Gases in Firn Air and Shallow Ice at the WAIS Drilling Site, Antarctica

View Catalog Page

Entry ID

NSIDC-0412

Summary

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 during the 2005-2006 Antarctic field season. Data include trace gas species including ethane (C2H6), propane (C3H8), n-butane (n-C4H10), carbonyl sulfide (COS), carbon disulfide (CS2), methyl chloride (CH3Cl), methyl bromide (CH3Br), acetonitrile (CH3CN), and chlorofluorocarbon-12 (CFC-12), for 57 ice core samples. The data are available via FTP in Microsoft Excel (.xls) file format.
