GOCE producing global maps of ocean currents - Images
ESA's GOCE satellite has been mapping the Earth's geoid since 2009, to further our understanding of the planet's gravity field.

The surface velocity of currents in the ocean can be tracked, and this property, among others, contributes to understanding not only the ocean, but gravity as well.
A better knowledge of Earth's gravity field and its associated geoid will significantly advance our understanding of how the Earth system works. An accurate model of the geoid will advance our understanding global ocean circulation patterns and sea-level rise.
ESA's GOCE mission has been producing dynamic topography maps to better understand the circulation and surface of the ocean. This improves our understanding of the Earth's gravity through the measurements of pressure the water exerts.
