The Esa's Goce (Gravity field and steady-state Ocean Circulation Explorer) mission was launched two years ago and provides a Earth's geoid with unprecedented quality and resolution.
The geoid is defined like an equipotential surface. On oceans, the geoid coincides with the mean sea surface, i.e. with a calm ocean surface without tides and currents. It's a reference to measure ocean circulation, sea-level change and ice dynamics.
The precise model of Earth's geoid made by Goce helps to improve our understanding of the ocean dynamic.
