AUSGeoid98 v.1.0 data files:  (sk52-07)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

Duchess E-W Seismic Line Gravity (P199410), 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 Duchess E-W Seismic Line Gravity (P199410) contains a total of 134 point data values acquired at a spacing of 240 metres. The data is located in QLD and were acquired in 1994, under project No. 199410 for Australian Geological Survey Organisation (AGSO).

MRTAS Fingal tmi grid geodetic

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 MRTAS Fingal tmi grid geodetic has a cell size of 0.0005 degrees (approximately 49m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1993 by the TAS Government, and consisted of 16797 line-kilometres of data at 200m line spacing and 80m terrain clearance.

Legal Traceability of GPS Positions in Australia

The national measurement system in Australia ensures a basis for legally traceable, consistent and internationally recognised measurements.  With the growing societal dependency on GPS, the need for the legal traceability of GPS positions with respect to the Australian Datum - the Geocentric Datum of Australia 1994 (GDA94) -- has become increasingly apparent. In the interest of ensuring consistency of positions derived from private and government Continuously Operating Reference Stations (CORS),Geoscience Australia maintains an appointment as a legal metrology authority in accordance with the National Measurement Act 1960 and provides legally traceable positions.  This presentation will overview Geoscience Australia's approach to the legal traceability of GPS positions, the process of legal certification including: (1) the basic requirements for requesting certification; (2) quality standards and the quality management system of the position verification processes. The structured maintenance and continual improvement program for the verifying laboratory will also be introduced.

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south.

Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD.

Guide to prospecting for uranium, Darwin - Katherine area, Northern Territory

Since 1949 a considerable amount of geological and geophysical investigation as well as diamond drilling and some underground development has been undertaken in the search for uranium ore in the Darwin-Katherine region, and in the course of this work information has been gained which, it is thought, may be of interest to prospectors and companies who are now beginning to pay considerable attention to the possibilities of the area, but have had little or no experience of prospecting for uranium in the Katherine-Darwin region. Investigations of the area by the Bureau, by private companies, and by prospectors [are] now proceeding more vigorously than ever, and without doubt a good deal more remains to be found out concerning the uranium deposits of this province. In these circumstances the notes supplied below are put forward tentatively as being some facts known to the present writer at this time (July, 1953) as well as some more controversial opinions. It is expected that more information will be made available as the investigation proceeds. (The following notes should be read in conjunction with Pamphlet No. 3 (Radioactive Mineral Deposits) of the Bureau of Mineral Resources, Geology and Geophysics and a copy of the Mineral Map (NT32B-4) would greatly aid in their understanding).

Rock-Eval pyrolysis data from wells of the Canning Basin, Australia: Destructive Analysis Report 2020-004

The onshore Canning Basin in Western Australia is the focus of a regional hydrocarbon prospectivity assessment being undertaken by the Exploring for the Future (EFTF) program; an Australian Government initiative dedicated to increasing investment in resource exploration in northern Australia. The four-year program led by Geoscience Australia focusses on the acquisition of new data and information about the potential mineral, energy and groundwater resources concealed beneath the surface in northern Australia and parts of South Australia. As part of this program, significant work has been carried out to deliver new pre-competitive data including new seismic acquisition, drilling of a stratigraphic well and the geochemical analysis of geological samples recovered from exploration wells. 
As part of this comprehensive analytical program, TOC and Rock-Eval pyrolysis analyses were undertaken by Geoscience Australia on selected rock samples from eight wells of the Canning Basin to establish their hydrocarbon-generating potential and thermal maturity. These samples were selected to infill gaps in the existing open file data with a particular focus on the Lower Ordovician Nambeet Formation for comparison with samples from the Waukarlycarly 1 well.

Hydrogeological datasets for Cenozoic geology, hydrogeology, and groundwater systems of the Kati Thanda - Lake Eyre Basin

This data package contains the main hydrogeological datasets compiled, analysed, developed, and used for the Geoscience Australia project that investigated the Cenozoic geology, hydrogeology, and groundwater systems of the Kati Thanda - Lake Eyre Basin in central Australia. This work, which was published as Geoscience Australia Record 2024/05 (Evans et al. 2024), was delivered as part of the National Groundwater Systems project in the Exploring for the Future program.

The hydrogeological and groundwater data includes new aquifer and aquifer province attribution for many thousands of groundwater bores, large-scale compilations of existing water level, salinity, and hydrogeochemical data, and new mapping of regional watertable trends and depth to standing water across the basin. These data are represented within the Geoscience Australia Record as various maps and related diagrams.
