Earth's Gravity Revealed in Unprecedented Detail

Earth's Gravity Revealed in Unprecedented Detail

31 March 2011
After just two years in orbit, ESA's GOCE satellite has gathered enough data to map Earth's gravity with unrivalled precision. Scientists now have access to the most accurate model of the 'geoid' ever produced to further our understanding of how Earth works.

The new geoid was unveiled today at the Fourth International GOCE User Workshop hosted at the Technische Universit√§t M√ľnchen in Munich, Germany. Media representatives and scientists from around the world have been treated to the best view yet of global gravity.

The geoid is the surface of an ideal global ocean in the absence of tides and currents, shaped only by gravity. It is a crucial reference for measuring ocean circulation, sea-level change and ice dynamics – all affected by climate change.
