Group: Summary

   This data set includes includes high-precision GPS measurements of steel poles 
   within the Allan Hills Main Ice Field, Near Western Ice Field, and extending 
   to the eastern edge of the Middle Western Ice Field, in Antarctica. These data 
   were collected between December 1997 and December 2010. The extended survey 
   period allowed for vertical and horizontal velocities to be calculated with 
   low associated error. Parameters include locations of poles in latitude and 
   longitude, as well as elevation, ice velocity, and accumulation rates.

   Data are available via FTP as ASCII text files in comma separated value (.csv) 
   format. Raw data are also provided as Trimble raw data, compressed in .zip 
   format, and supplementary information is provided in .csv format and portable 
   document format (.pdf).
