Little researched current impacting on winter sea ice in the Arctic

New simulations show that a weakening return flow of Atlantic water from the Barents Sea allows more warm water to reach sea ice, accelerating winter sea ice loss. This overlooked mechanism is key to understanding Arctic climate change.

Sea ice plays important role in variability of carbon uptake by Southern Ocean
Alfred Wegener Institute (AWI)
Published: 20 June 2025
The Southern Ocean’s CO₂ uptake varies annually, driven largely by winter sea ice. More persistent sea ice reduces CO₂ release, boosting net uptake. This highlights winter’s key role in the carbon cycle and the need for more cold-season data.
