Fraser River Delta Lower Slope Acoustic Doppler Current Profiler 600 kHz Deployed 2016-10-08

The RDI Workhorse Monitor ADCP 600 kHz (SN 7992) was deployed on 2016-10-08 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 600 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600kHz声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，ADCP，序列号SN 7992）于2016年10月8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，作业水深约150米。本设备为600kHz声学多普勒流速剖面仪。声学多普勒流速剖面仪（ADCP）是一类类似声呐的水声学探测仪器，可同时测量多个预设深度层的水流速度与流向。ADCP利用声波在海水颗粒物上散射产生的多普勒效应，在指定深度范围内完成流速与流向的监测。本次布放采用固定式平台搭载方式。本次布放获取的原始数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外共享，所有数据均按照既定规范完成质量管控，并配套生成符合行业标准的衍生数据产品。
