| Summary: | Summary The SCAR GPS Campaigns have been carried out under the umbrella of the Scientific Committee on Antarctic Research (SCAR) annually since 1995. In an advanced analysis concept we combine the regional solution from the SCAR network with a homogeneously reprocessed global solution. This combination minimizes inconsistencies in the realiza-tion of the global reference system in Antarctica. The station coordinates and velocities obtained provide an excellent reference for a broad variety of geoscientific applications. In addition, the obtained results contain valuable information for geoscientific investigations, such as plate kinematics, the stability of the Antarctic Plate or vertical deformations due to glacial isostatic processes. We present the status, introduce an advanced analysis concept of the SCAR GPS network and evaluate the derived accuracies. We discuss in detail the geoscientific implications of the obtained results. We provide an outlook on the contribution of the SCAR GPS Campaigns to the IPY project POLENET in Antarctica. |
