1. Firn Air Isotope and Temperature Measurements from Siple Dome and South Pole [NSIDC-0098]
This data set includes d15N, d18O/2, dO2/N2/4, d40Ar/4, d38/Ar/2, d84Kr/48, and d132Xe/96 values for air drawn from the top 15 to 50 m of firn at the South Pole (summer and winter 1998) and a site ...


2. Firn Air Inert Gas and Oxygen Observations from Siple Dome, 1996, and the South Pole, 2001 [NSIDC-0290]
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) ...


3. Fractionation of gases in polar ice during bubble close-off: firn air Ne, Kr and Xe observations [severinghaus_nsidc0290]
Gas ratios in air withdrawn from polar firn (snowpack) show systematic enrichments of Ne/N2, O2/N2 and Ar/N2, in the firn?ice transition region where bubbles are closing off. Air from ...


4. Gases in Firn Air and Shallow Ice at the Proposed WAIS Divide Drilling Site [battle_0440509]
This award supports a project to measure the elemental and isotopic composition of firn air and occluded air in shallow boreholes and ice cores from the WAIS Divide site, the location of a deep ice-coring ...
