Group: Summary

   The data include methane data from the Greenland Ice Sheet Project 2 (GISP2) B 
   & D Cores. Gas ages were calculated according to the methods described in 
   Brook et al. 1996, and are subject to change.  Ice ages were calculated by by 
   linear interpolation from the Meese et al. timescale.
