Folger Pinnacle Acoustic Doppler Current Profiler 2 MHz Deployed 2014-07-23

The Nortek Aquadopp Profiler AQD 2958 was deployed on 2014-07-23 at Folger Pinnacle. Folger Pinnacle is an isolated pillar-like feature in Folger Passage, where biodiversity and coastal ecosystems are observed. 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剖面测量仪AQD 2958（Nortek Aquadopp Profiler AQD 2958）于2014年7月23日在福尔杰尖峰（Folger Pinnacle）完成部署。福尔杰尖峰是福尔杰航道（Folger Passage）内一处孤立的柱状地貌，该区域拥有丰富的生物多样性与海岸生态系统。该设备为2兆赫声学多普勒海流剖面仪（Acoustic Doppler Current Profiler，ADCP），此类仪器属于水声探测设备，工作原理与声呐相似。声学多普勒海流剖面仪可同时测量多个预设深度的海流流速与流向，通过利用声波被海水中悬浮颗粒物散射产生的多普勒效应，在指定深度范围内完成观测。本次部署将该仪器搭载于固定平台，采集所得数据已完成存档，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；所有数据均遵循行业既定标准完成质量管控，并生成了标准化衍生数据产品。
