❄️Theory and practice❄️
In Sisimiut, Greenland, we teach a DTU course called Extreme Climate and Physical Nature on the Arctic Semester. Earlier this week 30+ students practiced drilling in the ice on the lake in the center of town after learning the theory last week.

Mikkel suited up for field work in front of a snowcooter on Svalbard

Our PhD Student @mikkelaabykruse.bsky.social is currently getting a taste of what it is like to do fieldwork in the Arctic at The University Centre in Svalbard (UNIS)❄️🥽 🧤 Working on a glacier is no safe or easy task, and UNIS is a great place to learn the ropes of what it means to be a glaciologist!

🚀 Excited for Copernicus @esa.int #CRISTAL! This mission’s dual‑freq Ka/Ku #altimeter aims to measure snow depth on sea ice. A new UiT‑led study (feat. @reneefredensborg.bsky.social) explores current laser/radar data + simulates CRISTAL waveforms. Check it out ➡️ tc.copernicus.org/articles/20/... ❄️🧊

🍾🥂One of our most exciting pieces of news this month must be the hand-in of Anna Puggaard's PhD thesis on "Earth observation for surface mass balance" on January 15, celebrated with cake and bubbles! We look forward to seeing her in the office as a postdoc in February, after a well-deserved break! 🏝️
28.01.2026 14:09 — 👍 6 🔁 3 💬 0 📌 0Overall, a critical and interesting study - definitely worth the read, if we do say so ourselves 😜 - and one of the first to synthesise measurements from multiple types of satellites and tackle the complicated issue of ice sheet firn evolution directly from space 🛰️
23.01.2026 14:05 — 👍 0 🔁 0 💬 0 📌 0Supported by @esaearth.esa.int Living Planet Fellowship, this exciting study brings together a decade(!) #CryoSat-2 #SARAL/AltiKa and #SMOS satellite data to show how vertical heterogeneity in the Greenland firn layer evolved between 2013-2023, with important implications for storing surface melt!❄️

📢 Going to #EGU26? Do you work with #radars on icy and rocky surfaces? ➡️Look no further!
Submit an abstract to this session, convened by our @kirkscanlan.bsky.social and @reneefredensborg.bsky.social with Hameed Moqadam! The deadline is fast approaching ⌛ - submit by 15 January 2026 at 13:00 CET!
Great to be at the 2026 Greenland Ice Sheet Seminar at the Niels Bohr Institute with cryosphere colleagues.

🌟Meet our Group🌟
@mikkelaabykruse.bsky.social is a PhD student in the Cryo Group. He uses satellite remote sensing to study lakes hidden beneath the Greenland Ice Sheet 🛰️🧊🌊 Some of these lakes can contain and later release enormous amounts of meltwater. #Cryosphere #RemoteSensing #Greenland
To round off the year and just before Christmas, I had the amazing opportunity of spending the last week in Calgary, Alberta, meeting my colleagues at @ucalgary.bsky.social while participating in the ArcticNet's Annual Science Meeting #ASM25, and presenting my #MEOPAR funded project #SNOWMASS ❄️🛩️🛰️! ➡️

🌟Meet our Group🌟
Sebastian B. Simonsen (@eo4cryo.bsky.social) is a senior researcher using satellite altimetry to study ice sheets, sea-level change, snow, and ice dynamics. Lately focused on data-driven models and digital twins. PI for Digital Twin Ice Sheets. Also involved in C3S and CCI.
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
09.12.2025 17:16 — 👍 6 🔁 4 💬 0 📌 0We have provided new Greenland Ice Sheet mass loss estimates to @polarportal.bsky.social. These are derived from the #GRACE and #GRACE-FO missions, and show that since the launch of GRACE in 2002, the ice sheet has lost approximately 5200 gigatonnes of ice!

Heading to #EGU26 and use #radar to study terrestrial and planetary surfaces (both icy and rocky 🤯)? Have we got the session for you!
Consider submitting an abstract to #EGU26 CR6.3 by January 15 2026.
Read more about the session here www.egu26.eu/session/56853
Hope to see you there!
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🧊❄️🎄

Rasmus 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.🌍❄️
Last week we attended DTU Project Day and had great conversations with many interested students about potential new projects 🛰️❄️

📢 New publication! Ahead of #ESA #CRISTAL, we explore dual-frequency #altimetry for estimating 🧊 snow depth over sea ice.
🛩️ Part 1: Airborne multi-freq altimetry → snow depth 👉 tc.copernicus.org/articles/19/...
🛰️ Part 2: Compare w/ CryoSat-2 & ICESat-2 #CRYO2ICE 👉 tc.copernicus.org/articles/19/...
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.
