Group: Summary

   Ice surface elevation and ice thickness data are available for a portion of 
   the West Antarctic Ice Sheet.  The investigators utilized a laser altimeter 
   and ice-penetrating radar mounted to a Twin Otter aircraft to survey the ice 
   sheet. Ice surface elevations and ice thickness data, derived from laser 
   altimetry and radar sounding results, are available in ASCII format via ftp.

   These data are a result of the Corridor Aerogeophysics of the Southeastern 
   Ross Transect Zone (CASERTZ) experiments of the 1990s. The CASERTZ geophysical 
   surveys were aimed at understanding geological controls on ice streams of the 
   West Antarctic Ice Sheet, ultimately to help assess the potential for ice 
   sheet collapse. Blankenship et al. (2001) used ice surface elevations and ice 
   thicknesses (reported here) to calculate driving stresses across the ice sheet 
   and thus to identify regions of rapid basal movement by ice streams.
