Clarence Richmond ppm uranium grid geodeticg

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This radiometric uranium grid has a cell size of 0.00042 degrees (approximately 43m) and shows uranium element concentration of the Clarence-Richmond Coastal Area, NSW, 1996 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1996 by the NSW Government, and consisted of 48370 line-kilometres of data at a line spacing between 200m and 1600m, and 80m terrain clearance.

National Seismic Risk Assessment for Residential Buildings in Australia using NSHA23

The overall earthquake bedrock hazard across Australia is low compared to the hazard of countries located at tectonic plate boundaries. This hazard is, however, variable and some regions of the country have hazard that would be considered moderate. Coupling this variability with the variability of overlying regolith and that of the building stock, the risk associated with earthquake damage has greater spatial variability that is not well understood. Reported in this paper is a consistent national-scale seismic risk assessment for residential houses in Australia that has used the latest seismic hazard model developed through the National Seismic Hazard Assessment 2023 (NSHA23). For the exposure information used, building attributes were extracted from the National Exposure Information System (NEXIS) developed and maintained by Geoscience Australia (GA). All the residential buildings were grouped into four primary types for which vulnerability was assessed using empirical damage data from past Australian earthquakes. In turn, the vulnerability models were nuanced to consider the high lateral load resistance of houses in cyclonic regions of Australia. The average annualised loss (AAL) ratio was computed using the OpenQuake-engine implemented at the National Computational Infrastructure (NCI). The computed AAL ratio was later aggregated to Australian Bureau of Statistics (ABS) Statical Area One (SA1). The AAL ratio of the whole Australia was estimated to be 0.00646 (%). Northern Territory was the highest state and territory by AAL ratio, followed by Western Australia. In this paper, details of the inputs and outcomes of the assessment are presented. These are discussed in terms of the changes in hazard understanding in transitioning from NSHA18 to NSHA23 and in terms of the change of vulnerability models across the country.

This GSV Alexandra VIMP Vic pot tho ura totg 4band radiometric grid geodetic has a cell size of 0.0005 degrees (approximately 50m). The data used to produce this grid was acquired in 2000 by the VIC Government, and consisted of 23055 line-kilometres of data at 200m line spacing and 80m terrain clearance. The grid was produced by applying the colours red to the Potassium ground concentration, green to the Thorium concentration and blue to the Uranium concentration. The colours were clipped to a 99% linear scale. These colours were transparent over a shaded Total Count. This clipping will necessarily introduce some artefacts into the ratio grids in areas of very low radioelement concentrations. The 3-band image was superposed on the sun shaded TC grid of the same survey to produce the final image.

Geomorphic and cosmogenic nuclide constraints on escarpment evolution in an intraplate setting, Darling Escarpment, Western Australia

The ~900 km long Darling Scarp in Western Australia is one of the most prominent linear topographic features on Earth. Despite the presence of over-steepened reaches in all westerly flowing streams crossing the scarp, and significant seismic activity within 100 km of the scarp, there is no historical seismicity and no reported evidence for Quaternary tectonic displacements on the underlying Darling Fault. Consequently, it is unclear whether the scarp is a rapidly evolving landform responding to recent tectonic and/or climatic forcing or a more slowly evolving landform. In order to quantify late Quaternary rates of erosion and scarp relief processes, we obtained measurements of the cosmic-ray produced nuclide beryllium-10 (10Be) from outcropping bedrock surfaces along the scarp summit and face, in valley floors, and at stream knickpoints. Erosion rates of bedrock outcrops along the scarp summit surface range from 0·5 to 4·0 m Myr-1. These are in the same range as erosion rates of 2·1 to 3·6 m Myr-1 on the scarp face and similar to river incision rates of 2·6 to 11·0 m Myr-1 from valley floor bedrock straths, indicating that the Darling Scarp is a slowly eroding ‘steady state’ landform, without any significant contemporary relief production over the last several 100 kyr and possibly several million years. Knickpoint retreat rates determined from 10Be concentrations at the bases of two knickpoints on small streams incised into the scarp are 36 and 46 m Myr-1. If these erosion rates were sustained over longer timescales, then associated knickpoints may have initiated in the mid-Tertiary to early Neogene, consistent with early-mid Tertiary marginal uplift. Ongoing maintenance of stream disequilibrium longitudinal profiles is consistent with slow, regional base level lowering associated with recently proposed continental-scale tilting, as opposed to differential uplift along discrete faults. Cosmogenic 10Be analysis provides a useful tool for interpreting the palaeoseismic history of intraplate near-fault landforms over 105 to 106 years.

Investing in the development of an open source two-dimensional flood modelling capability

Floods are Australia's most expensive natural hazard with annual average damages estimated at $377 million. Modelling flood hazard and potential flood impact is therefore an important first step in reducing the cost of floods to the community. The availability of a rigorously tested free software modelling tool for flooding would assist in meeting this objective. ANUGA is a collaborative effort of Geoscience Australia and the Australian National University and has gained increasing interest as an open source two-dimensional flood model. The development of ANUGA for flood modelling purposes has been guided and furthered through close consultation with a number of local government and consulting engineers.
This paper highlights case studies where ANUGA has been used for both hydrological and hydraulic modelling. This paper also makes two broad recommendations. The first recommendation is for further model validation against historical flood events. Additional model comparison is also needed, particularly against other two-dimensional models. ANUGA should also be validated against a suite of hydraulic tests to provide confidence in ANUGA's ability to be used as a general purpose hydraulic model.
The second broad recommendation is that the ANUGA software is further developed to make it comparable with other two-dimensional flood models. Priorities for this development include the ability to model structures (culverts, pipes and bridges), the addition of a kinematic viscosity term and the inclusion of discharge as an inflow boundary condition. The ability to incorporate variable bed elevation in models, account for water storage in buildings and consider spatially and depth varying Manning's friction 'n' are also important. The development of a graphical (geographical information systems) user interface would make ANUGA more accessible.

AUSGeoid98 v.1.0 data files: Renmark (si54-10)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

Regional magnetic depth estimates for Eastern Resources Corridor (ERC), Officer Basin, Tasmania and Northeast Queensland

As part of the Australia's Resources Framework Project, in the Exploring for the Future Program, Geoscience Australia and CSIRO have undertaken a magnetic source depth study across four areas. These are: 1) the western part of Tasmania that is the southernmost extension of the Darling-Curnamona-Delamerian (DCD) project area; 2) northeastern Queensland; 3) the Officer Basin area of western South Australia and southeastern West Australia; and 4) the 'Eastern Resources Corridor' (ERC) covering eastern South Australia, southwest Queensland, western New South Wales and western Victoria. This study has produced 2005 magnetic estimates of depth to the top of magnetization. The solutions are derived by a consistent methodology (targeted magnetic inversion modelling, or TMIM; also known as ‘sweet-spot’ modelling). 

The magnetic depth estimates produced as part of this study provide depth constraints in data-poor areas. They help to construct a better understanding of the 3D geometry of the Australian continent, and aid cover thickness modelling activities. 

A supplementary interpretation data release is also available through Geoscience Australia's enterprise catalogue (ecat) at https://pid.geoscience.gov.au/dataset/ga/149499.

Geoscience Australia’s Exploring for the Future program provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources. By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia’s geology and resource potential. This leads to a strong economy, resilient society and sustainable environment for the benefit of all Australians. This includes supporting Australia’s transition to net zero emissions, strong, sustainable resources and agriculture sectors, and economic opportunities and social benefits for Australia’s regional and remote communities. The Exploring for the Future program, which commenced in 2016, is an eight year, $225m investment by the Australian Government. This work contributes to building a better understanding of the Australian continent, whilst giving the Australian public the tools they need to help them make informed decisions in their areas of interest.
