   After processing the raw data as described in the documentation that 
   accompanies the data set, and assuming Gaussian distribution of erros, the 
   total resulting error in ice draft measurements is about 4 cm (Strass, 1998).

Group: Summary

   This data set consists of moored Upward Looking Sonar (ULS) data from 14 
   stations in the Weddell Sea. Parameters in the processed data files are water 
   pressure, water temperature, draft, and a flag to indicate if the instrument 
   is under ice. Raw data files contain additional parameters. These data were 
   contributed by the Alfred Wegener Institute for Polar and Marine Research, 
   Bremerhaven, Germany, in 1999. Data are available via ftp.
