Boundary Pass Current Meter Deployed 2020-10-28

The Nortek Aquadopp Current Meter A3L5380 AQD8375 was deployed on 2020-10-28 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.
