                                 area.
                                 The detailed check results can be found in Appendix A: Survey Control Checks.

                                 7.1     Method used to reduce depths to datum
                                 Depths were determined relative to the GDA2020 ellipsoid and reduced to AHD by use of
                                 AUSGeoid2020.

                                 The vessel used for this survey was a 3.3m Yamaha Waverunner PWC, SandXplorer. This vessel
                                 is commercially registered through AMSA in 2C survey. The transducer is mounted on a fixed
                                 mount to the starboard side aft with a GNSS antenna pole located directly above, not requiring
                                 any horizontal offsets. Offset to the transducer from the antenna is fixed at 1.335m.
