Fraser River Delta Lower Slope Acoustic Doppler Current Profiler 300 kHz Deployed 2014-03-08

The RDI Workhorse Monitor ADCP 300 kHz (SN 17955) was deployed on 2014-03-08 at Fraser River Delta Lower Slope. This site is located on the lower slope of the Fraser River delta, where depth is approximately 150 metres. 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.

RDI Workhorse Monitor型300 kHz声学多普勒流速剖面仪（序列号SN 17955）于2014年3月8日部署于弗雷泽河三角洲下斜坡站点。该站点地处弗雷泽河三角洲下斜坡区域，水深约150米。该设备为300 kHz声学多普勒流速剖面仪（Acoustic Doppler Current Profilers，缩写ADCP），此类水声探测仪器与声呐原理相似，可同时对多个预设深度的水流速度与流向进行同步测量。ADCP依托声波在海水颗粒物散射时产生的多普勒效应，在指定深度范围内完成流速流向探测。本次部署将设备安装于固定平台之上，此次采集的所有数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外提供服务。相关数据均遵循既定规范完成质量管控，并生成了配套衍生数据产品。
