The location, effort, number of captures, and time of fishing were all used in this study to assess the geographic distribution of in the Taiwan Strait. Other species distribution models performed worse than generalized linear models (GLMs) based on six oceanographic parameters. The sea surface temperature (SST) was between 26.5 °C and 29.5 °C, the sea surface chlorophyll (SSC) level was between 0.3-0.44 mg/m, the sea surface salinity (SSS) was between 33.4 °C and 34.4 °C, the mixed layer depth was between 10 °C and 14 °C, the sea surface height was between 0.57 °C and 0.77 °C, and the eddy kinetic energy (EKE) was between 0.603 °C. According to the statistical findings, SST is merely a small effect compared to SSS, SSC level, and EKE in terms of impacting species distribution. By combining four effective single-algorithm models with no obvious bias, an ensemble habitat model was created. The ranges of 117°E-119°E and 22°N-24°N have the highest annual distributions of S.CPUE and nominal CPUE.

The Great Rann of Kachchh is a sabkha terrain with a thick succession of Quaternary to Late Holocene sediments, deposited during high sea level after the Last Glacial Maxima. Geomorphologically, the Great Rann of Kachchh is subdivided into Bet Zone, Linear Trench Zone, Great Barren Zone, and Banni Plain. The Bet zone is a slightly elevated flat surface comprising a complex network of bets and interbet channels-the geomorphic entities developed as complex interplay of sea level and coseismic tectonic activity during the Holocene.

As the intersection of river, sea, and land, river deltas are hotspots for the accumulation of microplastics (MPs). This study investigated the abundance and characteristics of MPs in surface sediments from shoreline area of the Yellow River Delta in northern China, elucidated their sources, and assessed their risk. The MPs isolated from sediment samples were detected and characterized using optical microscopy and micro-Fourier transform infrared spectroscopy (μ-FTIR).

Anthropogenic pressures affect large stretches of Mediterranean coastal environments, determining alterations, including chemical pollution, able to impair ecosystem functioning and services. Among the pollutants of major concern for their toxicity and persistence, there are polycyclic aromatic hydrocarbons (PAHs), which can be effectively monitored through bioaccumulation approaches. However, the main biomonitor of PAHs in the Mediterranean Sea, Posidonia oceanica, is currently undergoing extensive regressions due to anthropogenic pressures, forcing the search for alternative biomonitors.

We investigate the spatial distribution and potential ecological impact of Currently Used Organophosphorus Pollutants (CUOPPs) in the Arctic Ocean, focusing on the East Siberian Sea, Laptev Sea, and high Arctic regions. Analyzing surface water samples collected during a scientific expedition aboard the "Xuelong 2" in August and September 2021, we detected 38 out of 83 targeted CUOPPs, including Phorate, Paraoxon, and Azinphos-ethyl, with concentrations exhibiting significant geographical variance. The results reveal a pronounced increase in CUOPP concentrations towards the Arctic poles, diverging markedly from the patterns observed in the East China Sea, thereby highlighting distinct regional pollution profiles and environmental interactions.

With the phase-out of legacy persistent organic pollutants (POPs), the ocean's role is evolving, potentially acting as both a reservoir and a source. This study investigates the air-sea fluxes of the first banned POPs, such as organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), using literature from Web of Science up to 2023. OCP and PCB concentrations in air and seawater show significant spatiotemporal variability.
