The overarching objective of this activity is to explore the potential of GOCE to improve lithospheric modelling over Antarctica, to reduce uncertainties in bedrock topography and to study the implication on GIA modelling based on the derived information. This ismotivated by recent scientific developments, applications and new products that have emerged from ESA’s GOCE mission. In particular,a new data set, provided through the GOCE+ Theme 2 activity (Bouman et al 2014), should enable geophysical application and modelling over Antarctica with the goal to better understand and model the Earth’s interior and its dynamic processes, contributing to new insights into the geodynamics associated with the lithosphere, mantle composition and rheology. This activity shall investigate the potential to determine bedrock topography of the grounded part of the ice sheet with high spatial resolution and accuracy. Furthermore, the activity shall determine – with additional geophysical data and information – the thermal structure or composition of the upper mantle, and hereby to link crust and upper mantle. This will in turn allow to study Earth’s rebound (glacial isostatic adjustment, GIA) over Antarctica from the several kilometre thick ice sheets that covered Antarctica.
