We report on results from spaceborne velocity and topography measurements of the Drygalski glacier, Antarctic Peninsula. For our analysis we use a time series of TerraSAR-X data acquired between 2007 and 2010 which enables us to perform an error analysis and to determine higher order velocity parameters such as acceleration. Our estimated accuracy for velocity estimation is on the order of 2 cm/day...
An incoherent correlation approach is used to derive ice motion fields for outlet glaciers through the Transantarctic Mountains, Antarctica. High-resolution repeat-pass, left-looking-mode TerraSAR-X data from 2009 were analyzed. Detailed ice velocity patterns on the Nimrod glacier basin and Starshot glacier are presented.
