Group: Summary

   This data set includes ice flow velocities and strain configurations, from GPS 
   measurements on the West Antarctic Ice Sheet (WAIS) Divide. Ninety markers 
   installed in the firn were measured during two consecutive field seasons 
   running from 2005-2006 and 2006-2007. The markers were located in 150 by 60 km 
   area, with smaller clusters of five markers located within about 10 km of each 
   other. Consecutive GPS measurements were used to derive velocity for each 
   marker. Strain configurations were estimated by differentiating a linear fit 
   of the data at each marker cluster. 

   Data are available via FTP as ASCII text (.txt ) files in comma separated 
   value format.
