   Methane data from Brook et al., On the origin and timing of rapid changes in 
   atmospheric methane during the last glacial period,Global Biogeochemical 
   Cycles, 14(2), 559-572.					

   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.

Group: Summary

   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.
