Patricia Bay Current Meter Deployed 2012-08-11

The Nortek Vector Current Meter 4906 was deployed on 2012-08-11 at Patricia Bay. Patricia Bay is located in the Saanich Inlet, on the southern tip of Vancouver Island. 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 4906型海流计（Nortek Vector Current Meter 4906）于2012年8月11日部署于帕特里夏湾（Patricia Bay）。帕特里夏湾地处温哥华岛南端的萨尼奇湾（Saanich Inlet）内。该设备属于海流计类仪器，声学海流计（Acoustic Current Meters，ACM）依托多普勒效应（Doppler Effect）测量海流的流速与流向。Aquadopp型海流计的传感器探头集成3个声学换能器、一个倾斜传感器、温度传感器及压力传感器。此类仪器通过发射短脉冲声波并接收其回波，测量音调（频率）的变化量，进而以此推算海流流速。本次部署的设备搭载于固定式平台之上。本批次部署获取的原始数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外共享；所有数据均遵循既定行业规范完成质量管控，并衍生出配套的数据产品。
