Group: Summary

   This data set provides a high-precision and high-resolution record of 
   atmospheric methane from the West Antarctic Ice Sheet (WAIS) Divide ice core 
   WDC05A, spanning the years 1000 to 1800 C.E. The data include methane (CH4) 
   concentration measurements and ice age chronology. Methane concentration data 
   include mean sample depth, gas age, mean concentration, and concentrations 
   from individual measurements, at a temporal resolution of approximately nine 
   years. Ice chronology data include depth and ice age.

   Data are available via FTP, in Microsoft Excel (.xlsx) format.
