Old enough to recognize this as a data center

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 🌍🧊

Hey Folks! 👋 Please share that our Department of Glaciology & Climate is hiring a new technician (full time/permanent) to support our ice-sheet monitoring projects. Application deadline 3 June 2026 ⤵️ candidate.hr-manager.net/ApplicationI...

📢 Want to hear more about the EO-based activities of our group? Meet us at #EGU26 @egu.eu next week, we'll be around with the following presentations and sessions:

Introducing #PRODEM‑Xtract: An open‑source tool providing 32 m‑resolution annual ice thickness along Greenland Ice Sheet flux gates ❄️ Applied to major Greenland glaciers, it reveals previously unresolved dynamics, thereby improving estimates of solid ice discharge 🧊 Link: tinyurl.com/PRODEM-Xtract

@louisesandbergs.bsky.social and @nataliahavelund.bsky.social attended the CCI colocation meeting last week. There were many important discussions on the future of the programme. Thanks for having us!

Big congrats to Anna for defending her PhD on surface mass balance using EO data 👏🎓✨ And of course, the celebration included a proper cake with P H D spelled out on top 🎂 #PhD #PhDDefense #SurfaceMassBalance #EarthObservation #Cryosphere

🚨 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

❄️Theory and practice❄️ (Part 2) This week in Sisimiut we continue our Extreme Climate and Physical Nature course on the Arctic Semester by diving into snow physics. After covering the theory, students headed into the field to explore the snowpack firsthand. #CryoTeaching #ArcticDTU #SnowScien

David Attenborough [whispering]: “As the predators close in on their helpless prey, we can only watch in silent horror, for it is not man’s role to interfere in the hierarchy of nature.”

❄️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. #CryoTeaching #ArcticDTU

Arctic DTU has moved to a new campus building in Sisimiut. Saw it for the first time today. It is very…. Green! 🤩💚

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/... ❄️🧊

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition. Which just makes me want to share it again: www.nature.com/articles/d41...

🛰️BIG NEWS! NASA has selected a @ucsandiego.bsky.social led satellite mission for the Earth System Explorers program. Led by Scripps Oceanography glaciologist @helen-amanda.bsky.social, Earth Dynamics Geodetic Explorer (EDGE) is one of two next-generation satellite missions selected. 🧵⤵️

Most people are worried about climate change - but most don't hear or talk about regularly. That's why I started my free newsletter Talking Climate. Every week I share good news, not so good news, and what people can do. If you aren't a reader yet, see below. I have 6 different ways to subscribe!

🍾🥂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! 🏝️

Heading South But not for the warmth.. Tomorrow I'm taking the first stage of the journey to Antarctica, ironically enough though, I'm heading south by first heading north, to Oslo, where the Norwegian Polar Institute have organised an almost direct flight from Oslo to Troll station with a short…

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

A message much better stated than I could say it, but which I try to give to ECRs I work with. There are seasons in research and sometimes it is harvest time, but sometimes the seeds are just sitting in the ground resting and waiting for Spring. www.joanwestenberg.com/the-harvest-...

We 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!
