This web service delivers metadata for onshore active and passive seismic surveys conducted across the Australian continent by Geoscience Australia and its collaborative partners. For active seismic this metadata includes survey header data, line location and positional information, and the energy source type and parameters used to acquire the seismic line data. For passive seismic this metadata includes information about station name and location, start and end dates, operators and instruments. The metadata are maintained in Geoscience Australia's onshore active seismic and passive seismic database, which is being added to as new surveys are undertaken. Links to datasets, reports and other publications for the seismic surveys are provided in the metadata.

The Source Rock and Fluids Atlas delivery and publication services provide up-to-date information on petroleum (organic) geochemical and geological data from Geoscience Australia's Organic Geochemistry Database (ORGCHEM). The sample data provides the spatial distribution of petroleum source rocks and their derived fluids (natural gas and crude oil) from boreholes and field sites in onshore and offshore Australian basins. The services provide characterisation of source rocks through the visualisation of Pyrolysis, Organic Petrology (Maceral Groups, Maceral Reflectance) and Organoclast Maturity data. The services also provide molecular and isotopic characterisation of source rocks and petroleum through the visualisation of Bulk, Whole Oil GC, Gas, Compound-Specific Isotopic Analyses (CSIA) and Gas Chromatography-Mass Spectrometry (GCMS) data tables. Interpretation of these data enables the characterisation of petroleum source rocks and identification of their derived petroleum fluids that comprise two key elements of petroleum systems analysis. The composition of petroleum determines whether or not it can be an economic commodity and if other processes (e.g. CO2 removal and sequestration; cryogenic liquefaction of LNG) are required for development.

The Cenozoic alkaline and related igneous rocks of Australia web map service depicts the spatial representation of the alkaline and related rocks of Cenozoic age.

<b>IMPORTANT NOTICE:</b> This web service has been deprecated. The Australian Onshore and Offshore Boreholes OGC service at https://services.ga.gov.au/gis/boreholes/ows should now be used for accessing Geoscience Australia borehole data. This is an Open Geospatial Consortium (OGC) web service providing access to a subset of Australian geoscience samples data held by Geoscience Australia. The subset currently relates specifically to Australian Boreholes.

The Proterozoic alkaline and related igneous rocks of Australia web map service depicts the spatial representation of the alkaline and related rocks of Proterozoic age.

This web service delivers the geographical extents and descriptive metadata of geophysical datasets from all surveys conducted or managed by Geoscience Australia and its predecessor agencies, as well as from State and Territory geological survey agencies. Datasets include gravity, magnetic, radiometric, and electromagnetic data, and elevation data collected during geophysical surveys.

OPGGSA 2006 - Petroleum Blocks. This service displays the most recent realisation of the Petroleum Blocks as defined under Section 33 (3) of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGSA 2006) as realised in GDA94. Block data extends beyond the area of operation of the OPGGSA and includes areas of coastal waters and land within the constitutional limits of the States and Territories.

This service contains features as defined under the Offshore Petroleum and Greeenhouse Gas Storage Act 2006. The Petroleum blocks defined under the Act, are delivered separately in the 'Australia - OPGGSA 2006 - Petroleum Blocks' service.

The Emergency Management service contains known spatial locations; in point format, of all known policing facilities, ambulance stations, metropolitan fire facilities, rural fire facilities and SES facilities and Other Emergency Management facilities within Australia.

This service provides header and observation data for gravity stations located throughout continental Australia and Remote Offshore Territories. Data sources include the Australian National Gravity Database (ANGD) and the Australian Fundamental Gravity Network (AFGN) maintained by Geoscience Australia (GA). Data has been obtained by Surveyors, Commonwealth and state/territory Governments, private companies, and educational institutions. Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
