Ice-free conditions continue in the Barents Sea region of the #Arctic Ocean. This is one area that has observed some of the largest losses of ice over the last few decades... compare the older years (dark/purple lines) to today!

How will a sudden change in the function of the ocean circulations impact Iceland, Europe, and the world?
We had a great panel at the Arctic Circle Assembly 🌊🧪
It was a scientific discussion on the likelihood, uncertainties, and possible consequences if the large ocean circulation were to shift.

Newly published study led by @leonchafik.bsky.social finds that anomalies in temperature and salinity that originate in the midlatitude North Atlantic can affect the #AMOC in the Nordic Seas up to a decade later.❗️ 🌊

Nice paper led by @leonchafik.bsky.social on the North Atlantic-Nordic Seas overturning circulation.
Warm & salty North Atlantic water transport to the Nordic Sea (NS) across the Greenland-Scotland Ridge (GSR) didn't show a slowdown since 1972. Instead, it exhibited multidecadal variability. The NS overflow & AMOC across the GSR also display a similar signal. 🌊🧪👍 doi.org/10.1038/s43247-025-02557-x

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.

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.
