东海海底观测小衢山试验站
摘要
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.
