Having collected 12_months of gravity data, ESA磗 GOCE mission has delivered the most accurate model of the 磄eoid?ever produced, which will be used to further our understanding of how Earth works. 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.brRestrictions:
