Geodetic expedition in Dronning-Maud Land, East Antarctica 2020

Quantifying glacial isostatic adjustment (GIA) in Antarctica is crucial to understand future land and ice- sheet evolution, and to correct estimates of ice-mass change from satellite gravimetry (GRACE). A wide range of GIA models have been developed during recent years adopting different modeling approaches. However, substantial differences between GIA model predictions still remain. Geodetic GNSS (Global Nav- igation Satellite System) observations on bedrock provide direct observables to constrain these models. Within the ongoing project "Investigating glacial-isostatic adjustment on basis of geodetic GNSS obser- vation campaigns in Dronning Maud Land, East Antarctica" funded by the German Research Foundation (DFG), our working group conducted campaign-style GNSS-measurements in western Dronning Maud Land. The talk will give a brief introduction about the scientific background and aims of the project. The main focus will be laid on the procedure of the measurement campaign, to provide inside into logistics of an antarctic expedition and to give impressions of the unique antarctic environment.
