A strontium isoscape of southwestern Australia and progress toward a...
Strontium isotopes (87Sr/86Sr) are widely used tracers in the geosciences. Here we exploit an opportunity to determine 87Sr/86Sr ratios on archived fluvial sediment samples from... -
Ambient noise tomography of Australia: application to AusArray deployment
Over the past two decades, the use of seismic ambient noise has shown great potential in imaging the structure of the crust and lithospheric mantle. However, few datasets have... -
Evaluating the performance of soil flux surveys and inversion methods for...
Understanding the near surface migration patterns and rates of efflux of CO2 is important for developing effective monitoring and verification programs for the geological... -
Australia's Maritime Jurisdiction: Search and Rescue Region
Map showing the whole extent of Australia's Maritime Jurisdiction. Produced for the Australian Customs Service (Border Protection) with simplified legend showing 2012 confirmed... -
Modelled differences of coral life-history traits influence the refugium...
Remote populations can influence connectivity and may serve as refugia from climate change. We investigated two reef-building corals (Pseudodiploria strigosa and Orbicella... -
The tectonostratigraphic history of the Proterozoic Northern Lawn Hill...
The Northern Lawn Hill Platform (NLHP) comprises an area of approximately 16,000 km2 in north-central Australia. Thick packages of Proterozoic strata outcrop in the region,... -
A regolith lead isoscape of Australia
We present the first national-scale lead (Pb) isotope maps of Australia based on surface regolith for five isotope ratios, 206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb, 207Pb/206Pb,... -
Government geoscience accelerating resource discovery and development
Collaborative government geoscience programs deliver data and information on Australia’s natural resources. Precompetitive geoscience is publicly available data and information... -
The Potential for Geological Sequestration of CO2 in Australia: Preliminary...
Many industries and researchers have been examining ways of substantially reducing greenhouse gas emissions. No single method is likely to be a panacea, although some options do... -
Light Stable Isotopes in Volcanic-Hosted Massive Sulfide Ore Systems
Volcanic-hosted massive sulfide (VHMS) deposits, the ancient analogues of “black smoker” deposits that currently form on the seafloor, are the products of complex mineral... -
The Hera orebody: a complex distal (Au-Zn-Pb-Ag-Cu) skarn in the Cobar Basin...
The Hera Au–Pb–Zn–Ag deposit in the southeastern Cobar Basin of central New South Wales preserves calc-silicate veins/skarn and remnant carbonate/sandstone-hosted skarn within a... -
Bremer and Vlaming Release Areas: New Exploration Opportunities from...
In May 2003, the Australian Government announced A$61 million in funding for Geoscience Australia’s New Petroleum Program. This four-year program aims to develop new exploration... -
An Updated Fourier Spectral Attenuation Model for Southwestern Western Australia
Earthquake ground-motion data recorded on the South-West Australia (seismic) Network (SWAN) are augmented to existing ground-motion datasets for the southwest Western Australian... -
Surficial and deep earth material prediction from geochemical compositions -...
Prediction of true classes of surficial and deep earth materials using multivariate geospatial data is a common challenge for geoscience modellers. Most geological processes... -
Bayesian inversion using nested trans-dimensional Gaussian processes
To understand earth processes, geoscientists infer subsurface earth properties such as electromagnetic resistivity or seismic velocity from surface observations of... -
Historical earthquakes of the eastern Sunda Arc: Source mechanisms and...
Historical reports of earthquake effects from the period 1681 to 1877 in Java, Bali and Nusa Tenggara are used to independently test ground motion predictions in Indonesia’s... -
An integrated approach to assessing marine seismic impacts: Lessons learnt...
Marine seismic surveys are a fundamental tool for geological research, including the exploration of offshore oil and gas resources, but the sound generated during these surveys... -
Earthquake Risk and Mitigation Assessment in the Yilgarn, WA
We performed an earthquake risk assessment of seven smaller communities across the Yilgarn of Western Australia (WA): Northam, Merredin, Cunderdin, Kellerberrin, Wundowie,... -
Trusted environmental and geological information. Stratigraphic frameworks...
The Australian Government's Trusted Environmental and Geological Information (TEGI) program is a collaboration between Geoscience Australia and the CSIRO that aims to provide... -
Projection-Independent Earth-Solar-Sensor Geometry for Surface Reflectance Correction
We present a novel method for calculating Earth-solar-sensor geometry for remote sensing data in an arbitrary map projection. The geometry algorithm uses a recursive bisection...
