Summary: This study analyzed sinking particles in the Gotland Basin of the Baltic Sea from samples collected in a sediment trap. The research aimed to examine the temporal variability of particle flux and its components, and its correlation with phytoplankton blooms. Variables studied included total particle flux, organic carbon, nitrogen, biogenic silica, C:N ratio, and isotopic composition of organic carbon and nitrogen. The findings showed variability in the sinking material, with peak flux occurring during phytoplankton blooms. The study highlights the importance of continued monitoring to understand the impacts of environmental changes on this fragile ecosystem.

Summary: The study found that Major Baltic Inflows have a limited impact on the water column P inventory and eutrophication level of the Gotland Basin, as insufficient Fe availability prevents efficient trapping of phosphate. The fast recovery of reducing conditions only allows short-term storage of Mn-Fe-P mineral phases in the surface sediment. Trace metals such as V and W show intermittent depletion in the water column, but are released back into the water column due to re-establishing reducing conditions.

Summary: The Baltic Basin is famous for its Paleozoic hydrocarbon reservoirs. This study investigated the hydrocarbon migration pathways and escape structures from Paleozoic source rocks to the seafloor using multibeam, sediment sub-bottom profiler, and seismic reflection data. The results identified a hydrocarbon migration system in Silurian and Devonian strata, with migration occurring beneath sealing layers, along faults, and through seafloor escape structures. The migration trend was directed updip towards the Gotland Depression. The study also highlighted the importance of the regional geological setting and iceberg scouring in facilitating hydrocarbon migration.

Summary: The marine-terrestrial Baltic ecosystem is sensitive to environmental changes, with research showing a time delay in sediment records between the Western Gotland Basin and Lake Tiefer See during the Mid-Holocene climate oscillation. The delay is likely due to increased freshwater input during the early stages of the oscillation, resulting in strengthened stratification in the marine environment.

Summary: Thermohaline intrusions were observed in the Baltic Sea, with extremely cold and salty waters suggesting possible formation in the Arkona/Bornholm basins. Factors driving the intrusions in April 2013 included easterly winds and seasonal solar heating, contributing to the beginning of the Cold Intermediate Layer formation. The transition to a three-layered summer water structure in the Baltic Sea is influenced by sea-scale exchange processes and vertical mixing prolonged by climate warming.

Summary: The vertical thermohaline structure in the southeast part of the Baltic Sea is complicated, with two layers of salinity field and seasonal changes in water temperature stratification. This study compared CMEMS reanalysis data with independent field data and found overestimated water salinity within the Cold Intermediate Layer (CIL) and the halocline, along with a shallower upper boundary for the CIL in the reanalysis data compared to the field data. However, the general structure of the CIL is well reproduced by the reanalysis data.

Summary: The dataset contains information on spectroscopically verified microplastics, both particles and fibers, from 44 marine surface water samples in the Gulf of Riga and the Eastern Gotland Basin, two sub-basins of the Baltic Sea. The sampling process involved the use of a Manta trawl with a mesh size of 300 μm. The collected samples were then digested and analyzed using various methods to determine the shape, size, color, and polymer type of each item, providing valuable data for studying microplastic pollution and calculating microplastic flow.

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.

Summary: This study aimed to gain a better understanding of the role of dissolved organic matter (DOM) in the biogeochemistry of the Southern Patagonian shelf. The results showed that terrigenous input is the main source of ammonium and refractory carbon in the region, while the Antarctic Circumpolar Current contributes autochthonous DOM. Additionally, regeneration processes of nitrogen-rich water were found in the Tierra del Fuego Waters and Grande Bay regions.
