Currently a large outbreak of cold, Arctic air is making its way south over the Norwegian Sea. The amazing mesh structure (called open-cell convection) in the satellite image (coloured image) is really hard for weather forecast models (grey image) to get 'right' @bjerknes.uib.no #ISOSCAN_project

Early career researchers need proposal writing skills. Therefore a new way of teaching proposal writing was developed. It is now accessible to the research community.

By applying a tracking method to both climate models and satellite data, @davyclimate.bsky.social found that sea ice age is a more sensitive indicator of change than ice thickness or volume.

In the Arctic, sea ice has a leading impact on ocean surface dynamics, mainly in the regions that are seasonally ice-covered. Supply et al., examine the seasonal cycle of the ocean surface conditions in the seasonal ice zone 🌊

If you're interested in sea ice and how we can track its development, you may want to sign up for our 1-day seminar where we'll be talking about the breadth of ECVs for sea ice, new developments in tracking sea ice age, and the pitfalls and opportunities of climate model - observation comparisons.
📣 Join our Webinar "Beyond Sea Ice Area" on September 19th.

Sea Ice Age is the focus🔎

Main topics:
1. Review ECV sea ice products
2. Refine sea ice age product
3. Explore polar data issues

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.
