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. 👇

Not bad at all! neXtSIM was mostly designed to represent the deformations of pack Arctic sea ice, so we wanted to check which opportunities it could offer in the Antarctic. Our results suggest that neXtSIM does pretty well at capturing the ice response to storms in regions like the Weddell Sea. 2/3

Happy to share our last study published in JAMES! In the manuscript led by R. Santana from NIWA, we tested our in-house sea ice model neXtSIM in the "other" hemisphere, to see how it would perform with Antarctic sea ice! And the answer is... 1/3

After years of saying "it wouldbe fun", we did it! We cycled from home to Solstrand (34km) for our annual internal seminar at @nansensenteret.bsky.social !
A lovely morning ride in the rising sun despite the freezing toes.

Research article: The Arctic Beaufort Gyre in CMIP6 Models: Present and Future
🆕 from PolarRES' @raphaelkoehler.bsky.social & colleagues on the future of the Beaufort Gyre, a major Arctic Ocean current.
By accumulating/releasing freshwater, it shapes ocean properties.
But most CMIP6 models project it will weaken or vanish, disrupting ocean circulation.

If you are into modeling of sea ice physical properties (salinity, brine volume, or density), we combined coring datasets to have a seasonal evolution for first- and second-year level ice: doi.org/10.5281/zeno...
The coring datasets have many more parameters, including isotopes and nutrients.
Picture of a measurement site on the Greenland Ice Sheet. In the foreground is a fixed‐wing uncrewed aerial system (UAS), looking like a small, light plane with a wing span of 3 m. The UAS is prepared for take-off on a launching system with a high pressure flask that is filled with air through a connected compressor. In the background are white, heated measurement cabin and a turbulence measurement system (eddy covariance) that is connected with a thick bundle of cables to the cabin.

🧪 We present a unique dataset of 465 (!) in situ measurements of the #water_isotopes in vapor up to 1500m above the #Greenland Ice Sheet.
🌍 We demonstrate the use of water isotope profiles to reveal gaps in climate model physics.
🌊 Winds can make very big waves but very often nobody is there to see them in their full height. However, we do get swells radiated from these. I've just published two datasets about very big wave heights here: www.seanoe.org/data/00940/1.... www.seanoe.org/data/00942/1... next one: wave periods
