基于10米浮标载体的锚链式剖面观测系统实践之一——自容式采集方式

Anchor chain-type profiling observation system based on 10m buoy—self contained acquisition mode

为了对我国近海海域进行剖面观测,获取到多层位水体的多要素观测数据,尝试依托中国近海海洋观测研究网络东海站10 m浮标系统的锚系,采用在锚系上挂载自容式组合传感器方式,获取到8个观测周期共412 d的有效剖面观测数据,观测层位分布于10,20,30 m 3个水层;通过结合浮标获取的表层温度数据与3个水层的对比分析表明,锚链式剖面观测方案在实用性和可推广性方面具有显著优势,是基于海面浮标载体进行剖面观测的有益尝试,可在我国构建的海洋浮标观测网络上进行广泛应用,将为我国近海海洋科学研究提供弥足珍贵的水面-水体全序列系统观测数据资料,从而为近海海洋科学研究取得突破性进展提供重要的数据支撑。

A new system is developed to conduct cross-sectional observations of coastal waters and obtain multi-layered and multi-factor water observational data. Self-contained combined sensors are mounted on mooring chains on a 10 m-buoy system located in the East Sea station of an offshore marine observation and research net-work （OMORN）, and 412 days of effective cross-sectional observational data in three water layers at 10 m, 20 m, and 30 m are obtained. This chain-type cross-sectional observational mode is advantageous in a wide sprectra of applications as combined surface data from the buoy is acquired. If applied to all buoys in the Chinese coastal buoy observation network, it would provide a valuable data source of the complete sequence water and would thus pro-mote a breakthrough in marine scientific research.
