Upper Slope South Acoustic Doppler Current Profiler 600 kHz Deployed 2019-08-26

The RDI Workhorse Monitor ADCP 600 kHz (9339) was deployed on 2019-08-26 at Upper Slope South. Upper Slope South is a location within Barkley Canyon, which is located on the upper continental slope. 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.

RDI Workhorse Monitor型600千赫兹声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，ADCP，型号9339）于2019年8月26日部署于南上斜坡（Upper Slope South）。南上斜坡是地处大陆架上斜坡区域的巴克利峡谷（Barkley Canyon）内的一处区域。该设备为600千赫兹声学多普勒流速剖面仪。声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，ADCP）属于水声仪器，工作原理与声呐类似。ADCP可同时在多个预设深度处测量水流速度与流向，其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。本次部署的设备搭载于固定平台之上，此次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 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，并配套生成了衍生数据产品。
