The area is confined to the data within the Nelson Marine Park. The Survey team and client representative joined the RV Bold Explorer on 17th April 2024 at Fremantle Port, Australia. Following the embarkation of the survey team, equipment testing and commissioning was carried out. Calibration and verification of the DGPS positioning system and survey gyros onboard RV BE were performed while the vessel was alongside at Fremantle Port, Australia between 17th April and 18th April 2024. Prior to departure, tow sensors and hull-mounted sensors were wet tested. All systems were found to be operational. The RV Bold Explorer departed Fremantle Port, Australia and transited to the first site on 19th April 2024. The offshore calibration of shallow water multibeam echosounder (MBES) and USBL were performed on 19th April 2024 while the calibration of deep water MBES was carried out on 20th April 2024. The SSCN Segment 2-C survey comprised an investigation of bathymetry, seabed features and shallow geology along the proposed route. A subsequent geotechnical sampling programme was also executed.
