It has been a great meeting full of interesting scientific discussions, networking, aurora - and an excursion into a glacier in very nice weather! There is still a lot of work to go, but very exciting results already in-hand and more on the way!

DTU Cryosphere group @dtucryo.bsky.social · 01/10/2026

Through the SWOT-ICE Experiment, we’ll re-imagine the SWOT satellite mission to track how meltwater moves beneath the Greenland Ice Sheet. We can't wait to dig into this high-risk, high-reward idea! 🛰️ A 2-year postdoc position will be advertised soon. Stay tuned!

DTU Cryosphere group @dtucryo.bsky.social · 01/10/2026

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!

❄️Digging in Antarctic snow pit data❄️ Anna investigated how well snow models can reproduce snowpit observations in Antarctica. Snowpits are very detailed observations of the snowpack, so this study really put the models to the test to see where models perform well and where we need more development❄️

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👇

DTU Space team! Both Kirk and Tabea were mentors for two projects and Anna (in the middel) were a participant. Wanna know more about the project they did? Check out the following posts :)

Not all time was spend coding. Some evenings were also spend enjoying the nice settings. Here you see Kirk, Kristiina (DMI) and Tabea enjoying a nice sunset overlooking the water.
