Group: Summary

   This data set is part of the West Antarctic Ice Sheet cores (WAISCORES) 
   project, an NSF-funded project to understand the influence of the West 
   Antarctic ice sheet on climate and sea level change. WAISCORES researchers 
   acquired and analyzed ice cores from the Siple Dome, in the Siple Coast 
   region, West Antarctica. Siple Dome ice cores were analyzed for 
   methanesulfonate (MSA) and carbonyl sulfide (OCS). The methanesulfonate 
   analysis was done on cores A-E and a hot water core, and the carbonyl sulfide 
   analysis was done on 11 C cores. Methanesulfonate data include the sample 
   identification number, depth, and methanesulfonate parts per billion (ppb) of 
   each sample. Carbonyl sulfide data include the depth, OCS parts per trillion 
   (ppt) of each sample, percent error, and gas age (years). Data are available 
   via FTP in tab-delimited ASCII text (.dat, .txt) file format.
