We’re the Cryosphere Research Group at DTU Space, studying the polar regions using satellite remote sensing. We monitor and map changes in snow & ice, assess polar climate change impacts, and provide data to imporve polar climate models. Follow for polar science insights! ❄️#Cryosphere #PolarResearch

As part of #AMAP’s collaborative process, the first draft of the Arctic Land Ice chapter for the upcoming 2026 Assessment Report is now being circulated to national representatives across Arctic nations. Their input will help ensure that key datasets and perspectives are represented across borders.

We are proud to be contributors to a chapter on Arctic land ice and its changes in the #AMAP Assessment Report 2026!❄️

#AMAP (Arctic Monitoring and Assessment Programme) is the working group under the #ArcticCouncil that produces science-based assessments to inform policy and decision-making ❄️

🌍✨Great energy at DTU Space with a visit from Unge GIS Brugere!

Yesterday, we welcomed GIS users to #DTUSpace. The visit focused on spatial data from #EarthObservations and methods for tackling geospatial challenges, highlighting the importance of precise geospatial data in the Arctic and beyond 🌍❄️
Mai is presenting PRODEM for the 2019 summer, focusing on three big outlet glaciers. More interested in PRODEM? Have a look at the paper: https://doi.org/10.5194/essd-16-5405-2024

Congratulations to Behzad Forouzi Feshalami for defending his PhD thesis: "Numerical modeling of wave-induced erosion of floating icebergs" - a valuable contribution to improving our understanding of ice–ocean interactions! 🌊🧊

In collaboration with #NTNU, supervised by @spacehsk.bsky.social 🎓

The goal is to test #CRISTALair, the new airborne demonstrator procured by ESA to support the upcoming #Copernicus #CRISTAL mission. #CRISTAL will deliver key observations of sea-ice thickness, snow depth, and land-ice elevation changes, supporting climate research and sea-level rise monitoring🛰

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 ⬇️
Preparing for some UAV flights in the eerie field work weather at the Finnish Siikaneva wetland. A UAV image looking down on the Finnish Siikaneva bog site. From the different vegetation microtopographies, we could quantify the wetland's methane emissions throughout the seasons.

Presentations and discussions focused on the state-of-the-art and the future of the field. From ground-based to airborne and satellite observations of sea ice, seasonal snow cover, and all the way down to the bottom of ice sheets, the future of polar remote sensing is looking bright and vibrant 🤩

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 🛰️❄️

Welcome to our new bachelor students! 🎓

Yesterday marked the start of the new study year at DTU, where we welcomed 42 new bachelor students to our Earth and Space Physics and Engineering programme. Our head of study Sine Hvidegaard made sure the students got a good intro to their new student life.

Congratulations to DJ Upside Down Turtle and DJ Disco Disc for their triumph in the inaugural Cryosphere Group Disc Golf Championship! 🥳🥳
A lovely afternoon spent with great colleagues and only "a few" discs had to be dug out of trees or fished out of water. Time to start practicing for next year 🙃
The winners!!
