Major collaborations

CPOM’s major collaborations are described below.  We also provide details of all our current and recent initiatives, as well as older projects.


Three years of measurements from CryoSat show that the Antarctic Ice Sheet was, as of 2014, losing 159 billion tonnes of ice each year - enough to raise global sea levels by 0.45 mm per year. Credit:CPOM/ESA

IMBIE (the Ice Sheet Mass Balance Inter-Comparison Exercise) is an international collaboration providing improved estimates of the ice sheet contribution to sea level rise, and ice sheet mass balance, by combining gravimetry, altimetry and the mass budget method.



ISMIP6 (the Ice Sheet Model Intercomparison for the Coupled Model Intercomparison Project, CMIP6) brings together international ice sheet models and coupled ice sheet-climate models to fully explore the sea level rise contribution from the Greenland and Antarctic ice sheets.



iSTAR (the NERC Ice Sheet Stability Programme) is improving understanding of changes to the West Antarctic Ice Sheet where the greatest rates of ice loss have been observed, including the Pine Island, Thwaites and Union Glaciers.

TEA-COSI is a major collaboration aiming to deliver substantial improvements in our understanding of key Arctic ocean and sea ice processes and their impact on the Arctic and wider climate system, and ultimately improve capability to predict changes in the Arctic.
