The ROV SuBastian was used to conduct imagery transects on 20 dives across 16 stations, including 12 quantitative transects within the Cape Range Canyon. No quantitative transects were conducted in the Cloates Canyon due to delays caused by poor weather. SuBastian is equipped with a Sulis Subsea Z70 deep sea science camera, with 4K UHD 2160p optics and sensors for temperature, depth, conductivity and oxygen. The quantitative transects were run for 500 m upslope, ideally at a speed of 0.3 knots and an altitude of 2 m above the seafloor or rock walls. Still images were acquired every 5 seconds, with additional frames added manually as required. Still images from most transects were primarily annotated onboard using the RV Falkor’s private instance of SQUIDLE+, with some post-survey annotation conducted using the public instance of Squidle+ (http://squidle.org/). {"type": "Polygon", "coordinates": [[[111.1126, -23.9001], [114.5047, -23.9001], [114.5047, -20.9138], [111.1126, -20.9138], [111.1126, -23.9001]]]} 111.1126 114.5047 -23.9001 -20.9138 Imagery Marine ROV Link to the Image Catalogue documentDigital HTML Unnamed resource documentDigital License Graphic PNG Unnamed resource documentDigital HTML
