Strait of Georgia East Current Meter Deployed 2016-10-07

The Nortek Vector Current Meter 4896 was deployed on 2016-10-07 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 metres 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 2.0 digital infrastructure, with quality assurance and derived data products following established practices.

Nortek Vector 4896型海流计（Nortek Vector Current Meter 4896）于2016年10月7日部署于乔治亚海峡东部海域。乔治亚海峡东部指乔治亚海峡的东部片区。该设备属于海流计范畴，声学海流计（Acoustic Current Meters, ACM）依托多普勒效应测量海流的流速与流向。Aquadopp海流计的传感器探头集成了3个声学换能器、1个倾斜传感器、1个温度传感器以及1个压力传感器。该仪器先发射一段短声波脉冲，随后监听回波以获取音调或频率的变化量，通过该变化量即可推算海流的流速。本次部署搭载于固定式平台。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 2.0数字基础设施对外开放共享，所有数据均遵循既定规范开展质量管控，并产出标准衍生数据产品。
