Fraser River Delta Lower Slope Profiling Sonar Deployed 2013-10-23

The Imagenex 881A Profiling Sonar 3898 was deployed on 2013-10-23 at Fraser River Delta Lower Slope. This site is located on the lower slope of the Fraser River delta, where depth is approximately 150 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 2.0 digital infrastructure, with quality assurance and derived data products following established practices.
