Folger Pinnacle Current Meter Deployed 2010-08-23

The Nortek Aquadopp Current Meter ASL2552 AQD2565 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 Current Meter. Acoustic Current Meters (ACM) measure current speed and direction, using the Doppler Effect. Aquadopp current meters have a sensor head that contains 3 acoustic transducers, a tilt sensor, a temperature sensor and a pressure sensor. The instrument transmits a short pulse of sound, and then listens to its echo to measure the change in pitch or frequency. The change in pitch can determine the velocity of the current. 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.

型号为ASL2552 AQD2565的Nortek Aquadopp流速仪（Current Meter）于2010年8月23日部署于福尔杰尖峰（Folger Pinnacle）。福尔杰尖峰是福尔杰航道（Folger Passage）内一处孤立的柱形地貌，该区域已观测到丰富的生物多样性与海岸生态系统。该设备为声学流速仪（Acoustic Current Meters，ACM），依托多普勒效应测量水流流速与流向。Aquadopp流速仪的传感器探头内置3个声学换能器、一个倾斜传感器、一个温度传感器与一个压力传感器，仪器通过发射短促的声波脉冲并接收回波，检测音调或频率的变化，进而推算水流速度。本次部署搭载于固定平台之上。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开展质量管控，衍生数据产品的生成亦符合统一行业标准。
