Abstract

Observations of ice flow velocity with TerraSAR-X were carried out over main outlet glaciers of the Southern Patagonia Icefield (SPI) since 2008 by means of amplitude correlation technique. Velocity data are required to estimate the ice export due to calving. Furthermore we compare ice elevation from a TanDEM-X DEM of 2011 and from an SRTM DEM of 2000 in order to quantify the volume loss of these glaciers over the last decade. Results are shown for three glaciers of the central section of SPI, exhibiting distinct differences in the observed trends for surface topography and ice velocity.
