Towed Video transects + Digital Stills SloVid Digital Stills CTD BRUVS SBRUVS Echo Sounder Wave Glider Sediment Samples (CSIRO) ARP7 Reefs Trip 6823 To characterise the status of and natural temporal variability in sessile benthic biota and associated fish communities, across the plateau areas around Browse Island and its deeper waters. The project will provide a reference dataset, updated seasonally for two years, for the status of key biodiversity indicator habitats around Browse Island.

Bathymetry flythrough of Perth Canyon using data acquired by Schmidt Ocean Institute in 2015 on RV Falkor (University of Western Australia et al.). The flythrough highlights geomorphic features mapped by Geoscience Australia, including landslides, escarpments and bedform fields and biodiversity associated with the canyon (benthic and pelagic). Produced as a science communication product for the Marine Biodiversity Hub (National Environmental Science Program). This research is supported by the National Environmental Science Program (NESP) Marine Biodiversity Hub through Project D1.

Flythrough movie showing the bathymetry of the shelf along the coast of southeast Tasmania, highlighting rock reefs as benthic habitats. The bathymetric image is derived from multibeam sonar collected in 2008 and 2009 using a 300 kHz Simrad EM3002 system on RV Challenger and gridded at 3 - 4 m resolution. Key features on the shelf include low relief (< 5 m) reefs on the outer shelf of Freycinet Peninsula and inner shelf of Tasman Peninsula, high relief (50-90 m) reefs surrounding Hippolyte Rocks, and extensive fractured reefs around The Friars to the south of Bruny Island. All reefs provide hard substrate for kelp gardens and diverse sponge communities. The southeast Tasmanian shelf is a study site for the Marine Biodiversity Research Hub, funded through the Commonwealth Environment Research Facilities (CERF) programme. Survey work was carried out as a collaboration between Geoscience Australia and University of Tasmania (Institute for Marine & Antarctic Studies). Further information is provided in GA Record 2009/43.

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.
