Strait of Georgia East Current Meter Deployed 2024-03-15

The Nortek Vector Current Meter 4820 was deployed on 2024-03-15 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2024年3月15日部署于乔治亚海峡东部（Strait of Georgia East）。乔治亚海峡东部指乔治亚海峡的东部海域。该设备为海流计，声学海流计（Acoustic Current Meters, ACM）通过多普勒效应（Doppler Effect）测量海流的流速与流向。Aquadopp型海流计的传感器探头内置3个声学换能器、一个倾斜传感器、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或频率的变化，通过该变化可推算海流的运动速度。本次部署将设备固定于固定式平台之上。本次部署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数字基础设施对外开放，且遵循既定规范完成了质量管控与衍生数据产品的制作。
