This system was developed for sensing of seabed condition with real-time observation at depth of up to 5,000 meters by employing high tensile optical fiber mechanical towing cable (OFM cable).
The system consists of the submarine vehicle which contains various precision sensors (CTD, water sampler etc) and two still-video cameras, the contorol and monitoring unit on board and the OFM cable.
In 1990-1991, the system was seted on a new "Hakuhou Maru" and it was able to be used at maximum depth of 5,500 meters successfully. We expext that this monitoring system will be widely used for some academic resercheres and for exploration of deepsea natural resouces.
