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 ... View entire text
