SA Exploration Initiative 1995 - Area B15 infill (P704), 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 SA Exploration Initiative 1995 - Area B15 survey were acquired in 1995 by the SA Government, and consisted of 27278 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.

AUSGeoid98 v.1.0 data files:  (sj52-08)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

Depth to Magnetic Basement of the Capel and Faust Basins, Lord Howe Rise

We have analysed the shipborne magnetic data interms of depth to magnetic basement and tried to find out the basement structure independently from the magnetic and reconcile with the seismic interpretation.  Our result indicates a possible depocentre at the northwest part of the study area, which is in agreement with the resimic result. The depocenter is about 6 km deep and extending NNW-ESE direction and the study also suggests the presence of a ridge at the centre of the study area and trending along N-S direction. The structures derived from the magnetic are broadly matching with the seismic results. So, the technique may be useful for delineating the sediment pocket inside the basin, thus help in shoring out the zone of interest inside the basin for further detail survey.

Yorke Peninsula (Moonta Subdomain) GIS Dataset

The Moonta Subdomain forms the southern part of the Olympic Cu-Au province on the eastern margin of the Gawler Craton, and underlies most of the Yorke Peninsula and Spencer Gulf.  The domain basement comprises metasediments and metavolcanics of the Palaeoproterozoic Wallaroo Group (~1760-1740 Ma) which were deformed and metamorphosed to upper greenschist-amphibolite facies during the Kimban Orogeny (~1720 Ma).  These rocks were further deformed and intruded by granitoids and minor mafic intrusions of the Hiltaba Suite between about 1600 Ma and 1575 Ma.
The Moonta Subdomain basement is highly prospective for iron oxide-Cu-Au mineralisation associated with the Hiltaba magmatic event.  However outcrop of these basement rocks is limited almost entirely to narrow coastal exposures.  The majority of the prospective basement is concealed by up to 100 metres of Neoproterozoic to Quaternary sediments, and geological mapping of the basement is largely limited to interpretation of geophysics (airborne magnetics, gravity, AEM) and drilling.

Australian - New Zealand Geodetic VLBI Network Project

Geodetic VLBI technique maintainces the International Celestial Reference Frame (ICRF) and contributes significantly to the International Terrestrial Reference Frame (ITRF) realization, Earth Orientation Parameter (EOP) service, etc. However, only Hobart (Tasmania) radio telescope is involved into geodetic VLBI observational program on regular basis in Australasia. Due to paucity of appropriate radio telescopes the ICRF and ITRF realizations have worse accuracy in the Southern Hemisphere. The project of geodetic Australian VLBI network has been developed as a part of the national geodetic network strategy.
New VLBI network will consist of three Australian and two New Zealand comparatively small (about 12 meter in diameter) fast slew rate dishes equipped with Mark5B recorders.
All VLBI sites will be collocated with permanent GPS receivers, and some of them
- with SLR facilities to enforce this network strength and verify the inter-technique
performance.
This network will work
- to improve the ITRF in Australia-South Pacific region;
- to improve the ICRF in the Southern Hemisphere;
- to contribute to geophysical researches (sea level change, Earth rotation irregularities);
- to monitor crustal deformation of the Australian continent as well as the New Zealand subduction zone

Oceanic Shoals Commonwealth Marine Reserve - Chlorin data from seabed sediments

This resource contains geochemistry data for the Oceanic Shoals Commonwealth Marine Reserve (CMR) in the Timor Sea collected by Geoscience Australia during September and October 2012 on RV Solander. This dataset comprises total chlorin concentrations and chlorin indices from seabed sediments (0-2 cm). The Oceanic Shoals Commonwealth Marine Reserve survey was undertaken as an activity within the Australian Government's National Environmental Research Program Marine Biodiversity Hub and was the key component of Research Theme 4 - Regional Biodiversity Discovery to Support Marine Bioregional Plans. Hub partners involved in the survey included the Australian Institute of Marine Science, Geoscience Australia, the University of Western Australia, Museum Victoria and the Museum and Art Gallery of the Northern Territory. Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; sub-bottom acoustic profiles; physical samples of seabed sediments, infauna and epibenthic biota; towed underwater video and still camera observations of seabed habitats; baited video observations of demersal and pelagic fish, and; oceanographic measurements of the water column from CTD (conductivity, temperature, depth) casts and from deployment of sea surface drifters. Further information on the survey is available in the post-survey report published as Geoscience Australia Record 2013/38: Nichol, S.L., Howard, F.J.F., Kool, J., Stowar, M., Bouchet, P., Radke, L.,Siwabessy, J., Przeslawski, R., Picard, K., Alvarez de Glasby, B., Colquhoun, J., Letessier, T. &amp; Heyward, A. 2013.
