Arltunga Nappe Detailed Gravity (P197308), 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 Arltunga Nappe Detailed Gravity (P197308) contains a total of 213 point data values acquired at a spacing of 1000 metres. The data is located in NT and were acquired in 1973, under project No. 197308 for Bureau of Mineral Resources (BMR).

Cobar P5009 EXT 5 digital elevation model radar grid

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Cobar P5009 EXT 5 digital elevation model radar grid is elevation data for the Cobar Magnetic and Radiometric Survey, 2021. This survey was acquired under the project No. 5009 for the geological survey of NSW. The grid has a cell size of 0.00039074 degrees (approximately 40m).  This grid contains the ground elevation relative to the geoid for the Cobar Magnetic and Radiometric Survey, 2021. It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

AUSGeoid98 v.1.0 data files: Victoria River Downs (se52-04)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files.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.

Site Characterization for ANSN Stations Using the Ellipticity Curve Inversion of Microtremor data

The site-specific shear velocity profile for the top 30 m, VS30, is the most popular geotechnical parameter to characterize local site conditions. Shear velocity measurements are not available for the majority of earthquake-recording stations in the Australian National Seismograph Network (ANSN). Accordingly, the lack of available shear-wave velocity data in Australia makes it difficult to benchmark amplification effects to a reference site condition. One inexpensive and relatively efficient method that can be used to analyse single-station ambient noise data is the Horizontal to Vertical Spectral Ratio (HVSR) method. We used OpenHVSR software for the inversion of the HVSR curves. The S-wave velocity structure and VS30 results derived from the inversion process of the HVSR curves are in a good agreement with the previous Spatial Autocorrelation (SPAC) study for the ANSN stations and can be used as a fast and inexpensive technique to measure the VS30 for site classification purposes.&nbsp;

This Abstract was submitted/presented to the 2022 Australian Earthquake Engineering Society (AEES) Conference 24-25 November (https://aees.org.au/aees-conference-2022/)

Outcrop and drill core gamma-ray logging integrated with sequence stratigraphy: examples from Proterozoic sedimentary successions of northern Australia

Outcrop and core gamma-ray logs have been successfully used to correlate Proterozoic units in northern Australia. This paper highlights the benefits of integrating gamma-ray data and traditional sedimentology for defining large-scale depositional cycles and depositional geometry. Gamma-ray logs of outcrop and cored intervals provide excellent stratigraphic and sedimentological information for areas where conventional down-hole geophysical surveys are lacking.  Both total count (scintillometer) gamma-ray profiles and spectral gamma-ray profiles enable recognition of subtle changes in lithology and sedimentary cyclicity that might have been missed during customary section measuring. Lithofacies described from measured sections and core may be characterised by their gamma-ray signatures, and the signatures may then be used as proxies for down-hole gamma-ray logs obtained from the subsurface where direct lithological information is sparse or absent. The integration of traditional lithostratigraphic descriptions with surface and subsurface gamma-ray logs results in a more robust and sophisticated stratigraphic framework than either data set can yield independently. Use of sequence stratigraphic principles enables gamma-ray log trends and their stacking patterns to be interpreted as part of larger sedimentary cycles that reflect changes in sediment supply and relative sea level. Abrupt shifts in gamma-ray values occur at important stratigraphic surfaces that define sedimentary sequences of various scales. Systematic variations in sedimentary thickness and gamma- ray stacking patterns between areas are related to changes in depositional geometry of sequences. Regional mapping of stratigraphic surfaces and sequences by the correlation of vertical gamma-ray profiles and corresponding descriptive logs allows a predictive chronostratigraphic framework to be constructed for a region.

The 2017 Offshore Acreage Release Areas: Petroleum Geological Overview

In 2017, 21 new offshore petroleum exploration areas have been released. The majority of the areas are located along the North West Shelf spanning the Westralian Superbasin from the Bonaparte Basin in the north-east to the Northern Carnarvon Basin in the south-west. New areas have been released in offshore south-eastern Australia with new opportunities provided in the Otway, Bass and Gippsland basins. Two large areas in the northern Perth Basin, an offshore frontier, complete the 2017 Acreage Release. All Release Areas are supported by industry nominations and one new cash bid area has been offered in the Dampier Sub-basin.
Geoscience Australia continues to support industry activities by acquiring, interpreting and integrating pre-competitive datasets that are made freely available as part of the agency’s regional petroleum geological studies. A new regional 2D seismic survey was acquired in the Houtman Sub-basin of the Perth Basin, forming the basis of the latest prospectivity study carried out by Geoscience Australia. The results of the study are presented in the technical program of the 2017 APPEA conference. A wealth of seismic and well data, submitted under the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGSSA) are made available through the National Offshore Petroleum Information Management System (NOPIMS). Additional datasets are accessible through Geoscience Australia’s data repository.
Presented at the 2017 Australian Petroleum Production &amp; Exploration Association (APPEA) Conference.

National Bathymetry Priorities

This dataset comprises an amalgamation of State, Territory and Commonwealth priorities in terms of Seabed mapping as of February 2017. Data that were identified as important for: safe navigation, environmental baseline assessment, resource competition and baseline data, and urgently required to support policy and government decisions were given priority. Agencies then ranked their priority areas 1 – very high/high (red), 2 – moderate (blue), and 3 – low (green), based on the need for the data and the impact of the data. These priority sets were compiled by Geoscience Australia and submitted to the Australian Hydrographic Office (AHO) for consideration as supplementary material for their "Hydroscheme" acquisition plan.
