Satellite radar interferometry (SRI) provides a sensitive means of monitoring the flow velocities and grounding-line positions of ice streams, which are indicators of response of the ice sheets to climatic change or internal instability. The detection limit is about 1.5 millimeters for vertical motions and about 4 millimeters for horizontal motions in the radar beam direction. The grounding line, detected by tidal motions where the ice goes afloat, can be mapped at a resolution of ∼0.5… Expand
Antarctic grounding line mapping from differential satellite radar interferometry
[1] The delineation of an ice sheet grounding line, i.e., the transition boundary where ice detaches from the bed and becomes afloat in the ocean, is critical to ice sheet mass budget calculations,Expand
RADARSAT interferometry for Antarctic grounding-zone mapping
Abstract Satellite radar interferometry (SRI) is used to provide new information on grounding zones in areas of the eastern Ross Ice Shelf and the Filchner Ice Shelf, Antarctica. At the times of theExpand

Improvement of Satellite Radar Feature Tracking for Ice Velocity Derivation by Spatial Frequency Filtering
An improvement on the cross-correlation technique is presented that enables independent quality checks and enhances the spatial extent of the derived velocity fields and allows a nonregional culling based on the signal-to-noise ratio of the velocities, with the effect of increasing the coverage of robust velocity estimates.

Measurement of ice-sheet topography using satellite-radar interferometry
Detailed digital elevation models (DEMs) do not exist for much of the Greenland and Antarctic ice sheets. Radar altimetry is at present the primary, in many cases the only, source of topographic dataExpand

Abrupt climatic change related to unstable ice-sheet dynamics: toward a new paradigm
Ice streams are fast currents of ice that drain some 90% of present-day ice sheets, and probably drained a similar percent of ice from former ice sheets. Ice streams may have life cycles akin to, butExpand
