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...
Bergen calling! Postdoc position at @unibergen.bsky.social and @bjerknes.uib.no focused on the Arctic Ocean and its impacts on the Atlantic overturning circulation (AMOC). The position is part of the national Arctic Ocean 2050 program. www.jobbnorge.no/en/available...
Deadline approaching for 3-year postdoc position in Bergen.
🌊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
Come join us! PhD position at @unibergen.bsky.social and @bjerknes.uib.no on freshwater transport from the Arctic Ocean and its impacts on the Nordic Seas and subpolar overturning circulation. The position is part of the national Arctic Ocean 2050 program. www.jobbnorge.no/en/available...
Thirty years of in situ observations indicate that a vital ocean current is losing its chill, transporting warmer water to the Arctic. 🌊🧪 ocean2climate.org/2026/01/05/a...
