GSNSW Exploration NSW Area G SE Darling Basin total count grid geodetic

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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This GSNSW Exploration NSW Area G SE Darling Basin total count grid geodetic has a cell size of 0.00097 degrees (approximately 100m) and shows the terrestrial dose rate of the NSW DMR, Discovery 2000, 1995, S.E. Darling Basin, AREA G. The data used to produce this grid was acquired in 1995 by the NSW Government, and consisted of 42604 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Geology and hydrocarbon prospectivity of the deepwater Otway and Sorell basins, offshore southeastern Australia

As part of the Offshore Energy Security Program (2007-2011), Geoscience Australia (GA) undertook an integrated regional study of the deepwater Otway and Sorell basins to improve the understanding of the geology and petroleum prospectivity of the region. Major outputs of this study include:

New interpretations of basement architecture and structural fabric resulting in the recognition of the Avoca-Sorell Fault System as a major control on sedimentary basin development,
Extension of the tectonostratigraphic framework of Krassay et. al. (2004) into the deepwater Otway and Sorell basins, leading to new insights into their structural and accommodation histories of both basins, and 
Petroleum systems modelling indicating that these basins are mature for oil and gas generation.

Calibration and data processing for airborne gamma-ray spectrometry

The shape and intensity of multichannel airborne gamma-ray spectra are influenced by many variables.  The role of data processing is to correct the data for those influences not related to the geology, and to transform the observed spectra to equivalent concentrations of radioelements in the ground.  The data need to be corrected for dead time, energy drift, and background radiation before being inverted to elemental count rates.  The elemental count rates are then corrected for variations in the terrain clearance of the detector and reduced to elemental concentrations in the ground.  Statistical errors in the raw data are propagated by the data processing procedures.  The removal of background radiation increases the fractional errors for each of the potassium, uranium and thorium window count rates.  The fractional errors in the potassium and uranium window count rates are also amplified by the stripping procedure.  Large errors can be introduced into the data through the height correction procedure if radon background is not adequately removed.  Radon background can be adequately removed using a spectral-ratio method.

Darwin Harbour Habitat Mapping Program: Predicted standard error for interpolated surface of the element Aluminium

This resource contains a predicted aluminium standard error grid for the greater Darwin Harbour region as part of a baseline seabed mapping program of Darwin Harbour and Bynoe Harbour. This project was funded through offset funds provided by an INPEX-led Ichthys LNG Project to the Northern Territory Government’s Department of Environment and Natural Resources (NTG-DENR) with co-investment from Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS). The intent of this program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps and information to underpin marine resource management decisions. The predicted aluminium standard error grid was derived from a compilation of multiple surveys undertaken by GA, AIMS and NTG-DENR between 2011 and 2017, including GA0333 (Siwabessy et al., 2015), GA0341 (Siwabessy et al., 2015), GA0351/SOL6187 (Siwabessy et al., 2016), GA4452/SOL6432 (Siwabessy et al., 2017), GA0356 (Radke et al., 2017), and GA0358 and GA0359 (Radke et al., 2018), adding to those from previous surveys GA4425 and GA0333 collected by GA, AIMS, NTG-DENR and Darwin Port Authority.

Frome uranium Province, South Australia: Systems analysis and potential for major basin-hosted uranium deposits

Cenozoic basins of the Lake Frome region in South Australia host the Beverley in-situ recovery uranium mine as well as the Honeymoon, Four Mile, Oban, and Goulds Dam deposits and recently discovered Pepegoona prospect several kilometres to the north of Beverley.  Most deposits occur in organic-rich sands and silts of the Eocene Eyre Formation or Miocene Namba Formation (Beverley).  However, the recognition of Eromanga Basin host rocks at the Four Mile West deposit (Heathgate Resources, pers. comm., 2009) extends the age range of host stratigraphic units into the Mesozoic.  We define the Frome Uranium Province as the 3-dimensional volume encompassing known and potentially mineralised areas of Cenozoic and Mesozoic basins in the Lake Frome region, constrained on three sides by Proterozoic inliers (Fig. 1).  The northern extent of the metallogenic province is unknown; recent discovery of anomalous uranium in Cenozoic sediments near Moomba (Crescent Gold Ltd, September 2009, www.crescentgold.com) points to the potential of the Lake Eyre Basin for uranium mineralisation well to the north of Lake Frome.

Flood risk in South East Queensland, Australia

Geographical information systems (GIS) have been used to model building flood damage in South East Queensland. The research shows that if a flood with a 1% annual exceedence probability (AEP) occurred simultaneously in all rivers in the region, 47 000 properties would be inundated, with about half of the properties likely to experience overfloor flooding. 
90% of affected properties are located in the Brisbane-Bremer River system and the Gold Coast catchment.  89% of properties affected by flooding are residential.  Nearly 60% of the residential flood damage is located in the Brisbane-Bremer River system, with damage estimated to be highest in those areas which historically have suffered high flood losses. Equivalent average damage per residential building is highest in the Gold Coast catchment. 
If the cost of the actual damages were to be spread among all residential buildings in South East Queensland, than the equivalent flood damage would be 1.09% damage from a flood with a 1% AEP.
