Here, a comparative analysis of pore water profiles of redox-sensitive chemical species reveals the biogeochemical restructuring that occurred over a summer-spring-summer sequence on the Louisiana continental shelf in the northern Gulf of Mexico. Increases in depth-averaged pore water inventories, including exceptionally high Mn(II) concentrations, were associated with high river discharge and sediment inputs, suggesting that Mn reduction plays an important role in Louisiana continental shelf sediments, except during below-average discharge periods in summer when iron and sulfate reduction are promoted. The river effect was greatest and most consistent proximal to the Mississippi River and extended at least ∼60 km westward when high winds and discharge enhanced plume dispersal, whereas the area where seasonal bottom water hypoxia often develops remained largely isolated from any riverine influence. A river imprint on biogeochemical patterns was also observed south of Atchafalaya Bay, suggesting the area periodically receives inputs from the bay throughout the year. Results demonstrate that Mn(II) often traces these hydrodynamic processes and that river loads of Mn (oxyhydr)oxides buffer the redox state of shelf sediments and moderate the biogeochemical response to low discharge and hypoxia. Stores of river-derived Mn may therefore function as an environmental redox capacitor. Based on the patterns observed between the two summers, a period of Mn reduction may persist for ∼20 days after Mississippi River discharge subsides to below the threshold for net mobilization of sediment to the shelf.</div></div>","PeriodicalId":18219,"journal":{"name":"Marine Chemistry","volume":"277 ","pages":"Article 104660"},"PeriodicalIF":2.5,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148499590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The highest levels and rate of increase in anthropogenic aerosols were reported over the Bay of Bengal, compared to the elsewhere in the globe, and it is hypothesised that their deposition may enhance nutrients and surface primary production in the Bay of Bengal. To examine this, aerosol samples were collected at a monthly interval, along with primary production incubation experiments in the coastal Bay of Bengal, off Visakhapatnam. The concentrations of nitrate (0.02–0.35 μmol m⁻³), ammonium (0.01–1.31 μmol m⁻³), and dissolved organic nitrogen (DON; 0.02–0.32 μmol m⁻³) showed significant temporal variability in the aerosols. The atmospheric nitrogen mainly originated from biomass burning, vehicular and industrial emissions, with large seasonality associated with seasonal reversing winds. Dry depositional flux of inorganic nitrogen was higher in the coastal compared to the offshore Bay of Bengal, supporting 14–42% (mean of 30 ± 9%) of primary production in the surface ocean. This contribution is notably higher than global estimates in other marine regions, associated with the highest aerosol optical depth, highlighting the regional importance of atmospheric nutrient inputs. These results provide strong evidence that atmospheric deposition is a significant nutrient source influencing coastal productivity in the central east coast of India with large seasonality driven by different sources. Therefore, it is strongly recommend to incorporate the atmospheric sources of nitrogen in the numerical models for accurate simulation of nitrogen and carbon cycling in the north Indian Ocean.</div></div>","PeriodicalId":18219,"journal":{"name":"Marine Chemistry","volume":"277 ","pages":"Article 104662"},"PeriodicalIF":2.5,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148499592","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}

Here, we present measurements of total DON and solid-phase extracted DON (SPE-DON) concentrations and δ¹⁵N values from sampling sites across the global ocean. An optimized SPE protocol was developed to maximize total DON recovery, with a recovery of 41.0 ± 9.4% for surface DON across the global ocean and 56.6 ± 11.2% for deep water DON from the Sargasso Sea. SPE-DON concentrations were 1.8–1.9 μM across most sampling sites, in contrast to greater variation in total DON concentration (4.0–5.9 μM). However, in the equatorial upwelling zones, SPE-DON concentrations were slightly (0.3–0.4 μM) higher than in other regions. The δ¹⁵N of total DON in surface waters correlated well with the δ¹⁵N of nitrate supplied to the euphotic zone from the subsurface. SPE-DON δ¹⁵N was also correlated with nitrate δ¹⁵N, but SPE-DON δ¹⁵N values were confined to a narrower range compared to those of total DON. The combined concentration and δ¹⁵N data indicate that while SPE-DON is biased toward long-lived DON, it still retains some reactive components introduced through regional inputs in the upper ocean, and even some of its longer-lived components may be labile on the timescales of deep ocean circulation. The longer average turnover time of SPE-DON suggests that greater molecular polarity and/or charge directly increase or are otherwise correlated with the biogeochemical lability of different DON pools.</div></div>","PeriodicalId":18219,"journal":{"name":"Marine Chemistry","volume":"276 ","pages":"Article 104646"},"PeriodicalIF":2.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147956555","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}

Along I09N, high particulate Al and Fe concentrations are found throughout the Bay of Bengal and the northern Indian Ocean indicating significant lithogenic particle loads from river-borne sediment transport and smaller contributions from continental dust flux than current model estimates. Particles have elevated Fe:Al ratios compared to the composition of local shelf sediments, indicating that suspended particulate matter becomes enriched from scavenging of dissolved Fe that accumulates in the oxygen minimum zone in the Bay of Bengal. Along I05, retroflection of the Agulhas Return Current transports African shelf-derived lithogenic particles into the western South Indian basin, resulting in the elevated subsurface concentrations of particulate Al and Fe nearly 3000 km into the interior of the subtropical gyre.
