However, little is known about their seasonal and spatial distributions in the southern Yellow Sea and East China Sea. This study aimed to identify the seasonal and spatial distributions of <em>A. fangsiao</em> and <em>O. variabilis</em>, explore potential relationships with environmental variables, and predict annual mean habitat variations under different climate scenarios. Our findings revealed that <em>A. fangsiao</em> was concentrated in the southern Yellow Sea in spring, in the Zhoushan fishing ground near the Yangtze River Estuary in summer, expanded to the entire East China Sea in autumn, and migrated offshore in winter. In contrast, <em>O. variabilis</em> was concentrated in the Zhoushan fishing grounds in spring, moved eastward in summer, shifted southward to the Yushan fishing grounds in autumn, and moved farther south to the Yushan-Wentai-Mindong fishing grounds in winter. Additionally, we predicted the most suitable sea bottom temperature (SBT) for <em>A. fangsiao</em> to be 10–25°C, with sea bottom salinity (SBS) of 29–31 ‰, whereas for <em>O. variabilis</em>, the most suitable SBT was 27°C, with an SBS of 34–35 ‰. Our results showed that under different climate change scenarios, the annual mean habitat area of <em>A. fangsiao</em> will decrease under SSP1–2.6 by 2050, and increase under SSP1–2.6 by 2100, whereas the area will shrink significantly under the SSP5–5.8 scenario by both 2050 and 2100. Moreover, the annual mean habitat of <em>O. variabilis</em> will shift northward offshore under SSP1–2.6 scenario by 2050 and 2100, as well as under SSP5–8.5 by 2050, but will shrink significantly under SSP5–8.5 by 2100. These results may provide guidance for sustainable fishing and management of both species by specifically incorporating climate change.</div></div>","PeriodicalId":21070,"journal":{"name":"Regional Studies in Marine Science","volume":"83 ","pages":"Article 104072"},"PeriodicalIF":2.1,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143437192","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}

For that, time series of bulk wave parameters and wave spectra covering the period from 1996 to 2020 were analyzed. Results revealed that 57 % of the spectra exhibit double peaks indicating the prevalence of simultaneous wind-sea and swell events. To differentiate between wind-waves and swell cases, the Pierson–Moskowitz (PM) spectrum peak method was implemented. In this method, the ratio between the peak energy of a wave system and the energy of the PM spectrum with the same peak frequency is computed. If this ratio is greater than one, the wave system is categorized as wind-sea; otherwise, as swell. Later, a support vector network (SVM) classificator was applied to significant height (Hs) and peak period (Tp). Results indicate that a linear expression (Tp = 2.5 Hs + 3.3) optimally separates wind-sea and swell. The typical Hs were 1–2 m for wind-sea and 0.5–1 m for swell, with mean Tp values of 5.2 s and 10.5 s respectively. Wind-sea waves predominantly propagated from the E and S, while swell from the SE. Swell seasonality indicated the highest occurrence during the winter months and minimal occurrences during summer. Finally, the performance of the WAVERYS and IOWAGA products in predicting arrival times of swell at the RDP was evaluated. Both predicted an earlier arrival time for swell in over 70 % of the events. These results highlight the reliability of these global products in anticipating swell arrivals.</div></div>","PeriodicalId":21070,"journal":{"name":"Regional Studies in Marine Science","volume":"83 ","pages":"Article 104079"},"PeriodicalIF":2.1,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143453965","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}

The main focus was determining the magnetic properties of sediments from different depositional environments (marine, estuarine and fluvial) and assessing their variation with the provenance. In addition, various factors (catchment rocks, anthropogenic activities, river morphology) that influenced the magnetic signatures were explored. Most rivers showed higher magnetic concentrations in the wet period compared to the dry period. The magnetic concentrations (χ_lf) in the Goa rivers (Terekhol, Chapora, Sal, Talpona) were 6–10 times higher than that of the Karnataka rivers (Nethravati and Gurupur) and displayed a systematic decrease from the river towards the estuary mouth/sea reflecting hydrodynamic sorting. In the Karnataka rivers, on the other hand, irregular χ_lf profiles were attributed to factors such as dredging, river geomorphology, abundant quartz minerals and variations in Estuarine Turbidity Maxima’s locations. Based on magnetic parameters and elemental composition obtained from SEM-EDS analysis and confirmed by XRD results, magnetite was identified as the main magnetic mineral in the Goa rivers, while a mix between magnetite and hematite was proposed in the Karnataka rivers. Anthropogenic activities (sand mining) and local geological background contributed to magnetic enhancement in the Goa rivers, while river morphology (meandering) and hydrodynamic processes controlled the magnetic properties in the Karnataka rivers. The negative correlations between χ_lf and finer sediment fraction, as opposed to other global studies, suggested the possibility of such occurrence in similar systems worldwide. The biplot between magnetic grain size and χ_lf in the Karnataka rivers could fingerprint the source and track the environmental changes. Thus, the magnetic measurements were helpful in the discrimination and identification of different depositional environments.</div></div>","PeriodicalId":21070,"journal":{"name":"Regional Studies in Marine Science","volume":"83 ","pages":"Article 104068"},"PeriodicalIF":2.1,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143453967","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}

However, since the beginning of the 2000s, local coral communities have been in a state of increasing decline resulting from the enhancement of stressful natural and anthropogenic impacts. During the 3-year period (2022–2024), a complex assessment of coral reef status and a number of stressful factors has been performed on 17 reef sites in the coastal waters of the province. The mean coral cover was 27.4 % ± SD 26.8 %; coral taxa with stress-tolerant and weedy life strategies made the largest contributions to the composition of local coral communities. Only 5 of 17 sites revealed relatively high cover (&gt;50 %), and only 7 sites had a coral genus richness &gt; 10.

Five stressful environmental factors stipulating reef decline were distinguished: 1) impact of annual cyclones; 2) anthropogenic reinforcement of sedimentation and eutrophication; 3) overfishing; 4) repetitive crown-of-thorns starfish outbreaks; and 5) sea surface temperature anomalies (the latter is mitigated by seasonal upwelling).
