Group: Summary

   This data set measures the radioactive decay of nuclear material from Northern 
   and Southern hemisphere nuclear testing. Firn cores were taken from three 
   locations on Roosevelt Island, an ice dome within the Ross Ice Shelf, and were 
   measured at increasing depth for density in kilograms per cubic meter, and for 
   beta counts per hour per kilogram.

   The data were collected between November and December of 1997. Measurements 
   were taken incrementally down to approximately 17 meters for each of the three 
   cores. Data are available in text format via ftp.
