FIGURE O . O 

 RESEARCH SHIP 



Figure 8. 3 gives some appreciation for the instrumentation 

 now carried by a research or survey ship. Merchant or commer- 

 cial ships on tight schedules cannot be expected to instrument m 

 this manner nor can fleet units acconnmodate installations such as 

 these. 



For example, there is a hull-mounted surface wave sensor 

 and a surface temperature probe. Separate measurements to vary- 

 ing depths are taken on such items as radioactivity, light trans- 

 mission, and Carbon i4. 



Separate installations for current meters, a geothermai 

 probe, a dredge, and a bottom sampler are deep, brute force 

 equipments. Many separate hoists and many separate instrunnent 

 trips are necessary to measure the variables involved.
