UNDERWATER TELEVISION SYSTEM FOR SEA FLOOR INVESTIGATIONS 
Sketches 
(To be provided) 
Primary Uses 
To be utilized on oceanographic survey ships in coastal and 
oceanic areas to obtain continuous observations of and to investigate 
the sea floor topography. 
Requirements and Specifications: 
a- To be operable in water depths of O to 6,500 fathoms, with 
the ship stopped ("lying-to") or underway at slow speeds (0 to 5 knots). 
b. The system must include a device for indicating the precise 
height of the camera above the sea floor. 
c.- The design of this system must include a provision for "taping" 
all of its coverage for re-run at a later time. 
d. The camera carrying unit must contain, or have attached to it, 
an illuminating device which is capable of adequately lighting the 
T.V. picture field at all depths and which has a duration of at least 
two hours of sustained operations. 
e. There must be provision for remote focus and lens control from 
shipboard. 
f. The camera carrying unit must be streamlined, rugged, compact, 
- and capable of being handled readily and easily on board ship during 
operations. 
Potential Users and Estimated Number of Units Which They May Requires: 
a» U. S. Navy (basic research, applied research, and oceanographic 
survey ships) - 15 to 30 
b. U. S. Coast and Geodetic Survey - 5 to 15 
c. Certain activities within Scientific Community - 5 to 15 
d. Bureau of Commercial Fisheries - 2 to 8
