Abstract

Ice motion vector fields derived from satellite images are analysed for one region in the central part of the Weddell Sea, Antarctica. Taking overlapping ERS-1 SAR and NOAA-AVHRR data the analysis could be made for approximately the same time period. Whereas mean values for velocity and direction are consistent for each sensor, the shear of the ice pack is much higher for the AVHRR frames. Short time variations due to changing surface wind conditions are clearly visible in the AVHRR data
