Group: Summary

   This data set contains sub-annually resolved ice core chemistry data from 
   various sites on the Antarctic Ice Sheet during the US International 
   Trans-Antarctic Scientific Expedition (US ITASE) deployments. Researchers 
   conducted experiments approximately every 30 - 300 km looking for clues 
   representing climatic conditions over the past 200-1000+ years. Ice cores 
   obtained for the glaciochemical component of the US ITASE research were 
   analyzed for soluble major ion content and in some cases trace elements. 
   Extreme events, such as volcanic eruptions, provide absolute age horizons 
   within each core that are easily identified in chemical profiles. Our chemical 
   analysis is also useful for quantifying anthropogenic impact, biogeochemical 
   cycling, and for reconstructing past atmospheric circulation patterns.
