Group: Summary

    The Science Ice Exercise (SCICEX) program is a collaboration between the U.S. 
   Navy and the marine research community to utilize nuclear-powered submarines 
   for the study of the Arctic Ocean. Unlike surface ships, submarines have the 
   unique and valuable ability to operate and take measurements regardless of sea 
   ice cover and weather conditions. The goal of the program is to acquire 
   comprehensive data about Arctic sea ice, water properties, and bathymetry.

   SCICEX is important because it adds critical pieces to the overall information 
   needed to analyze sea ice and ocean dynamics - ice thickness and bathymetry 
   data in particular but also chemical, biological, and physical oceanographic 
   data. With the success of the initial project in 1993, the U.S. Navy and the 
   National Science Foundation (NSF) signed a Memorandum of Agreement (MOA) in 
   1994 that called for five more dedicated SCICEX missions. The dedicated SCICEX 
   cruises occurred in 1995, 1996, 1997, 1998, and 1999.

   In October of 1998, due in large part to a drastic reduction in the size of 
   the nuclear submarine fleet, the U.S. Navy announced that they could no longer 
   facilitate the dedicated missions. In an effort to try and continue the SCICEX 
   program, the Navy and the science community agreed upon shorter duration 
   missions that included data collection for science but did not include 
   civilian scientists on board the submarines. These were coined Science 
   Accommodation Missions (SAMs). To date, four SAMs have been completed in 2000, 
   2001, 2003, and 2005. More routine opportunities to collect SCICEX data during 
   SAMs are expected.
