Firn Air Inert Gas and Oxygen Observations from Siple Dome, 1996, and the South Pole, 2001

Entry ID: NSIDC-0290

[ Update this Record ]

Summary

Abstract: This data set includes gas ratios in polar firn air: O2/N2, 15N/14N, 40Ar/N2, 40Ar/36Ar, 40Ar/38Ar, 84Kr/36Ar, 132Xe/36Ar, and 22Ne/36Ar. Investigators sampled air from the permeable snowpack (firn) layer at two sites: Siple Dome, Antarctica in 1996 and at the South Pole in 2001. They observed and modeled the processes of gravitational settling, thermal fractionation, and preferential exclusion of ...
