this depth and geographic location. (Animal growth in 

 tropical areas should be considerably less. ) 



7. Noise production by bivalves and associated 

 fishes would raise the ambient noise level in the area of 

 the moored hull. 



RECOMMENDATIONS 



1. Further studies of fouling processes in the deep 

 ocean environment should be initiated. 



2. Better communication should be arranged between 

 operational organizations of the U. S. Navy and scientific 

 personnel working in the oceanographic field so that prompt 

 inspection can be made of all such structures recovered 

 from deep sea moorings.
