Group: Summary

   These data describe the d18O of O2, d15N of N2, d18Oatm, and O2/N2 ratios of 
   trapped gases in the Vostok ice core from East Antarctica. The investigator 
   used a mass spectrometer to measure gas concentrations and isotopic 
   compositions. Data extend to approximately 420,000 years ago. Two different 
   age models are included.

   Data are available in tab-delimited ASCII format via ftp.
