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.

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

Good news for the Gulf Stream! A study from @unibergen.bsky.social, the Bjerknes Centre and @ox.ac.uk indicates that the Arctic Ocean compensates for less deep water formation farther south. @mariusarthun.bsky.social @ailinbrakstad.bsky.social @jakobdoerr.bsky.social

New Book:
The Barents Sea system
Gateway to the changing Arctic

Happy to contribute to some sections of this exciting book!

From sea ice to the atmosphere, Earth’s systems are more interconnected than you think! Take a tour with this interactive illustration and see how climate models help scientists uncover the mysteries of our planet.🧪

To celebrate #CTDAppreciationDay, here's a video of a ride-along with a CTD in a (biologically active) Norwegian fjord during a student cruise! 🌊

In our project "Overturning circulation in the new Arctic" (ArMOC) we have deployed two Argo floats in the Arctic (north of Svalbard). A short story on the mission of Knoll & Tott here:

The Barents Sea is a hotspot for ongoing Arctic climate change and could be 7C warmer by 2100. Check out our amazing fact sheets from the Nansen Legacy project! arvenetternansen.com/fact-sheets-...

A good opportunity for a first post. Come work with us!

The northern Barents Sea could be 7 degrees warmer in 2050. Two scenarios, one a 4 degree increase and the other a 2.5 increase showed similar results.

"One of the main findings is that you can't see a difference between these scenarios in 2050," says researcher Marius Årthun, with UiB and BCCR.🧪🌊

Starting in 2025, March 21 becomes the #WorldDayForGlaciers 🧊. Living in Norway I know the white beauties' magic 🏔️❄️ - being German, I know how it is to lose all of them in the next decade. What are the costs of cultural and environmental heritage for our limitless emissions? #ClimateAction

We have a new doctor in the house! Many congratulations Dr. Jakob Dörr @jakobdoerr.bsky.social, who defended his thesis "Present and future drivers of Arctic sea ice variability" today!
Read his latest publication here:

New paper alert: While ice-free conditions in September are now likely unavoidable, with first ice-free days possible within the next decade & likely before 2050, future emissions will determine how frequently & for how long the Arctic will be ice-free. rdcu.be/dApgx

Got some Lagrangian perspective on the flight home from #OSM24

Well done @jakobdoerr.bsky.social 👏

Getting ready for Monday of #OSM24 🌊🔭✨

I'm excited for #OSM24! If you are interested in sea-ice variability, come see my talk on Thursday at 9:36 AM about causal links between Barents-Kara sea ice and oceanic and atmospheric drivers. Preprint here: doi.org/10.22541/ess...

Also happy to meet, hang out, or discuss 🙂

Check out our new paper on the contribution of vapor fluxes to the surface mass balance of the Greenland Ice Sheet! 🧐🤓

We find that sublimation is a major driver of the summer SMB in the accumulation zone, removing about a third of the snowfall in June and July. 🌨️
