Gases in Firn Air and Shallow Ice at the Proposed WAIS Drilling Site contains trace gas measurements from 57 ice core samples from the West Antarctic Ice Sheet Divide A core. The dataset includes mixing ratios for nine trace gas species: ethane, propane, n-butane, carbonyl sulfide, carbon disulfide, methyl chloride, methyl bromide, acetonitrile, and chlorofluorocarbon-12. Analyses were conducted by the University of California, Irvine on samples dry-drilled during the 2005-2006 field season.
Data is labeled as preliminary and unpublished; users should cite the foundational methodology papers (Aydin et al., 2007; 2008) and treat results with appropriate caution, especially for light alkanes and CH3CN.
