Ginan: Geoscience Australia's Positioning Toolkit

Precise positioning based on constellations of navigation satellites brings significant economic and social benefits to Australia. Precise positioning reduces fertiliser and chemical spray waste in agriculture. It improves the efficiency of operations in large mine sites. Precise positioning improves safety in aircraft operations and can even give added freedom of movement to sight impaired people. The rationale behind the Ginan project is to develop the software and data products to allow everybody in Australia to enjoy the benefits of precise positioning through the creation of new services and products, and in doing so drive economic growth enhancing Australia's prosperity.

AUSGeoid98 v.1.0 data files:  (sc48-08)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

Comparison of earthquake source spectra and attenuation in eastern North America and southeastern Australia

The paucity of ground-motion data in Stable Continental Regions (SCRs) remains a key
limitation when developing relations that seek to predict effects of strong ground-shaking
from large damaging earthquakes. It is desirable to combine data from more than one SCR
in order to increase database size, but this raises questions as to whether the source and
attenuation properties of the SCRs are equivalent. We merge recently - compiled spectralamplitude
databases from small-to-moderate events (moment magnitudes 2.0&lt; - 5.0&lt;) in
both southeastern Australia and eastern North America in order to compare the key
characteristics of ground motion in these two regions. Both are SCRs, but are widely
separated, spatially and in tectonic history.

Geelong Sorrento Nowingi Robinvale Weimby 1:100,000 Infill (P199834), 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 Geelong Sorrento Nowingi Robinvale Weimby 1:100,000 Infill (P199834) contains a total of 1860 point data values acquired at a spacing between 750 and 3000 metres. The data is located in VIC and were acquired in 1998, under project No. 199834 for None.

Waterloo, NT, 2001 (P1019), 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 Waterloo, NT, 2001 survey were acquired in 2001 by the NT Government, and consisted of 68733 line-kilometres of data at 400m line spacing and 80m 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.

A sandstone breccia, formed by quasi-liquid deformation, from the Amadeus Basin, Northern Territory

A prominent sandstone breccia crops out in the Pacoota Sandstone, Western MacDonnell Ranges, Northern Territory. The breccia occurs as discontinuous lenses which grade laterally, through incipient breccia and disrupted sandstone beds, into the enclosing sandstone sequence. This sequence consists of interbedded well-sorted silicia-cemented and poorly sorted friable quartzose sandstones; these two sandstone types also constitute, respectively, the clasts and matrix of the breccia. The clasts are rectangular (joint-bounded) and broken rectangular in shape, ranging up to 1 m in length. The matrix is predominantly massive, but convolute bedding is locally present. Similar sandstone breccias are known from three other localities in the region, all at the same stratigraphic level within the Pacoota Sandstone. Petrographic data indicate that the clast sandstone was cemented and strained prior to brecciation, whilst the matrix sandstone retained a largely cohesionless state and failed in a quasi-liquid manner. It is concluded that the brecciation occurred in situ at a considerable depth in a sedimentary pile, and resulted from the rotation and fragmentation of joint blocks of silica-cemented sandstone in the interbedded mobile matrix sandstone. Pore-water pressures are thought to have played an important role in the mobilization of the matrix sandstone.

L049 Amadeus Basin Southern Margin seismic survey, NT, 1961

The Bureau of Mineral Resources Seismic Party No. 2 conducted a survey from 15th May to 25th August 1961 in the Amadeus Basin. Reflection and refraction traverses were shot at intervals, along or near the Alice Springs/Port Augusta railway line, from Polhill in the north to Finke in the south. In broad terms the object of the survey was to obtain across the Amadeus Basin a north-south seismic cross-section that would aid
in investigating the stratigraphic cross-section and structural relations especially on the southern margin of the Basin. Access and drilling problems caused the progress of the survey to be slow. The statistics of the operation are included in three appendices. During the course of the seismic survey, the Bureau also made gravity surveys covering the area; gravity-meter readings were made along all seismic traverses.

Direct-use of Geothermal Energy: Opportunities for Australia

Educational factsheet about direct-use of geothermal energy - what it is, why do it, where can it be done, international figures for direct-use of geothermal energy and opportunities for using geothermal energy directly in Australia.
Mini-abstract on factsheet as follows:
Geothermal energy is a natural source of heat contained within the Earth, and it can be extracted and used either indirectly to generate electricity, or directly for heating applications. There are some examples of geothermal direct-use projects in Australia already and there is significant potential for additional domestic, industrial and commercial applications.
