Saanich Inlet Sill Acoustic Doppler Current Profiler 300 kHz Deployed 2019-11-01

The RDI Workhorse Monitor ADCP 300 kHz (SN 1600) was deployed on 2019-11-01 at Saanich Inlet Sill. Saanich Inlet Sill is a shallow bottom feature in the Saanich Inlet. The sill influences flow of oxygenated water and seasonal cycles. This device is a Acoustic Doppler Current Profiler 300 kHz. Acoustic Doppler Current Profilers (ADCP) are hydroacoustic instruments, similar to sonars. ADCPs measure current speed and direction at multiple predetermined depths simultaneously. ADCPs use the Doppler effect of sound waves that are scattered by particles in seawater over a depth range. It was deployed on a fixed platform. Data from this deployment were archived and made available through Ocean Networks Canada's Oceans 2.0 digital infrastructure, with quality assurance and derived data products following established practices.型号为RDI Workhorse Monitor的300 kHz声学多普勒海流剖面仪（Acoustic Doppler Current Profiler，ADCP，序列号SN 1600）于2019年11月1日部署在萨尼奇湾海槛（Saanich Inlet Sill）处。萨尼奇湾海槛是萨尼奇湾内一处浅海床地貌，会对含氧水的流动及季节循环过程产生影响。该设备为300 kHz声学多普勒海流剖面仪（ADCP），此类仪器属于水声仪器，工作原理与声呐相似。ADCP可同时测量多个预设深度处的海流流速与流向，其借助声波的多普勒效应，通过声波在海水颗粒物上的散射获取指定深度范围内的海流数据。该设备被部署于固定式观测平台上。本次部署获取的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外开放；所有数据均遵循既定规范完成质量管控，并衍生出配套数据产品。
