"Systems" refers to groups of instruments where possible com- 

 binations of sensors in common housings appear feasible. The "data 

 measurement" column represents the oceanographic variables in 

 which we are interested and their relationship to the various instru- 

 ment suits is indicated. 



The basic system offers the biggest early potential market as 

 the appearance of most of the variables across the board indicates. 



From an engineering standpoint, the expanded system appears 

 to be a logical and feasible extension of the basic suit. Automatic 

 data processing is extremely significant for these variables. Here, 

 there is immediate need for the application of data processing to 

 the survey product. 



The last system, individual instruments, takes us back to some 

 of the measurenrients that I noted previously where ponderous or 

 extremely complex equipment is involved. At this time, there 

 appears little possibility of incorporating these in compact sensor 

 housings. 



Although we have analyzed and broken down this problem by 

 general groupings of platforms and suits and systems of instruments, 

 I'm sure that everyone understands that this is just a nnethod of 

 organizing our approach. These various lines and boxes are by no 

 means fixed but simply represent planning assignments. Because 

 of the present unsatisfactory state of instrumentation generally, 

 breakthroughs should occur and we nnay well wind up with many 

 changes in this graph. Such improvements would point toward a 

 greater capacity to carry out survey work. It is not practicable to 

 discuss each of the oceanographic variables involved. They are 

 fully covered in the handout. 



Closely related to each platform are the major required opera- 

 tional characteristics of these three suits of survey instrumenta- 

 tion. (The engineering aspects of these three suits will be des- 

 cribed later by Mr. Gilbert Jaffe, Director of the Instrumentation 

 Division at the Hydrographic Office.) 



Certain aspects based on the mode of operation for each of the 

 three types of ships are better understood by a better under steind- 

 ing of the operation itself (fig. 8. 5): (a) Ship of Opportunity . This 

 type ship must remain underway in order to maintain tight operat- 

 ing schedules. It is a straight dollar loss if he is required to slow
