Benfield and Geoscience Australia intend to collaborate to improve their respective understanding of risks from natural hazards in Australia. The aim of this project is to exchange ideas, data and models in order to support the respective groups risk modeling expertise.

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 Note: This record has been superseded by eCat 144629: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>

A collection of NetCDF files containing ground gravity point data that is organised by survey. The files are derived from the Australian National Gravity Database (ANGD), and formatted in such a way as to provide highly efficient, analysis ready data. The data covers the onshore Australian continent, and dates from 1947 until June 2019. Surveys acquired after June 2019 are not included in this collection, but are available via the Data & Publication search or the Geophysical Archiving and Data Delivery System (GADDS).

Parametric dataset of earthquakes in the Australian region, with magnitudes greater than 2.5. Includes records of instrumentally recorded earthquakes and explosions, and earthquake parameters inferred from historic documents. Threshold magnitude of completeness varies spatially and temporally. <b>Value: </b>This data has historic value, and is used in assessment of earthquake hazard, risk and potential impacts from future events. <b>Scope: </b>A catalogue of known historical earthquakes in Australia and adjacent regions.

Collection of field notebooks recording mainly geological observations made by staff of Geoscience Australia (GA) and its predecessors, Bureau of Mineral Resources (BMR) and Australian Geological Survey Organisation (AGSO), while conducting fieldwork between 1930 and 2010. The notebooks are currently being digitised. <b>Value: </b>Historic and scientific significance. Many sites visited are remote and have rarely been revisited. Some notebooks also record observations on fauna and flora. <b>Scope: </b>Geographical scope is largely Australia, pre- and post-Independence Papua New Guinea (PNG), and the Australian Antarctic Territory, but other countries and territories are represented.

Collection of mineral, gem, meteorite, fossil (including the Commonwealth Palaeontological Collection) and petrographic thin section specimens dating back to the early 1900s. The collection is of scientific, historic, aesthetic, and social significance. Geoscience Australia is responsible for the management and preservation of the collection, as well as facilitating access to the collection for research, and geoscience education and outreach. Over 700 specimens from the collection are displayed in our public gallery . The collection contains: • 15,000 gem, mineral and meteorite specimens from localities in Australia and across the globe. • 45,000 published palaeontological specimens contained in the Commonwealth Palaeontological Collection (CPC) mainly from Australia. • 1,000,000 unpublished fossils in a ‘Bulk Fossil’ collection. • 250,000 petrographic thin section slides. • 200 historical geoscience instruments including: cartography, geophysical, and laboratory equipment." <b>Value: </b>Specimens in the collection are derived from Geoscience Australia (GA) surveys, submissions by researchers, donations, purchases and bequests. A number of mineral specimens are held on behalf of the National Museum of Australia. <b>Scope: </b>This is a national collection that began in the early 1900s with early Commonwealth surveys collecting material across the country and British territories. The mineral specimens are mainly from across Australia, with a strong representation from major mineral deposits such as Broken Hill, and almost 40% from the rest of the world. The majority of fossils are from Australia, with a small proportion from lands historically or currently under Australian control, such as Papua New Guinea and the Australian Antarctic Territory.

Although the Bureau of Mineral Resources, Geology and Geophysics was created in 1946, it did not compile an annual report until 1971. The series continued under this title up to 1976, all but the last providing summaries of annual activities by broad sections (functions and organisation, field operations, laboratory studies, observatories, and so on). The 1976 Annual Report adopted a shorter format, a general outline of the role, objectives and programs of the Bureau being followed by a selection of short articles on the "more innovative and conclusive activities" of that year. This new format was retained in 1977 when a title change was made and the annual summaries became known as BMR Yearbooks.

Data in the GEOCHEM database comprises inorganic geochemical analytical data and associated metadata. Geochemical data comprises concentration data (value, error, unit of measure) measured on a range of analytical instruments, for a range of elements of the periodic table. Associated metadata includes information on analytical techniques, analytical methodology, laboratory, analysts, date of analysis, detection limits, accuracy, and precision. The GEOCHEM database also records results for reference standards. Data is specifically for rocks, soils and other unconsolidated geological material and does not include oils, gases or water analyses. Geochemical data may be total rock (i.e., whole rock analysed) or for a variety of fractions of the total rock, e.g., various non-total acid digests, mineral separates, differing size fractions. It also includes quantitative to semi-quantitative data from field measurements, such as portable x-ray fluorescence (XRF). It does not include geochemical data for individual minerals. <b>Value: </b>Geochemical data underpins much geoscientific study, and is used directly to classify, characterise and understand geological material and its formation. It has direct relevance to understanding the formation of the earth, the continents, and the processes that create and shape the surface we live on. For example, this information is used within: both discovering and the understanding of mineral deposits we depend on; the nature, health and sustainability of the soils we live and farm on; as well as providing input into a range of potential geohazards. <b>Scope: </b>The collection includes data from over 60 years of Geoscience Australia (GA) and state/territory partner regional geological projects within Australia, as well as continental-scale and regional geochemical surveys like National Geochemical Survey of Australia (NGSA) and Northern Australia Geochemical Survey (NAGS) (Exploring for the Future- EFTF). It also includes data from other countries that GA has worked with, e.g., Papua New Guinea, Antarctica, Solomon Islands and New Zealand.
