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 3.0 digital infrastructure, with quality assurance and derived data products following established practices.

型号为RDI Workhorse Monitor的300千赫兹声学多普勒流速剖面仪（ADCP，序列号1600）于2019年11月1日部署于萨尼奇湾海槛（Saanich Inlet Sill）。萨尼奇湾海槛（Saanich Inlet Sill）是萨尼奇湾内一处浅海底部地形，其会对含氧水的流动及季节循环过程产生影响。该设备为声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，ADCP），这类仪器属于水声探测设备，与声呐原理相似。ADCP可同时测量多个预设深度处的海流流速与流向，其通过海水中颗粒物在深度范围内散射的声波，利用多普勒效应完成流速流向探测。该设备部署于固定式观测平台之上。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 3.0数字基础设施对外提供，其质量保证与衍生数据产品均遵循既定行业规范。
