The Ocean Sonics icListen HF Hydrophone 1252 was deployed on 2019-09-17 at Barkley Canyon. Barkley Canyon is a submarine canyon located on the continental shelf and slope break. Features include exposed gas hydrates and their associated ecosystems. Accumulation and movement of sediment, upwelling, and plankton blooms are studied in this area. This device is a Hydrophone. Hydrophones are devices containing transducers that convert underwater sound waves into electrical signals. They are acoustic instruments that can process data while they are being collected to produce calibrated waveform data. Hydrophones are typically used to study vocalizations of marine mammals, ship traffic and ambient noise. It was deployed on a fixed platform. Data from this deployment were archived and made available through Ocean Networks Canada's Oceans 2.0 digital infrastructure, with quality assurance and derived data products following established practices.
