  • This service represents the National Digital Elevation Model (DEM) 1 Second Percentage Slope product, derived from the National DEM SRTM 1 Second. Slope measures the inclination of the land surface from the horizontal. Percent slope represents this inclination as the ratio of change in height to distance.

  • This web service provides access to the Waste Management Facilities dataset and presents the spatial locations of all the known waste management, recycling and reprocessing facilities within Australia, all complemented with feature attribution.

  • The Marine Survey Multibeam Bathymetry Web Map Service contains the highest-resolution multibeam bathymetry grids available for download on Geoscience Australia's website. These bathymetry grids were collected over numerous multibeam survey programs conducted in Australian mainland and Antarctic waters by both Geoscience Australia and our collaborators. Layers are grouped by survey or region and where available include both the Geoscience Australia and vessel survey identification numbers that contributed to the bathymetry grids. Bathymetry grids have been rendered over a rainbow colour-ramp with minimum and maximum depth values unique for each survey. These values are specified in each survey's layer description. The resolution of each bathymetry grid is also specified in each survey's layer description

  • Effective mineral, energy and groundwater resource management and exploration rely on accurate geological maps. While geological maps of the surface exist and increase in resolution, maps of the subsurface are sparse, and the underpinning geological and geophysical constraints are disordered or non-existent. The Estimates of Geological and Geophysical Surfaces (EGGS) database seeks to enable robust subsurface geological mapping by establishing an ordered collection of precious geological and geophysical interpretations of the subsurface. EGGS stores the depth to geological boundaries derived from boreholes as well as interpretations of depth to magnetic top assessments, airborne electromagnetics inversions and reflection seismic profiles. Since geological interpretation is iterative, links to geophysical datasets and processing streams used to image the subsurface are stored. These metadata allow interpretations to be readily associated with the datasets from which they are derived and re-examined. The geological basis for the interpretation is also recorded. Stratigraphic consistency is maintained by linking each interpretation to the Australian Stratigraphic Units Database. As part of the Exploring for the Future program, >170 000 points were entered into the EGGS database. These points underpin construction of cover thickness models and economic fairway assessments. <b>Citation:</b> Mathews, E.J., Czarnota, K., Meixner, A.J., Bonnardot, M.-A., Curtis, C., Wilford, J., Nicoll, M.G., Wong, S.C.T., Thorose, M. and Ley-Cooper, Y., 2020.

  • This dataset contains the limit and extent of Northern Australia as defined by the Northern Australia Infrastructure Facility Act 2016 (https://www.legislation.gov.au/Details/C2021C00228) and Northern Australia Infrastructure Facility Amendment (Extension and Other Measures) Act 2021 (https://www.aph.gov.au/Parliamentary_Business/Bills_Legislation/bd/bd2021a/21bd062).

  • This dataset contains waveforms and metadata from 5 temporary deployment seismometers and accelerometers stations following the Lake Muir 5.7 magnitude earthquake, WA, on the 16th September 2018. Data extends from 16th Nov 2018 to the 12th Feb 2019. Waveforms are in miniseed format with Metadata in xml format. Individual station datasets are labelled on station codes: LM01 through LM05.

  • A geological survey of HALLS CREEK, in the East Kimberley of Western Australia, was carried out from 1990 to 1994 as part of the Kimberley-Arunta National Geoscience Mapping Accord (NGMA) Project, undertaken jointly by the Australian Geological Survey Organisation (AGSO), the Geological Survey of Western Australia (GSWA) and the Northern Territory Geological Survey. The NGMA, endorsed by the Australian (now Australian and New Zealand) Minerals and Energy Council in August 1990, is a joint Commonwealth State Territory initiative to produce, using modem technology, a new generation of geological maps, data sets and other information on strategically important regions of Australia over a period of 20 years.

  • Examination of samples from· Arabella No.1, Candace No.1 and Kybra No.1, offshore Carnarvon Basin, Western Australia, for Triassic conodonts.

  • Total magnetic intensity data measures variations in the intensity of the Earth's magnetic filed caused by the contrasting content of rock-forming minerals in the Earth's crust. The data are collected on airborne geophysical surveys conducted by Commonwealth, State & NT Governments and the private sector.

  • Sixteen samples from the Mobil Petroleum exploration well Cody 1, Exmouth Gulf, Western Australia were examined for conodonts and other phosphatic microfossils. Conodonts were recovered in four samples and other faunal elements were found in an additional nine samples
