The GISP2 gas age time scale is from Brook et al., Rapid changes in atmospheric methane during the past 110,000 years, Science, 273, 1087-1091.
The Taylor Dome gas age time scale was derived by correlating the GISP2 and Taylor Dome methane records.This ice core data is archived at the World Data Center for Paleoclimatology and is available through the Ice Core Data Gateway. The data includes methane data from the Greenland Ice Sheet Project 2 (GISP2). GISP2 is an ice core project that drilled through the Greenland ice sheet and 1.55 meters into bedrock. The ice core is 3053.44 meters in depth, the deepest ice core recovered in the world at the time. The ice core was completed in 1993 after five years of drilling.
Methane concentrations were determined by GC-FID using standards calibrated by NOAA CMDL. The gas age time scales and analytical techniques are described in further detail in the publication.https://nsidc.org/data/NSIDC-0360/versions/1GET DATAftp://ftp.ncdc.noaa.gov/pub/data/paleo/icecore/greenland/summit/gisp2/gases/gisp2_ch4_highres.txtGet External DataPROJECT HOME PAGEhttp://www.ncdc.noaa.gov/paleo/data.htmlNOAA NCDC World Data Center for PaleoclimatologyCEOS IDN DIFVERSION 9.92008-12-162019-09-27NSIDCVersion SummaryNSIDCMinor VersionNSIDCCurrent Version1NSIDCLevel of ServiceNo Data AccessNSIDCFull Dataset CitationPlease contact the data provider for the citation for these data.NSIDCRetiredfalse
