Concentration and Isotopic Composition of O2 and N2 in Trapped Gases of the Vostok Ice Core
Entry ID:
NSIDC-0107
Summary
Abstract:
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.
