Marine ecosystems, substrates and geomorphic features have been classified using multibeam echosounder and marine lidar data for the Commonwealth Solitary Islands Marine Park (SIMP). This package contains three datasets, including: ‘marine ecosystems and substrates’, which defines reef and sediment areas delineated by depth intervals (10 m increments); ‘marine geomorphology’, which defines seabed landforms; and ‘bathymetry sources’, which outlines the source coverages of the input bathymetric mosaic. A bathymetry mosaic was generated using data sourced from the NSW DCCEEW bathymetry mosaic (NSW DCCEEW, 2023), updated with multibeam echosounder data collected within SIMP in 2023. Seabed ‘landforms’ were derived from the bathymetry mosaic using the Seabed Landforms Classification Toolbox (Linklater et al. 2023), which characterises seabed morphology to classify features as ‘reefs’, ‘peaks’, ‘scarps’, ‘plains’ and ‘depressions and channels’. Landform features were subsequently grouped into hard and soft substrate features and labelled to conform to the NESP Natural Values Common Language (Hayes et al. 2021) and Seamap substrate classification scheme (Butler et al. 2017). This work was conducted for and funded by Parks Australia. References: Butler, C., Lucieer, V., Walsh, P., Flukes, E. and Johnson, C. (2017).
