In this example GOCE gravity gradients were used  to investigate the thermal and compositional structure of the Antarctic lithosphere. The results will be compared with the global reference model established in 3D Earth. We will also further exploit the new airborne compilation ADMAP2.0 to fill the polar map present in satellite data.

Our new constraints on the Antarctic lithosphere will feed into enhanced models of Glacial Isostatic Adjustment (GIA), one of the most significant uncertainties when assessing present-day ice sheet mass change from satellite studies.
