Eddies are crucial to energy transfer and ocean circulation. The Bay of Bengal (BoB) is a naturally suitable location for intense eddy activity because of its distinct geographical and meteorological characteristics. Using a high-resolution regional ocean model, the mesoscale eddies in the BoB were detected, and their variability was examined in the current study. The model results show good agreement with the available observations. Both geometrical and dynamical approaches are used to identify and track the eddies, which aids in the removal of the frontal jets. The seasonal distribution of eddies, their spatial features, and propagation pathways are investigated. Following the identification and separation of the cyclonic eddy (CE) from the anticyclonic eddy (AE), the kinetic energy of each individual eddy is computed. In the western BoB, the variability of the East India Coastal Current (EICC) dictates eddy generation. The river discharge and bathymetry play a crucial role in determining eddy formation and its features in the northern BoB. Throughout the year, the radius of AEs is greater than that of CEs, reaching its maximum during the pre-monsoon (MAM) season. Compared to CEs, there is a stronger correlation between the size and energy of AEs. Eddie's share of the BoB's overall kinetic energy fluctuates from 7.2 % in March to 19.1 % in November. The seasonal contribution of eddies to the eddy kinetic energy (EKE) of the BoB is discussed, along with the varying strength and direction of winds and surface currents.</div></div>","PeriodicalId":21070,"journal":{"name":"Regional Studies in Marine Science","volume":"89 ","pages":"Article 104329"},"PeriodicalIF":2.1,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144596023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the occurrence, levels, composition, and potential ecological risks of polycyclic aromatic hydrocarbons (PAHs) in surface sediments of mangroves affected by the spill along the coast of Bahia, NE Brazil. Fifty-one samples were collected across seven sites, including oil-impacted areas, a control site, and a chronically contaminated area, during three campaigns conducted 12, 18, and 24 months after the spill. Total PAH concentrations (∑16 PAHs) ranged from 39.1 to 595.4 ng g⁻¹ and fell within low to moderate contamination levels. Despite a general decreasing trend over time, spatial and temporal patterns were inconsistent, and PAH distributions appeared to be influenced by both the oil spill and local anthropogenic inputs. Higher alkyl-PAHs/parent-PAHs ratios in Siribinha and Boipeba suggest a long-term influence of petrogenic sources linked to the oil spill, while elevated PAHs in the São Paulo River reflect chronic industrial and urban pollution. Diagnostic ratios and compositional profiles confirmed mixed pyrogenic and petrogenic signatures across sites. Although mean sediment quality guideline quotients indicated low ecotoxicological risk overall, exceedances of threshold values for acenaphthylene and phenanthrene at some sites, particularly those inhabited by traditional communities, highlight the importance of continued monitoring.
