or stop to collect oceanographic data, (b) Synoptic Ship . The 

 present early developmental phases of instrumenting these ships 

 have been limited to preparing them for making observations when 

 stopped. As the program develops, similar instruments for the 

 synoptic ship will include concepts for handling instruments when 

 underway. This system will be described in some detail during 

 tomorrow's session, (c) Survey Ship . Underway and stopped 

 operations are necessary in order to cope with the large variety 

 of oceanographic observations made by this type of vessel. 



Another factor bearing on the design of required instruments 

 is the amount of portability required: (a) Portability is a very crit- 

 ical aspect for instruments used on ships of opportunity. Here we 

 are talking about many varied types of platforms which require 

 shifting of instrumentation installations from one vessel to another, 

 (b) For the synoptic ship, portability is less of a problem, in view 

 of a heavier and larger shipboard installation, (c) For survey 

 vessels it is visualized that practically all instrumentation will be 

 more or less of a permanent nature.
