 able of interfering with underwater acoustic listening or ranging. 

 Future cooperative work with nonmilitary agencies such as the 

 Bureau of Commercial Fisheries will contribute to studies aimed 

 at devising methods of increasing fish catches and automation 

 of the processing, storage, and retrieval of the diverse data required. 



SEA ICE 



Since polar operations are now of strategic interest to the 

 national defense, information on the occurrence and nature of sea 

 ice and icebergs is mandatory. Although synoptic ice forecasting 

 is required for high latitude resupply, surface, and subsurface 

 operations, the analysis and presentation of historical data provide 

 the mariner with planning information on seasonal accessibility 

 of ports influenced by ice, as well as the general navigability of 

 polar and subpolar waters.
