5 years in the making; glad to have this one over with. Where we show that sure, you can use advanced #NeuralNetwork and #DeepLearning if you feel like it, but basic linear regression does the job as well, faster, and does not burn the planet. #AI agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Drivers of Interannual to Decadal Sea Level Variability in Northern Europe—Data Driven Approach

We analyze sea level variability in northern Europe using neural networks and linear regression combined with permutation feature importance Sea level is mainly driven by local atmospheric forcin...

New study led by @marylouathanase.bsky.social and @raphaelkoehler.bsky.social. As #SeaIce thins, the Beaufort Gyre releases its feshwater out of the #Arctic. We don't predict the "Day After Tomorrow" but I'm curious about potential impacts on the #AMOC agupubs.onlinelibrary.wiley.com/doi/full/10....

The Arctic Beaufort Gyre in CMIP6 Models: Present and Future

CMIP6 models generally simulate a too strong, large, and northward-extending Beaufort Gyre (BG) during the historical period Among the least unrealistic models, most simulations project a decline...

Our new study is out: The Arctic Beaufort Gyre is projected to weaken or vanish in most CMIP6 models under future climate change. The gyre would thus stop storing freshwater in its centre, with possibly large impacts on the Arctic and beyond. Read: agupubs.onlinelibrary.wiley.com/doi/full/10....

Drivers of high frequency extreme sea level around Northern Europe – Synergies between recurrent neural networks and Random Forest

Abstract. Northern Europe is particularly vulnerable to extreme sea level events as most of its large population, financial and logistics centres are located by the coastline. Policy makers need infor...

Has the Atlantic Meridional Overturning Circulation (AMOC) weakened over the last decades? In our new study, we combine state-of-the-art CMIP6 models and observation-based estimates of the air-sea heat flux in the North Atlantic to show that the AMOC has not declined since the 1960s! 🌊

Atlantic overturning inferred from air-sea heat fluxes indicates no decline since the 1960s - Nature Communications

The AMOC is crucial for the global ocean overturning circulation and controls the climate around the North Atlantic. Here, the authors use 24 Earth System Models from the CMIP6 to demonstrate tha...

Our new #polynya study (large team led by Igor Dmitrenko) is finally out in Ocean Science! Follow the link to learn more about the role of sea ice openings (i.e., polynyas & leads) for driving the DVM of zooplankton in the Laptev and Beaufort seas - os.copernicus.org/articles/20/...

Contrasting two major Arctic coastal polynyas: the role of sea ice in driving diel vertical migrations of zooplankton in the Laptev and Beaufort seas

Abstract. The diel vertical migration (DVM) of zooplankton is one of the largest species migrations to occur globally and is a key driver of regional ecosystems and the marine carbon pump. Previously ...

Hello X-migrants. Have some #pancakes from our last day in the #Arctic #SeaIce, 6 weeks ago already

Internet is quite patchy so I've been unsuccessfully trying to post these for days. Anyway: Thick #SeaIce!!! Multiyear, more than 2m+ #Arctic #ImBlue

Did you know? #ice is actually blue. Fitting for this app ;) #Arctic #SeaIce #PS144

Not much happened for our team today, so we had time for training. Pic: Olli showing how to open and close the CTD bottle taps to collect water samples #Arctic #fieldwork #PS144

Good morning #Svalbard! @willharcourt.bsky.social "see" you in a few hours

We're on our way to the #Arctic! Bright sky and high temperatures while leaving the Tromsø fjord on the R/V #Polarstern

Officially, it's still 24h darkness here. In practice, it is quite bright for 2-3h, similar to summer in Europe when you look to the west at sunrise, especially on a clear day like today. #Arctic #MiddayNight

Guess who is teaching at #UNIS this week? #Svalbard #Arctic

FYI I fell out of love with #socialmedia in 2023, so I won't post much here for now. Will probably spam you with #Arctic #fieldwork pictures this summer though :)
