GSWA Perth Basin South Uranium 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.
This radiometric uranium grid has a cell size of 0.00083 degrees (approximately 86m) and shows uranium element concentration of the Perth Basin South, WA, 2011 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2011 by the WA Government, and consisted of 80718 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Aftershock probability model for Australia

After a main shock, the magnitude and timing of smaller aftershocks follow characteristic distributions known as Gutenberg-Richter and Omori laws, respectively. Based on these empirical laws, Reasenberg and Jones (1989) proposed a model to estimate the probability of earthquakes during an aftershock sequence as a function of time and magnitude. In this study, the parameters of the Reasenberg and Jones aftershock magnitude-time distribution are derived using the Australian instrumental earthquake catalogue (1900-2010). Two sets of model parameters are determined: sequence-specific parameters determined for well recorded aftershock sequences and generic parameters determined for a stack of events with magnitudes larger than or equal to 5. Both sets are found to be comparable to similar studies in other regions of the world. The spatial variation of model parameters is also studied and it is found that aftershock sequences in Southeastern Australia are less productive than sequences in Western Australia. Applicability of the derived generic parameters to forecast aftershock rates in Australia is verified using recent aftershock sequences that were not included in the earthquake catalogue such as the 2012 Gippsland earthquake.

Organic Geochemistry of Core Sediments - Caswell Sub-basin, Browse Basin Marine Survey (GA0345/GA0346/TAN1411)

Geoscience Australia (GA) conducted a marine survey (GA0345/GA0346/TAN1411) of the north-eastern Browse Basin (Caswell Sub-basin) between 9 October and 9 November 2014 to acquire seabed and shallow geological information to support an assessment of the CO2 storage potential of the basin. The survey, undertaken as part of the Department of Industry and Science's National CO2 Infrastructure Plan (NCIP), aimed to identify and characterise indicators of natural hydrocarbon or fluid seepage that may indicate compromised seal integrity in the region. 
The survey was conducted in three legs aboard the New Zealand research vessel RV Tangaroa, and included scientists and technical staff from GA, the NZ National Institute of Water and Atmospheric Research Ltd. (NIWA) and Fugro Survey Pty Ltd. Shipboard data (survey ID GA0345) collected included multibeam sonar bathymetry and backscatter over 12 areas (A1, A2, A3, A4, A6b, A7, A8, B1, C1, C2b, F1, M1) totalling 455 km2 in water depths ranging from 90 - 430 m, and 611 km of sub-bottom profile lines. Seabed samples were collected from 48 stations and included 99 Smith-McIntyre grabs and 41 piston cores. An Autonomous Underwater Vehicle (AUV) (survey ID GA0346) collected higher-resolution multibeam sonar bathymetry and backscatter data, totalling 7.7 km2, along with 71 line km of side scan sonar, underwater camera and sub-bottom profile data. Twenty two Remotely Operated Vehicle (ROV) missions collected 31 hours of underwater video, 657 still images, eight grabs and one core.
This catalogue entry  refers to geochemical data on piston core sediments collected during the GA0345/TAN1411 marine survey in the Browse Basin. These include concentrations of interstitial gases (C1 to C5, CO2) and high-molecular weight hydrocarbons.

Deep Structure of the Browse Basin Region, North West Shelf Australia: Cruise Proposal

The Browse Basin underlies the outer shelf and upper slope of the central part of Australia'sNorth West Shelf, in water depths of 100-1000 m. Although the North West Shelf is generallyconsidered to be one of Australia's most heavily explored offshore regions, there aresignificant portions of it, such as the offshore Canning and Browse Basins, that remain under-explored. Relatively little is known of the primary structural architecture of the basin systemsof the North West Shelf, and the influence of that architecture on the occurrence ofhydrocarbons. The Browse Basin study (AGSO Project 121.28 - Basin development andhydrocarbon potential of the Browse Basin and adjacent margin) is part of a major AGSOregional research program over the north western Australian margin, and has the following main objectives:
1) Determine the regional structural framework of the Browse Basin and its relationship toadjacent features such as the Vulcan Sub-basin, Rowley Sub-basin, Scott Plateau andKimberley Block;
2) Define the broad deep-crustal structure of the region and develop a model explaining the
tectonic, subsidence and thermal history of the basin in relation to the development of thecontinental margin and adjacent ocean basin (the Argo Abyssal Plain);
3) Assess the effects of deep structure and reactivation on the development of knownpetroleum accumulations.
To address these objectives it is proposed that RV Rig Seismic be used to acquire about 3200km (up to a maximum of 3600 km depending on contingencies) of deep seismic and othergeophysical data along 11 lines tying 18 exploration wells in the Browse Basin/Scott Plateauregion. The survey will also tie into the 1990 Vulcan Sub-basin survey (98) to the northeast,and the forthcoming survey over the offshore Canning Basin to the southwest.
In line with the Marine Geoscience and Petroleum Geology Program's (MGPGP's) most recentdeep seismic surveys over the North West Shelf, the Browse Basin survey will use a 4800 mstreamer, configured with 192 x 25 m active groups; data will be recorded with a 16 secondrecord length, and a 2 millisecond sample interval; the seismic source will be dual airgunarrays with a total capacity of 49 litres, and will be fired every 50 metres to give 48-fold CDPcoverage; and navigation will be by differential GPS. These parameters are the same as usedon two surveys over the northern Carnarvon Basin (SNOWS-1 and SNOWS-2) and threesurveys over the Bonaparte Basin - Timor Sea, and will also be used on the SNOWS-3 surveyover the offshore Canning Basin, following the Browse survey. Using these parametersAGSO has consistently recorded reflections down to 8-12 seconds two-way time (12-20 kmdepth), as well as obtaining good resolution in the upper 6 seconds of data, which is normallythe limit recorded by industry.

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 Nabberu combined dose rate grid geodetic has a cell size of 0.00083 degrees (approximately 88m) and shows the terrestrial dose rate of the Nabberu North-South merge, 1996. The data used to produce this grid was acquired in 1996 by the WA Government, and consisted of 44375 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Carnarvon Basin North, WA, 2011 (P1234), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data 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.
 These line dataset from the Carnarvon Basin North, WA, 2011 survey were acquired in 2011 by the WA Government, and consisted of 107266 line-kilometres of data at 400m line spacing and 60m terrain clearance.
