Project description The aim of this research project is to investigate changes in height, flow rate and deformation in the Greenland ice sheet as a function of climate change. The long-term research project began in 1991, with 10 measuring campaigns conducted on the Greenland ice sheet in the 17 years to 2008. The original measuring area (Swiss Camp) has been supplemented by a second measuring area (ST2) since 2004. Analysis of the data gathered shows a significant acceleration in the loss of ice mass, but surprisingly also confirms an acceleration in flow rate. The second observation in particular requires further examination. The dependence of measuring results on climate change is therefore being jointly investigated with colleagues from the University of Colorado Boulder, who have also provided access to their weather stations. Comparisons with flow rate models are also being carried out in cooperation with the University of Colorado Boulder. Comparisons focusing on energy and mass balance are also planned, in this case in cooperation with Cambridge University. Satellite measurements will be validated with the aid of comparisons against results delivered by the ICESat/USA and CryoSat/ESA. The next measuring campaign is due to start in the summer of 2011.
