Summary: The study explores the spatial structure of Barents Sea ice change over the past 40 years, finding that the dominant mode of winter sea ice concentration variability is related to areal change. This mode is influenced by the temperate Atlantic inflow and sea ice import, and is also affected by anomalous wind and sea ice area import. Basic predictability is mainly associated with the areal-change mode, influenced by the temperature of the Atlantic inflow and sea ice import from the Arctic.

Summary: The Polar Front in the Southern Ocean is a significant factor in global ocean circulation and impacts biogeochemistry and sea-air interaction. A study of the region in 2018 revealed an unusually strong spring bloom, potentially due to upwelling bringing nutrients and dissolved iron. This led to changes in the phytoplankton community and an increase in carbon sink activity.

Summary: Climate change-induced loss of Arctic sea ice is predicted to have negative impacts on genetic diversity and gene flow in ice-dependent species like polar bears. A study on polar bears in the Svalbard Archipelago showed a loss in genetic diversity and an increase in genetic differentiation, attributed to habitat fragmentation caused by reduced sea ice coverage leading to increased inbreeding within local populations. This highlights the importance of genetic monitoring for developing adaptive management strategies for polar bears and other ice-dependent species.

Summary: Significant research has been conducted in the Chukchi Sea during the summer months, but there is a lack of data for other seasons. Different zooplankton communities have been identified in the northeastern Chukchi Sea, each associated with specific water masses and seasonal conditions. The populations of key copepod species Calanus glacialis in the Chukchi Sea are replenished annually from the northern Bering Sea due to the shorter flushing time of the Chukchi Sea compared to the copepod's generation time.

Summary: Understanding the intraseasonal variations of Arctic sea ice is crucial for predicting climate variations and trans-Arctic shipping. This study found that the dominant periodicity of sea ice change in the Northern Barents Sea during summer is 30-60 days, modulated by circumpolar clockwise-propagating atmospheric waves. These atmospheric waves induce meridional thermal advection, modulating surface temperature and atmospheric moisture, causing changes in sensible heat and longwave radiative fluxes, and ultimately regulating the sea ice variations. The mechanism highlights the importance of accurately predicting atmospheric fields for more accurate sea ice subseasonal prediction.

Summary: This study focuses on the Pechora River plume in the southeastern part of the Barents Sea and finds that many aspects of its structure and variability are still unknown. By analyzing extensive in situ measurements and satellite observations, the study reveals the dependence of the plume's characteristics on wind forcing, river discharge rate, and spring ice conditions. The results show regular advection of the plume into the Kara Sea and the formation of a significant area of increased salinity during wind-induced coastal upwelling events. This research is important for understanding the physical, biological, and geochemical processes in the Pechora Sea and adjacent areas.

Summary: The study identified a transport barrier near the Norwegian islands that restricts the exchange of C. finmarchicus populations between shelf and oceanic waters. As mesoscale eddies increase in the mid- to late April, the transport barrier is broken down, leading to off-shelf transport of C. finmarchicus.

Summary: Recent observations in the Arctic have challenged the previous belief that marine ecosystems in polar areas are mostly inactive during the polar night. The presence of Calanus finmarchicus in the upper part of the water column in early January, contrary to its predicted behavior, has prompted further investigation into the underlying mechanisms and potential impacts. This study found a close relationship between the abundance of C. finmarchicus in surface waters and Polar Surface Water near the sea ice edge, suggesting the importance of lipid-rich copepods in driving the spatial distributions of top predators in the Arctic.

Summary: Vertical behavior, such as diel vertical migration (DVM) and swarming, is widespread among zooplankton. In the Norwegian Sea, synchronized DVM and large near-surface swarms were observed in the zooplankton community. The zooplankton community was concentrated in the upper 20 meters in calm weather but retreated to greater depths in the presence of increased near-surface turbulence, indicating synchronized schooling behavior.

Summary: The strong mesoscale eddy activity in the northern Norwegian Sea has a significant impact on the phytoplankton biomass levels. Eddies induce negative or positive chlorophyll-a concentration anomalies through horizontal and vertical transport-mixing. Wind-eddy interactions also result in positive or negative chlorophyll-a concentration anomalies. Eddy-induced Ekman upwelling plays a key role in the positive chlorophyll-a concentration anomalies within anticyclonic eddies (ACEs), promoting nutrient transport and phytoplankton growth. The combined effects of wind-eddy interactions and seasonal shallowing of the mixed layer depth contribute to the large chlorophyll-a concentration anomalies in May and June.

Summary: The limited ecological data hinder our understanding and prediction of the impact of human activities on pelagic marine ecosystems. Isoscapes, spatial models of stable isotope ratios, have been used to study biogeochemical processes and ecological responses. In this study, isoscape models were developed for the North Atlantic Ocean using archived samples from plankton surveys. These models provide valuable insights into marine predator ecology and can improve conservation efforts in the future.

Summary: Zooplankton and ichthyoplankton in oceans can be detected as horizontal sound scattering layers (SSLs). However, quantifying their composition and density is subject to sampling biases. This study used autonomous hydroacoustic surveys and trawl sampling to investigate the epipelagic fauna in northern Norway. The inverse method applied to autonomous acoustic surveys can improve density estimates by diminishing avoidance biases and increasing the spatio-temporal resolution of ship-based surveys.

Summary: This study uses standardized ocean color imagery and radiative transfer modeling to identify reflectance anomalies potentially caused by surface swarms of Calanus finmarchicus in the northern Norwegian Sea. The results show high anomaly within the 'red' patch, indicating the presence of something other than the standard bio-optical model constituents. Optical closure is achieved through the addition of C. finmarchicus absorption into the model. The analysis suggests the potential for the over-estimation of chlorophyll concentrations if C. finmarchicus populations are present in the surface waters.

Summary: Coloration in copepods, caused by the accumulation of carotenoid pigments, is a widespread trait in freshwater and marine ecosystems. This pigment variation is influenced by multiple factors such as diet, temperature, UV radiation, predation, metabolism, and reproduction. The role of pigmentation in copepod fitness is due to its antioxidant power and metabolism, and the potential camouflage strategies it provides. Further research is needed to understand the molecular mechanisms and ecological implications of copepod pigmentation.

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.

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.
