Group: Summary

   This data set consists of electron microprobe geochemical analyses of glass 
   shards sampled from Siple Dome and Taylor Dome ice cores during the 1999-2000 
   field season. Geochemical data are in tab-delimited ASCII and Excel formats. 
   Backscattered electron images of tephra samples are in TIFF format. Data are 
   available via ftp.
