Summary: According to the Natura 2000 Network, various studies have been conducted to assess the importance of new marine protected areas. One of these studies examines the Capbreton Submarine Canyon System located in the Bay of Biscay. Through surveys and data analysis, researchers were able to characterize the morphosedimentary features of the canyon system and identify the presence of a large pockmark field.

Summary: This study integrates deep learning techniques, high resolution multibeam echosounder data, and species distribution models to identify and map vulnerable marine ecosystems (VMEs) in the Capbreton Canyon System. By using photo-grammetric measurements and a deep learning framework, the localization and identification of the yellow coral were successfully achieved, and a species distribution model revealed its spatial distribution in the study area. The results of this study provide a baseline for the protection of vulnerable habitats in the Capbreton Canyon System.

Summary: The study on the Deba and Urola estuaries reveals significant environmental changes at millennial, centennial, and decadal timescales, primarily influenced by regional driving forces such as fresh-water discharge, relative sea-level variation, and industrial development. These changes include shifts in hydrodynamic structure, salinity, and marine influence in the estuaries at different timescales.

Summary: The study identified spatial variability in soft-bottom macrofaunal communities in the southeastern Cantabrian Sea, with depth, density, and species showing decreasing trends. Greater variability in species assemblages was observed on the continental shelf, but no clear relationship was found with sedimentary characteristics. The most significant depth-related changes occurred around 200-400 meters, coinciding with variations in sediment characteristics.

Summary: The study focused on the abundance, distribution, and status of marine debris on the Thondi coast, Palk Bay, Southeast coast of India. Results showed that plastics were the predominant type of marine debris, with a Clean-Coast Index ranging between 4.25 (clean) and 20.4 (extremely dirty). The high CCI value indicated a significant level of marine debris pollution, mainly from land-based sources. The findings suggest the need for improved waste management and prevention efforts to protect the marine environment.

Summary: This study assessed the interannual variations in copepod densities in the southeastern Bay of Biscay and their relationship to climate teleconnections and local environmental factors. Opposite density patterns were observed between different seasons and species, and they were positively correlated to NAO, EA, water temperature, and chlorophyll a.

Summary: Temporal variations of rare earth elements (REE), major elements, Pb, and Hg were studied in two multicores collected in the Cascais submarine canyon, showing a mixture of Tagus estuarine and marine sediments with patterns influenced by an abandoned chemical complex and preferential diagenetic remobilization of LREE relative to HREE in deeper sites. The influence of diagenetic processes in the REE signal and dispersion of anthropogenic components from the estuary through the canyon were observed.

Summary: This dataset presents the macrobenthic species abundance and biomass in soft bottom areas located at southeastern Bay of Biscay, along with data on organic matter content and grain-size distribution in surficial seafloor sediments. The dataset is useful for research on spatial variability of macrobenthic communities and for establishing baseline knowledge of species in the area. The research article based on these data was published in the journal Regional Studies in Marine Science, focusing on macrofaunal variability in the continental shelf and canyons in the southeastern Bay of Biscay.

Summary: The distribution of heavy metals in seafood intake was studied in the Kalpakkam coastal region. The average concentrations of heavy metals in 40 different fish species were determined. Zinc and copper were found to have higher bioaccumulation index and metal pollution index. Risk assessment calculations showed high values for different age groups. However, the cancer risk did not exceed recommended limits in the region.

Summary: This study investigates the subsidence history of the ancient Zhejiang-Fujian Uplift (ZFU) through the analysis of marine sedimentary layers in the Ningde area of southeast China. The results suggest that the ZFU has experienced rapid subsidence since the last interglacial period (MIS 5e) and has stabilized since the last glacial period (MIS 3). This study provides new insights into the subsidence history of the ancient ZFU and land-sea interaction in the tectonic subsidence region.

Summary: Nepheloid layers with elevated concentrations of suspended particulate matter (SPM) are found globally, resulting from natural and anthropogenic processes. Accurate quantification of SPM mass concentration is essential for assessing material dispersion, but different sensors may lead to varying estimates.

Summary: In the context of the European Marine Strategy Framework Directive, a team of researchers has assessed the marine environmental status of the Basque coastal zone. Overall, the coast is in good status, but specific ecosystem components show areas for improvement. The integrated assessment approach and NEAT software can guide European practitioners in prioritizing management measures.
