Samples were reanalyzed from the Vostok ice core for the O2/N2/Ar ratio, and
the isotopic composition of O2 and N2, at approximately 1 kyr resolution
between 110 -400 ka. This work defined the d18O ...
This data set contains results from a study of the triple isotope composition
of atmospheric O2, obtained by analysis of the GISP2 and Siple Dome ice cores.
Results are expressed as D17O, where
