Potential Users and Estimated Number of Units Which They May 

 Require : 



a. U. S. Navy (hydrographic-oceanographic survey ships, basic 

 research ships, and applied research ships) - 19 to 25. 



b. U. S. Coast and Geodetic Survey - 2 to 6. 



c. Certain activities \^ithin scientific coinmunity - 10 to 15. 



d. Bureau of Commercial Fisheries - 2.

Recommendation Where System Should Be Researched and Developed^ 



U. S. Industry. 

 Relative Importance to U. S. National Oceanographic Program : 



Individual instruinent priority 1. 



I.b. CURRENT METER FOR CONDUCTING COASTAL AND 

 OCEANIC SUBSURFACE CURRENT SURVEYS 



Primary Use : 



This is a precision instrument to be utilized on oceanographic 

 survey vessels for conducting subsurface current studies and sur- 

 veys in coastal and oceanic areas with the ship anchored or "lying- 

 to. " It miust measure and record precisely the direction and speed 

 of the subsurface currents. 



Requirements and Specifications : 



a. To perform reliably and accurately on survey ships which 

 are anchored or "lying-to- 



b. To be operable in depths varying from to 6, 500 fathoms 

 with no adverse effects thereto due to hydrostatic pressure. 



c. To be so designed as to be utilized individually or in mul-
