The East China Sea Seafloor Observatory and its upgraded project

Abstract

The East China Sea Seafloor Observatory, the Xiaoqushan seafloor observatory which located between 30° 31′44″N, 122° 15′12″E and 30°31′34″N,122°14′40″E, was built on April 21st, 2009. The submarine optical fiber composite power cable is landed on the platform by The East China Sea Branch, State Oceanic Administration of the People's Republic of China, and the power is continuously supplied by the solar panels and solar battery on the top of the platform. The real time data are directly sent through the cable to the platform and are transmitted by CDMA wireless to the receiver at the State Key Laboratory of Marine Geology of Tongji University. In order to become not only a testbed but also an integrated observation station, an upgraded project for the East China Sea Seafloor Observatory which was financial aided by Shanghai Science and Technology committee will start in October, 2011. A common use junction box to realize plug-and-play for general ocean sensors will be designed to instead of the former special junction box. Some instruments and sensors for physical oceanography, marine geological, seismological and tsunami observations will be installed in the observatory. The Cyberinfrastructure which include a long distance controlling visualization system for remote controlling seafloor measurement devices, a geographical information system for applications and an observation database will be designed during the research. A series criterion for the observatory operational procedure, the installation and the equipments test will be established at the same time.
