Strait of Georgia East Current Meter Deployed 2023-03-17

The Nortek Vector Current Meter 4820 was deployed on 2023-03-17 at Strait of Georgia East. Strait of Georgia East refers to an eastern area of the Strait of Georgia. 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.

诺泰克Vector 4820型海流计（Nortek Vector Current Meter 4820）于2023年3月17日部署于乔治亚海峡东区（Strait of Georgia East）。乔治亚海峡东区指乔治亚海峡的东部海域。该设备属于海流计范畴，声学海流计（Acoustic Current Meters，ACM）借助多普勒效应测量海流的流速与流向。Aquadopp型海流计的传感器探头集成有3个声学换能器、1个倾斜传感器、1个温度传感器及1个压力传感器。此类仪器通过发射短脉冲声波并监听其回波，以测量音调或频率的变化，进而通过音调变化推算海流流速。本次部署的设备搭载于固定平台之上。本批次部署获取的数据已完成存档，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共享，其质量保证流程及衍生数据产品均遵循既定行业规程。
