Scattering and attenuation of underwater sound by marine life will be 

 studied by two methods. An attempt will be made to correlate 

 scattering and attenuation measurements with an analysis of the plankton 

 collected in the area, A second study will be based on collection of 

 plankton and nekton from within the deep scattering layer as located 

 by echo sounders and from concurrent photographs and television 

 observations . 



This research program in biology at the Hydrographic Office is funded 

 entirely with non-research funds „ 



Bureau of Ships FY-62 $166,000 



FY-63 $198,000 

 The Bureau will expand the Navy Electronics Laboratory' s program of 

 identification and classification of noises originating from marine 

 organisms. The expanded program will include analysis of ambient 

 noise recordings from San Clemente Island and Cape Prince of Wales 

 to determine seasonal and other characteristic s, In addition, the 

 research program of the bathyscaph TRIESTE, also carried out by scien- 

 tists at NEL, will include studies of the population of the sea and the 

 correlation of the population with the physical and chemical properties 

 of the sea at various depths.

 Information on marine borers which infest waters of the United States 

 will be analyzed in order to determine the expected useful life of 

 wood and concrete structures in coastal waters . This analysis will 

 also serve to indicate the economic justification of various methods 

 of protecting against these borers. Biological studies of borers 

 are not planned; rather the project is an analysis of the findings 

 of others for application to the needs of the Corps, 



Beach Erosion Board FY-62 $ 3,000 



FY-63 $10,000 

 The interests of the Board in this research objective are similar to 

 that of the Office of the Chief of Engineers, as described in the 

 preceding paragraph. These studies, which concern marine borer 

 activity, will be pursued jointly by the Office of the Chief of 

 Engineers and the Board,

The Weather Bureau and the Coast & Geodetic Survey do not budget funds 

 specifically for research on the living populations of the sea. 

 However, the Coast Survey contributes indirectly in two ways. First, 

 it encourages other agencies and private institutions to place biolog- 

 ical oceanographers aboard its ships, and it does on request collect
