Europe's Goce gravity satellite probes Earth's mantle
Europe's Goce gravity satellite has provided striking new visualisations of the Earth's deep interior.
Its gravity data has enabled variations in the density of rock to be traced up to more than 2,000km below the surface.
The maps, published by the journal Nature Geoscience, helping to reveal how material moves up and down, driving a range of geological phenomena.
These include subduction zones, where the great tectonic slabs covering the Earth's surface dive under one another.
