The seafloor morphology mapping approach used to derive this dataset follows Geoscience Australia’s draft National Seafloor GeoMorphology (NSGM) mapping scheme (Nanson and Nichol, 2018). The NSGM scheme is an extension of the Dove et al. (2016) approach, which characterises the seafloor in two sequential parts: Part 1 maps the seafloor Morphology (shape) using bathymetry data, and Part 2 uses additional data to interpret seafloor Geomorphology for those mapped morphological shapes. Part 1 of the NSGM scheme was applied to the project dataset, and consists of three hierarchical levels: Province, Surface and Feature.
