| The state of art on the typical seafloor observatories is researched in this paper. The scale, constructions, instruments type and the current state of China seafloor observatories are presented. And the tendency of the seafloor observatory is summarized in the end. The devices layer in the observatory network of Japan, Canada, American and Euroupe are investigated, and the researching actuality of observatories in the Taiwan region, the east China sea, and the south China sea are analysed. Moreover, the significance of advanced observation network to the construction of China's submarine observation network is discussed. The conclusion of the seafloor observatories’ tendency can be summaried to this: Single node observatory speeds validation of underwater instruments and sensors, regional cable observatory accelerates the development of multi-disciplines and technology, and buoyed observatory reduces the costs in far offshore network construction phase. |
