There are lakes buried deep beneath the Greenland ice sheet we can’t see called subglacial lakes.
📽️ In this video CPOM's Professor Mal McMillan @lancasteruni.bsky.social explains how researchers working on the GLOBE project aim to track them 👇

In 2025, a CPOM study from Lancaster University investigated the sudden draining of a recently detected lake under the Greenland ice sheet (subglacial lake), using European Space Agency (ESA) and NASA satellite data and 3D simulations from the ArcticDEM project.

In 2024, a study led by CPOM researcher Nitin Ravinder delivered the first measurements of the Greenland Ice Sheet’s changing shape using data from ESA’s CryoSat and NASA’s ICESat-2 ice missions.

The GLAMBIE team (Glacier Mass Balance Intercomparison Exercise), co-led by Prof Noel Gourmelen, produced updated figures on glacier loss showing that from 2000 – 2023 glaciers across the globe lost 6542 billion tonnes of ice, contributing 18 mm to global sea level rise.

The IMBIE (Ice Sheet Mass Balance Inter-Comparison Exercise) team, led by Dr Inès Otosaka, have reconciled three decades of satellite measurements to provide the world’s most authoritative estimates of ice sheet mass balance and sea level rise contributions.

Using using data from ESA and NASA satellite missions, including CryoSat-2, and Copernicus, research led by CPOM's Dr Tom Slater found that the Earth was losing more than a trillion tonnes of ice a year.

🛰️Sunday is #HumanSpaceFlightDay - 65 years since humans first reached orbit.
Satellite technology has transformed what we know about the cryosphere.
Scroll down to read about just some of the CPOM science the space age made possible in recent years 👇

A routine calibration by Copernicus Sentinel‑2 captured this image of the Moon.
And now, with Artemis II on its way there, Europe is part of the journey — powering Orion with the European Service Module and supporting the mission from the ground across the continent.
One week to go until the 5th ECMWF-ESA Machine Learning workshop in Bologna, Italy.
The workshop takes place from 13-17 April and will explore the opportunities and challenges of using ML for Earth Observation and Prediction (ESOP).

🌍It's #WorldHealthDay and the WHO is calling on everyone to celebrate the power of scientific collaboration to protect the health of people, animals, plants, and the planet.
🧊Understanding the cryosphere and how it is changing is a vital part of that story.

CRISTAL, ESA's next polar altimeter launching in 2027 will have a a 256 m window. The research provides evidence that wider windows significantly improve performance over dynamic ice sheet margins.
Implementing a 240 m window, like ESA's CryoSat-2 Earth Explorer mission, achieves near-complete coverage, even over complex terrain.
Analysis of 8 million+ radar echoes showed that Sentinel-3's 60 m measurement window captured 89.2% of the maximum topographic signal that could be recorded within its range window.

For Dr Tom Slater (@northumbriauni.bsky.social) the journey into polar science was far from linear.
Always interested in climate science, Tom hadn't got the A-levels needed to pursue it at degree level.
But there was another route 👇
