Atlantification drives recent strengthening of the Arctic overturning circulation A less ice-covered Arctic shifts dense water formation northward, strengthening the Arctic Ocean overturning circulation.

The Arctic Ocean acts to stabilize the AMOC

New paper in #ScienceAdvances by researchers from @bjerknes.uib.no and @oxuniearthsci.bsky.social showing how ongoing Atlantification and sea ice loss leads to a strengthening of the Arctic overturning circulation.

Very cool article about Kjetil Våge’s ROVER project and how the Nordic Seas could help to decide the fate of the AMOC.

Er Golfstrømmen på vei til å gå amok? Vi tar pulsen på havstrømmene våre neste uke (torsdag) på klimafestivalen Varmere Våtere Villere. Kan de stoppe opp?

The future Barents Sea—A synthesis of physical, biogeochemical, and ecological changes toward 2050 and 2100 The Barents Sea is a hotspot for ongoing Arctic climate change, manifested in a rapid warming of the ocean and the atmosphere and a strong decline of the winter sea-ice cover. These changes in the phy...

Buoys on Expedition in the Arctic Ocean Two instrument-laden buoys ("Knoll" and "Tott") were recently released north of Svalbard, soon to disappear beneath the ice.

In our project "Overturning circulation in the new Arctic" (ArMOC) we have deployed two Argo floats in the Arctic (north of Svalbard). A short story on the mission of Knoll & Tott here:

Could the AMOC collapse and Bergen become 20 degrees colder (imagine the snow we would get!)? This and more in the latest Bjerknes podcast.

The Barents Sea is a hotspot for ongoing Arctic climate change and could be 7C warmer by 2100. Check out our amazing fact sheets from the Nansen Legacy project! arvenetternansen.com/fact-sheets-...
