Abstract

The analysis of the Recovery Glacier data set demonstrated the excellent quality of synthetic aperture radar interferometry (InSAR) data available from the Radarsat Antarctic Mapping Mission and its application to glacier dynamics. Phase coherence was high over most highly dynamic area even though the temporal baseline is 24 days. The coherence image enhanced subtle ice sheet topography and indicated the location of shear margins and the grounding line. A radar line-of site ice velocity map identified a large region of slow moving ice that drains the Shackelton Range. Longitudinal strain rates along a flow line within the main ice stream were calculated directly from the wrapped phase.
