The Nortek Aquadopp Profiler A3P9315 AQD14501 was deployed on 2021-08-18 at Wally Land. Wally Land is a location within Barkley Canyon gas hydrate field, where hydrate dynamics are observed. This device is a Acoustic Doppler Current Profiler 2 MHz. Acoustic Doppler Current Profilers are hydroacoustic instruments, similar to sonars. ADCPs measure current speed and direction at multiple predetermined depths simultaneously. ADCPs use the Doppler effect of sound waves that are scattered by particles in seawater over a depth range. 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.
