Eucla East Gravity Complete Spherical Cap Bouguer Geodetic

Gravity data measure 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 Eucla East Gravity Complete Spherical Cap Bouguer Geodetic is a complete spherical cap Bouguer anomaly grid for the Eucla East Gravity Survey (P201164). This gravity survey was acquired under the project No. 201164 for the geological survey of WA. The grid has a cell size of 0.005 degrees (approximately 516m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 5202 gravity stations were acquired to produce this grid.

East Yilgarn, WA, 2005 (P1097), 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 East Yilgarn, WA, 2005 survey were acquired in 2005 by the WA Government, and consisted of 164506 line-kilometres of data at 400m line spacing and 60m 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.

Radioactive surveying from a helicopter

In connection with the use of airborne equipment for the detection of deposits of radio-active minerals, the Bureau has successfully used a DC.3 aircraft for the rapid coverage of large areas. It has been frequently suggested that a helicopter would have the following advantages over a conventional aircraft: (i) It can fly safely at lower heights and slower speeds than an ordinary aircraft, thus obtaining greater sensitivity from the detecting apparatus; (ii) It can be used effectively and safely in mountainous areas, in which low flying by a conventional aircraft would be impossible; (iii) It would enable the observer to locate exactly and identify from the air any small area on the ground showing radio-activity. In order to assess the performance of helicopters, a programme of test helicopter-mounted equipment over selected areas in New South Wales was carried out during March, 1953. The areas selected were: (i) Carcoar. This is a hilly area, but not timbered; (ii) Wunglebung, near Tenterfield. This is a mountainous, heavily timbered area; (iii) Broken Hill. This is a relatively flat featureless area; (iv) A test run was also made over Plen's deposit at Toongi,  near Dubbo, in order to obtain and check on the sensitivity of the detecting instrument. The survey techniques used and the results obtained in the several areas are discussed in detail below.

Conodonts from the Fairfield Group, Canning Basin, Western Australia

Conodonts from the Fairfield Group, Canning Basin were examined in order to determine both the sequence of species and the age of the Group. This work is part of a larger study of the latest Devonian and Early Carboniferous rocks exposed on the northern margin of the basin. A total of 57 form species referable to 21 form genera and an additional two multi-element taxa are described: two multi-element species, lcriodus platys and Pelekysgnathus australis, and one form species, Spathognathodus canningensis, are new and one form species, Hibbardella helmsi, has a new name. One multi-element taxon and fourteen form species are left in open nomenclature. Six assemblage zones are recognised although the endemic nature of the fauna and differing ranges of form species from those recorded elsewhere preclude accurate correlation with other sequences in Australia and overseas. However, a broad correlation is presented. The two lowest assemblage zones are latest Devonian and are present in the Gumhole Formation and the lowermost part of the Yellow Drum Sandstone. The upper four assemblage zones are Early Carboniferous (Tournaisian) and are present in the remainder of the Yellow Drum Sandstone and the Laurel Formation.

GSQ Walsh Red River thorium grid geodetic

This GSQ Walsh Red River thorium grid geodetic is an airborne-derived radiometric thorium window countrate grid for the Walsh, Red River, Qld, 1992/93 survey. 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 thorium (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.
This GSQ Walsh Red River thorium grid geodetic has a cell size of 0.00083 degrees (approximately 90m). The data are in units of counts per second (or cps). The data used to produce this grid was acquired in 1992 by the QLD Government, and consisted of 54145 line-kilometres of data at 400m line spacing and 100m terrain clearance.

AUSGeoid98 v.1.0 data files: Warwick (sh56-02)

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.

Seafloor environments of the northern Lord Howe Rise, Eastern Australia: Organic carbon and nitrogen concentrations and isotopes in seabed sediments.

Geoscience Australia marine reconnaissance survey TAN0713 to the Lord Howe Rise offshore eastern Australia was completed as part of the Federal Government's Offshore Energy Security Program between 7 October and 22 November 2007 using the New Zealand Government's research vessel Tangaroa. The survey was designed to sample key, deep-sea environments on the east Australian margin (a relatively poorly-studied shelf region in terms of sedimentology and benthic habitats) to better define the Capel and Faust basins, which are two major sedimentary basins beneath the Lord Howe Rise. Samples recovered on the survey contribute to a better understanding of the geology of the basins and assist with an appraisal of their petroleum potential. They also add to the inventory of baseline data on deep-sea sediments in Australia. The principal scientific objectives of the survey were to: (1) characterise the physical properties of the seabed associated with the Capel and Faust basins and Gifford Guyot; (2) investigate the geological history of the Capel and Faust basins from a geophysical and geological perspective; and (3) characterise the abiotic and biotic relationships on an offshore submerged plateau, a seamount, and locations where fluid escape features were evident. This dataset comprises organic carbon and nitrogen concentrations and isotopes in the upper 2 cm of seabed sediments.
Some relevant publications which pertain to these datasets include:

Bynoe Harbour Habitat Mapping Survey 2016: High resolution backscatter grid

This resource contains multibeam backscatter data for Bynoe Harbour collected by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Northern Territory Government (Department of Environment and Natural Resources) during the period between 3 and 27 May 2016 on the RV Solander (survey SOL6187/GA0351). This project was made possible through offset funds provided by INPEX-led Ichthys LNG Project to Northern Territory Government Department of Environment and Natural Resources, and co-investment from Geoscience Australia and Australian Institute of Marine Science. The intent of this four year (2014-2018) program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps that underpin marine resource management decisions. 
The specific objectives of the survey were to: 
1. Obtain high resolution geophysical (bathymetry) data for Bynoe Harbour; 
2. Characterise substrates (acoustic backscatter properties, grainsize, sediment chemistry) for Bynoe Harbour; and 
3. Collect tidal data for the survey area. Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; physical samples of seabed sediments, underwater photography and video of grab sample locations and oceanographic information including tidal data and sound velocity profiles. 
This dataset comprises multibeam backscatter data. A detailed account of the survey is provided in: Siwabessy, P.J.W., Smit, N., Atkinson, I., Dando, N., Harries, S., Howard, F.J.F., Li, J., Nicholas W.A., Picard, K., Radke, L.C., Tran, M., Williams, D. and Whiteway, T. 2016.
