Group: Summary

   This data set includes stable isotope measurements from snow pits, firn, and 
   ice cores collected by the the US component of the International 
   Trans-Antarctic Scientific Expedition ( ITASE). The ITASE program aims to 
   collect and interpret a continental-wide array of environmental parameters 
   assembled through the coordinated efforts of scientists from several nations.

   These data were collected between 1999 and 2007. The data have been compiled 
   into single files for each sampling site, though in some cases a file contains 
   data from more than one ice core or snow pit. Each file in the data set 
   includes deuterium/hydrogen (δD) and/or 18-oxygen/16-oxygen (δ18O) 
   ratios, depths, and in some cases ice age or other information. Further 
   details regarding the data are provided in each data file. Data are available 
   via FTP in ASCII text format (.txt). Data were collected during five Antarctic 
   field seasons from 1999 to 2007. Data from 1999 to 2002 are currently 
   available. Data from 2003 to 2007 will be added in the future.
