In close cooperation with the Alfred-Wegener Institute we will jointly conduct sea ice monitoring campaigns (ca. 2 campaigns per Antarctic summer season with RV Polarstern) using high resolution TerraSAR-X data and in-situ sea ice observations from board Polarstern for ground-truth purposes. The in-situ information will include data of the aboard ice radar, sea ice observations including information of the sea ice types, meteorological data as well as pictures of the surrounding sea ice condition. The team will therefore closly work together with the respective expedition leader of the specific Polarstern cruise as well as the scientists on board. The TSX data will be used for sea ice detection and mapping including the identification of ice conditions, icebergs, ice limits and ice floes areas. In addition, the satellite data will also be used by different working groups on board in order to plan the exact position of their biological, geological and oceanographic stations depending on the current ice situation and also to post-process these data after the respective expedition with repsect to their own scientific work.

The TSX data will mainly be acquired in the near-real time mode. DLR’S GARS O’Higgins station will serve as receiving and processing platform. In addition, the campaigns are designated as test and validation campaigns for further developments and tests of the GARS NRT processing chain, which is operational since 2016.
