Alaska Satellite Facility
Delivering Remote Sensing Data Since 1991

Mini-MAMM — 2004 and 2007

Subsequent to the 1997 and 2000 missions, two other smaller mappings were made in 2004 and again in 2007. Interferometric pairs were used to compute ice sheet surface velocities during the months of September-December. Velocity products were generated for the Drygalsky Ice Tongue (David Glacier) and the Thwaites and Pine Island Glaciers.

Ohio State University provided the data to the Center for Remote Sensing of Ice Sheets (CReSIS) for the development of models that reliably predict future ice sheet contributions to sea level rise under prescribed changes in climate.

Historical Data for Comparison

The DISP Mosaic (Declassified Intelligence Satellite Photographs) is useful for comparing the extent and internal configuration of the Antarctic ice sheet with current satellite data.
