Folger Pinnacle Acoustic Doppler Current Profiler 2 MHz Deployed 2010-08-23

The Nortek Aquadopp Profiler AQD 2958 was deployed on 2010-08-23 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.

诺泰克（Nortek）Aquadopp剖面仪AQD 2958于2010年8月23日部署于福尔杰尖柱（Folger Pinnacle）。福尔杰尖柱是福尔杰水道（Folger Passage）内一处孤立的柱状地貌，该区域已观测到丰富的生物多样性与海岸生态系统。该设备为2 MHz声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，ADCP）。声学多普勒流速剖面仪属于水声探测仪器，其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，通过检测深度范围内被海水颗粒物散射的声波的多普勒效应完成测量。本次部署将该仪器搭载于固定式平台之上。本次采集的数据已完成归档，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，并衍生出配套数据产品。
