We found that OA enhanced its specific growth rate (up to 10%) in the light period by upregulating light reaction, Calvin cycle and H + pumps to cope with the decreased pH. On the other hand, OA reduced its apparent specific growth rate (14%) in the dark period due to additive pH drop caused by OA‐enhanced respiratory CO 2 release. In the dark period, the cells could not effectively cope with the decreased pH since H + pumps were downregulated. Consequently, OA did not affect cell growth during a 24 h diel cycle. These findings suggest that daytime positive and night negative effects of OA on diatoms could be responsible for differential results observed under different conditions, with implications for possible seasonal and latitudinal effects of OA.","PeriodicalId":18128,"journal":{"name":"Limnology and Oceanography Letters","volume":"259 1","pages":""},"PeriodicalIF":7.8,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the ocean's crucial role in regulating atmospheric H2, its marine biogeochemical cycle is poorly constrained. To bridge this gap, our research in the Western Tropical Pacific Ocean (WTPO) revealed a north–south increasing gradient in the surface (1.40–23.4 nmol L−1). Key processes encompassing photo-production (1.43–4.36 nmol L−1 h−1), microbial consumption (0.57–1.92 nmol L−1 h−1), and sea-to-air exchange (1.19–11.3 × 10−3 nmol L−1 h−1) were conducted to refine the budget estimation for the mixed layer. The highest photo-production and consumption rates occurred at equatorial stations driven by La Niña–induced upwelling that supplied nutrients and organic matter. The sea–air flux in the WTPO was large enough to influence the turnover of atmospheric H2 above the ocean. This research provides critical constraints for assessing oceanic H2 emission and environmental impact.","PeriodicalId":18128,"journal":{"name":"Limnology and Oceanography Letters","volume":"11 3","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://aslopubs.onlinelibrary.wiley.com/doi/epdf/10.1002/lol2.70120","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147586156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Temporal dynamics of animals within eddies—particularly at mid-trophic levels—remain largely unresolved. We tracked a long-lived anticyclonic eddy in the Northeast Atlantic for nearly a month using a Lagrangian framework, generating one of the few continuous time series of mesopelagic fish distribution within an eddy. Coupled physical–biological observations revealed marked vertical changes following a major wind storm: compact fish aggregations dispersed as phytoplankton distributions expanded and zooplankton deepened, despite comparable integrated fish biomass before and after. These results show that aggregation dynamics of mesopelagic fishes are modulated by bottom-up variability on weekly to monthly timescales. By moving beyond static snapshots, our study demonstrates that eddies function as dynamic ecosystems whose ecological roles in pelagic food webs evolve through time.","PeriodicalId":18128,"journal":{"name":"Limnology and Oceanography Letters","volume":"11 3","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://aslopubs.onlinelibrary.wiley.com/doi/epdf/10.1002/lol2.70113","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147586160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
