Observed Arctic sea ice losses are a sentinel of anthropogenic climate change. These
reductions are projected to continue with ongoing warming, ultimately leading to an ice-free …

Climate change is impacting marine ecosystems throughout the circumpolar Arctic, altering
seasonal habitats and the food bases for fishes, seabirds, and marine mammals. Arctic and …

Strong seasonality is a key feature of high-latitude systems like the Barents Sea. While the
interannual variability and long-term changes of the Barents Sea are well-documented, the …

Mass loss from the Greenland ice sheet has contributed to global sea-level rise over the past
20 years. Yet direct observations from the 79 North Glacier (79NG) calving front reveal …

The Arctic Ocean's Eurasian Basin underwent notable atlantification during the 2010s,
characterized by warming of the Atlantic Water layer and increased upper ocean salinity …

Abstract The Atlantic Water, entering the Arctic through the Barents Sea and Fram Strait, is
the main source of nutrients in the Arctic Ocean. The Barents Sea is divided by the Polar …

The sea‐ice cover in the Barents and Kara Seas (BKS) displays pronounced interannual
variability. Both atmospheric and oceanic drivers have been found to influence sea‐ice …

Atlantification—the northward inflow of anomalous waters and biota from the Atlantic into the
polar basins—has wide-ranging climatological ramifications. We present previously …

Located at the confluence of the Arctic and North Pacific and with Alaska at its heart, the
Pacific Arctic Region (PAR) is a unique and interconnected regional climate system …

The Arctic sea ice cover has decreased rapidly over the last few decades both in extent and
thickness. Here we present multi‐year (2013–2022) observations of sea ice thickness in the …
