SX90 sonar data in the Eastern Canadian Arctic: 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 Eastern Canadian Arctic. The sonar was operated during a 3 hours opportunistic survey offshore the Labrador coast on July 22nd and during a 18.75 hours opportunistic survey on July 30th. The sonar transducer is 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 (horizontal) 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.

Purpose

As part of the CCGS Amundsen 2011 summer expedition in the Canadian Arctic, the SX90 side-scan fisheries sonar was operated opportunistically during two iceberg mapping periods to better understand the capabilities and limitations of the sonar. One tabular iceberg was detected on July 22nd offshore the Labrador coast, and a portion of the Peterman tabular iceberg was approached on July 30th in Lancaster Sound. The purpose of this study was to use the two icebergs as targets to evaluate the maximum detection range and the accuracy of depth estimates by the SX90 sonar.
