Transcriptomic and metabolomic analyses revealed at 24 °C, pathways related to steroid hormone biosynthesis, estrogen signaling, and progesterone, androgen, and estrogen receptor agonists/antagonists were activated, whereas at 27 °C, activation was prominent in steroid hormone biosynthesis, steroid biosynthesis, and cholesterol metabolism.

This study quantitatively analyzed the movement, retention, and seaward exit of GPS-tracked drifters in response to seasonal variations in freshwater discharge and tides in the coastal waters near Ganghwa Island. A total of 49 drifters were deployed at three stations over a six-month period, and their trajectories were assessed in relation to changes in discharge and tidal conditions. Most drifters remained confined within the narrow channels near Ganghwa for over a month due to tidal influence and repeated grounding–refloating cycles. Only about 12 % exited the estuary, primarily during periods of high freshwater discharge (top 5 %), through the northern Ganghwa channel. During lower discharge periods, drifters tended to stay near intertidal zones or became immobilized after grounding. Drifter movement was most active during spring tides or during transitions to neap tides, with current velocities nearly twice as high during spring tides. Notably, seaward exit also occurred under neap tide conditions when intertidal exposure was reduced. These findings suggest that the transport and retention of marine debris are governed by the combined effects of freshwater inflow, tidal cycles, and geomorphology. The results provide a scientific basis for modeling debris dynamics and inform environmental management strategies for the Han River estuary and surrounding areas.</div></div>","PeriodicalId":18215,"journal":{"name":"Marine pollution bulletin","volume":"222 ","pages":"Article 118670"},"PeriodicalIF":4.9,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145086515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 evaluates the accuracy of a physics-based noise modeling framework in this environment by comparing modeled sound pressure levels (SPLs) with in situ acoustic measurements. Broadband (40–150 Hz) shipping and wind-driven noise was modeled using Automatic Identification System (AIS) data, the Hildebrand wind noise model, and parabolic equation-based acoustic propagation (RAM), with source levels parameterized for each vessel. Six autonomous acoustic recorders were deployed at two locations (King Abdullah Economic City and Al Fahal), covering both shallow and deep sites during two 12-day periods in summer and winter. Model predictions were compared against measured SPLs in both time and frequency domains. The results demonstrate strong seasonal and spatial variability in underwater noise levels, with modeled median SPLs closely matching observations at most sites. The analysis reveals that ship traffic is the dominant source of underwater noise, while other sources such as winds that were explicitly accounted in the simulations, showed a minimal contributions. Additionally, the findings suggest a seasonal influence on propagation conditions. Despite the inability to model certain biological or other non-shipping noise sources, the validation confirms that the model robustly captures dominant trends in low-frequency noise. The findings support the use of this modeling approach as a reliable basis for regional noise mapping and future marine spatial planning and mitigation efforts in the Red Sea.</div></div>","PeriodicalId":18215,"journal":{"name":"Marine pollution bulletin","volume":"222 ","pages":"Article 118698"},"PeriodicalIF":4.9,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145085204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Statistically significant seasonal differences (<em>p</em> &lt; 0.05) were observed in the concentrations of most metal(oid)s.
