AUSGeoid98 v.1.0 data files:  (se55-12)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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.

An Audit of Selected Offshore Petroleum Exploration Wells in the Otway Basin, Southeastern Australia

This Record presents a summary of an analysis of 21 offshore Otway Basin wells (Appendix 1) based on data provided in open file Well Completion Reports (WCRs) and Geoscience Australia online databases. Additional data and interpretations are drawn from the large body of published material on the basin. Analysis was inhibited in some cases by the quantity of data in WCRs, specifically the paucity of maps provided in the interpretive sections. Fortunately, most well analyses appear to have a determination of the reason/s for failure that is reasonably clear even without maps.
The end product is primarily focused on individual well results, specifically success and failure analysis. To put the wells in a geological perspective, the introduction outlines briefly the regional geologic setting, distilling the ideas of many workers through the basin's exploration history. The final section presents a petroleum systems focused summary of the main findings of the work. From this, critical risks have been identified and areas of higher or additional potential have been indicated.

Bendigo Infill (P199636), 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 Bendigo Infill (P199636) contains a total of 912 point data values acquired at a spacing of 1500 metres. The data is located in VIC and were acquired in 1996, under project No. 199636 for None.

Sir Samuel, WA, 1993 (P596), 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 Sir Samuel, WA, 1993 survey were acquired in 1993 by the WA Government, and consisted of 47075 line-kilometres of data at 400m line spacing and 100m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Reports on the Geology of the Federal Capital Site

In 1911 a geological survey of the Canberra Federal City site was completed with a map.  The rocks composing the site are somewhat contorted and folded sedimentary series of sandstones and quartzites, shales, slates, limestones, and volcanic tuffs, and this has subsequently been intruded by an igneous series, consisting principally of quartz-phorphyries and quartz-felsites.

Australian Geomagnetic Reference Field (2000 revision AGRF00) (National Geoscience Dataset)

The AGRF is a numerical model of the earths magnetic field over the Australian region. The model can be used to generate single point or gridded values of any element of the magnetic field (e.g., magnetic declination, inclination, or total intensity) together with annual change estimates. The AGRF is valid only for the Australian region, where it is considered to be more accurate than global models such as the International Geomagnetic Reference Field. The version here, AGRF00, is valid for years between 1995 and 2005. AGRF is also provided online. The user must input the latitude, longitude, and elevation of a site together with the year. 
http:/www.agso.gov.au/geophysics/geomag/rf/agrfform.html
FURTHER INFORMATION:- 
The AGRF represents a combination of the earths main (core) field and the long wavelength crustal field. Local crustal anomolies and disturbances which are external in origin (e.g. magnetic storms) are not represented. The model is based on all available
ground, airborne, and satellite vector survey data. Magnetic observatory
and repeat station survey data from the region are used to update
these main/crustal field data sets and to provide the estimates of
annual change. The region modelled is a spherical cap of radius 28
deg centred at 24 degS, 135 degE. Model values outside a radius of
24 deg are considered to be unreliable because of edge effects.

Cloncurry Magnetotelluric Survey

Geoscience Australia (GA) and the Geological Survey of Queensland (GSQ) conducted the Cloncurry Magnetotelluric (MT) survey. MT data (0.001 s to 1000 s in period) at 476 sites with a grid spacing of 2km were acquired over an approximate 40km x 60km area in the Cloncurry region from July to November 2016.  The survey area covers the eastern margin of the Mount Isa Block situated to the west of the Eromanga Basin. The MT data can image the thickness of cover, the basement architecture and the crustal architecture in this area that has high resource exploration potential. Data QA/QC were performed during the data acquisition stage of the survey.  This release includes processed MT data and a data acquisiton report written by the contractor.  Details on the data processing, data analysis, and modelling/inversion of the data will be released as a comprehensive report at a later date.

Younger geology was interpreted by Geoscience Australia (GA), based on GA's 1:1,000,000 scale Surface Geology of Australia (2012).
Descriptions of mapped geological units are housed in Geoscience Australia's Stratigraphic Names Database, which can be linked to other geoscience databases in Geoscience Australia.

Integrated geophysical modelling for salt mapping in the Polda Basin, South Australia

The integrated use of seismic and gravity data can help to assess the potential for underground hydrogen storage in salt caverns in the offshore Polda Basin, South Australia. Geophysical integration software was trialled to perform simultaneous modelling of seismic amplitudes and traveltime information, gravity, and gravity gradients within a 2.5D cross-section. The models were calibrated to existing gravity data, seismic and well logs improving mapping of the salt thickness and depth away from well control. Models included known salt deposits in the offshore parts of the basin and assessed the feasibility for detection of potential salt deposits in the onshore basin, where there is limited well and seismic coverage. The modelling confirms that candidate salt cavern storage sites with salt thicknesses greater than 400-500 m should be detectable on low altitude airborne gravity surveys. Identification of lower cost onshore storage sites will require careful calibration of gravity models against measured data, rather than relying on the observation of rounded anomalies associated with salt diapirism. Ranking of the most prospective storage sites could be optimized after the acquisition of more detailed gravity and gradiometry data, preferably accompanied by seismic reprocessing or new seismic data acquisition.
