ESA's GOCE gravity satellite may be in its final weeks in orbit around Earth, but some of the most exciting scientific analysis of the mission's data is only just starting.

Carrying the first 3D gravity gradiometer in space and orbiting lower than any other research satellite, GOCE has spent more than four years measuring variations in Earth's gravity with unrivalled precision.

The result is the most accurate model of the 'geoid' ever produced, which is being used to understand ocean circulation, sea level, ice dynamics and Earth's interior.
