of the various experiments. For example, topographic surveying experiments 

 could best be performed on a rock bottom where the water is very clear, 

 whereas foundation experiments need a soft cohesive bottom material to be 

 meaningful. It might be possible, however, to find a site where both 

 experiments could be performed. 



Description of Possible Experiments 



In SEACON the emphasis is on the construction experiments themselves 

 and what these experiments will do to advance deep ocean technology. The 

 end item (i.e., what is constructed) is of much less importance. Equipment 

 or hardware to be used at sea in SEACON may include the following: 



Surface support ships 

 Warping tug 

 Submersible workboat 



Tethered work systems (e.g. , Cable -Controlled Underwater Re- 

 Manipulators c°very Vehicle) 

 Manipulator tools 

 Load-handling lines 



Long Range Accuracy (LORAC) location system 

 Depth-measuring devices 

 Coring devices 



Deep Ocean Test Instrumentation Placement and Observation System 

 In-situ plate bearing device 

 In-situ vane shear device 

 Automatic topographic plotting system 

 Oceanographic instruments 

 System for placing plastic overlays 

 Sub-bottom profiling equipment 

 Navy Experimental Manned Observatory 



Items to be emplaced or constructed at the SEACON site may include the 

 fo3J. owing: 



Current meters 



Electrical power connectors 



Power generator 



Power transmission system 



Footings and foundations 



Anchoring and mooring systems 



Overlays (plastic) 



Concrete cylinders (dry one-atmosphere interior) 



Seals and gaskets 



Windows 



Benchmarks 



Release devices
