Group: Summary

   Ice thickness and internal layer depth data were collected with a 
   ground-based, ice-penetrating radar study as part of the US International 
   Trans-Antarctic Scientific Expedition (US ITASE) traverse in West Antarctica 
   from 01 November 2001 to 10 January 2003. Longitude, latitude, ice thickness, 
   and depth to a prominent internal reflector were collected at approximately 12 
   m intervals. Ice thickness values are reported for approximately 90% of the 
   traverse, and internal layer depth values are reported for approximately 80% 
   of the traverse. Data are avaialble in ASCII and JPEG formats via FTP.
