Strait of Georgia East Acoustic Doppler Current Profiler 150 kHz Deployed 2017-11-02

The RDI Workhorse Quartermaster ADCP 150 kHz (SN 8497) was deployed on 2017-11-02 at Strait of Georgia East. Strait of Georgia East refers to an eastern area of the Strait of Georgia. This device is a Acoustic Doppler Current Profiler 150 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 3.0 digital infrastructure, with quality assurance and derived data products following established practices.

RDI Workhorse Quartermaster型150 kHz声学多普勒海流剖面仪（Acoustic Doppler Current Profiler，ADCP，序列号SN 8497）于2017年11月2日部署于乔治亚海峡东部海域。此处的乔治亚海峡东部指乔治亚海峡的东部片区。该设备为150 kHz声学多普勒海流剖面仪，此类设备属于水声学仪器，工作原理与声呐相仿。声学多普勒海流剖面仪可同时对多个预设深度的海流流速与流向进行测量，其利用声波在海水中悬浮颗粒上散射产生的多普勒效应，在指定深度范围内开展观测。本次部署的设备搭载于固定平台之上。本批次部署所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 3.0数字基础设施对外共享，所有数据均遵循既定规范完成质量管控，并产出了符合标准的衍生数据产品。
