II. a. SHIPBOARD OCEANOGRAPHIC SURVEY SYSTEM 



Primary Use: 



To be utilized on oceanographic survey ships incorporating the 

 most up-to-date techniques for collection, storage, reduction, and 

 possible transmission of oceanographic data. 



Requirements and Specifications: 



a. For utilization on oceanographic survey ships with the ship 

 in any of the following modes of operation: (1) stopped ("lying-to"), 

 (2) at anchor, and (3) underway at slow speeds (0-3 knots). 



b. To perform efficiently, effectively, and safely in sea 

 states of through 5. 



c. To be operable in water depths of 0-6, 500 fathoms. 



d. To be able to simultaneously accommodate any or all of the 

 sensor modules listed in subparagraph e. following.
