Geoscience Australia carried out marine surveys in south-east Tasmania in 2008 and 2009 (GA0315) to map seabed bathymetry and characterise benthic environments through observation of habitats using underwater towed video. Data was acquired using the Tasmania Aquaculture and Fisheries Institute (TAFI) Research Vessel Challenger. Bathymetric mapping was undertaken in seven survey areas, including: Freycinet Pensinula (83 sq km, east coast and shelf); Tasman Peninsula (117 sq km, east coast and shelf); Port Arthur and adjacent open coast (17 sq km); The Friars (41 sq km, south of Bruny Island); lower Huon River estuary (39 sq km); D Entrecastreaux Channel (7 sq km, at Tinderbox north of Bruny Island), and; Maria Island (3 sq km, western side). Video characterisations of the seabed concentrated on areas of bedrock reef and adjacent seabed in all mapped areas, except for D Entrecastreaux Channel and Maria Island. The GA0315_SETasi folder contains video footage; the excel file is the video characterisation data. Underwater video footage represents raw data. Video characterisation dataset include percent cover of substate. This dataset is a contribution to the CERF Marine Biodiversity Hub.

This data contains spatial and contextual information about Australian Marine Parks proclaimed under the Commonwealth Government's Environment Protection and Biodiversity Conservation Act 1999, which are managed by Parks Australia, with the addition of Heard Island and McDonald Islands Marine Reserve, which is managed by the Australian Antarctic Division. The Australian Marine Parks include the North, North-west, South-west, South-east and Temperate East Networks, the Coral Sea Marine Park, and the Indian Ocean Territories Marine Parks. These parks were established in Commonwealth waters consistent with the Australian Government’s commitment to develop a National Representative System of Marine Protected Areas.More information can be found at:Heard Island and McDonald Islands Marine Reserve – Australian Antarctic ProgramThis dataset does not include marine protected areas in other Australian jurisdictions (e.g. the Great Barrier Reef Marine Park, State/Territory marine parks), or terrestrial protected areas with marine components (e.g. Pulu Keeling National Park). More information can be found at:Australian Marine Parks | Parks AustraliaMore information about the zoning and rules for activities for each of the networks can be found here:Coral Sea: Coral Sea Marine Park | Australian Marine Parks | Parks AustraliaIndian Ocean Territories: Indian Ocean Territories Marine Parks | Australian Marine Parks | Parks AustraliaNorth network: North Marine Parks Network | Australian Marine Parks | Parks AustraliaNorth-west network: North-west Marine Parks Network | Australian Marine Parks | Parks AustraliaSouth-east network: South-east Marine Parks Network | Australian Marine Parks | Parks AustraliaSouth-west network: South-west Marine Parks Network | Australian Marine Parks | Parks AustraliaTemperate East: Temperate East Marine Parks Network | Australian Marine Parks | Parks AustraliaSince this dataset was originally published in 2018 there have been the following updates:1. A technical amendment was made on the basis of user feedback (April 30th 2019). Macquarie Island was the only marine park affected by this amendment. The area calculation for Macquarie Island Marine Park was previously under reported by 483km2. This will have affected statistical analyses that used the calculated area (KM2) as an input. This amendment is superseded by item 4 below.2. A zoning boundary error identified at West Island in Ashmore Reef Marine Park was corrected (March 2022).3. Two new Australian Marine Parks were added to this dataset in March 2022; Christmas Island Marine Park and Cocos (Keeling) Islands Marine Park.4. The addition of the expanded Macquarie Island Marine Park which came into effect on 1 July 2023, replacing the boundaries of the original marine park proclaimed in 1999.5. The expanded Heard Island and McDonald Islands Marine Reserve took effect on 24 January 2025. 6. The South-east Marine Parks zoning updates under the new management plan came into effect on 13 February 2025.

This study was carried out in Ningaloo Marine Park and included both Commonwealth and Western Australian State Waters. Surveys were conducted at three sites adjacent to existing State marine sanctuary zones, Mandu Mandu, Point Cloates, and Point Maud. These areas were selected to test the spatial variation of benthic communities along a north-south gradient at the 10-100 km scales, (ie. 10km scale within sites and 100km scale between sites). At each survey site, fifteen transects at five depth zones from the seaward edge of Ningaloo Reef were surveyed using a towed video camera system (Towvid). Simultaneously, BRUVS (TM) (Baited Remote Underwater Video Stations) were deployed at various point locations in the study area. BRUVS (TM) deployments were opportunistic, weather dependent and varied among sites, three deployments at Mandu Mandu, six at Point Cloates and nine at Point Maud. The study was undertaken for the Commonwealth Government Department of the Environment and Heritage, to begin a process of describing deepwater biodiversity in the Ningaloo Marine Park and to address a lack of such information seaward of Ningaloo Reef crest. Another aim of the project was to identify any areas of high biodiversity in both Commonwealth and State waters of the park. This information would be used to assist in identifying potential sanctuary zones to preserve the areas of high biodiversity that are considered to be relatively important within the reserve. The study sites chosen were adjacent to existing State marine sanctuary zones.

This dataset is part of a broader survey carried out by EGS Survey Pty Ltd onboard the survey vessel RV Bold Explorer (RV BE) during the SUBCO Subsea Cable Network (SSCN) cable route survey. The area is confined to the data within the Apollo Marine Park and was acquired between 24th Februarfy 2024 and the 5th March 2024. The SUBCO Subsea Cable Network (SSCN) comprises a trunk route between Perth (Western Australia) and Sydney (New South Wales) with branches to Garden Island (Western Australia), Adelaide (South Australia), and Torquay (Victoria). EGS Australia was contracted by OMS to supply hydrographic, geophysical, and geotechnical survey services, to provide data for engineering, construction, and subsequent maintenance of the SSCN Segment 2-C (BU TQW up to 206.3m WD). The primary purpose of the survey is to determine a viable and secure route for the cable system that is clear of excessive slopes (>6°), sea floor conditions that will adversely affect ploughing and burial of the cable, and obstacles such as rock outcrops, cable spans, existing cables, pipelines, shipwrecks etc. The SSCN Segment 2-C (BU TQW up to 206.3m WD) survey comprised an investigation of bathymetry, seabed features and shallow geology along the proposed route.
