Fraser River Delta Lower Slope Acoustic Doppler Current Profiler 300 kHz Deployed 2015-08-30

The RDI Workhorse Monitor ADCP 300 kHz (SN 17955) was deployed on 2015-08-30 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300千赫兹声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，简称ADCP，序列号：17955）于2015年8月30日布放于弗雷泽河三角洲下斜坡海域。该站点位于弗雷泽河三角洲下斜坡区域，水深约150米。该设备为300千赫兹声学多普勒流速剖面仪，声学多普勒流速剖面仪（ADCP）是一类与声呐原理相似的水声学仪器，可同时在多个预设深度处同步测量水流的流速与流向。ADCP利用声波的多普勒效应工作，该声波在指定水深范围内会被海水中的颗粒物散射。本次布放的仪器搭载于固定平台。本次布放获取的数据已通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施完成存档并对外开放，所有数据均遵循既定行业规范开展质量管控，并生成了相应的衍生数据产品。
