Summary: The decline in Arctic sea ice has resulted in a loss of habitat for sea ice algae. Compound-specific isotope analysis can be used to trace the origins of elements in marine food webs and identify differences in amino acid patterns between sea ice and pelagic algae. These differences can help estimate the contributions of sea ice and pelagic algae to export production.

Summary: Transports across the continental shelf edge have significant impacts on shelf-sea production, carbon removal, and ocean circulation. This study estimates the overall transport across the northwest European shelf edge in three different sectors using various measurements and estimates of processes contributing to exchange. The findings highlight the potential importance of these transports for shelf-sea and adjacent oceanic budgets. Fine-resolution models are crucial for further understanding and estimating the sensitivities of shelf-sea to the nearby ocean.

Summary: The Pacific sector of the Arctic Ocean, a region with the fastest sea-ice loss, is experiencing unprecedented biological regime shifts in its marine ecosystems today. This study provides the first detailed description of recent dinoflagellate cyst assemblages in the region, revealing strong regionalization in species composition and distribution, as well as the environmental factors driving these patterns.

Summary: The main sources of noise in the Arctic Ocean are naturally occurring, and sustained acoustic monitoring at high latitudes provides quantitative measures of changes in the sound field. The study presents a 12-month time series of ambient sound levels recorded near Gascoyne Inlet, Nunavut, showing a dependence on seasonal ice variations and higher frequencies varying more strongly. The analysis suggests that tidal-driven surface currents and ice block collisions contribute to the periodic trend in noise power.

Summary: The ongoing Arctic warming, combined with winter snowfall anomalies, can significantly impact sea ice thickness and extent in the following seasons, with potential reductions in both thickness and summer ice extent.

Summary: The coastal zone of the Canadian Arctic represents 10% of the world's coastline and is one of the most rapidly changing marine regions on the planet. This study found that kelp forests are abundant and cover a significant portion of the seafloor in the Eastern Canadian Arctic, despite the presence of thick sea ice and scarce hard substrata in some areas. The abundance and diversity of seaweeds in this region are influenced by sea ice cover, substratum type, and nutrient availability.

Summary: This study compares and analyzes the sea ice area and volume fluxes of Nares Strait and the Canadian Arctic Archipelago. The results show that Nares Strait has the largest ice flux, followed by the Queen Elizabeth Islands and M'Clure Strait. The majority of ice export comes from Nares Strait, with the highest fluxes observed in 2017-2019 and 2021, but remarkably exceeded by the Queen Elizabeth Islands in 2020. It is predicted that under continued warming, the ice export from Nares Strait and the Queen Elizabeth Islands will increase.

Summary: The 500-year history of naturally felled driftwood incursion to northern Svalbard reflects regional sea ice conditions and Arctic Ocean circulation. By analyzing provenance and age determinations, researchers gained insights into Arctic Ocean currents and climatic conditions with fine spatial resolution. The study indicates centennial-to decadal-scale shifts in source regions for driftwood incursion to Svalbard, aligning with fluctuations in Transpolar Drift and Beaufort Gyre strengths and associated climate conditions.

Summary: The study examined sea ice thickness estimates derived from ICESat-2, showing its high reliability in total freeboard but notable differences in SIT estimates compared to IceBird data, likely due to uncertainties from other parameters. The BMA method proved to be the best for SIT estimation, with potential error sources in ice density and snow depth that require further investigation.

Summary: Glaciers and ice caps in the Russian Arctic are experiencing accelerated mass loss due to atmospheric and oceanic warming in the Barents and Kara Sea region. There is a higher rate of loss over Novaya Zemlya in the west compared to Severnaya Zemlya in the east, with a quasi-linear relationship between surface elevation change and climate forcing. Ocean warming is identified as a key factor driving dynamic ice loss in Severnaya Zemlya.

Summary: The Arctic climate is changing rapidly, with declining sea ice and warmer upper-ocean waters. Research indicates that as sea ice melts and open water is exposed to the wind, more energetic internal waves may result, enhancing oceanic mixing and accelerating sea ice melt.

Summary: Landfast ice is immobile sea ice attached to the coast, playing important roles in coastal environments. Current sea ice models do not simulate landfast ice well due to its different dynamics from pack ice in the interior Arctic. The formation of landfast ice is linked to the local geography.

Summary: The study focused on the ecological and distributional aspects of benthic ostracodes in the Pacific-Arctic region, identifying six species with diagnostic habitat ranges. Statistical analyses revealed that ostracode assemblages were influenced by summer water masses and complex water mass characteristics across different spatial scales. Dominant species remained fairly constant over recent decades, but there were slight increases in abundance of certain species, indicating a potential response to changing water mass properties in recent years. This ecological data suggests hypotheses for future benthic monitoring efforts.

Summary: This paper examines the sea ice conditions in the Beaufort and Laptev seas of the Arctic using remote sensing data from satellites. The study focuses on the differences in sea ice area, concentration, and thickness between the two regions from 2010 to 2021. It is found that the Laptev Sea has a lower range of sea ice area and thickness compared to Beaufort, indicating higher variability in Beaufort. The use of sea ice thickness as a variable during winter months provides valuable insights into sea ice growth, benefiting modelers and navigators for better forecasting.
