  • GIS package attached to the final reports on activities in the Gawler - Eucla, TiTree, Wilkinkarra, Murchison and Paterson regions for the Palaeovalley Groundwater Project.

  • Airborne Electromagnetic data are being acquired by Geoscience Australia in areas considered to have potential for uranium or thorium mineralisation under the Australian Government's Onshore Energy Security Program (OESP). The surveys have been managed and interpreted by Geoscience Australia's Airborne Electromagnetic Acquisition and Interpretation project. In contrast to industry style deposit scale investigations, these surveys are designed to reveal new geological information at regional scale. The Paterson airborne electromagnetic data were acquired at line spacings of between one and six kilometres, a total of 28 200 line km and covers an area of 47 600 km<sup>2</sup>. The outcomes of the Paterson AEM survey include mapping of subsurface geological features that are associated with unconformity-related, sandstone-hosted and palaeovalley-hosted uranium mineralisation. The data are also capable of interpretation for other commodities including metals and potable water as well as for landscape evolution studies. The improved understanding of the regional geology resulting from the Paterson survey results will be of considerable benefit to mining and mineral exploration companies. This Data Package is for Archive to the internal area of the CDS and contains all data, grids, images, mxd, shape files, documentation, licenses, agreements, interpretations and scripts used to create the Paterson deliverables. At the projects completion (2012) all directories are required to be moved off the NAS. The reason to keep all the files is that more work is to be done on this data in the 2012-2015 period and these files may be needed in this future work.

  • Data to support the Wallaby Plateau GA Record 13-7113. This includes: 1. Magnetic modelling input data and model results 2. Gravity modelling input data and model results 3. Dredge sample rock properties associated with the Wallaby Plateau

  • A three-dimensional (3D) map of the Cooper Basin region has been produced from 3D inversions of Bouguer gravity data using geological data to constrain the inversions. The 3D map has been used to predict temperatures and their uncertainty throughout the volume of the map. This will allow regions of elevated predicted temperature at 4-5 km to be identified, which may provide targets for future geothermal exploration in the Cooper Basin region. The 3D map delineates regions of low density within the basement of the Cooper and Eromanga basins that are inferred to be granitic bodies, which may act as heat sources. It also delineates the stratigraphy of the sedimentary basins which act as thermal insulation. This release is the second version of the 3D map of the Cooper Basin region. It builds on Version 1 of the Cooper Basin Region Geological map, released in 2009.

  • Airborne Electromagnetic data are being acquired by Geoscience Australia in areas considered to have potential for uranium or thorium mineralisation under the Australian Government's Onshore Energy Security Program (OESP). The surveys have been managed and interpreted by Geoscience Australia's Airborne Electromagnetic Acquisition and Interpretation project. Three survey areas were recognised in the Pine Creek AEM survey area: Woolner Granite (TEMPEST), Rum Jungle (TEMPEST) and Kombolgie (VTEM). Industry paid for infill - all of this data has now been released to the public domain and is available at the GA website. In contrast to industry style deposit scale investigations, these surveys are designed to reveal new geological information at regional scale. The Pine Creek airborne electromagnetic data were acquired at line spacing's of between one and five kilometres, a total of 29 000 line km and covers an area of 73 000 km squared. The outcomes of the Pine Creek AEM survey include mapping of subsurface geological features that are associated with unconformity-related, sandstone-hosted and palaeovalley-hosted uranium mineralisation. The data are also capable of interpretation for other commodities including metals and potable water as well as for landscape evolution studies. The improved understanding of the regional geology resulting from the Pine Creek survey results will be of considerable benefit to mining and mineral exploration companies.

  • The Collaborative Australian Protected Areas Database (CAPAD) 2014 provides both spatial and text information about government, Indigenous and privately protected areas for continental Australia. State and Territory conservation agencies supplied data current to 30 June 2014. The terrestrial component of the database has been previously released in 1997, 2000, 2002, 2004, 2006, 2008 2010 and 2012. This version, provides both spatial and text information about off-shore protected areas in both state and Commonwealth waters. State and Territory conservation agencies supplied data current for 30 June 2014. This is the seventh version of the CAPAD- Marine database, with previous versions published in 1997, 2002, 2004, 2008 2010 and 2012. CAPAD provides a snapshot of protected areas that meet the IUCN definition of a protected area: "A protected area is an area of land and/or sea especially dedicated to the protection and maintenance of biological diversity, and of natural and associated cultural resources, and managed through legal or other effective means" (IUCN 1994). The Australian Government Department of the Environment (DOE) publishes a summary of the CAPAD data biennially on its website at http://www.environment.gov.au/capad This version of CAPAD 2014 (marine and terrestial) is a public / downloadable dataset available for use through the CC-BY licencing model.

  • This 2 CD package contains the January 2002 edition of the Australian bathymetry and topography grid at 0.01 deg (~1 km) cell size. Both binary and ASCII formats are included, suitable for most common image processing and GIS applications. The topography is from Geoscience Australia's (formerly AUSLIG's) 2nd edition digital elevation model for Australia. It is included for continuity with bathymetric features. The bathymetry is from digitised charts obtained from the Australian Hydrographic Service, swath bathymetry surveys, and other ship-track data of various vintages and navigational accuracy sourced from Geoscience Australia databases. The ship-track data have been levelled to reduce the artefacts due to misties at intersections.

  • The processing, interpretation and mapping of slicks offshore of the South West Margins using ten ERS satellite radar scenes and four Radarsat scenes has been completed successfully. All slick interpretations have been attributed with a hydrocarbon likelihood Level ranging from Level 2 to Level 4 with Level 2 being the most likely. Given the absence of actual field data, no Level 1 slicks have been mapped (see Glossary of Slick and Other Interpretations, p3 below). For all the fourteen scenes interpreted and mapped, there is only one Level 2 slick. This significant slick is located on the western edge of scene ERS 2 WO 01907-01 Orbit 5883. No locations have been provided of the sources of mapped slicks. Although an approximate point source would normally be provided for Level 2 slicks, the only Level 2 slick mapped (as above) is not complete as it is on the edge of the image (and presumably would continue on to an adjacent image acquired at the same time if it were available) and given the depth to sea floor of between 2,500m to 3,000m, it is not possible to provide a point source. Likewise, while an approximate point source would normally be provided for Level 3 slicks, given the depth to sea floor in the locations of the two Level 3 slicks mapped (same scene as for the Level 2 slick) of between 2,500m to 5,500m, it is not possible to provide a point sources. As per normal, Level 4 slicks are not provided with a source point. Many of the Level 4 slicks are located along the coastline in or near to the surf break zone (some possibly adjacent to rocky outcrops) and as such are regarded as false slicks as they most likely relate to differences in sea surface conditions and not to the formation of hydrocarbons.
