  • This resource includes bathymetry data acquired during the Southern Gulf of Carpentaria bathymetry survey using Simrad EM300 and Reson Seabat 8101 multibeam sonar systems. Southern Gulf of Carpentaria bathymetry survey (GA0276) was led by Dr. Peter Harris (Geoscience Australia) aboard the Marine National Facility's research vessel Southern Surveyor, from the 23rd of March to the 13th of April 2005. The primary objective of the expedition was to map submerged reefs to ascertain their geomorphic nature and document the benthic communities and fauna. This dataset contains four 4m to 7m resolution 32-bit floating point geotiff files of the bathymetry in five study areas and transits, derived from the processed EM300 and Reson 8101 bathymetry data, using CARIS HIPS and SIPS software.

  • Seabed mapping data collected using a Kongsberg 2040C multibeam sonar system aboard research vessel MVYolla including bathymetry (2 metre resolution), backscatter (1metre resolution), watercolumn and preliminary hard bottom classification. Seabed mapping in Apollo Marine Park with 114 square kilometres of continuous seabed mapping conducted by Deakin University in partnership with iXblue for Parks Australia.

  • The Casey Station Bathymetry Survey was conducted last summer from December 2014 to February 2015. This collaborative survey was undertaken by Geoscience Australia, the Royal Australian Navy and the Australian Antarctic Division, using the AAD's workboat the RV Howard Burton. The survey goal was to acquire high resolution bathymetry data to improve our understanding of the seafloor using multibeam sonar. The bathymetry data collection will be supplemented by physical sampling of the seafloor sediments and video recordings of the biological communities living in the seafloor. The survey will cover areas that haven't been charted during the 2013 Casey Survey and are frequently used by the RSV Aurora Australis. Improving our understanding of the seabed environment in these shallow coastal waters will ultimately lead to a better environmental management of the Australian Antarctic Territory. The data will also help the RAN to develop more accurate navigation charts therefore reducing the risk to maritime operation in the region.

  • Geoscience Australia conducted a hydrographic and seafloor characterisation survey nearshore from Davis Station in the Australian Antarctic Territory. The multibeam bathymetry data was acquired during January-February 2017 from the AAD workboat Howard Burton in the Vestfold Hills region. This survey is a component of the Australian Antarctic Program (AAP) and Project 5093 Hydrographic Surveying and Seafloor Characterisation Program (Chief Investigator: Ursula Harris, AAD). The objective of the survey was to map the seabed environment in shallow (<300 m) coastal waters for the compilation of nautical charts and acquire baseline data for environmental management, science, infrastructure and logistical operations. Data collected during the survey includes high-resolution multibeam bathymetry, backscatter, sediment samples, seafloor imagery and sub-bottom profiles. This dataset is a 32bit geotiff at 11 m resolution using EGM2008 vertical datum and EPSG:4326 coordinate system and produced from the processed EM3002D/ EM2040C Dual system bathymetry data. This dataset is published with the permission of the CEO, Geoscience Australia. Not to be used for navigational purposes.

  • The Petrel Sub-basin Marine Environmental Survey GA-0335 was acquired by the RV Solander during May 2012 as part of the Commonwealth Government's National Low Emission Coal Initiative (NLECI). The survey was undertaken as a collaboration between Geoscience Australia and the Australian Institute of Marine Science (AIMS) . The purpose was to acquire geophysical and biophysical data on shallow (less than 100m water depth) seabed environments within two targeted areas in the Petrel Sub-basin to support investigation for CO2 storage potential in these areas.

  • This resource includes bathymetry data acquired during the Arafura Marine Park bathymetry survey using Kongsberg EM300 multibeam sonar system. The Arafura Marine Park bathymetry survey (SS052005/GA0282); also known as Arafura Sea survey; was led by Geoscience Australia aboard the National facility research vessel Southern Surveyor from the 30th of April to the 27th of May 2005. The primary objective of the expedition was to collect seismic and oceanographic data, mapping the sea floor and taking geological samples over various habitats. Another objective was to collect baseline information on the biodiversity of a smaller region within the Arafura Sea. This V1 dataset contains two 5m and 8m resolution 32-bit floating point geotiff files of the new Arafura Marine Park bathymetry, derived from the processed EM300 bathymetry data, using CARIS HIPS and SIPS software. This dataset is not to be used for navigational purposes. This dataset is published with the permission of the CEO, Geoscience Australia.

  • The Petrel Sub-basin CO2 storage 2D seismic survey GA-0336, was acquired by the MV Duke in the Bonaparte Bay, NW Australia for Geoscience Australia between the the 3rd of May to the 24th of June 2012. This survey was part of the Australian government's National Low emission Coal Initiative (NLECI).The purpose was to acquire geophysical data on shallow water (less than 120m water depth) in the Petrel sub-basin to support investigation for CO2 storage potential in the area. Multibeam bathymetry data was acquired by the vessel at the same time as the seismic data. This bathymetry dataset consist of the high resolution bathymetry grids (2m) of all the swath data acquired by the MV Duke.

  • This is a compilation of bathymetry surveys GA-4415 and GA-0348. GA-4415 survey was conducted by the Royal Australian Navy (RAN) and the Australian Antarctic Division (AAD) onboard the RAN vessel Wyatt Earp in 2013/2014, while GA-0348 survey was a collaboration between Geoscience Australia (GA) , the Royal Australian Navy and Australian Antarctic Division acquired by the AAD workboat Howard Burton during December 2014 to February 2015. The survey goal was to acquire high resolution bathymetry data to improve our understanding of the seafloor using multibeam sonar. The bathymetry data collection will be supplemented by physical sampling of the seafloor sediments and video recordings of the biological communities living in the seafloor. The survey covers areas that are frequently used by the RSV Aurora Australis. Improving our understanding of the seabed environment in these shallow coastal waters will ultimately lead to a better environmental management of the Australian Antarctic Territory. The data will also help the RAN to develop more accurate navigation charts therefore reducing the risk to maritime operation in the region.

  • Geoscience Australia carried out marine surveys in Jervis Bay (NSW) in 2007, 2008 and 2009 (GA303, GA305, GA309, GA312) to map seabed bathymetry and characterise benthic environments through colocated sampling of surface sediments (for textural and biogeochemical analysis) and infauna, observation of benthic habitats using underwater towed video and stills photography, and measurement of ocean tides and wavegenerated currents. Data and samples were acquired using the Defence Science and Technology Organisation (DSTO) Research Vessel Kimbla. Bathymetric mapping, sampling and tide/wave measurement were concentrated in a 3x5 km survey grid (named Darling Road Grid, DRG) within the southern part of the Jervis Bay, incorporating the bay entrance. Additional sampling and stills photography plus bathymetric mapping along transits was undertaken at representative habitat types outside the DRG. The dataset contains 11 bathymetry grids of Jervis Bay survey area produced from the processed EM3002 bathymetry data using the CARIS HIPS and SIPS software. Please see the metadata for detailed informaiton.

  • <p>This resource contains multibeam bathymetry data for Bynoe Harbour collected by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Northern Territory Government (Department of Environment and Natural Resources) during the period between 3 and 27 May 2016 on the RV Solander (survey SOL6432/GA04452).
