BBC : The European Space Agency’s Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) mapped Earth’s gravitational field from 2009 to 2013. Now that map is being used to look for clues about the internal structure of Earth’s crust. Subtle variations in gravitation can be evaluated to find the borders between rock formations and areas where the crust is thinnest, both of which are potential locations for geothermal activity. Such data have been used by geothermal prospectors before, but never at a global scale nor with the resolution that GOCE has provided.
