The Adelaide Reference Surfaces bathymetry survey was acquired for the Australian Hydrographic Office (AHO) during the period 4 Sep 2020 – 16 Sep 2020. This surface was created from a contracted national reference survey in Gulf St Vincent SA, collected for the purpose of calibrating multibeam echosounders. It was conducted for the Australian Hydrographic Office as part of the Hydroscheme Industry Partnership Program, acquired using Kongsberg EM 2040 multibeam echosounder and Kongsberg EA440 singlebeam echosounder, and processed using Caris HIPS & SIPS. Separate grids in 1m resolution are provided for the 2 surveyed sites within this survey area in MSL, LAT and Ellipsoid vertical datum. The dataset was then exported as a 1m resolution, 32 bit floating point GeoTIFF grid of the survey area. This dataset is not to be used for navigational purposes.
