40 THE NAVY OCEANOGRAPHIC OPERATIONS PROGRAM 



Because of the high cost of these new nteters and deep-water 

 surveying in general, most Navy gravity projects are conducted 

 to meet military requirements, but upon occasion purely scientific 

 efforts are supported. One such effort was the recent gravity 

 survey in the vicinity of New Guinea by the University of Hawaii's 

 Institute of Geophysics. Shipboard measurements by the USS 

 WANDANK and the HMS DAMPIER obtained off-shore data 

 for a Study of the area's geology. Also, because of the Navy's 

 world-wide survey efforts — including land measurements by 

 PROJECT MAGNET— considerable support has been given to 

 establishing both the European and North American Calibration 

 Lines and to other international cooperative efforts to establish 

 a world-wide network of gravity base stations. 



The Navy is participating in the Department of Defense project 

 for development of a helicopter gravity collection system. Test 

 equipment has been selected and the test, plans for which are well 

 underway, will be carried out jointly by the Army, Navy, and 

 Air Force.
