Boundary Pass Current Meter Deployed 2013-10-11

The Nortek Aquadopp Current Meter A3L5377 AQD8386 was deployed on 2013-10-11 at Boundary Pass. Boundary Pass is a strait located along the boundary between Washington State and British Columbia. It connects Haro Strait with 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 Aquadopp海流计（Current Meter）A3L5377与AQD8386于2013年10月11日部署在边界水道（Boundary Pass）。边界水道是坐落于华盛顿州与不列颠哥伦比亚省交界地带的海峡，连接哈罗海峡（Haro Strait）与乔治亚海峡（Strait of Georgia）。该设备为海流计，声学海流计（Acoustic Current Meters, ACM）借助多普勒效应测量海流的流速与流向。Aquadopp海流计的传感器头部集成3个声学换能器、倾斜传感器、温度传感器与压力传感器。该仪器通过发射短脉冲声波，随后监听其回波以测量音调或频率的变化，基于该变化可推算海流流速。本次部署采用固定平台搭载设备。本批次采集的数据已完成存档，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，相关数据经过质量管控，并遵循既定流程生成衍生数据产品。
