Patricia Bay Current Meter Deployed 2010-12-12

The Nortek Aquadopp Current Meter 1176 was deployed on 2010-12-12 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（Nortek）Aquadopp 1176型海流计于2010年12月12日部署在温哥华岛南端萨尼奇湾（Saanich Inlet）内的帕特里夏湾（Patricia Bay）。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（Doppler Effect）测量水流的速度与方向。Aquadopp系列海流计的传感器头内置3个声学换能器、一个倾斜传感器、一个温度传感器及一个压力传感器。该仪器通过发射短脉冲声波并接收回波，检测音调或频率的变化，以此推算水流流速。本次部署采用固定平台开展。本批次部署获取的相关数据已完成归档，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规范完成质量保证与衍生数据产品的制作。
