🚨 New preprint 🚨

We compare 6 sea-ice biogeochem models vs. data 📊

Biomass: tunable ✅
Nutrients: still tricky ❌

Read more on #EGUsphere → doi.org/10.5194/egus...

🙏 all co-authors & @bepsiiseaice.bsky.social for supporting this study!

#IceVar will create a high-res time series of ice types & biological patchiness in the summer Arctic pack ice ❄️🔬🌍

Supports relevant initiatives like #ArcticCouncil #SAON, #Copernicus Arctic Hub, EU #ObsSea4Clim & is an integral part of my pending proposals to the Research Council of Finland.

🟣 Why?

Because Arctic icescapes = habitats 🦠🐋

We still don’t fully understand how sea ice changes affect ecosystems, biodiversity & productivity as the Arctic warms. #ClimateChange

🟢 We’ll track:

🌡️ Ice thickness (ship, EM, drones)

🧬 Biogeochemical properties across ice types & under-ice waters (in situ, FerryBox, drones)

💥Exciting news! Our #IceVar proposal to #POLARIN was selected!💥

In summer 2026, I’ll join 8 Arctic transits aboard #PONANT's #LeCommandantCharcot from #Longyearbyen to the #NorthPole with Jari Haapala (FMI) & @ChristianHaas (Uni Bremen). ❄️🛳️🗺️

During #COP29, I had the honour of reading an🚨Open letter: An S.O.S. from the Poles to World Leaders.

What started as a chat grew into something unimaginable!
