Group: Summary

   Snow accumulation rates typically show high variability over short distances. 
   This data set contains accumulation rates using ground-penetrating radar (GPR) 
   to detect isochronal layers in the firn in West Antarctica. These layers were 
   then dated using results from ice core analyses. These data show that 
   accumulation rates along this profile have decreased in recent decades. The 
   radar profile extends between two ice core sites taken along one of the 
   US-ITASE traverse routes.

   Data are available via FTP in both ASCII and Excel formats.
