NSIDC-0509 Todd Sowers 20120419 Methane Concentrations from the WAIS Divide Ice Core (WDC06A), 60 to 11,300 ybp Boulder, Colorado USA NSIDC: National Snow and Ice Data Center http://nsidc.org/data/nsidc-0509.html http://dx.doi.org/10.7265/N5J1013R This data set contains a high-resolution history of atmospheric methane (CH4) concentrations in parts per billion (ppb) from approximately 60 to 11,300 years before present (ybp), obtained in 2010 from the West Antarctic Ice Sheet (WAIS) Divide Ice Core WDC06A. Gas age is derived from the WDC06A-5 ice age scale.
