Group: Summary

   This data set contains methane measurements made in trapped air in the 
   Holocene sections of two ice cores: the Siple Dome ice core in Antarctica, and 
   the Greenland Ice Sheet Project 2 (GISP2) ice core in Greenland. The 
   measurements were made at Oregon State University between 2007 and 2009. 
   Measurements were made relative to the NOAA04 methane concentration scale 
   using a working standard internally calibrated to NOAA certified air 
   standards. Concentrations are corrected for gravitational fractionation and 
   solubility effects in the melt-refreeze extraction. Data are available via FTP 
   in Microsoft Excel (.xls) format.
