Concentration and Isotopic Composition of O2 and N2 in Trapped Gases of the Vostok Ice Core [NSIDC-0107]
These data describe the d18O of O2, d15N of N2, d18Oatm, and O2/N2 ratios of trapped gases in the Vostok ice core from East Antarctica. The investigator used a mass spectrometer to measure gas concentrations ...

Carbon-Isotopic Composition of Atmospheric CO2 since the Last Glacial Maximum [NSIDC-0108]
These data describe the concentration and carbon-isotopic composition (d13CO2) of atmospheric CO2 from air trapped in ice between 27,000 and 1,300 years before present from Taylor Dome, Antarctica. ...

Gases in Firn Air and Shallow Ice at the Proposed WAIS Drilling Site [saltzman_0440602]
These data are trace gas measurements of air extracted from ice core samples from the West Antarctic Ice Sheet Divide A core (WAIS-D 05A). This core was dry-drilled at the WAIS site during the 2005-2006 ...

Analysis of Siple Dome Ice Core: Carbonyl Sulfide (COS), Methyl Chloride (CH3Cl), and Methyl Bromide (CH3Br) [NSIDC-0279]
This data set is part of the WAISCORES (West Antarctic Ice Sheet cores) project, research funded by the National Science Foundation (NSF) and designed to improve understanding of how the West Antarctic ...

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) ...

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Gas ratios in air withdrawn from polar firn (snowpack) show systematic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 ...

7.
Neon and other noble gas measurements in ice core samples from Vostok and Megadunes [severinghaus_0230448]
Neon/argon ratios in ice core samples from three sites: GISP2, Greenland, and
Vostok and Megadunes, Antarctica. These samples show that neon is not
preserved in ice core samples, but ...

8.
The concentration and isotopic composition of O2, N2, and Ar in trapped gases of the Vostok ice core (reanalysis) [Vostok_gases_O2_N2_Ar]
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 ...
