AUSGeoid98 v.1.0 data files:  (sc50)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

Proterozoic geology of the northwest Paterson Orogen, Western Australia: Prospectivity, possibilities, progress, and the Permian problem

This address was presented at the Central Australian Basins Symposium, Alice Springs, Northern Territory, 16-18 August, 2005.
The Neoproterozoic sedimentary successions of the Centralian Superbasin (Walter et al 1995) in the northwest Paterson Orogen, Western Australia, are host to several major mineral systems including: gold-copper (Telfer, Magnum), base metal (Nifty, Maroochydore) and uranium (Kintyre). Geological mapping of the region by Bagas and others (1991-2003) at 1:100 000 scale is being followed by a new Geoscience Australia and Geological Survey of Western Australia National Geoscience Agreement project, to acquire new airborne geophysical data, and develop an understanding of the depositional history of the Neoproterozoic Paterson stratigraphy, its subsequent deformation(s) and its mineral systems. This project will investigate and integrate sedimentary facies, geophysical properties, structural elements and other post-depositional processes, such as granite emplacement, to understand their relationships to the mineral systems in the region. The suggested links of Bagas et al (1995, 1999) between the Paterson Neoproterozoic succession and the Centralian Superbasin will also be investigated.

Some aspects of Carboniferous biostratigraphy in eastern Australia: a review

Progress in detailed mapping and biostratigraphical work in New South Wales has resulted in a revision of the current correlations of the Carboniferous rocks in eastern Australia (Jones et al., 1973). Revision of the brachiopod zonation (Roberts, 1975) indicates the widespread distribution of the Tulcumbella tenuistriata. Schellwienella cf. burlingtonensis. Delepinea aspinosa, Rhipidomella fortimuscula. Marginirugus barringtonensis and Levipustula levis Zones; the absence of the Spirifer sol and Orthotetes australis Zones in Queensland; and the restriction of the latter Zone to the Hunter Valley region of New South Wales. The brachiopods fauna are largely endemic, and where ammonoids, conodonts, and foraminifera are available, attempts have been made to date them in terms of the standard European series. The lower three brachiopod zones as dated from the goniatite evidence are mainly Tournaisian in age (tenuistriata Zone = Tnlb or cul; sol Zone = Tn2; cf. burlingtonensis Zone = Tn3a to Vla of CuII y). Although these ages are broadly consistent with those of the conodont evidence, in detail, there is an apparent discrepancy between the ages of the sequence of gnathodid faunas in the Schellwienella cf. bulingtonensis Zone at Carellan and Rouchel. A conflict between the late Visean - early Namurian (V3a-EI) ages suggested by the goniatites for the younger brachiopod zones (australis, aspinosa, fortimuscula and barringtonensis Zones), and the earliy Visean (Vla) age suggested by the conodonts (Jenkins, 1974), has been partly resolved by Crane (1975, unpubl.), who has shown that the conodonts associated with the barringtonensis Zone are no older than cuIII y (V3b) and probably no younger than early Namurian (EI). However, there still remains the problem that the upper limit of the upper part of the australis Zone, as based on the Trevallyn ammonoids (Brown et al., 1965), is the same age as of younger (cuII y/cuIII y = V3b y/ÃŸ) than the upper limit of the upper sibzone (Gigantoproductus tenuirugosus Subzone) of a younger aspinosa Zone, as based on forminifera (Mamet's zones 13 to 15; V2b-V3b). Goniatite (Campbell, 1962) and conodont evidence (Crane, 1975, unpubl.) suggest that the base of the Levipustula levis Zone on the correlation chart of Jones et al. (1973) should be lowered to almost meet the barringtonensis Zone in the earliest Namurian (E1). Apart from brachiopod evidence there is no reliable information available to date the top of the L. levis Zone, and at present it is accepted that it extends into the Westphalian (Roberts, 1976). More biostratigraphical studies of brachiopods, ammonoids, conodonts, foraminifera, and other fossil groups from the Carboniferous of eastern Australia are needed, and an integration of the results of such studies is necessary in order to resolve many of the problems of correlation.

GSWA East Yilgarn Doserate 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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This GSWA East Yilgarn Doserate Grid Geodetic has a cell size of 0.00083 degrees (approximately 86m) and shows the terrestrial dose rate of the East Yilgarn, WA, 2005. The data used to produce this grid was acquired in 2005 by the WA Government, and consisted of 164506 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Comparison of the wet troposphere variations estimated from VLBI and WVR

The wet troposphere instability is used to be serve as one of the major
contributors to the total error budget of the VLBI group delay.
The least squares collocation method (LSCM) is designed to estimate the
wet troposphere delay for each observational epoch with sufficient precision.
The LSCM is incorporated into the OCCAM software for routine reduction of
the geodetic VLBI data. This paper presents a comparison of the wet 
troposphere delay estimates obtained with OCCAM and the Water Vapour 
Radiometer (WVR) data from VLBI station Onsala during the CONT'11 campaign.

Evaluation of the undiscovered hydrocarbon resources of the Bowen and Surat Basins, southern Queensland

Undiscovered hydrocarbon resources of the Bowen and Surat Basins in southern Queensland have been evaluated, on the basis of data compiled by the NGMA project Sedimentary Basins of Eastern Australia, including regional-scale seismic horizon and isopach maps and an extensive geochemical database of petroleum and potential source-rock samples. Estimates of the yields of hydrocarbons, calculated using the geochemical material balance method, are of very significant magnitude for both oil and gas. Although six principal source-rock intervals are recognised, over two-thirds of the oil is sourced from the Late Permian Baralaba interval. For gas, the Permian Buffel-Banana source unit contributes 31.5%, a significantly greater proportion than its oil counterpart, although, again, the Baralaba source unit is the most prodigious interval, yielding 40% of the total gas. A break-down of the yield in terms of major periods reveals that the Cretaceous to present-day window is by far the most important for both oil and gas generation, with 94.6% and 91.4 % of the respective totals. Thus, late structuring is more important for trap integrity than earlier structuring. By demonstrating that large quantities of hydrocarbons are potentially available for entrapment, the yield analysis should act as a stimulus to exploration initiatives, particularly in the search for stratigraphic traps.

Raw multibeam backscatter data of the Lord Howe Rise

Geoscience Australia carried out a marine survey on Lord Howe Island shelf (NSW) in 2008 (SS06_2008) to map seabed bathymetry and characterise benthic environments through colocated sampling of surface sediments and infauna, rock coring, observation of benthic habitats using underwater towed video, and measurement of ocean tides and wave generated currents. Subbottom profile data was also collected to map sediment thickness and shelf stratigraphy. Data and samples were acquired using the National Facility Research Vessel Southern Surveyor. Bathymetric data from this survey was merged with other preexisting bathymetric data (including LADS) to generate a grid covering 1034 sq km. As part of a separate Geoscience Australia survey in 2007 (TAN0713), an oceanographic mooring was deployed on the northern edge of Lord Howe Island shelf. The mooring was recovered during the 2008 survey following a 6 month deployment.
The "2461_ss062008" folder  contains raw multibeam backscatter data of the Lord Howe Rise. The raw multibeam backscatter data were collected along survey lines using SIMRAD EM300 from aboard RV Southern Surveyor

GSWA Widgiemooltha South 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 GSWA Widgiemooltha South TMI Grid Geodetic has a cell size of 0.00021 degrees (approximately 21m). The units are in nanoTesla (or nT).

Geoscience Australia conducted a seismic reflection survey in various localities throughout Tasmania between January and April 1995. This seismic survey formed part of AGSO project `TASGO' (b103201), a National Geoscience MappingAccord (NGMA) project carried out in conjunction with the Tasmanian Geological Survey (within Tasmania Development and Resources). The seismic survey obtained 134 km of 10 to 20 fold common mid-point (CMP) deep reflection seismic data along six traverses over an 8 week acquisition period. In addition, gravityobservations were made by the Tasmanian Geological Survey at 120 m intervals along five of the lines. Statewide aeromagnetic data has been interpolated to provide profiles along eachseismic line, and shot hole cuttings and water samples were taken for later analysis. The reflection crew provided support for AGSO's refraction and tomography data acquisition which is reported separately.
