   Description: 
      Abstract:
         This dataset contains ground-based, co-polarized radar data collected using 
         pulse-modulated 60 MHz and 179 MHz radar at 19 sites around a deep ice coring 
         site near the Ross and Amundsen flow divide of West Antarctic Ice Sheet (WAIS 
         Divide).  At each site, the radar data were collected at 12 orientations of 
         the radar polarization plane for three radar pulse widths: 250 nsec, 500 nsec, 
         and 1000 nsec. Useful signals were received from depths roughly between 200 m 
         and 2000 m.  Ice flow velocities and strain configurations were measured at 
         most of these radar survey sites, and these ice motion data are also provided 
         at NSIDC (GPS-Measured Ice Velocities and Strain Data from the Ross and 
         Amundsen Sea Ice Flow Divide, West Antarctica).

         Data are available via FTP in MATLAB (.mat) format.
