Group: Summary

   This data set consists of Gas-isotopic data from the Siple Dome and and 
   Greenland Ice Sheet Project 2 (GISP2) ice cores covering roughly the last 
   100,000 years (100 ka), consisting of d15N (15N/14N) of N2, d18O (18O/16O) of 
   O2, dO2/N2, and dAr/N2. Derived parameters include d18Oatm, d15N, dO2/N2, and 
   dAr/N2. 

   Data are available via FTP as ASCII text files (.txt) and Microsoft Excel 
   files (.xls).
