Seafloor observation system using the underwater cable is one of the most reliable ways to provide high-speed data transmission and continuous power feeding to underwater devices. Recent evolution in the optical submarine cable and Internet technology make it possible to develop a versatile scientific submarine cable network. IEEE OES (Institute of(More)
Large scale, long term submarine cabled observatory systems represent a new direction for oceanographic research infrastructure. The power and bandwidth of recent generation technology provides several orders of magnitude more capability than has ever been available to the oceanographic research community. Coupled with a multi-decade observing presence,(More)
Seafloor observation system using the underwater telecommunication cable is one of the most reliable ways to secure high-speed data transmission and continuous power feeding to underwater devices. In this paper a new scientific submarine cable system will be presented that were proposed by the technical committee organized by IEEE OES (Institute of(More)
Recently, some regional ocean observation networks using submarine cables are proposed or being planned all over the world to gather three-dimensional continuous, and long-term multidisciplinary data in vast area. Autonomous Underwater Vehicles (AUVs) will also play an important role in this observation system. In this paper, the authors will show the(More)
