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.

The AusSeabed Bathymetry Survey Acquisitions Coverage database contains polygon extents of bathymetry data acquisitions along with identifying attributes and contact details where the data is not held by Geoscience Australia. It is an important scientific resource that identifies data spanning coastal, continental shelf and deep sea locations. This dataset is live and will continue to be augmented as coverage details are supplied from AusSeabed collaborators who wish to share their knowledge of data availability to the broader marine community. The database is updated regularly and is made available via the AusSeabed Marine Data Portal using OGC compliant web services. Surveys/Data Acquisitions have been conducted by a wide range of organisations and countries, both inside and outside Australia's marine jurisdiction, using multiple systems and for various applications. Data coverages are published where the polygon extents intersects with Australia's marine jurisdiction, including the Australian Antarctic Territory. Each polygon in the layer contains metadata describing survey details. Note that polygons may not be representative of the true survey extent due to the data gridding process. For a list of source data contributions see Technical Lineage. Please note that this public coverage does not include information that has been provided to Geoscience Australia under a Restricted and Exclusive license. However, the additional restricted information is used during the computation of Australian marine jurisdiction’s Percent Mapped assessment.

This dataset represents the current extent of bathymetry compilation products delivered by Geoscience Australia as of June 2019. Compilation products have been generated from numerous data sources including survey data, lidar, interpolation and other depth data. Each polygon shows the extent of the compilation dataset, and attributes contain information regarding data sources, product details and access methods. Contributing individual survey data can be found in the AusSeabed Bathymetry Holdings dataset.
