CryoSat goes to sea

28 May 2012

CryoSat was launched in 2010 to measure sea-ice thickness in the Arctic, but data from the Earth-observing satellite have also been exploited for other studies. High-resolution mapping of the topography of the ocean floor is now being added to the ice mission’s repertoire.

Mapping the Moho with GOCE

09 March 2012

The first global high-resolution map of the boundary between Earth's crust and mantle - the Moho - has been produced based on data from ESA's GOCE gravity satellite. Understanding the Moho will offer new clues into the dynamics of Earth's interior.

Updated Mean Sea Level trend

10 June 2009

EUMETSAT Jason-2 data are now routinely used for the continuous monitoring of the global Mean Sea Level (MSL). The figure represents the MSL evolution as measured by altimetry satellites since TOPEX/Poseidon and continued by Jason-1 and now by OSTM/Jason-2. Each point is the result of one 10 days cycle measurement.
