We finished the month of May with a DTU Cryosphere Pétanque (or Boules) Tournament in the sun ☀️🌻 The winning team was "Mass Balance Issues"!
Excited to share that the first version of the @esa.int #DTCIceSheets is now available! 🎉 You can now explore this big step toward an interactive #EO-driven #DigitalTwin via the platform and its datasets, modules, and use cases for Greenland and Antarctic ice sheets online on dtc-ice-sheets.org 🌍🧊

☀️ Spring has finally arrived in Copenhagen ☀️ The team celebrated the good weather by painting flower pots and planting some (small-ish) sunflowers to brighten up our offices during our social event🌻
🚨 Applications open! Join us for The Polar Climate Space: a week‑long #hackathon (24–30 Aug) bringing together #ECRs to tackle #Arctic & #Antarctic challenges using #EO, #climate models, in‑situ data & #ML. More info below! 👉 ECR form: tinyurl.com/ycy57mvj 👉 Senior scientists: tinyurl.com/2p9tv992
Last week, researchers came together for the Danish Antarctic Science Seminar at @ucph.bsky.social to discuss the most recent studies of Antarctic science! @tabea-rettelbach.bsky.social showed how the @esa.int Digital Twin can be used to explore "what-if" scenarios for the Antarctic Ice Sheet ❄️
If you're interested in the long-term development of polygonal ice-wedge terrain in Alaska after a tundra fire, then check out my newly published paper (or the TLDR version below 🙂) doi.org/10.1088/1748...
DTU Cryosphere group@dtucryo.bsky.social · 5mo agoNew paper alert! 📄 How do Arctic tundra landscapes develop after a wildfire? 🔥 Using high-resolution lidar DEMs and a space-for-time approach, @tabea-rettelbach.bsky.social examined how ice-wedge polygon terrain in Alaskan permafrost landscapes changes following a fire. doi.org/10.1088/1748...
One year into the ESA Digital Twin (DT) Earth Ice Sheets project ❄️@eo4cryo.bsky.social and @tabea-rettelbach.bsky.social with other @esa.int DTs at the science meeting in Frascati to present the pre-operational dtc-ice-sheets.org & new ideas for holistic data cubes 🛰️🌐 #DigitalTwinEarth #IceSheets
Our colleague @tabea-rettelbach.bsky.social is developing dynamic data cubes for #EO data over ice sheets (literally 🧊). The goal is to make complex geospatial datasets easier to find, access, and use for e.g. modelers. #datacubes @icelink-project.bsky.social #PISCO #DTC_icesheets
It may be difficult for the untrained eye to see - but we were of course dressed in the colors of glaciers at last weeks Christmas party at DTU Space🧊❄️🎄
After joining many many hackathons as a participant in the past years, this is the first time for me as an instructor; and I'm loving the experience and motivational atmosphere just the same! Thank you @polarres.bsky.social for making this possible 👩💻
DTU Cryosphere group@dtucryo.bsky.social · 9mo agoRasmus and @tabea-rettelbach.bsky.social are in Budapest this week at HungaroMet for the PISCO & @polarres.bsky.social hackathon! 🇭🇺 With 20 other students and instructors, they’re exploring projects that combine climate model outputs with in-situ and EO data to better understand our Polar regions.🌍❄️
AWI researchers have mapped 19,000 driftwood in Alaska and northwestern Canada for the first time. The data will help to better understand coastal processes, carbon storage and environmental changes such as storm surges and erosion. www.awi.de/en/about-us/... Photo: Carl Stadie
Die @zeit.de hat über einen See in Alaska berichtet, der aufgrund der Degradation von #Permafrost ausgelaufen ist und über damit zusammenhängende Forschung des @awi.de sowie Kooperationspartnern (Geschenk-Link): www.zeit.de/2025/44/klim....
Klimawandel: Und plötzlich war kein See mehr da
In Alaska verschwindet binnen Stunden ein See. Der Grund: tauender Permafrost. Forscher wollen nun wissen, wann das System kippen könnte und ganze Landschaften verändern.

Last week, @eo4cryo.bsky.social and @spacehsk.bsky.social were in Iceland and NE Greenland on an airborne #FieldCampaign sampling key data over #SeaIce and #LandIce with a brand-new instrument #CRISTALair🛩 Cutting-edge science in action, unlocking insights for future satellites🛰 #EarthObservation
Three new papers co-authored by @tabea-rettelbach.bsky.social have just been published! A little outside of our usual focus on the cryosphere, as these studies span broader Arctic remote sensing applications: aerial imagery 🛩️, methane emissions🫧, driftwood 🪵. Details and links in the comments ⬇️
Brand new website for the Cryo Group at DTU is now live! Thanks to @reneefredensborg.bsky.social for making us look so good 🤪 www.space.dtu.dk/english/rese...
Cryosphere
In the Cryosphere Research Group at DTU Space, we monitor the recent and ongoing changes of the ice-covered regions of the Earth, including ice sheets and sea ice, using observations from satellites, aircraft and ground. During the past decades, satellites have observed a decline in sea ice and an increased mass loss of the Greenland ice sheet. Our research leads to an increasingly accurate understanding of these rapid changes, thus enabling society to mitigate climate change.

These past three days, @reneefredensborg.bsky.social, @tabea-rettelbach.bsky.social & @kirkscanlan.bsky.social participated in the Symposium on Technology Advancement for Ice Remote Sensing (STAIRS) in Copenhagen, organised by the University of Copenhagen and the University of Manitoba 🛰️❄️
