Abstract :
In this study, we observed the motion of the Campbell glacier near the Terra Nova Bay by using interferograms from synthetic aperture radar onboard COSMO-SkyMED satellites and from a GB-SAR field experiment. The glacier and ice tongue showed fast motion in winter as well as summer season. The glacier observed in the COSMO-SkyMED interferograms showed over 30 cm motion in a single day. GB-SAR interferogram with 11-hour difference indicated about 8 cm displacement in the radar direction. The combination of COSMO-SkyMED and GB-SAR interferometry has shown a very promising result to extend the research to other fast-flowing glaciers.
