Cooper Basin Seismic, Gravity (P196743), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Cooper Basin Seismic, Gravity (P196743) contains a total of 1889 point data values acquired at a spacing between 600 and 800 metres. The data is located in QLD, SA and were acquired in 1967, under project No. 196743 for Delhi Petroleum Pty Ltd.

p-rock (Probability of Rock) Grids - 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 p-rock (probability of rock) grids produced from the angular response curves from the multibeam backscatter data. The extraction of angular response curves from the raw Simrad multibeam data was achieved using the multibeam backscatter CMST-GA MB Process v10.10.17.0 toolbox software co-developed by the Centre for Marine Science and Technology (CMST) at Curtin University of Technology and Geoscience Australia (described in Gavrilov et al., 2005a, 2005b; Parnum, 2007). A number of corrections were introduced to the data and the angular response curves were produced as the average response curve within the adopted sliding windows in which port and starboard swath were processed separately as part of the process of the removal of the backscatter angular dependence. Angular backscatter response curves were compared to the reference response of rock/hard bottom (inferred grabs and cores) using the Kolmogorov-Smirnov goodness of fit to estimate the probability (p-value) of rock (p-rock). Finally, the IDW interpolation technique was used to produce a continuous layer of the p-value of hard bottom for each study area.

Crustal structure of the Precambrian terrains of northwest Australia from seismic refraction data

The crust of the Pilbara Craton is 28-33 km thick, and its boundary with the upper mantle dips south at slightly less than one degree. The southern edge of the craton is marked by a sharp increase in crustal thickness about 40 km south of the Sylvania Dome in the east and along the northern boundary of the Ashburton Trough in the west. Seismically, the crust has two layers, an upper one with P-wave velocity 6.0-6.1 km s^-1, and a lower of 6.4-6.6 km s^-1. The boundary between them is depressed beneath the deepest part of the Hamersley Basin, and rises along the southern part of the basin and craton, beneath a topographic ridge of higher grade metamorphic rocks. The velocities in the lower crustal layer are highest along the southern part of the Hamersley Basin, an area known to have been depressed during the formation and filling of the basin, and then uplifted. The crust of the northern Yilgarn Craton is at least 50 km thick and, seismically, has three layers. The uppermost layer has P-wave velocities of 6.1-6.2 km s^-1, the middle layer, at 10-16 km depth, 6.4 km s^-1, and the lowest, at 32 km depth, 6.7-7.0 km s^-1. A zone of crust, about 50 km wide, along the northern margin of the craton was extensively reworked during Proterozoic orogenesis, and is now characterised by thinner crust than the rest of the Yilgarn Craton, extensive granitoid emplacement, intense deformation and folding of the upper crustal rocks, and low gravity values. The Capricorn Orogen between the cratons is marked by high velocities in the lower crust, probably caused by dense mafic intrusions or a higher metamorphic grade. The seismic layering within the crust is most likely caused by increasing metamorphic grade with depth. The crust is probably of average acid to intermediate chemical composition, and has a low metamorphic grade at the surface. The velocities are attributed to metamorphic grade increasing to felsic granulite at 9-16 km depth, and garnet granulite at 32 km depth in the Yilgarn Craton.

Australia’s Future Energy Resources (AFER) Project: Regional hydrogeology of the Pedirka and western Eromanga basins

As part of the EFTF Program, Geoscience has completed a 4-year multi-disciplinary study to investigate the energy resource potential of selected onshore basins within central Australia under the Australia’s Future Energy Resources (AFER) Project. A key component of the AFER Project has been a qualitative and quantitative play-based assessment of hydrocarbon resources and geological storage of CO2 (GSC) potential within the Pedirka and western Eromanga basins (Bradshaw et al., 2024a). This study has provided a regional interpretive data set which includes regional seismic and well log interpretations (Bradshaw et al.&nbsp;2024b, 2024c); depth-structure and isochore maps for 14 play intervals (Iwanec et al., 2024); gross-depositional environment maps for 14 play intervals (Bradshaw et al., 2024c); and petrophysical analysis of wireline log data from 23 wells (Spicer et al., 2024). This report provides a high-level summary of the hydrogeology of Pedirka and western Eromanga basins as background information for the other assessments and some findings from the 3D models that may inform future understanding of the hydrogeology of these basins. 

The assessment area extends over ~210,000 km2 across the Northern Territory, South Australia and Queensland (Figure 1). Much of the assessment area underlies national parks in South Australia and Queensland. No petroleum exploration access is allowed in the Munga Thirri Simpson Desert Conservation Park or the Witjira National Park (Dalhousie Springs area) in South Australia or Munga Thirri National Park in Queensland (Figure 1).

The AFER assessment area is situated within the Kati Thanda-Lake Eyre surface water catchment. The catchment’s arid climate and ephemeral river flow regime (Evans et al., 2024) makes groundwater a critical source of water for the environment, industry and communities, especially during dry periods. Groundwater dependent features in the region include water supplies for communities, industry and pastoral stations, as well as springs and other groundwater dependent ecosystems. Groundwater resources are managed by state and territory jurisdictions (see: NT Government, 2013; Queensland Government, 2017, SA Government, 2021). Across the three jurisdictions, the most important groundwater resources are those of the western Eromanga Basin (a part of Great Artesian Basin or GAB). In collaboration with state jurisdictions the Commonwealth provides a cross-jurisdictional policy framework for the GAB as well as the Lake Eyre surface water basin (DCCEEW, 2024). Key management goals include maintaining artesian pressures, water quality and viability of GAB dependent ecosystems, including springs.&nbsp;

MRTAS Western Tasmania ppm thorium 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 thorium grid has a cell size of 0.00042 degrees (approximately 41m) and shows thorium element concentration of the Western Tasmania, Tas, 2001 (WTRMP Area C) in units of parts per million (or ppm). The data used to produce this grid was acquired in 2001 by the TAS Government, and consisted of 44149 line-kilometres of data at 200m line spacing and 80m terrain clearance.

Gairdner - TMI RTP 1VD grid (AWAGS)

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. .
 This Gairdner - TMI RTP 1VD grid (AWAGS) is the first vertical derivative of the TMI RTP grid of the Gairdner Airborne Magnetic Radiometric and DEM survey, SA, 2018 survey.
This grid has a cell size of 0.0004 degrees (approximately 41m) , and given in units of nT per metre (nT/m).  The data used to produce the TMI grid was acquired in 2018 by the SA Government, and consisted of 104788 line-kilometres of data at 200m line spacing and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey. A first vertical derivative was calculated by applying a fast Fourier transform (FFT) process to the TMI RTP grid of the Gairdner Airborne Magnetic Radiometric and DEM survey, SA, 2018 survey to produce this grid. This grid was calculated using an algorithm from the INTREPID Geophysics software package. This grid shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The grid can also be used to locate structural features such as dykes.

Early Australian gravity observations

Since the publication of Gravimetry in Australia 1819-1976 (Dooley and Barlow, 1976), our attention has been drawn to the paper by Day (1966) on early Australian geophysical history. We apologise for our ignorance of this interesting paper, which refers to many of the nineteenth-century gravity measurements listed in our Table I, and gives further details of the observers and the background to the measurements. In Table 1, we had compared the results of the older measurements with currently accepted values of gravity. For completeness, we analyse below a notable series of measurements at Parramatta between 1821 and 1828, which we omitted from our history.

AUSGeoid98 v.1.0 data files: Onslow (sf50-05)

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.
