  • This collection contains satellite imagery or Earth Observations from space created by Geoscience Australia. Among others, the collection includes data from various satellite sensors including Landsat Thematic Mapper and Multi-Spectral Scanner, Terra and Aqua MODIS.

  • Total magnetic intensity data measures variations in the intensity of the Earths magnetic field caused by the contrasting content of rock-forming minerals in the Earths crust. The data are collected on airborne geophysical surveys conducted by Commonwealth, State & NT Governments and the private sector.

  • Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Department of Environment and Natural Resources within the Northern Territory Government (DENR) undertook collaborative seabed mapping surveys (GA0351/SOL6187, GA4452/SOL6432 and combined GA0361 & GA0362) in the Darwin-Bynoe Harbour region between 2015 and 2018. This seabed mapping project forms a core component of a four-year collaborative research program between DENR, GA and AIMS, which was funded by the INPEX-operated Ichthys LNG Project to DENR, with co-investment by GA and AIMS. The purpose of the program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions through the collation and acquisition of baseline data that enable the creation of habitat maps to better inform marine resource management decisions. Mapping and sampling in the survey area utilised multibeam echosounders, sub-bottom profilers, underwater cameras and grab samplers. In total, this data package extends over an area of 1978 km2, including 1754 km2 mapped using multibeam echosounders, during four marine surveys over 247 days. The baseline environmental data acquired in this program provides new insights into the marine environments of the Greater Darwin and Bynoe Harbour region, will inform future environmental assessments in the region and help build our knowledge of seabed features and processes in tropical northern Australia.

  • On behalf of Australia, and in support of the Malaysian accident investigation, the Australian Transport Safety Bureau (ATSB) led search operations for missing Malaysian Airlines flight MH370 in the Southern Indian Ocean. Geoscience Australia provided advice, expertise and support to the ATSB to facilitate marine surveys, which were undertaken to provide a detailed map of the sea floor topography to aid navigation during the underwater search. Prior to the Phase 1 bathymetric survey, very little was known about the sea floor in the MH370 search area, as few marine surveys have taken place in the area. Existing maps of the sea floor were coarse, having been derived from satellites and only providing a general indication of water depth. Before the underwater search for MH370 could begin, it was necessary to accurately map the sea floor to ensure that the search was undertaken safely and effectively. Survey vessels spent months at sea, scanning the sea floor with multibeam sonar and side scan sonar to gather detailed, high-resolution data. This collation of datasets on the National Computational Infrastructure contains the high resolution raw and processed data acquired during Phase 2 of the search for MH370 as received by third party operators. The Phase 2 underwater search data was acquired by multiple vessels, including the Fugro Equator, Fugro Supporter, Fugro Discovery, Havila Harmony, Dong Hai Jiu 101 and Go Phoenix. Surveys were conducted using towed and autonomous underwater vehicles between September 2014 to January 2017, collecting over 121,000 square kilometres of high resolution data in the search area.

  • The AGSO Yearbooks retained the format of the BMR Yearbooks, the title change merely following the renaming of the Bureau to the Australian Geological Survey Organisation in 1992. The series ended in 1994, when AGSO became part of the Department of Primary Industries and Energy and information on its activities was incorporated into DPIE Annual Reports.

  • The airborne geophysics collection contains individual survey grids of geophysical data, including Total Magnetic Intensity, Bouguer Gravity, Gamma-ray spectrometry (radiometrics - K, Th, U) and elevation. The grids were derived from publicly available government- and company-acquired airborne magnetic and radiometric surveys, airborne gravity, and airborne gravity gradiometry surveys in Australia and its surrounding marine area.

  • This collection contains all national level bathymetry grids held by Geoscience Australia (GA) dating back to survey data obtained since 1993. <b>Value: </b>Bathymetry data is used for a wide range of marine applications including: navigation, environmental assessment, jurisdictional boundaries, resource exploration. <b>Scope: </b>Data holdings lying within the offshore area of Australia, including international waters. <b>To access the AusSeaBed Marine Data Portal</b> use the following link: <a href="https://portal.ga.gov.au/persona/marine#/">https://portal.ga.gov.au/persona/marine#/</a> <b>To view the entire collection click on the keyword "HVC_146413" in the below Keyword listing</b>

  • Geoscience Australia's Oracle organic geochemical database comprises analytical results for samples relevant to petroleum exploration, including source rocks, crude oils and natural gases from both onshore and offshore basins. The data is non-confidential and available to the petroleum industry, research organisations and the public. The data are produced by a wide range of destructive analytical techniques conducted on samples submitted by industry under legislative requirements, as well as on samples collected by research projects undertaken by Geoscience Australia or other government agencies or institutions. Some of the results have been generated by Geoscience Australia’s laboratory, whereas other data is compiled from service company reports, well completions reports and published papers. <b>Value: </b>These data comprise the raw organic geochemistry values generated for Australian source rocks, crude oil and natural gases and is the only public comprehensive database at the national scale. The raw data are used as input to other studies, such as petroleum systems modelling, resource assessments and national mapping projects. Derived datasets and value-add products are created based on calculated values and interpretation to provide information on the subsurface petroleum prospectivity of the Australian continent. The data collection aspires to build a national-scale understanding of Australia’s oil and gas resources. <b>Scope: </b>This data collection is useful to government for evidence-based decision making on natural energy resources and the petroleum industry for de-risking conventional and unconventional exploration programs. Results for many of the oil and gas samples held in the Australian National Offshore Wells Data Collection are included in this database. <b>To view the entire collection click on the keyword "HVC 144673" in the below Keyword listing</b>

  • Delineation of Australia's domestic and international maritime limits and boundaries.
