THE PROBLEM 



Investigate oceanographic factors, particularly 

 internal waves, that influence naval operations and equip- 

 ment. This report presents a bibliography of over 300 

 listings and summarizes important published results of 

 investigation. 



RESULTS 



1. Internal waves exist in the ocean as a rule rather 

 than an exception. Energy is transported by them in 

 channels that are similar to sound channels. Their effect 

 on naval exercises and equipment, particularly functions 

 involving the use of underwater sound, can be expected to 

 be more pronounced in these channels. 



2. Although theory and observation are still not 

 adequate for a full understanding of the phenomenon, 

 western literature prior to June 1963 contains more than 

 300 publications dealing with internal waves in the atmo- 

 sphere, lakes, and seas. 



3. These publications are listed in the comprehensive 

 bibliography which is part of this report. 



RECOMMENDATIONS 



1 . Locate, compile, and keep up to date available 

 information concerning internal waves in the sea; use both 

 western and eastern sources. 



2. Exploit this information in naval research.
