Summary: Information on invertebrates in low-flow water bodies of northeastern Siberia is incomplete, with limited knowledge about crustaceans. A study in the Lena River Delta found 59 crustacean species and taxa, including five new to the region, and identified three types of crustacean assemblages characteristic of different stages of tundra lake development. The research confirmed that the formation of crustacean taxocenes in the Lena River Delta is mainly determined by temperature and local features of the water body.

Summary: Oceanic melting beneath ice shelves drives the current mass loss of the Antarctic ice sheet. The meltwater plumes that result from this melting influence the melting of ice shelves and contribute to the development of unique stratified ice shelf-ocean boundary currents. However, there is still much to learn about the dynamics and thermodynamics within these meltwater plumes.

Summary: The distribution of rare earth element (REE) concentrations and Nd isotopic compositions (εNd) in the Rockall Trough of the North-East Atlantic were studied. The results revealed a spatial εNd gradient in the upper layer of the Rockall Trough, with the influence of Nd lithogenic inputs found to be negligible. The study also identified the southward-flowing Wyville-Thompson Ridge Overflow Water (WTOW) originating from the Nordic Seas. These findings contribute to our understanding of North Atlantic gyre dynamics.

Summary: This study presents an evaluation of the downward fluxes and composition of particulate matter in the Beagle Channel. The results show that the fluxes and composition of particulate matter differ between the western and eastern parts of the channel, with the former influenced by glacial and organic material, and the latter dominated by river inputs and phytoplankton blooms. This research contributes to understanding the impact of climate change on the biological carbon pump and land-sea connections in this high-latitude ecosystem.

Summary: This article investigates the evolution of the Sevastopol eddies using altimetry measurements and a high-resolution Nemo numerical model. The eddies can reside in the Black Sea for >3-6 months, impacting cross-shelf exchange and nutrient fluxes. The stationarity of the eddies is mainly due to the continental slope acting as a barrier, preventing cyclonic propagation.

Summary: The Sao Francisco River is an important river in Brazil, crossing the semi-arid region. A series of dams have been built along the river for hydropower, changing the flow significantly. A hydrodynamic model was used to simulate the effects of flow changes on saline intrusion in the estuary. The simulations showed an increase in mixing and decrease in river contribution after the dams were built. The results can be used by management agencies to improve water quality for human consumption.

Summary: Seasonal-scale local forcings reduce coastal pH and aragonite saturation state. The dynamics of carbonate system parameters were investigated in a coral habitat influenced by seasonal current patterns. Both Oaragonite and pH showed seasonal variations, controlled by dissolved inorganic carbon (DIC) and temperature. Ocean acidification scenarios projected a decrease in Oaragonite amplitude and an increase in hydrogen ion concentration ([H+]) amplitude.

Summary: The Vistula Lagoon, one of the two lagoons on the Polish coast, is economically and environmentally significant. This study aims to calculate the water balance of the lagoon before and after the construction of a canal through the Vistula Spit. The construction of the new connection may impact the lagoon's water balance and its biotic and abiotic environment. Data on precipitation, evaporation, inflow from the catchment, and inflow/outflow through the Strait of Baltiysk were collected for mathematical modeling. The study suggests that the construction of the new canal will not significantly alter the lagoon's water balance but may cause environmental problems.

Summary: We demonstrate that wind-driven Ekman transport enhances the advection and mixing of cells, leading to the transport of colder water from the Surface Antarctic Waters to the warmer waters of the northern Polar Front belt. This mechanism provides cells with a favorable temperature environment, allowing for specific species and community growth rates to develop blooms under non-light limiting macronutrients and iron conditions. Our findings have important implications for increased productivity in a future warming climate.
