Summary: An extremely low salinity anomaly was observed in the Bay of Bengal in spring 2012, caused by the rare co-occurrence of positive Indian Ocean Dipole and La Nina events in 2011, leading to reversing circulation anomalies that inhibited freshwater transport to the southern Bay. The modulation of monsoon by interannual processes played a key role in forming this extreme event, highlighting the importance of oceanic circulation in sea surface salinity variability in the Bay of Bengal.

Summary: This study in early summer in the Ariake Sea found that the distribution of dissolved trace metals and macronutrients is influenced by water circulation and geochemically driven cycles. D-Mn and d-Fe were removed during estuarine mixing, while sedimentary fluxes were identified as the main source of d-Cu. The conservative pattern of d-Co reflected a balance between input and removal during estuarine mixing.

Summary: The distribution of sea surface salinity in the Arabian Sea and Bay of Bengal is influenced by air-sea freshwater fluxes and river runoff inputs. The monsoon-induced inter-basin water exchange is crucial for regional salinity balance and atmosphere-ocean feedback. South of the Indian Peninsula, there is significant intraseasonal variability of sea surface salinity, with the strongest amplitude observed during winter. The Northeast Monsoon Current and mesoscale eddies play a dominant role in this variability.

Summary: Warming and eutrophication pose threats to bay ecosystems, but the impact on zooplankton varies. Xiangshan Bay in the East China Sea is affected by global warming and thermal drainage, making it a suitable location to study zooplankton response to warming in low-salinity areas. The study found a decrease in abundance and biomass of large mesozooplankton in XSB, mainly due to low gelatinization and changes in species composition.

Summary: Internal waves are generated in oceans, especially in regions with highly stratified waters due to the influx of freshwater from nearby rivers. This study focuses on the characteristics of internal tides in the Bay of Bengal and the Andaman Sea using high-resolution salinity estimates and observed data. The analysis reveals the surface imprints of diurnal period internal tides due to the presence of haloclines, while the impact of semi-diurnal period internal tides is suppressed by thermoclines. The wavelengths and phase speeds of these internal tides vary along the study area.

Summary: Changes in sea surface salinity (SSS) caused by freshwater discharge from rivers affect estuarine marine environments. Previous studies have shown that salinity can be estimated using radar technology, but quantitative assessments and long-term validations are lacking. This study used a phased-array high-frequency (HF) radar to estimate SSS in Ise Bay, Japan, over a one-year period. The estimated SSS map was consistent with previous studies, and the root mean square error (RMSE) for radar data compared to in situ observations was determined. The results suggest that HF radar can be a useful tool for monitoring SSS and understanding the physical and environmental effects of river water discharge.

Summary: The distribution of stable isotopes in the Arabian Sea shows significant vertical variability, with 18O-enriched water in the north and 18O-depleted water in the south. However, the entire water column exhibits a strong relationship between stable isotopes and salinity. This difference can be explained by winter monsoon-driven convective mixing and intrusion of low salinity (and low delta 18O) water from the Bay of Bengal in the southern Arabian Sea.

Summary: Based on the analysis of salinity anomalies in the Bay of Bengal, it was found that horizontal advection is the major contributor to the variability in salinity. With the development of La Nina and negative Indian Ocean dipole, the strong summer monsoon current and anomalous basin-scale circulation led to the influx of high-salinity water into the northern Bay of Bengal, while the east Indian coastal current transported more freshwater southward, resulting in extreme negative salinity anomalies around Sri Lanka.

Summary: Modification by sialylated glycans can affect protein functions, underlying mechanisms that control animal development and physiology. The sialylation pathway, involving CSAS and SiaT genes, functions in the nervous system of Drosophila, affecting neural transmission and excitability. CSAS is restricted to glia, while DSiaT functions in neurons, allowing for regulation of neural functions via a glia-mediated control of neural sialylation. The sialylation genes are required for tolerance to heat and oxidative stress and for maintenance of the normal level of voltage-gated sodium channels.

Summary: Human microbiome composition is influenced by the natural host environment, specifically mucus, which contains gel-forming glycoproteins (mucins) with regulatory functions. Mucin glycans enable the coexistence of diverse microbes and prevent disease-associated compositional shifts. Different glycosylation patterns of mucins shape microbial communities by providing nutrients, organizing spatial structure, and potentially limiting competition. This study highlights the importance of mucin glycans as a host mechanism and potential therapeutic approach for maintaining a healthy microbiome.

Summary: This study aimed to assess the explosive muscle performance of the upper body in athletes using various measurement parameters and examine their relationship with athletic performance. The results showed a significant positive correlation between medicine ball throw and athletic performance, while push up jump and countermovement push up were not associated with performance. Additionally, one repetition maximum of the bench press did not show a significant correlation with athletic performance. Athletes are advised to choose events where their weight positively affects their competitive ability and incorporate explosive muscle performance without counter movements in their physical fitness assessment.

Summary: The study focused on heavy metal pollution in the green vegetation of a suburban industrial area in Tuokexun County, Xinjiang, China. The results showed that the overall level of heavy metal pollution in the soil was minor, with mercury (Hg) being the most severe contamination, likely caused by human activities. The composition of heavy metal elements in trees was more stable compared to grass and shrubs, with varying concentrations across different vegetation. Shrubbery was found to be the most effective in heavy metal restoration, and there were disparities in heavy metal enrichment among different vegetation types.

Summary: Plastic pollution has significant environmental impacts, largely due to chemical additives. However, the behavior of plastic additives in marine environments is not well understood. A marine deployment experiment was conducted to investigate the effects of weathering on the extractables profile of four types of plastics in New Zealand over a period of nine months. The concentration of additives in polyethylene and oxo-degradable polyethylene was strongly influenced by artificial weathering, while polyamide 6 and polyethylene terephthalate showed minimal change. These findings emphasize the importance of considering leaching and weathering effects on plastic composition when assessing the potential impact and risk of plastic pollution in receiving environments.

Summary: Few studies have examined the impact of urbanization and meteorological events on microplastics discharged into the sea through rivers. Surface water samples were collected from two Lebanese rivers, with differing degrees of urbanization, during dry and wet periods. The results showed that the most industrialized river had a significantly higher abundance of microplastics compared to the less-industrialized river. There was also a correlation between particle contamination and the season at each site, with microplastic concentrations highest on the first day of the wet season. These findings highlight the importance of considering meteorological events in accurately assessing plastic pollution influx into coastal waters.

Summary: This study investigated the variability in phytoplankton functional structure using a trait-based approach and explored the relationship between species traits and environmental factors, as well as their impact on ecosystem functioning. The results revealed that morphological traits, temperature, and ammonia played a decisive role in the seasonal succession of phytoplankton species. It was found that certain traits favored higher biomass production but might hinder energy transfer efficiency. The strong correlation between environmental variables and phytoplankton functional structure supports the practical implementation of a trait-based approach in studying phytoplankton community dynamics under different environmental conditions.
