Patricia Bay Current Meter Deployed 2007-09-15

The Nortek Aquadopp Current Meter 1176 was deployed on 2007-09-15 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.

Nortek Aquadopp型1176号海流计于2007年9月15日在帕特里夏湾布放。帕特里夏湾位于温哥华岛南端的萨尼奇湾内。该设备为海流计。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型海流计的传感器探头内置3个声学换能器、1个倾斜传感器、1个温度传感器及1个压力传感器。该仪器发射短脉冲声波，随后接收回波以测量音调或频率的变化，通过该音调变化即可推算出海流流速。该海流计布设于固定式平台之上。本次布放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数字基础设施对外共享，其数据质控与衍生数据产品均遵循行业既定规范。
