Marine Science Affairs 



reflecting primarily increased support of fleet operations and priority devel- 

 opments in military ocean engineering, as follows : 



Millions of dollars 

 — surveying the properties of the ocean and ocean bottom 



(Navy) $28.3 



— marine science and technology in support of weapon systems 



(Navy) 35.3 



— development of undersea search, rescue, recovery, and man- 

 in-the-sea capability — Deep Submergence Systems Project 



and closely related efforts (Navy) 77.4 



— test and calibration facility for instrumentation (Navy) 1. 8 



— marine science in support of safeguards for limited test ban 

 treaties — VELA program (Advanced Research Projects 

 Agency) . 2 



These data of course do not include much of the Navy's applied research 

 and development effort, totalling $2.1 billion in FY 1969, the bulk of which 

 is directed toward development of components for specific weapons systems 

 and construction of prototype equipment. 



Ocean Surveys for Defense Systems 



The purpose of these surveys is to obtain comprehensive oceanographic, 

 hydrographic, and acoustical information about ocean areas of the world 

 in which our naval forces operate. The surveys provide environmental data 

 both to support current fleet operations and to design future systems. Ocean- 

 wide surveys, including mapping and charting programs described in Chap- 

 ter XII, acquired vast quantities of precise environmental data over 

 millions of square miles of the North Atlantic and North Pacific Oceans and 

 the Mediterranean Sea in FY 1968. Over one-half million track-miles of 

 controlled sounding lines, 300,000 track-miles of gravity data, 150,000 

 track-miles of seismic sub-bottom profiles, and 260,000 miles of geomagnetic 

 data were completed. An additional 210,000 miles of airborne geomagnetic 

 measurements were obtained by the Navy's Project Magnet aircraft. 



Fifteen Navy surface ships and four airplanes are assigned full time to 

 the collection of oceanographic, hydrographic, and other related geophysical 

 and meteorological data. This large oceanographic fleet is being modernized 

 by the replacement of converted, obsolescent ships with new ones specifically 

 designed and instrumented for oceanographic work. In addition to the full- 

 time fleet, other ships are under contract to the Navy for special oceano- 

 graphic projects. Still other ships of the Navy and the Coast Guard are 

 used on an opportunity basis to obtain oceanographic information.
