These parks span a range of settings, from near coastal and shelf habitats to abyssal plains. Parks Australia manages the park network through management plans that came into effect for all parks on 1 July 2018. Geoscience Australia is contributing to their management by collating and interpreting existing environmental data, and through the collection of new marine data.  \u201cEco-narrative\u201d documents are being developed for those parks, where sufficient information is available, delivering collations and interpretations of seafloor geomorphology, oceanography and ecology. Many of these interpretations rely on bathymetric grids and their derived products, including those in this data release.\n\n\nGeoscience Australia has developed a new marine seafloor classification scheme, which uses the two-part seafloor mapping morphology approach of Dove et al (2016). This new scheme is semi-hierarchical and the first step divides the slope of the seafloor into three Morphological Surface categories (Plain, <2\u00b0; Slope, 2-10\u00b0; Escarpment, >10\u00b0). This classification was applied to the portion of the Beaman and Spinnocia (2018) 30 m grid within the marine park. \n\n\nBeaman, R.J. and Spinoccia, M. (2018).
