Strait of Georgia Central Current Meter Deployed 2012-02-25

The Nortek Vector Current Meter 4820 was deployed on 2012-02-25 at Strait of Georgia Central. Strait of Georgia Central is a central area in 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2012年2月25日部署于乔治亚海峡中部（Strait of Georgia Central）。乔治亚海峡中部为乔治亚海峡（Strait of Georgia）的中心区域。该设备为海流计，声学海流计（Acoustic Current Meters, ACM）利用多普勒效应（Doppler Effect）测量水流速度与流向。Aquadopp型海流计的传感器探头集成3个声学换能器、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高或频率变化，通过音高变化推算水流流速。本次部署的设备搭载于固定式平台。本批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数字基础设施对外提供，所有数据均遵循既定规范完成质量管控，并生成了标准化衍生数据产品。
