This dataset provides geomorphic features of the Australian Marine Parks (2022). The data was generated by Seamap Australia as part of an Our Marine Parks (Parks Australia) project with funding from the Australian Government to improve knowledge relating to classification of the Australian Marine Parks real estate. Bathymetry data was collated from existing AusSeabed data holdings and compiled into multi-resolution bathymetry mosaics for each Park. All publicly available bathymetry data as at 30th June 2022 was included. The Whitebox tools package in R was used to calculate geomorphometry using the geomorphron function. Prcoessing for each Park was addressed manually, with search distances and slope thresholds adjusted between Parks depending on quality and resolution of bathymetry data, and characteristics of the seafloor. Geomorphons were classified into geomorphic features using the Dove et al (2020) Seabed Morphology Features Glossary. These geomorphic units provide a consistent way to classify the seabed and may be used in combination with visual validation methods to develop benthic habitat maps. Data is supplied as a Web Map Service of geomorphic features overlaid on hillshade for the mapped regions. Data is available for download as a zipped package of geotiffs with accompanying hillshade. ESRI .lyr file and QGIS .sld files are supplied for display in desktop GIS. All Parks with 25% or more bathymetry coverage were included in processing. The table below indicates the Parks included in this data package, and the percent coverage of bathymetry/geomorphic data for each.

This data contains information about the distribution of seagrass around the Australian coastline. It was prepared by Dr. Hugh Kirkman (CSIRO Division of Fisheries) from a review of published and unpublished sources, and updated by Dr. Ian Hahmdorf, (Bureau of Rural Sciences). General info: CAMRIS, standing for the Coastal and Marine Resources Information System, is a small-scale spatial analysis system developed in collaboration by several divisions of Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO), as part of the CSIRO Coastal Zone Program. CSIRO Division of Wildlife and Ecology was the custodian of the 'coastal' subset of the Australian Resources Information System (ARIS). Coastal ARIS became the core dataset of the CAMRIS project. The Coastal ARIS database was developed from a coastal inventory developed by Galloway et al. This inventory contained relatively large scale data including landform, geology, vegetation, soil, land use, climate and population information for each of 3027 3x10km sections around the coastline of mainland Australia and Tasmania, but excluding offshore islands.
This database contains information about the distribution of 10 different types of sea floor sediment in the Australian region. It was derived from data collected and mapped by the Ocean Sciences Institute, University of Sydney.
