagement, and consideration of industry agility and incentives. Feedback between these three aspects is needed to ensure continuous improvement in the level of forecast usefulness, useability, and uptake. Forecasts are a critical tool in the management of climate risk and the framework we present here will be important for maintaining profitable and sustainable marine industries into the future.</div></div>","PeriodicalId":20620,"journal":{"name":"Progress in Oceanography","volume":"234 ","pages":"Article 103464"},"PeriodicalIF":3.8,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
