THE NAVY OCEANOGRAPHIC OPERATIONS PROGRAM 



Preparing to obtain a large water sample for radioisotope determinations. 



Upon the completion of such studies and depending on the con- 

 clusions reached, the systems are placed in a fully operational 

 status or are modified for better compatibility with oceanographic 

 survey applications. 



SOUND PROPAGATION 



New Navy weapons systems and operating needs have created 

 unprecedented demands for rapid, oceanwide environmental 

 measurements. To meet these needs, the U. S. Navy has com- 

 menced extensive surveys to obtain acoustical, oceanographic, 

 and geophysical data in areas of strategic importance. A 

 secondary objective, important to the Navy's immediate opera- 

 tional capability and to long-range research, is the efficient and 

 systematic collection, compilation, and presentation of oceano- 

 graphic and geophysical data.
