The national Marine Sediments collection is a scientific resource that includes information for samples collected within the Australian marine jurisdiction, including location, water depth, sampling method and sample descriptions. Data are provided from quantitative analyses of the samples, such as grain size, mud, sand, gravel and carbonate concentrations. Additional analyses on some samples include mineralogy, age determinations, geochemical properties, and physical attributes for down-core samples including bulk density, p-wave velocity, porosity and magnetic susceptibility. Images and graphics are presented, where available. MARS currently holds >40,000 sample and sub-sample records, and approximately 200,000 records describing the characteristics of these samples. New data are being added as they become available. <b>Value: </b>Seabed sediment data is used to characterise the surface geology of the sea floor, important in resource exploration, marine zone management and understanding the physical environment. <b>Scope: </b>Samples were collected from Australia's marine jurisdiction, including the Australian Antarctic Territory. >40,000 sample and sub-sample records, and approximately 200,000 records describing the characteristics of these samples.

A collection of mining and explotation tenements supplied by the individual state and territory bodies. Loaded monthly to an Oracle database from shapefiles given to Geoscience Australia.

Climate simulations used in the FireDST project. They include Case Study I, II and III, all these simulations were generated by BoM for this project.

The MARine Sediment (MARS) database contains detailed information on seabed sediment characteristics for samples collected from Australia's marine jurisdiction, including the Australian Antarctic Territory. It is an important scientific resource that includes sediment properties from seabed and sub-seabed samples spanning coastal, continental shelf and deep sea locations. Analytical properties include grain size, carbonate content, mineralogy, geochemical properties and age determinations. MARS currently holds approximately 100,000 sample records and new data are being added as they become available. Please contact us at ausseabed@ga.gov.au if you wish to contribute marine sediment data to the MARS database.

The Geoscience Australia Rock Properties database stores the results measurements of scalar and vector petrophysical properties of rock and regolith specimens. Many are sourced from Geoscience Australia's mapping and research programs, but some are are compiled from published literature, university studies, the resources industry and State/Territory geological surveys. Measured properties include mass density, magnetic susceptibility, magnetic remanence, gamma, electrical conductivity and sonic velocity. The database also records analytical process information such as methods and instrument details wherever possible.
