The use of satellite data in the detailed study and precise measurement of the Earth's geoid in order to improve our understanding both of the Earth's interior, and dynamic topography of the world's oceans.
Earth's gravity scarred by earthquake
03 December 2013
ESA's GOCE satellite has revealed that the devastating Japanese earthquake of 2011 left its mark in Earth's gravity - yet another example of this extraordinary mission surpassing its original scope.
GOCE mapped Earth's gravity with unrivalled precision for over four years, but nobody really expected the data to show changes over time.
Now, careful analysis shows the effects of the 9.0 earthquake that struck east of Japan's Honshu Island on 11 March 2011 are clearly visible in GOCE's gravity data.
