Group: Summary

   This data set consists of upward looking sonar draft data collected by 
   submarines in the Arctic Ocean.  It includes data from both U.S. Navy and 
   Royal Navy submarines. Maps showing submarine tracks are  available.  Data are 
   provided as ice draft profiles and as statistics derived from the profile 
   data. Statistics files include information concerning ice draft 
   characteristics, keels, level ice, leads, un- deformed and deformed ice.  Data 
   from the U.S. Navy's Digital Ice Profiling System (DIPS) have been  
   interpolated and processed for release as unclassified data at the U.S. Army's 
   Cold Regions Research  and Engineering Laboratory (CRREL) in Hanover, New 
   Hampshire. Data from the analog draft recording  system were digitized and 
   then processed by the Polar Science Center, Applied Physics Laboratory,  
   University of Washington.   Data from British submarines were provided by the 
   Scott Polar Research  Institute, University of Cambridge. All data sources 
   used similar processing methods in order to ensure  a consistent data set. 

   Access to the Submarine Upward Looking Sonar Ice Draft Profile Data and 
   Statistics data set is  unrestricted, but users are encouraged to register for 
   the data. Registered users will receive e-mail notification about any product 
   changes.
