Our graphic shows Arctic sea-ice ridges aren’t just rubble—they’re biomass hotspots.
In summer, they can hold up to ~80–100% of ice-algal biomass despite covering much less area. Their complex structure creates diverse microhabitats for microbial life.

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
🧪 🥳 Its not every day that a group of research advisers publish in a scientific journal!
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.

Fisheye photo of a massive green and red curtain of aurora taken from a pier next to a fjord. The pier can be seen in the lower right corner with some people on it and few trees to the right. The fjord and the land on the other side can be seen on the lower left part of the picture. Finally the aurora appears like a massive mountain of light rising from the sea to, almost, the top of the picture. It presents shades of green and yellow on its lower part, with the majority in bright to deep red. Finally, of strong reflection of the aurora appears on the sea in a curved lower band in the pic.
Last year on this day, we had what is so far the best aurora show I ever saw in Bergen... and by far! It was also the first night I could play with my new fisheye lens. I had a lot of fun! I am really looking f... Read more on Instagram: https://www.instagram.com/p/DPoS7dUAjM6/
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.
🧪🌊 Read the publication here: agupubs.onlinelibrary.wiley.com/doi/epdf/10....
We have a new paper out today taking a fresh look at sea ice age, showing how this variable offers new insights into Arctic climate change:
A Fair Assessment of Sea Ice Age Reduces Bias and Gives New Insight to Arctic Sea Ice Dynamics

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.
Bar chart for Lisbon, Oslo, Paris, Rome, Vienna showing blue bars (tropical nights) vs orange bars (tropical 10 pms) in 2025 so far. Orange bars tower over blue in every city except Rome, highlighting bedtime heat.
🌡️ Not all hot nights are equal. We track “tropical nights” when temps never dip below 20 °C—but what if it’s already 20 °C at bedtime? I crunched ERA5 data for 5 European capitals. Let’s talk tropical 10 pm. 👇
