Strait of Georgia East Current Meter Deployed 2014-03-09

The Nortek Vector Current Meter 4897 was deployed on 2014-03-09 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.

Nortek Vector 4897型海流计（Nortek Vector Current Meter 4897）于2014年3月9日部署于乔治亚海峡东部海域（Strait of Georgia East）。乔治亚海峡东部海域指乔治亚海峡的东部区域。该设备为海流计，声学海流计（Acoustic Current Meters, ACM）借助多普勒效应（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、一个倾角传感器、温度传感器与压力传感器。该仪器发射一段短声脉冲，随后接收其回波以测量音调或频率的变化，通过音调变化即可推算海流流速。本次部署中，设备搭载于固定平台之上。此次部署获取的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外开放，相关数据遵循既定行业规范完成质量管控，并生成了符合标准的衍生数据产品。
