In the center of figure 8. 3 and still under development is what 

 we refer to as the basic system. This is the one -- at this mo- 

 ment -- that appears to have best possibilities for early and wide- 

 spread application in all three instrument suits. The objective 

 is to include in a single housing, as many sensors as feasible to 

 measure electronically various oceanographic variables. 



We have mentioned suits and systems of instruments and I 

 think it would be helpful to spend a little more time on each of these 

 terms. When we speak of "suits" of instruments, we are speaking 

 of the vertical columns in figure 8. 4. There is a suit contemplated 

 for each major category of platforms, survey ships, synoptic ships, 

 and ships of opportunity.
