Manipulator. A manipulator, or mechanical arm, capable of 

 collecting specimens was provided as part of the submersible. The 

 arm was incapable of use for or adaptation to extensive core sampling 

 but met the minimal scientific needs. 



Instrumentation Power and Signal Requirements 



The instrumentation power and signal requirements were made 

 independent of the control and power supply systems of DEEPSTAR. 

 Silvercell batteries supplied the DC power (24-28 volts). AC power 

 was provided by static inverters. The power package was located 

 within the personnel sphere beneath the observer's couch. Three 

 power packages were assembled, providing two spares to be carried 

 aboard the support ship, one of which was on recharge during each 

 dive. A separate terminal board within the sphere consisting of 50 

 connections was allocated, thus allowing instrumentation changes to 

 be accomplished without interruption to or interference with the sub- 

 mersible's system. Through-hull penetrations allocated to "science" 

 from the terminal board were externally terminated in eight female 

 connector junction boxes, located forward of the sphere and adjacent 

 to the brow. Four junction boxes providing 32 connections were 

 available for brow instrumentation hookups. A single eight-connector 

 junction box was located aft of the personnel sphere. All junction 

 boxes were Electro Oceanic-type, therefore all instrumentation was 

 equipped with suitable male connectors. This standardization was 

 made on all scientific equipments. 



Standard Sphere Instrumentation 



Standard instrumentation is that which is added on request of 

 the user laboratory or which may be already a part of the submersible, 

 as covered in negotiations and specified as a contract requirement. 

 These items may vary, dependent upon mission profiles established 

 as part of the scientific program. Fig. 3 illustrates the sphere 

 layout. The starboard side is devoted to the scientific program. 



Viewports. An observation capability to enable the scientist 

 to view the water column, sea floor, or the performance of the ex- 

 ternal instrumentation, was a "must". To insure continuous view- 

 ing a separate viewport from that of the pilot was specified. This 

 "instrument" obviously must be a part of the submersible. 



Cameras. Mission profiles established the necessity of photo- 

 graphic capability, in color, for both still and motion pictures. The 

 300-frame, lO-jL still camera was mounted externally of the sphere
