d15N & d18O of air in the WAIS Divide ice core

Entry ID: severinghaus_0538657

[ Update this Record ]

Summary

Abstract: Major gas components of air data set, containing d15N, d18O of O2, dO2/N2, and dAr/N2 from the WAIS Divide ice core at high resolution. These data are used to constrain surface temperature, biosphere oxygen cycling, and firn thickness through the past >60 kyr.
