AMOC is upheld by cooling in the north. But where is north? @jakobdoerr.bsky.social and colleagues from the Bjerknes Centre, @unibergen.bsky.social, @nansensenteret.bsky.social, @stockholm-uni.bsky.social and @noc.ac.uk investigate dense water formation in the Arctic. bjerknes.uib.no/en/news/golf...

Polar oceans influence the Gulf Stream

The warm Gulf Stream is maintained by coldness. The Barents Sea is a cooling machine.

🌊Where and how is dense water in the Arctic formed? In our new paper, we decompose the Arctic overturning circulation (ArMOC), the northernmost part of the AMOC. Check it out 🔽 @bjerknes.uib.no @mariusarthun.bsky.social @kristoferdoos.bsky.social @nansensenteret.bsky.social @noc.ac.uk

The Arctic overturning circulation: transformations, pathways and timescales

Abstract. The Arctic is the northernmost terminus of the Atlantic Meridional Overturning Circulation and is an important source of the densest waters feeding its lower limb. However, relatively little...
