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 Flood Study Summary Services support discovery and retrieval of flood hazard information. The services return metadata and data for flood studies and flood inundation maps held in the 'Australian Flood Studies Database'. The same information is available through a user interface at http://www.ga.gov.au/flood-study-web/. A 'flood study' is a comprehensive technical investigation of flood behaviour. It defines the nature and extent flood hazard across the floodplain by providing information on the extent, level and velocity of floodwaters and on the distribution of flood flows. Flood studies are typically commissioned by government, and conducted by experts from specialist engineering firms or government agencies. Key outputs from flood studies include detailed reports, and maps showing inundation, depth, velocity and hazard for events of various likelihoods. The services are deliverables fom the National Flood Risk Information Project. The main aim of the project is to make flood risk information accessible from a central location. Geoscience Australia will facilitate this through the development of the National Flood Risk Information Portal. Over the four years the project will launch a new phase of the portal prior to the commencement of each annual disaster season. Each phase will increase the amount of flood risk information that is publicly accessible and increase stakeholder capability in the production and use of flood risk information. flood-study-search returns summary layers and links to rich metadata about flood maps and the studies that produced them. flood-study-map returns layers for individual flood inundation maps. Typically a single layer shows the flood inundation for a particular likelihood or historical event in a flood study area. To retrieve flood inundation maps from these services, we recommend: 1. querying flood-study-search to obtain flood inundation map URIs, then 2. using the flood inundation map URIs to retrieve maps separately from flood-study-map. The ownership of each flood study remains with the commissioning organisation and/or author as indicated with each study, and users of the database should refer to the reports themselves to determine any constraints in their usage.

This web map service provides the locations and status, as at 30 June 2020, of Australian operating mines, mines under development, mines on care and maintenance and resource deposits associated with critical minerals. Developing mines are deposits where the project has a positive feasibility study, development has commenced or all approvals have been received. Mines under care and maintenance and resource deposits are based on known resource estimations and may produce critical minerals in the future.

The Mineral Deposits and Mineral Resources OGC service provides data from Geoscience Australia’s OZMIN database in EarthResourceML 2.0 and ERML Lite 1.0 and associated contextual layers in simple WMS and WFS formats.

This web feature service delivers geochemical data for samples analysed both for inorganic and organic geochemistry. Analytical data are sourced from Geoscience Australia's Inorganic Geochemistry Database (OZCHEM) and Organic Geochemistry Database (ORGCHEM), respectively. The data are joined on a unique sample number. Inorganic geochemical data cover the majority of the periodic table, with metadata on analytical methods and detection limits. Organic geochemical data include results of pyrolysis, derivative calculated values, and, where available, isotopic composition of carbonates (D13C) and isotopic composition of rock nitrogen (D15N). Further, there are provisions for delivery of isotopic data for kerogen (H, C, N) and oxygen (O) for carbonates. Where available, sample descriptions include stratigraphic unit names and ages, and lithology. Location information includes coordinates of the sampled feature (eg, borehole), coordinates of the sample and sample depth. Interpretation of the combined inorganic and organic geochemistry for organic-rich shales will facilitate comprehensive characterisation of hydrocarbons source rocks and mineral commodities source and trap environments. All are achieved within the frameworks of petroleum and mineral systems analysis. The initial data delivered by this service include 1785 samples from 35 boreholes from 14 geological provinces, including recently released data for 442 samples from the South Nicholson National Drilling Initiative Carrara 1 stratigraphic drill hole (Butcher et al., 2021; Carson et al., 2021). Many sampled boreholes are located within the polygon of the Exploring for the Future Barkly-Isa-Georgetown project. This dataset will be updated periodically as more data become available.

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.

Offshore Minerals Act (OMA 1994) - Mineral Blocks. This service displays the most recent realisation of the Mineral Blocks as defined under the Offshore Minerals Act 1994 (OMA 1994) as realised in GDA94. Block data extends beyond the area of operation of the OMA and includes areas of coastal waters and land within the constitutional limits of the States and Territories.

Not current – This service has been deprecated in favor of the 2019 epoch, which includes amendments reflecting new boundary arrangements with Timor-Leste, which came into force on 30 August 2019. The Seas and Submerged Lands Act (SSLA) is the Australian legislation that provides the framework for Australia to declare the baselines, limits and zones provided under the first six parts of the United Nations Convention on the Law of the Sea. These baselines, limits and zones are declared by Proclamations provided for under this act. This service depicts official spatial representation of these proclamations. The service includes feature layers: Normal and Straight baselines limits and locations, Contiguous Zone and limit, Territorial Sea Zone and limit, Exclusive Economic Zone (EEZ) and limit, Continental Shelf limit and locations. NOTE: There are two versions of the Exclusive Economic Zone (EEZ) provided. One depicts the EEZ as proclaimed in the Seas and Submerged Lands Act 1973 - Proclamation under section 10B (26/07/1994). The second version includes amendments reflecting the provisions of the signed but not unratified Treaty between the Government of Australia and the Government of the Republic of Indonesia, establishing an Exclusive Economic Zone Boundary and Certain Seabed Boundaries (Perth, 14 march 1997) [1997] ATNIF 9 - (not yet in force). (Perth Treaty). The version reflecting Perth Treaty EEZ limits and area should be the standard depiction.

The service contains all maritime boundaries treaties signed by Australia (NOT ALL ARE IN FORCE). Where the original datum of the treaty is not specified as GDA94, all defined points have been transformed by Geoscience Australia's National Geospatial Reference Systems Section to GDA94.
