1. 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 ...


2. Antarctic Ice Cores: Methyl Chloride and Methyl Bromide [NSIDC-0313]
This data set is an analysis of methyl chloride (CH3Cl) and methyl bromide (CH3Br) in Antarctic ice core samples. Investigators reported mixing ratios of methyl chloride gas extracted from samples ...


3. Atmospheric CO2 and Climate: Byrd Ice Core, Antarctica [NSIDC-0314]
Reconstructions of ancient atmospheric CO2 variations help us better understand how the global carbon cycle and climate are linked. Here we compare CO2 variations on millennial time scales between ...


4. Atmospheric CO2 and Climate: Taylor Dome Ice Core, Antarctica [NSIDC-0315]
Using new and existing ice core CO2 data from 65 - 30 ka BP a new chronology for Taylor Dome ice core CO2 is established and synchronized with Greenland ice core records to study how high latitude ...


5. Atmospheric Mixing Ratios of Hydroperoxides above the West Antarctic Ice Sheet [NSIDC-0394]
This data set contains atmospheric mixing ratios of hydrogen peroxide and methylhydroperoxide at 21 sites on the West Antarctic Ice Sheet (WAIS) were obtained from 2000 to 2003 during the US International ...


6. Collaborative Research: Replicate Coring at WAIS Divide to Obtain Additional Samples at Events of High Scientific Interest [severinghaus_1043421]
This award supports a project to obtain samples of ice in selected intervals for replication and verification of the validity and spatial representativeness of key results in the WAIS Divide ice core, ...


7. 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, ...


8. 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 ...


9. 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 ...


10. Gases in Firn Air and Shallow Ice at the WAIS Drilling Site, Antarctica [NSIDC-0412]
This data set contains trace gas measurements of air extracted from ice core samples from the West Antarctic Ice Sheet Divide A core (WAIS-D 05A). The WAIS A core was dry-drilled at the WAIS site ...


11. Methane Concentration and Chronology from the WAIS Divide Ice Core (WDC05A) [NSIDC-0493]
This data set provides a high-precision and high-resolution record of atmospheric methane from the West Antarctic Ice Sheet (WAIS) Divide ice core WDC05A, spanning the years 1000 to 1800 C.E. The ...


12. Methane Measurements from the GISP2 and Siple Dome Ice Cores [NSIDC-0440]
This data set contains methane measurements made in trapped air in the Holocene sections of two ice cores: the Siple Dome ice core in Antarctica, and the Greenland Ice Sheet Project 2 (GISP2) ice ...


13. Methyl Chloride Measurements from the Siple Dome A Deep Core, Antarctica [NSIDC-0356]
This data set is an analysis of methyl chloride concentration measured in air extracted from ice core samples from the Siple Dome A deep core in West Antarctica. In total, forty six (46) ice samples, ...


14. Sulfate-Based Volcanic Record from South Pole Ice Core [NSIDC-0215]
This data set contains concentrations of soluble chemical species (ions) within a 120 m ice core retrieved at the South Pole station in 2001. The ice core was dated with annual resolution using annual ...


15. Twenty-Three Century-scale Ice Core Records of Hydrogen Peroxide (H2O2) from West Antarctica [NSIDC-0392]
This data set contains sub-annually resolved concentrations of hydrogen peroxide (H2O2), snow, firn and ice from 23 sites on the West Antarctic Ice Sheet (WAIS. Data were obtained from 2000 to 2003 ...


16. US ITASE Stable Isotope Data, Antarctica [NSIDC-0425]
