Group: Summary

   This data set contains high-resolution logs of dust and microbes measured at 
   the Siple Dome A borehole in Antarctica. The data were obtained using a newly 
   developed optical borehole logger, which fits into a fluid-filled borehole in 
   glacial ice. It can detect dust and microbes in ice out to several meters from 
   the borehole, and measure optical properties of those particles. The data set 
   contains information on depth and optical signal. Data are available via FTP 
   in data file format (.dat).
