Fraser River Delta Lower Slope Acoustic Doppler Current Profiler 300 kHz Deployed 2016-10-08

The RDI Workhorse Monitor ADCP 300 kHz (SN 17955) 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 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，ADCP，序列号SN 17955）于2016年10月8日部署在弗雷泽河三角洲下斜坡区域。该点位地处弗雷泽河三角洲下斜坡，水深约150米。该设备为300千赫兹声学多普勒流速剖面仪（ADCP）。声学多普勒流速剖面仪（ADCP）是一类与声呐相似的水声学仪器，可同时对多个预设深度的海流流速与流向进行同步测量。ADCP利用指定深度范围内海水中悬浮颗粒物散射声波后产生的多普勒效应完成观测。本次部署依托固定式平台开展。本次采集的数据已完成归档，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；数据质量保障及衍生数据产品制作均遵循既定行业规范。
