ASWEPS deep moored telemetering 

 oceanographic/meteorological buoy 



tracks. In addition to reducing ship damage, ice prediction has reduced the 

 time required for completion of naval operations in these remote areas. 

 New ice forecasting methods and increased knowledge of ice formation, 

 behavior, and deterioration will, as a result of more data from sateUites 

 and other more conventional sources, further benefit polar and under-ice 

 operations. 



The early success of the synoptic approach to ice observation and fore- 

 casting led to exploration of other facets of oceanographic forecasting.
