Strait of Georgia Central Acoustic Doppler Current Profiler 150 kHz Deployed 2009-09-28

The RDI Workhorse Quartermaster ADCP 150 kHz (SN 8580) was deployed on 2009-09-28 at Strait of Georgia Central. Strait of Georgia Central is a central area in 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 2.0 digital infrastructure, with quality assurance and derived data products following established practices.

RDI Workhorse Quartermaster型150kHz声学多普勒流速剖面仪（序列号8580）于2009年9月28日部署于乔治亚海峡中部区域。乔治亚海峡中部是乔治亚海峡的核心水域。该设备为150kHz声学多普勒流速剖面仪。声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，简称ADCP）是一类水声学仪器，其工作原理与声呐相仿。ADCP可同时在多个预设深度处同步测量海流的流速与流向。该设备利用声波在海水悬浮颗粒物上散射产生的多普勒效应，实现指定深度范围内的海流参数探测。本次部署的仪器搭载于固定观测平台。本次部署获取的数据集已完成归档，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共享；所有数据均遵循既定行业规范完成质量管控，并生成了配套的衍生数据产品。
