This dataset is a spatial representation of the Geoscience Australia Earthquake Database. The dataset contains recorded magnitudes for earthquakes on and near Australia. Local events of magnitude 4 and above and regional events of magnitude 6 and above are displayed.

The world's first satellite-derived mineral maps of a continent, namely Australia, are now publicly available as digital, web-accessible products. The value of this spatially comprehensive mineral information is readily being captured by explorers at terrane to prospect scales. However, potentially even greater benefits can ensue for environmental applications, especially for the Earth's extensive drylands which generate nearly 50% of the world's agricultural production but are most at risk to climate change and poor land management. Here we show how these satellite mineral maps can be used to: characterise soil types; define the extent of deserts; fingerprint sources of dust; measure the REDOX of iron minerals as a potential marine input; and monitor the process of desertification. We propose a 'Mineral Desertification Index' that can be applied to all Earth's drylands where the agriculturally productive clay mineral component is being lost by erosion. Mineral information is fundamental to understanding geology and is important for resource applications1. Minerals are also a fundamental component of soils2 as well as dust eroded from the land surface, which can potentially impact on human health3, the marine environment4 and climate5. Importantly, minerals are well exposed in the world's 'drylands', which account for nearly 50% of Earth's land area6. Here, vegetation cover is sparse to non-existent as a result of low rainfall (P) and high evaporation (E) rates (P/E<0.65). However, drylands support 50% of the world's livestock production and almost half of all cultivated systems6. In Australia, drylands cover 85% of the continent and account for 50% of its beef, 80% of its sheep and 93% of its grain production7. Like other parts of the world, Australia is facing serious desertification of its drylands6. Wind, overgrazing and overstocking are major factors in the desertification process8. That is, the agriculturally productive clay-size fraction of soils (often includes organic carbon) is lost largely through wind erosion, which is acerbated by the loss of any vegetative groundcover (typically dry plant materials). Once clay (and carbon) loss begins, then the related break down of the soil structure and loss of its water holding capacity increases the rate of the degeneration process with the final end products being either exposed rock or quartz sands that often concentrate in deserts.

AMSIS is a web based interactive mapping and decision support system that improves access to integrated government and non-government information in the Australian Marine Jurisdiction. AMSIS contains over 80 layers of information including maritime boundaries, bathymetry, physical and environmental information, legal interests, fisheries and shipping that has been sourced from Geoscience Australia, other Australian government agencies and some industry sources. AMSIS also contains the offshore mineral locations data that was used to create the Offshore Minerals Map. AMSIS has been developed using standards to support interoperability enabling integration with the National Oceans Portal and other on-line initiatives. Geoscience Australia is working with other agencies and organisations to add additional information. Information in this application should not be relied upon as the sole source of information for commercial and operational decisions. AMSIS should not be used for navigational purposes.

This is part of a series of 49 maps covering the whole of Australia and forms part of the International Map of the World map series. At this scale 1 centimetre on the map represents 10 kilometres on the ground. Each map covers an area of six degrees of longitude and four degrees of latitude. The maps show roads, railways, hydrography, larger nature conservation reserves, outback homesteads. Seabed and land relief is shown by layer tints, spot heights and contours in metres. Contour interval is 500 metres, with an additional contour at 200 metres. Product Specifications Coverage: Whole of Australia covered with 49 maps. National coverage first completed in 1975. Currency: Ranges from 1971 to 1983. Average 1976. Coordinates: Geographical. Datum: AGD66 (GDA94 compliant at this scale); AHD. Projection: Lambert Conformal Conic. Medium: Paper map, flat and folded. Status: These maps are no longer maintained. It is planned to produce a new series of maps from the converted 42 World Aeronautical Charts (WAC) series of maps produced in 2006. These maps are only available as a print on demand product. This map can be purchased in either flat or folded format.

The Dynamic Land Cover Dataset of Australia is the first nationally consistent and thematically comprehensive land cover reference for Australia. It is the result of a collaboration between Geoscience Australia and the Australian Bureau of Agriculture and Resource Economics and Sciences, and provides a base-line for identifying and reporting on change and trends in vegetation cover and extent. The thematic map product shows the land cover of Australia for the period of March 2000 to March 2008 in 34 Internation Standards Organisation (ISO) land cover classes.

This gravity anomaly image has been derived from observations stored in the Australian National Gravity Database (ANGD) as at February 2016 as well as data from the 2013 New South Wales Riverina gravity survey. Out of the approximately 1.8 million gravity observations 1,371,998 gravity stations in the ANGD together with 19,558 stations from the Riverina survey were used to generate this image. The image shows complete Bouguer anomalies over onshore continental Australia. The data used in this image has been acquired by the Commonwealth, State and Territory Governments, the mining and exploration industry, universities and research organisations from the 1940's to the present day. Terrain corrections to gravity were calculated using both offshore bathymetry and onshore topography data. These terrain corrections were applied to the spherical cap Bouguer anomalies used in the Bouguer Gravity Anomaly Grid of Onshore Australia 2016 to produce the complete Bouguer anomalies shown in this image. The Complete Bouguer Gravity Anomaly Grid of Onshore Australia 2016 has been image enhanced and displayed as a hue-saturation-intensity (HSI) image with sun shading from the northeast to create this product.
