MASTER OCEANOGRAPHIC SHIPBOARD DATA LOGGING AND PROCESSING SYSTEM 
Sketchs 
(To be provided) 
Primary Use: 
To be utilized on oceanographic survey ships. In view of the 
many ships scheduled to be employed in ocean-wide research and survey 
programs, it is imperative that the maximum quantity of data possible 
be processed on board ship. This data processing system, through 
being sufficiently versatile to handle a variety of data inputs, should 
provide the required on-board data analyzing, logging, processing, and 
storaye capability. This system will expedite the availability of 
"smoothed" field data for utilization by either the scientific leader 
or survey party chief "in the field" in order to achieve optimum re- 
sults. 
Requirements and Specifications: 
a. To be utilized and perform reliably under the following modes 
of survey type of operations: (1) ship stopped ("lying-to"), (2) ship 
anchored, and (3) ship underway at speeds 0-18 knots. 
b. System to function reliably in sea states O through 5. 
c. The system should employ solid state circuitry wherever possible 
to reduce size, weight, and heat generation. 
d. It should be versatile enough to record information from a 
large variety of sensors and transducers, in both digital and analog 
‘form, and to include such key information as time, position, course, 
speed, ship, cruise number on all data records. 
e. It should employ modular construction, plug-board system pro- 
gramming, and stored program system control. 
f. It should incorporate, but not be limited to, the following 
major components to achieve the above: 
(1) A multi-channel high quality analog magnetic tape recorder 
having modular read-write electronics for direct and FM recording.
