Juan de Fuca Strait Current Meter Deployed 2014-10-09

The Nortek Aquadopp Current Meter A3L5380 AQD8375 was deployed on 2014-10-09 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 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.

Nortek Aquadopp海流计（型号A3L5380、AQD8375）于2014年10月9日部署于胡安德富卡海峡（Juan de Fuca Strait）。胡安德富卡海峡是连接萨利希海（Salish Sea）与太平洋的大型海域。该设备属于海流计范畴，声学海流计（Acoustic Current Meters, ACM）依托多普勒效应（Doppler Effect）测量海流的流速与流向。Aquadopp海流计的传感器探头内置3个声学换能器、1个倾斜传感器、温度传感器与压力传感器。该仪器发射短脉冲声波，随后接收回波以检测音调（频率）的变化，通过该音调变化即可推算海流流速。本次部署将设备安置于固定平台之上。本次部署获取的相关数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外开放，其数据质量管控与衍生数据产品均遵循既定行业规范。
