Maintenance and Update Frequency: asNeeded Statement: While AusSeabed aims to publish data based on the requirements stated in the AusSeabed multibeam guidelines (version 1, https://australian-multibeam-guidelines.github.io), we will also publish interim products (version 0) that are currently available, but have not yet been standardised (version 1). Users should be aware that V1 products will always supersede V0 products. This dataset was produced using CARIS HIPS & SIPS and the AusSeabed-recommended processing methodology as follows. These surfaces are a 5 to 128 metre Combined Uncertainty and Bathymetry Estimator (CUBE) surfaces with depth, position, density and uncertainty preserved from the original surface.
