Fraser River Delta Upper Slope Profiling Sonar Deployed 2019-09-15

The Imagenex 881A Profiling Sonar 5715 was deployed on 2019-09-15 at Fraser River Delta Upper Slope. This site is located on the upper slope of the Fraser River delta, where depth is approximately 100 metres. This device is a Profiling Sonar. Profiling sonars are devices used in underwater profiling where quantitative measurements are required. A profiling sonar transmits a very narrow, conical beam that generates one point per ping, providing very high resolution. Reflected signals, or echoes, are recorded and analyzed in order to develop an image of scanned area that includes information on the range between the sonar and the scanned object. 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.
