Juan de Fuca Strait Acoustic Doppler Current Profiler 2 MHz Deployed 2020-09-05

The Nortek Aquadopp Profiler AQP5431 AQD8398 was deployed on 2020-09-05 at Juan de Fuca Strait. Juan de Fuca Strait is a large body of water that connects the Salish Sea to the Pacific Ocean. This device is a Acoustic Doppler Current Profiler 2 MHz. Acoustic Doppler Current Profilers 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.

Nortek Aquadopp剖面仪AQP5431与AQD8398于2020年9月5日部署于胡安德富卡海峡（Juan de Fuca Strait）。该海峡是连通萨利什海与太平洋的大型水域。本设备为2兆赫兹声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，以下简称ADCP），此类仪器属于水声设备，工作原理与声呐相似。ADCP可同时测量多个预设深度处的海流流速与流向，其利用声波的多普勒效应，通过海水中颗粒物对声波的散射获取指定深度范围内的海流数据。本次部署将仪器搭载于固定式平台。此次部署产生的数据集已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外开放；所有数据均遵循既定规范开展质量管控，并生成衍生数据产品。
