Cabled observatories are seabed oceanographic research platforms connected to the surface by undersea cables. Such cables supply both power and telecommunications to instruments.〔(Vendor description (L3) )〕 By removing the limitations of undersea power sources and sonar or RF communications, cabled observatories allow persistent study of underwater phenomena.〔(WHOI page )〕 A single cable can support multiple observation sites via individual "drops;"〔(Vendor description (Oceanworks) )〕 multiple or branching cables may then provide data in 2D or 3D. The extent of coverage is limited by the high cost of laying dedicated undersea cable. Initial experiments used abandoned communications cables; efforts are in progress to extend observations at lower cost by accessing more such cables. ==List of cabled observatories== *Monterey Accelerated Research System (MARS) *NEPTUNE *VENUS *Liquid Jungle Lab (LJL) Panama- PLUTO *H2O (Hawaii-2 Observatory)- early experiment () *ALOHA () *ESONET 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「cabled observatory」の詳細全文を読む スポンサード リンク
