Australian National Seismograph Network (ANSN) These data are the time series seismograph, hydroacoustic and infrasound data recorded from ANSN Australian National Seismograph Network (ANSN) These data are the time series seismograph, hydroacoustic and infrasound data recorded from ANSN observatories in Australia, islands in the Pacific, Southern and Indian Ocean's and the Australian Antarctic Territory. ANSN observatories include facilities operated by Geoscience Australia in collaboration with other international agencies. These data are acquired for the purpose of the detection and location of earthquakes and tsunamigenic events within the Australian continent and its surrounds. The dataset is also used to meet a subset of Australia's obligations to the Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO) to fulfil Australia's commitment to nuclear explosion monitoring. The seismic waveform data records seismic events to allow for the detection, location estimation (position and depth) and magnitude of earthquakes of magnitude of 3.0 or greater anywhere in Australia.

The TCRM Stochastic Event Catalogue contains artificially generated tropical cyclone tracks and wind fields representing 10000 years of tropical cyclone activity. The catalogue is stored by year, with a track file and wind field file. The wind field file contains the maximum wind speed from all events occuring in the corresponding track file (i.e. it represents annual maximum wind speeds).

Collection containing geological descriptions of and measurements from field sites and samples from geological (including regolith) surveys. Provides underpinning location and descriptive information for Laboratory Analyses.

The offshore seismic data consists of field, processed, and seismic navigation data. Reports of the acquisition, processing and interpretation reports plus reprocessed seismic data and reports are also held. The collection is derived from the submission of seismic data under the Offshore Petroleum and Greenhouse Gas Storage Act and previous legislation. The Petroleum (Submerged Lands), the Offshore Petroleum, and the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGSA) requires petroleum data to be submitted to the State Designated Authority (DA). The Act(s) also require the DAs to make copies of the data available to the Commonwealth Minister through the Joint Authority.

Geoscience Australia (GA) has created a unique collection of 3D structural and geological models and model inputs for Australia and its near shore regions. Currently the collection contains a variety of 3D volumetric models and surfaces that were produced for specific projects at regional to continental scale. The approximately 40 regional scale models in the collection cover roughly 1/3 of the Australian continent. The models capture 3D stratigraphy and architecture, including the depth to bedrock and the locations of different major rock units, faults and geological structures. The geologic models represent the integration of geophysical surveys, seismic surveys, borehole data, field geology, and geochemical data, the majority of which will now be available through this and other RDSI collections. In their current form, the 3D models provide a valuable input to simulations of geological processes. However, the plan over time is to use the HPC capability at NCI and the large storage volumes available to dynamically integrate the various models and geological, geochemical and geophysical derivative products to then create a unified 3D model for the entire continent. Separately and then cumulatively, these models will provide an important new basis for describing and understanding Australia's geologic evolution and resource wealth. Currently there are no international open standards for the development and storage of 3D geological models, which is why they are difficult to integrate or stitch into nationally integrated data sets. The lack of consistency of the models means that each has to be transformed into formats compatible with existing HP modelling and simulation software. It is hoped that through exposing these 3D geological models into a HP collaborative environment that this will foster and accelerate the development of international standards and tools necessary for the assimilation of 3D geological models into a variety of HP programs. <b> Note: This record has been superseded by eCat 144629:</b> - <a href="https://pid.geoscience.gov.au/dataset/ga/144629">https://pid.geoscience.gov.au/dataset/ga/144629</a>

Magnetotellurics (MT) is a passive geophysical method which uses natural time variations of the Earth's magnetic and electric fields to measure the electrical resistivity of the sub-surface. Electrical resistivity is a bulk property of a volume of Earth material and is associated with factors such as rock composition, porosity and permeability as well as temperature and pressure. The Magnetotelurics (MT) Data Collection includes datasets from The Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) and regional-scale MT surveys across the Australian continent. These data were collected by Geoscience Australia in collaboration with the State and Territory Geological Surveys and other partners. <b>Value: </b>Magnetotelluric data to expand the geoscientific understanding of the earth's lithospheric structure and provide new insights into Australia's onshore energy and mineral potential. <b>Scope: </b>AusLAMP is being conducted over multiple years to create a national MT dataset and map lithospheric structure of the Australian continent. MT data have also been acquired for mapping crustal structure and resource potential at regional scale. These data provide valuable information for multi-disciplinary interpretations.

The National Spectral Database (NSD) houses data from Australian remote sensing scientists. The database includes spectra covering targets as diverse as mineralogy, soils, plants, water bodies and various land surfaces. Currently the database holds spectral information from multiple locations across the country and as the collection grows in spatial / temporal coverage, the NSD will service continental scale validation requirements of the Earth observation community for satellite-based measurements of surface reflectance. <b>Value:</b> Curated spectral data provides a wealth of knowledge to remote sensing scientists. For other parties interested in calibration and validation (Cal/Val) of surface reflectance products, the Geoscience Australia (GA) Cal/Val dataset provides a useful resource of ground-truth data to compare to reflectance captured by Landsat 8 and Sentinel 2 satellites. The Aquatic Library is a robust collection of Australian datasets from 1994 to present time, primarily of end-member and substratum measurements. The University of Wollongong collection represents immense value in end-member studies, both terrestrial and aquatic. <b>Scope:</b> The NSD covers Australian data including historical datasets as old as 1994. Physical study sites encompass locations around Australia, with spectra captured in every state. <b>Data types:</b> - Spectral data: raw digital numbers (DN), radiance and reflectance.  - From spectral bands VIS-NIR, SWIR1 & SWIR2: wavelengths 350nm - 2500nm collected with instruments in the field or lab setting.

Comprises a national satellite imagery mosaic and derived information products produced by a collaboration of CSIRO, Geoscience Australia (GA) and State and Territory Surveys, and several additional national and international collaborators. Mineral products were derived using a validated mosaic of Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data. <b>Value: </b>The data are used to understand distributions of and changes in surface materials and assessment of environmental, agricultural and resource potential. <b>Scope: </b>This dataset covers the continent with the intent to provide the best quality mosaic from 10+ year archive of scenes across Australia (i.e., lowest cloud/vegetation cover, high sun angle etc)

Wind multipliers are factors that transform wind speeds over open, flat terrain (regional wind speeds) to local wind speeds that consider the effects of direction, terrain (surface roughness), shielding (buildings and structures) and topography (hills and ridges). During the assessment of local wind hazards (spatial significance in the order 10's of metres), wind multipliers allow for regional wind speeds (order 10 to 100's of kilometres) to be factored to provide local wind speeds. <b>Value: </b>The wind multiplier data is used in modelling the impacts (i.e. physical damage) of wind-related events such as tropical cyclones (an input for Tropical Cyclone Risk assessment), thunderstorms and other windstorms. <b>Scope: </b>Includes terrain, shielding and topographic multipliers for national coverage. Each multiplier further contains 8 directions.
