Group: Summary

   Researchers gathered data on annual snow layers at Siple Dome, Antarctica, 
   using borehole optical stratigraphy. This data set contains annual layer 
   depths and firn optical brightness. The brightness log is a record of 
   reflectivity of the firn, and peaks in brightness are interpreted to be 
   fine-grained high-density winter snow, as part of the wind slab depth-hoar 
   couplet. 

   Data are available via FTP in ASCII text (.txt) format
