Talk about Diploma thesis: "Surface velocities in the hinterland of the Neumayer III station (Antarctica) derived from SAR-interferometry"
Surface velocities of polar ice are an important input parameter for mass flux calculations and ice-sheet modeling. As on-site measurements in remote areas are sparse, satellite-based measurements have to be used to obtain area-wide surface velocities. Synthetic Aperture Radar (SAR) data from variou...
