Concentration and Isotopic Composition of O2 and N2 in Trapped Gases of the Vostok Ice Core
Listed in NASA Earthdata CMR
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.
Description
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.
