Bullseye Acoustic Doppler Current Profiler 55 kHz Deployed 2018-07-30

The Nortek Signature55 Current Profiler 0056 was deployed on 2018-07-30 at Bullseye. Bullseye is a location at Clayoquot Slope, where gas hydrates, seafloor cold seeps, and hydrate dynamics are observed. This device is a Acoustic Doppler Current Profiler 55 kHz. 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.
