Satellites reveal hidden ice canyons
CPOM’s Noel Gourmelen explains how ESA’s Sentinel-1 and CryoSat missions have shed light on the huge canyons hidden within the Antarctic ice shelf in a new ESA article, summarised in the video below.

Update on the Larsen-C iceberg breakaway
The largest remaining ice shelf on the Antarctic Peninsula lost 10% of its area when an iceberg four times the size of London broke free earlier this month. Since the 12 July 2017 breakaway, CPOM’s Dr Anna Hogg and Dr Hilmar Gudmundsson,…

Giant iceberg in the making at Larsen-C
ESA satellites are monitoring a deep crack that continues to cut across the Larsen C ice shelf. When it eventually gives way, it will create one of the largest icebergs on record. Sentinel-1 now shows the crack in the ice…

Antarctic Peninsula ice more stable than thought
Glacier flow at the southern Antarctic Peninsula has increased since the 1990s, but a new study has found the change to be only a third of what was recently reported. An international team of researchers, led by CPOM, is the…

Sentinel-1 monitors growing crack in Larsen-C
Radar mission Sentinel-1 continues to monitor the growing crack in Antarctica’s Larsen-C ice shelf, which is expected to produce a massive iceberg Two Sentinel-1 radar images from 7 and 14 April 2017 have been combined to reveal the growing…

CryoSat reveals Antarctica in 3D
Around 250 million measurements taken by ESA’s CryoSat mission over the last six years have been used to create a unique 3D view of Antarctica, offering a snapshot of the undulating surface of this vast ice sheet. CryoSat’s radar altimeter…

PhD opportunity: Greenland/Antarctic ice sheet mass balance and regional variability in sea level rise
CPOM is seeking an excellent PhD candidate to work at the interface of climate and space science. Using Earth Observation data acquired by satellites such as CryoSat-2, the European Space Agency’s mission dedicated to monitoring the polar regions, you…

Satellites track variations in retreat of West Antarctic glaciers
An almost 25-year long record of elevation change of some of Antarctica’s fastest flowing and receding glaciers reveals important differences in the timing of retreat between single glaciers and the pace by which the ice loss spreads to Antarctica’s interior,…

Pine Island Glacier on Sentinel-1A’s radar
This image combining two scans by Sentinel-1A’s radar shows that parts of the Pine Island glacier flowed about 100 m (in pink) between 3 March and 15 March 2015. Light blue represents stable ice on either side of the stream….
