It has been proposed that mangroves survived in flat microsites beyond the shelf break and later expanded from these microrefugia to their current distribution after the LGM. However, this hypothesis remains untested. This study aims to identify potential refugia by locating flat areas around the −132 m isobath using Global Multiresolution Topography (GMRT) images. A significant ∼200-km-long potential refugium was identified on the northern Trinidad (NT) shelf, along with several scattered kilometer-scale microrefugia near the Cariaco Basin (CB) in northeastern Venezuela. Additionally, two isolated prospective microrefugia were detected in northern Colombia (NC) and western Hispaniola (WH). The remaining LGM Caribbean coasts were considered unsuitable for mangrove growth. The NT refugium, along with the CB microrefugia, may have served as the primary sources for subsequent mangrove expansion. This expansion was likely facilitated by postglacial sea-level rise and the SE-NE Caribbean Current (CC), which would have acted as a major agent for propagule dispersal. This microtopographical survey not only supports the microrefugial hypothesis but also narrows the focus to the most promising areas, significantly reducing the time, effort and resources required for future seismic and coring campaigns.</div></div>","PeriodicalId":50497,"journal":{"name":"Estuarine Coastal and Shelf Science","volume":"323 ","pages":"Article 109404"},"PeriodicalIF":2.6,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144322922","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}

Although studies on phytoplankton communities in this region dates back to the 1960’, this dataset represent the first systematic and regular observations. Over this period, two years - 2014 and 2022 – stood due to their distinctive climatic conditions: extreme rainfall (2014) and severe drought (2022). According to the Intergovernmental Panel on Climate Change (IPCC), such events are expected to become more frequent and intense in the future. Therefore, we also analysed phytoplankton changes during these two years, to explore the potential impact of extreme weather events on phytoplankton dynamics in this coastal area. The prevalent phytoplankton seasonal cycle is bimodal, with a growing season that starts in late winter and continues until early summer, followed by a decline in summer, and a second growth pulse in early autumn. Diatoms and undetermined nanoflagellates dominate throughout the year. Various taxa of dinoflagellates taxa are present in summer, though in low abundances, while coccolithophores (i.e. calcified Prymnesiophyceae) are present in winter. Despite significant variability in abiotic factors, this seasonal and taxonomic pattern remains a consistent feature of the phytoplankton community highlighting the overall variability of the LTER site as well as its similarities with other areas of the Northern Adriatic Sea. The study also suggests potential shifts in phytoplankton patterns in response to extreme weather events, indicating a trend toward more oligotrophic conditions during droughts and increased brackish water influence under most rainy scenarios.

Vegetation self-organization shapes elevation patterns, with dense vegetation promoting accretion and creek-edge zones remaining erosion-prone. Under moderate conditions, marsh zonation remains stable, but extreme scenarios lead to fragmentation and irreversible shifts.

Establishing a favorable environment for developing mangrove tidal flats in estuaries with high wave activity requires targeted wave dissipation and beach stabilization measures. This study focuses on the restoration of mangrove tidal flats in the Huangmaohai Sea (HMHS), located on the western coast of the Pearl River Estuary (PRE), China. To dissipation wave impacts and enhance tidal flat stability, various combinations of bamboo rafts, artificial reefs, pine piles, and ecological oyster reefs were evaluated. Using cross-sectional experiments utilizing a physical model simulating wave dynamics and sediment transport, this study analyzes erosion and deposition patterns affecting mangrove seedlings under different wave recurrence intervals. The results indicate that under a 5 yr recurrence interval, the combinations of bamboo poles with artificial reefs and pine piles with ecological oyster reefs exhibit significant anti-erosion effects. Minor erosion was observed within the initial 1–2 m of the restored beach surface, with a maximum erosion depth of approximately 0.21 m. In contrast, the combination of pine piles and bamboo rows experienced more extensive erosion, with a maximum reach of 17.5 m and an erosion depth of 0.65 m. Erosion patterns under 30 and 50 yr recurrence intervals were also analyzed. The beach surface within the mangrove restoration area exhibits significant erosion, impairing its ability to maintain its original condition. A comparative analysis of the impact of varying bamboo row configurations on soil erosion and deposition in mangrove planting areas reveals that protection is afforded by both the bamboo rows themselves and the planted mangroves within a distance of up to 5 m from the rows. However, this protective effect diminishes with increasing distance. These findings provide a scientific foundation for the protection, restoration, and sustainable management of mangrove tidal flats in high wave areas.</div></div>","PeriodicalId":50497,"journal":{"name":"Estuarine Coastal and Shelf Science","volume":"323 ","pages":"Article 109386"},"PeriodicalIF":2.6,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144313611","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}

The presence of volatile mercury, which has a tropospheric half-life of several months, makes it persist in the atmosphere long enough to be transported long distances polluting the polar regions. Runoff from melting glaciers and geological weathering of the bedrock also have a significant impact on mercury concentrations in the region. Glacier-fed rivers reach the studied fjords, transporting pollutants from these sources, and the Norwegian Sea is a marginal sea. The purpose of this study was to determine the processes and transformations of mercury fractions in sediment cores from Spitsbergen fjords. Eleven bottom sediment cores collected in Kongsfjorden and Hornsund fjords were studied. The sediment samples were analysed by thermodesorption using a DMA-80 direct mercury analyzer (Milestone). Analysis of the processes in the sediment cores and the percentage of the Hg fraction makes it possible to determine the fate of mercury in the Arctic environment. An important feature of the mercury speciation profiles at all stations studied is the dominance of stable fractions. Both diagenesis processes occurring in the sediments involving the transformation of labile fractions into stable fractions and the direct delivery of these fractions to the bottom sediments are responsible for this. The location of the station, including its distance from the glaciers, as well as its depth, was an important factor determining the concentration and proportion of mercury fractions in bottom sediments in the study area. Understanding the fate of mercury in the Arctic environment helps identify its sources and predict further changes, which are strongly influenced by the changing climate. The conducted study indicates that the process of melting glaciers, as a secondary source of pollutants, increases its importance in supplying them to the marine environment.</div></div>","PeriodicalId":50497,"journal":{"name":"Estuarine Coastal and Shelf Science","volume":"323 ","pages":"Article 109394"},"PeriodicalIF":2.6,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144313612","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}
