The concentration and isotopic composition of O2, N2, and Ar in trapped gases of the Vostok ice core (reanalysis)
Entry ID: Vostok_gases_O2_N2_Ar

[ Update this Record ]

Summary
Abstract: 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 curve of paleoatmospheric O2
at a much higher resolution than was previously available. The O2/N2 ratio was
more highly variable than in the original, lower resolution Vostok record.
