海底观测系统是海洋科学从“考察”转向“观测”的重要设施.最近在杭州湾口外的东海内陆架(30°31′44″N,122°15′12″E～30°31′34″N,122°14′40″E)建成东海海底联网观测小衢山试验站.该试验站包括双层铠装海底光电复合缆,联接具有不同型号的水密接插头、实现能源自动供给和通信传输的基站特种接驳盒,并在基站防拖网与仪器安装架上安装3种海洋观测仪器;光电复合缆通过海洋平台登陆,由台上的太阳能蓄电池实施不间断的能源供应;现场海洋观测数据通过光电复合缆传输到平台后经CDMA无线网络实时发送到实验室服务器上.试验系统已于2009年4月开始正常运行,在本文中将例举部分数据在近底边界层动力过程和海平面高度异常研究方面的初步应用,分析了底应力在不同时间尺度上的变化规律以及2010年智利大地震引发的海啸对东海近岸的影响.试验站的建成是我国海底观测网建设迈出的第一步,不仅积累了经验,而且一年多来的连续观测资料表明海底观测具有重要的科学价值.
The undersea observation system is an important facility for marine sciences to shift from “inspection” to “observation.” Recently, the East China Sea continental shelf (30 ° 31’44 “N, 122 ° 15’12” E ~ 30 ° 31’34 “N, 122 ° 14’40” E) Completed the Qiaoshan Experimental Station of the East China Sea Submarine Networking Observatory, which consists of double-armored submarine optoelectronic composite cables with different types of watertight plugs for energy Automatic supply and communication transmission base station special connection box, and in the base station anti-trawl and equipment installation rack installation of three kinds of ocean observation instruments; photoelectric composite cable landed through the ocean platform by Taiwan’s solar energy batteries to implement uninterrupted energy supply; The on-site ocean observational data was transmitted to the platform via optical and electrical composite cable and then sent to the laboratory server via CDMA wireless network in real time.The test system started normal operation in April 2009, and some data will be exemplified in the near bottom boundary layer Process and sea level anomalies, the paper analyzes the law of bottom stress variation on different time scales and the impact of the tsunami triggered by the Chilean earthquake on the offshore of the East China Sea in 2010. The completion of the pilot station is The first step towards the country’s sea floor observatory network construction, not only accumulated experience, and more than a year of continuous observations show that the sea floor observation has important scientific value.
