Summary
Abstract: This data set contains methane (CH4) concentration data derived from the
Greenland Ice Sheet Project II (GISP2) ice core. The methane concentration was
measured from trapped gases in in samples from 309 depths in the upper 2810 m
of the GISP2 ice core. The time period extends to 110,000 yBP. The data set
consists of Depth (m), Methane (ppbV) and Gas Age (ka). Data are available in
ASCII format via ftp from the World Data Center for Paleoclimatology.
