Folger Pinnacle Acoustic Doppler Current Profiler 2 MHz Deployed 2024-04-23

The Nortek Aquadopp Profiler AQD 2958 was deployed on 2024-04-23 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Aquadopp剖面仪AQD 2958（Nortek Aquadopp Profiler AQD 2958）于2024年4月23日在福尔杰海峰（Folger Pinnacle）完成布放。福尔杰海峰是福尔杰海峡（Folger Passage）内一处孤立的柱状地貌，该区域已被观测到拥有丰富的生物多样性与沿海生态系统。该设备为2兆赫声学多普勒海流剖面仪（Acoustic Doppler Current Profiler，以下简称ADCP）。声学多普勒海流剖面仪属于水声仪器，其工作原理与声呐相似，可同时测量多个预设深度处的海流流速与流向。此类仪器利用声波的多普勒效应，即声波经海水内颗粒物散射后可覆盖一定深度范围。本次布放依托固定式平台完成。本次布放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开展质量管控，并生成符合标准的衍生数据产品。
