    • AFSC/RACE/GAP/McConnaughey: Trawlex Chronic Effects: Side Scan Sonar Mosaic - Experimental tow in the mid-east region of CHPZ1.

    Metadata Updated: April 1, 2024

    Side-scan sonar images were collected using a Klein 2000 system and a 100/500-kHz towed ?sh that also contained a 3.5-kHz pro?ler source. A shipboard fathometer re- cording system was inoperable during the survey. The side-scan data were recorded digitally at a 10-kHz sample rate over a swath width of 100 m. Six swaths of 100-kHz data were anamorphosed, filtered, overlaid and projected to produce a spatially correct, georeferenced image of the seafloor with pixel resolution of 40 cm.
