Offshore solar is a new renewable energy technology currently developing in the Netherlands, with the first offshore tests of four years at rough conditions being successfully completed. Submerged parts of offshore renewable energy devices get fully colonised by fouling organisms, which take advantage of the new artificial habitats. In this study, we conducted an exploration of the fouling fauna that colonised the floaters of a solar farm installed for the first time in offshore waters in the Netherlands. The biofouling attached to the underwater parts of 18 floaters forming 3 clusters were sampled in a quantitative way by scuba divers. Macrofauna species and biomass were quantified in all samples. In total, 47 different taxa, including 12 non-indigenous species, were identified to occur on the floaters. Arthropoda (mainly individuals of the genus <em>Jassa</em>) was the most abundant phylum, while Mollusca (mainly blue mussel <em>Mytilus edulis</em>) showed the largest biomass. No significant differences in abundance nor biomass were observed between the two months of installation. Non-indigenous species were more abundant in number but contributed less to the total biomass compared to native species on the examined floaters, regardless of the month they were installed. The findings of this study suggest that, like any offshore artificial structure, offshore solar farms could act as stepping-stones for the spread of species. However, long-term monitoring is needed to confirm these results and gain a more comprehensive understanding of the development of fouling fauna on offshore solar farms.</div></div>","PeriodicalId":50056,"journal":{"name":"Journal of Sea Research","volume":"208 ","pages":"Article 102627"},"PeriodicalIF":2.9,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145050277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydrothermal vents are key areas for thermo-chemical exchanges between the lithosphere and hydrosphere and host unique biodiversity. Since 2010, the EMSO-Azores observatory has maintained arrays of multidisciplinary sensors at the Lucky Strike Hydrothermal Field (LSHF; 1700 m water depth), on the slow spreading mid-Atlantic ridge. This infrastructure, combined with repeated yearly sampling during the MoMARSAT maintenance cruises, aims at understanding the feedbacks between tectonics, volcanism and hydrothermal circulation, the coupling between these processes and the hydrothermal ecosystem, and their impacts on the water column. In this review, we summarize 15 years of integrated and multidisciplinary study at LSHF and discuss the societal relevance of this observatory. Hydrothermal circulation is strongly constrained by crust permeability and the availability of magmatic heat. Its variability accounts for the spatial heterogeneity of chemical fluxes and biological communities observed. Tidal modulation of seafloor pressure and near seafloor currents impact venting temperatures, species behaviour, and their physiology. Tidal currents also influence plume dynamics and facilitate particle export to the ocean. At pluri-annual scales, geological events (faulting, seismicity, and magmatic replenishment) have led to changes in fluid chemistry, impacting local microbial communities. However, results obtained over the 15 years of monitoring point to a relative stability of the overall vent system, challenging the idea that hydrothermal vents communities are highly dynamic and ephemeral habitats at decadal timescales.</div></div>","PeriodicalId":50056,"journal":{"name":"Journal of Sea Research","volume":"207 ","pages":"Article 102625"},"PeriodicalIF":2.9,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145026706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined this teleconnection comprehensively, utilizing observational data from multiple sources, and proposed a physical mechanism involving SPMM-ITCZ (Intertropical Convergence Zone)-WPSH (western Pacific subtropical high) variabilities. The weakened ITCZ associated with a positive SPMM resulted in a weakened sinking branch to the north, consequently increasing convection and precipitation in the western Pacific (150–180°E; 9–27°N). This weakened the WPSH by stimulating a cyclonic anomaly, which promoted moisture transport and precipitation on the eastern edge, establishing positive feedback. At the western edge of this cyclonic anomaly, strong northerly wind anomalies reduced moisture replenishment and caused descending anomalies over the eastern part of BYECS. High-pressure anomalies on the western side of the northerly wind anomalies also resulted in descending anomalies over the BYECS. The inhibited upward motion and moisture replenishment jointly led to reduced cloud cover and increased shortwave radiation, thereby increasing BYECS sea surface temperature anomalies (SSTa) alongside SPMM-SSTa.

This study shows an advanced predictive pipeline that uses satellite remote sensing data with ensemble Artificial intelligence (AI) modeling to forecast HAB events along the coastlines of Bandar Abbas, Qeshm, and Hormuz. Key environmental variables, including chlorophyll-a concentration, sea surface temperature (SST), and remote sensing reflectance (R_rs) at wavelengths of 412, 443, 488, 513, and 555 nm, were extracted from MODIS-Aqua imagery, providing a comprehensive depiction of the spatial and temporal variability in the marine environment. We employed a species distribution modeling approach that integrates an ensemble of five machine learning (ML) algorithms—Random Forest (RF), Boosted Regression Trees (BRT), Support Vector Machines (SVM), Multi-Layer Perceptron (MLP), and Radial Basis Function (RBF)—to mitigate the limitations of single-model predictions and enhance forecast reliability. Our modeling framework utilized 1809 confirmed HAB presence observations alongside 13,396 systematically generated pseudo-absence points, with model performance validated through bootstrapping and cross-validation over 713 daily prediction intervals. The ensemble model, formulated via AUC-weighted aggregation of individual predictions, achieved a robust average Area Under the Curve (AUC) of 0.95 and a peak True Skill Statistic (TSS) of 0.85. Specifically, a case study on November 23, 2008, yielded a sensitivity of 96.67 % and specificity of 74.37 %, highlighting the model's proficiency in correctly identifying HAB events. Variable importance plots pinned SST and certain Rrs bands (particularly at 443 and 555 nm) as key predictors, which concurs with established drivers of algal growth. Further, this coupled method not only yields high-resolution spatial and temporal forecasts of bloom events but also refined insight into environmental mechanisms underlying HAB dynamics, informing effective coastal governance and policy making.

During January to March 2023 (dry season), macrobenthic fauna, comprising various groups with distinct ecological traits, were collected in the rocky intertidal zones. Environmental gradients were derived from long-term salinity, temperature, depth, and dissolved oxygen (DO) records from the Pearl River Estuary ecosystem field station, field measurements of anthropogenic disturbance, and GIS-calculated isolation distances. Island areas were obtained from the Guangdong Province Department of Natural Resources. The findings revealed that the species richness of the total, Molluscs and Annelids fit the power-function species–area relationship, whereas Arthropods did not. The generalized linear models showed a significant negative correlation between anthropogenic disturbances and Arthropod richness. Principal coordination analysis and beta diversity indicated substantial dissimilarities in the spatial structure similarity of communities among islands in this area. The analysis of generalized dissimilarity modeling indicated both environmental gradients and spatial distance could affect the β diversity of macrobenthic fauna. In the upper tidal zone, β diversity was predominantly influenced by geographic distance, while in the middle and lower zones, community composition was shaped by the salinity gradient. The outcomes of this study supports the role of area and spatial isolation in structuring community composition and diversity.

We quantify long-term trends, detect structural accelerations, and identify regions of extreme and stable carbonate conditions based on pH, aragonite saturation (Ωₐᵣ), and calcite saturation (Ω_ca). Piecewise regression analysis reveals significant accelerations in the decline of all three parameters, with breakpoints in the late 1990s (Ωₐᵣ, Ω_ca) and post-2009 (pH). Spatial trend and <em>Z</em>-score analyses (Z ≤ −2.0) indicate that the Coral Triangle and adjacent Indo-Pacific regions have experienced the most intense acidification exposure, both in trend magnitude and extreme event frequency. Concurrently, we identify chemically stable zones, defined by Ωₐᵣ ≥ 3.0 and Ω_ca ≥ 1.5, that persist in approximately 12 % of tropical ocean surface waters from 2015 to 2022. Critically, these stable zones show substantial overlap with major coral reef provinces, yet protection gaps remain.
