SX90 sonar data in the Beaufort Sea: 2011
The data set is composed of raw files recorded with the Kongsberg Maritime SX90 long-range, low frequency (20-30 kHz) fisheries sonar during the CCGS Amundsen 2011 summer expedition in the Beaufort Sea. The sonar was operated during 4 dedicated surveys (109 hours) and during 258 hours of opportunistic survey, from 27 August to 3 October. The sonar transducer was lowered 2.5 feet below the hull through a gate-valve. The cylindrical 256-elements transducer allows both a horizontal and a vertical sound transmission, and the omni-directional sonar beam can be tilted from +10 to -60 degrees to scan a large portion of the water column. The raw acoustic data were saved onto an external drive and print screens of interesting targets (fish schools and/or marine mammals) were recorded.
