Summary: This study evaluated the effect of tides on the behavior of three major rivers in the eastern shelf seas of China. The results showed that tides induced dispersed transport for some rivers and concentrated transport for others. Tides dramatically slowed the river water transport and export rate, leading to increased water concentration and decreased seawater salinity. The study highlights the importance of including tidal effects in earth system models for accurate projections.

Summary: The study investigates the ocean response to wintertime sea ice retreat in the Nordic seas using the HiGEM climate model. It finds that under global warming, the impact of ocean response differs from that caused by sea ice retreat, leading to changes in water column mixing, temperature, and salinity.

Summary: This study discusses the transport of heat and salt through the Nordic Seas based on a regional, high-resolution coupled sea ice-ocean numerical model and climatological data. The analysis shows that warm, salty water is exported from the Norwegian Sea into the Greenland and Iceland Seas, with the mean cyclonic boundary current system and eddy fluxes playing important roles in this exchange.

Summary: The strength of the AMOC at subpolar latitudes is dominated by water mass transformation in the eastern SPNA. However, the distribution of this overturning across the individual circulation pathways of both the SPG and the Nordic seas overflows is poorly understood. Water mass transformation along the pathways of the eastern SPG accounts for 55% of the mean strength of the eastern subpolar AMOC.

Summary: Water mass transformation and overflow of dense waters across the Greenland-Scotland Ridge play a crucial role in maintaining the Atlantic meridional overturning circulation. The variability in Nordic Seas overturning circulation between 1950 and 2020 is found to be related to surface buoyancy forcing in the eastern Nordic Seas. The multidecadal variability in the Nordic Seas overturning circulation is in phase with the Atlantic Multidecadal Variability index, but there is no long-term trend.

Summary: Idealized numerical models and theory are used to study the circulation and exchange between marginal seas and the open ocean that are influenced by periodic winds. Two distinct regimes are identified: an interior closed circulation system and a shallow shelf region that connects to the open ocean. The dynamics are controlled by the bottom Ekman layer and interior ageostrophic flows in the interior, and by the frictional decay of coastal waves on the shelf.

Summary: The sources and burial processes of marine organic carbon (OC) in the eastern China marginal seas (ECMS) were studied using marine lipid biomarkers. It was found that sediment grain size is a key factor in the preservation of marine OC and biomarkers. The proto-burial efficiency of marine OC in ECMS was higher than in other marginal seas.

Summary: This study focuses on the intraseasonal sea ice loss events in the North Barents-Kara Seas during boreal winter in the Arctic. The contributions of latent and sensible energy sources to downward longwave radiation (DLW) and sea ice reduction are quantified, and the sources of these energy forms are examined. The study reveals that both latent and sensible energy sources play a significant role in DLW increase and explain a considerable portion of the sea ice reduction. Geographically, the North Atlantic, the Norwegian, North, and Baltic Seas, western Europe, and the northeastern Pacific are major atmospheric energy source regions.

Summary: The study focused on wind-driven exchange between marginal seas and open oceans, finding strong baroclinic flows along island boundaries with maximum transport in gaps. Topography around islands alters current pathways but cannot ultimately limit total wind-driven exchange.

Summary: The vertical structure of Arctic warming plays a crucial role in understanding its impact on midlatitudes. Deep Arctic warming events are closely related to Eurasian cooling, while shallow Arctic warming events have weaker correlation with Eurasian cooling.

Summary: The study shows that the inflow across the Iceland-Scotland Ridge impacts the heat supply to the Nordic seas from the subpolar North Atlantic and influences marine ecosystems and sea ice extent further north. The inflow primarily originates from the subtropics and the Arctic, with its properties and volume transport being affected by atmospheric circulation anomalies and shifts in ocean currents. Gyre dynamics and wind forcing play a crucial role in determining the inflow properties and volume transport in the Nordic seas.

Summary: Changes in ocean circulation play a crucial role in centennial-to-millennial scale climate variability during the last deglaciation. Through sediment records from the Nordic Seas, researchers studied radiocarbon ventilation ages to reconstruct past variations in watermass overturning. Variability in ventilation ages among different records suggest regional shifts in deep convection and emphasize the importance of using uniform material for reconstructing bottom water ventilation histories.

Summary: Research on sedimentary organic carbon (SOC) in eastern China marginal seas revealed that SOC mainly originates from indigenous production and is buried in the South Yellow Sea mud area (SYSMA) and East China Sea mud area (ECSMA). While ECSMA has a higher net particulate organic carbon deposition flux, the SOC burial efficiencies in both areas are similar.

Summary: The microbial cycling of DMSP and resulting gaseous catabolites DMS or MeSH is important for the global sulfur cycle and climate regulation. The sea surface microlayer (SML) is crucial for the generation and emission of DMS and MeSH. This study investigates the differences in DMS/DMSP, bacterial community structure, and key bacterial DMSP metabolic genes between SML and subsurface seawater (SSW) samples in the eastern China marginal seas. The results showed significant spatiotemporal differences in DMSP synthesis and degradation in the SML, with higher activity compared to SSW.
