A new propulsion system has been successfully tested for this pontoon used in 

 the Large Object Salvage System Project. 



commercially, but models and instrument characteristics change 

 rapidly. The result of frequent changes is to diminish reliability, 

 foster excessive spare parts inventories, and require continuous 

 retraining of operators and maintenance personnel. Present efforts 

 are directed to the design of a reliable and easily maintained deep 

 ocean current meter. Progress of the work thus far has been good and 

 includes the preparation of specifications and drawings for the 

 meter. Recent at-sea tests of several of these current meters were 

 quite satisfactory. Future efforts in instrument improvement will 

 include work on subbottom profilers. 



In recent years the tools and techniques developed by the Navy's 

 ocean engineering program have assisted the civilian community.
