Summary: Human intervention has caused significant changes to the southeastern coastline of Bangladesh, where the longest natural sea beach Cox's Bazar is located. Over the past 30 years, nature-dependent livelihood and economic activities have provided employment and income, but have also increased exposure and vulnerability to projected climate-induced natural disasters. The changing land-use pattern due to human intervention can be clearly seen through satellite imageries. Fishing, salt-shrimp farming, fish drying, agriculture, tourism, and small trading are now the main economic activities, with human settlement expansion altering the coastal ecosystem. Salt-shrimp farming and hotel and restaurant industries are the most vulnerable to natural and anthropogenic threats, respectively.

Summary: Plankton are important indicators of ecosystem health as they form the base of marine food webs. This study analyzed plankton datasets from the North-East Atlantic and North-West European shelf to track abundance trends over 60 years. The results showed a decrease in most planktonic lifeforms, except for meroplankton which increased. These trends differed between shelf and oceanic regions, with the North Sea experiencing increasing coastal abundance while the North-East Atlantic showed decreasing abundance. The decline of key planktonic lifeforms in the North-East Atlantic, such as diatoms and copepods, raises concerns for the future of food webs and highlights the need for sustainable management measures.

Summary: This study reviews the current state of physical, chemical, and biological systems in the Barents Sea and highlights the significant changes observed in recent decades. The changes have implications for both the environment and human activities in the region. However, there are still gaps in observation and knowledge, particularly during the winter months, which require further research and development.

Summary: This study investigates the wave climate in the central Beaufort Sea coast and finds a significant correlation between the reduction in sea ice concentration and the increase in average and extreme wave conditions. The extended open-water season leads to a significant increase in wave power.

Summary: The two end-to-end ecosystem models, NORWECOM.E2E and NoBa Atlantis, were used to explore indicators from the Barents Sea Management plans, showing that the selected indicators give a good overview of the ecosystem state but lack of connection between indicators and management actions. The absence of socio-economic and economic indicators is identified as a limitation and the inclusion of these in future management plans is recommended. The evaluated indicators perform well in assessing the ecosystem, but their consistency and representativeness are highly dependent on the time and location of sampling.

Summary: The eastern North Pacific right whale (NPRW), the most endangered population of whale, has been observed north of its core feeding ground with low sea ice extent. Sea ice and water temperature are important drivers for zooplankton dynamics. The study suggests that the whales and their prey C. glacialis may move northward due to the continued loss of sea ice and warming.

Summary: The unique ecosystem services provided by oceans have been impacted by human activities, especially in coastal waters, affecting human well-being. The study focused on China's Yellow Sea and found a significant increase in ecosystem service values between 2000 and 2010, with a decrease in the proportion of food production and an increase in coastal tourism services. Changes in the ecosystem service composition in the Yellow Sea may be related to the reduction of biodiversity and wetland area.

Summary: Recent studies indicate changes in the light climate of the North Sea, with water clarity reducing over the twentieth century and likely continuing. Inorganic sediment is identified as a driving factor in these changes, impacting water clarity and phytoplankton biomass in areas with high nutrient availability.

Summary: Investigating the Goliath slide complex, one of the largest documented slide scars on the continental slope offshore Israel, can provide insights into the history and environmental control factors of submarine slides. The study reveals the timing and potential triggers of prominent slide events in the area, emphasizing the significance of climate and seismic activities in slope instability.

Summary: Lemon sole, a commercially valuable flatfish species in the northeast Atlantic, is believed to spawn between May and October with a peak between May and August. Analysis of lemon sole larvae in the northern North Sea suggests that spawning may continue into late October and November, with overwintering larvae in various developmental stages. Drift modelling indicates that historically documented spawning grounds in the northern North Sea are the source of larvae sampled during surveys in 2016-2017.

Summary: This study examined the occurrence of petroleum waxes in marine surface water in the North Sea, particularly focusing on persistent floaters of small size (<5 mm). Using ATR-FTIR and gas chromatography, the study detected paraffin particles in samples and provided details on their chemical composition. The study highlights the importance of harmonized detection methods for PW pollution and emphasizes the need for consistent monitoring systems in conjunction with microplastics monitoring.

Summary: In recent years, the frequency of tropical cyclones in the Arabian Sea has increased, showing significant trends in intensity, frequency, and duration, while the Bay of Bengal has experienced a decrease in both frequency and duration. This increase in tropical cyclone activity over the Arabian Sea is associated with changes in environmental factors such as sea surface temperatures and steering currents.
