This dataset is a compilation product of all publicly available surveyed bathymetry within the Australian Marine Parks (AMPs, 2023 boundaries), merged into a single multi-resolution composite per AMP. The data was compiled 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. This compilation of bathymetry data was the first step in generating geomorphometry classifications (see https://metadata.imas.utas.edu.au/geonetwork/srv/eng/catalog.search#/metadata/40e9283b-d4ed-4176-8fe6-112b8697003f for derived geomorphometry maps).
Bathymetry data was collated from AusSeabed data holdings (https://portal.ga.gov.au/persona/marine), the WA Bathymetry Portal (https://dot-wa.maps.arcgis.com/apps/webappviewer/index.html?id=d58dd77d85654783b5fc8c775953c69b), the Australian Ocean Data Network (https://portal.aodn.org.au/) and other existing public data repositories. A single multi-resolution bathymetry mosaic, and associated multi-resolution hillshade mosaic, was generated for each AMP.
Data is supplied as a single Web Map Service of bathymetry on hillshade for the mapped regions. Data is available for download as (1) bathymetry, and (2) hillshade, Geotiff files for each AMP.
The table below indicates the Parks included in this data package, and the percent coverage of bathymetric data for each. Parks not expressly listed below had no publicly accessible bathymetry data available from the sources listed in the 'lineage' section below. This dataset was last updated on 06/03/2025 and represents all public bathymetry data intersecting AMPs that could be located as of that date.
