Can a satellite built to measure changes in ocean and river water levels also reveal meltwater's hidden pathways deep beneath the Greenland Ice Sheet? ❄️ Happy to share that Senior Researcher Mai Winstrup has received a grant from @VILLUMFONDEN to investigate exactly this!

Want to learn how we can connect #EO, in-situ, and modeling data with graphs and data cubes to better understand our ice sheets? 🇬🇱🇦🇶 Then tune in on Monday (28/9), to @esaearth.esa.int's webinar, where @tabea-rettelbach.bsky.social & colleagues will give some cool insights! 🧊 registration link 👇

This week we are in Svalbard for #VOCALIS2026, ESA's altimetry Cal/Val workshop (vocalis2026-workshop.noveltis.fr) 🛰️❄️ Kristina Belinska & Stine Kildegaard Rose gave talks on CRISTAL sea ice and Sentinel-3 land ice. Today, @spacehsk.bsky.social opened the final day on uncertainty quantification!

Many exciting things this week! @louisesandbergs.bsky.social and @eo4cryo.bsky.social are in Innsbruck at the #ESA Polar Science Cluster Collocation Meeting 2026. 🛰️ Here, we are sharing our project outputs and learning from other initiatives. More info: nikal.eventsair.com/polar-scienc...

Nearly 5 decades of satellite data reveal the scale of polar ice loss🧊 Using data from 27 missions, including @esa.int's CryoSat & Copernicus Sentinels, a new study found that Greenland and Antarctica lost 11.3 trillion tonnes of ice since the 1970s: www.esa.int/Applications... 📹Otosaka et al(2026)

Welcome, Copernicus Sentinel-3C! 🛰️

Last week, our @kirkscanlan.bsky.social attended the @igsoc.bsky.social #Radioglaciology symposium in Tübingen 🇩🇪 Here he presented some the great work coming out of the @esaearth.esa.int #ARCTEX project using 🛰️s to study extreme Arctic events 🤯 Overall a fantastic meeting with amazing research!

If you haven't already, check out @nataliahavelund.bsky.social new paper on monthly Greenland Ice Sheet surface elevation changes! 🛰️

esaclimate@esaclimate.bsky.social · 2mo ago

New ESA-funded research turns CryoSat-2 observations into continuous monthly maps of Greenland Ice Sheet surface elevation change. The new method captures both seasonal and long-term changes, even where satellite observations are sparse. 🛰️❄️ doi.org/10.5194/tc-2...

This week, Sebastian (@eo4cryo.bsky.social) is heading to the International Space Summit in Paris (9-10 Sept), joining a round table on Intelligent Space Science! 🛰️❄️ Talking points: sustaining Europe's full research pipeline, and how #AI can help spot ice-sheet tipping points before they happen ❄️

At the @esa.int #PISCO and @snowpi.bsky.social hackathon last week, Anna, Kirk, and Tabea joined 30+ researchers from around the world to dig through gigabytes of #EO and climate model data to tackle some exciting polar questions ❄️ 🧊 Let's dig into a couple below👇

For the second year, our group has joined the national Vi Cykler Til Arbejde #vcta (We Bike to Work) campaign in the month of May! 🚴‍♂️🚴‍♀️💨💨 Our "Polar Pedalers"❄️🥶 team biked 166 days and 2767 kilometers with Anna and Kirk leading the team in total bike days and bike kilometers!

One of the ways we study Greenland Ice Sheet mass balance: tracking annual changes in ice surface elevation using CryoSat-2 and ICESat-2. A popular science piece (in Danish 🇩🇰) out now in @Geoforum issuu.com/geoforum5/do... #PROMICE #PRODEM #Massbalance

The @imaqa.be SILA expedition has completed its 1,700 km ski kite traverse of the Greenland Ice Sheet, reaching Qaanaaq on May 18th 🎉 All four explorers are home safe and the GNSS elevation data collected for DTU Space is on its way. Proud to have supported the science behind this exciting mission.

DTU Cryosphere group@dtucryo.bsky.social · 6mo ago

We are a scientific partner of the SILA Greenland Mission 2026 with IMAQA ❄️ Using ski kites, the expedition will traverse the Greenland Ice Sheet from South to North and collect GNSS elevation data on behalf of DTU Space 🔗 www.imaqa.be/sila Sila means both weather and state-of-mind in Kalaallisut 🇬🇱

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 🌍🧊

Excited to share 📄✨ our new paper on #Sentinel-3 radar over the #GreenlandIceSheet - accepted in #IEEEJSTARS & out as a preprint: ieeexplore.ieee.org/document/115... 🔍 It started with an unusual signal: very low radar backscatter in N Greenland (summer 2023)…

Regional Differences in Sentinel-3 Radar Backscatter over Greenland and its Impact on Ice Sheet Altimetry Applications

Greetings from Karthaus. It is always a pleasure to be back in the beautiful setting of the Karthaus summer school. This year, Rasmus is attending the course, and Nanna and Louise are teaching.

Kicked off May at #EGU26 in Vienna - a week packed with talks, posters & inspiring discussions. Back in the office full of fresh ideas 💡 - and thanks to sunny weather + rental bikes, the #BikeToWork #VCTA streak rolled on even from Vienna 🚴‍♀️ #PolarPedalers
