AUSGeoid98 v.1.0 data files:  (sl51-09)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

Honeysuckle Creek tmi rtp 1vd 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 Honeysuckle Creek tmi rtp 1vd grid geodetic is the first vertical derivative of the TMI RTP grid of the SMMSP - MagSpec - Honeysuckle Creek, Vic, 2001 survey.
This grid has a cell size of 0.00021 degrees (approximately 21m) , and given in units of nT per metre (nT/m).  The data used to produce the TMI grid was acquired in 2001 by the VIC Government, and consisted of 14795 line-kilometres of data at 100m line spacing and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey. A first vertical derivative was calculated by applying a fast Fourier transform (FFT) process to the TMI RTP grid of the SMMSP - MagSpec - Honeysuckle Creek, Vic, 2001 survey to produce this grid. This grid was calculated using an algorithm from the INTREPID Geophysics software package. This grid shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The grid can also be used to locate structural features such as dykes.

Understanding the Architecture and Petroleum Potential of Australia's Onshore Sedimentary Basins with Deep Seismic Reflection Data

The Onshore Energy Security Program, funded by the Australian Government and conducted by Geoscience Australia, has acquired deep seismic reflection data across several frontier sedimentary basins to stimulate petroleum exploration in onshore Australia. Interpretation of the new seismic data from these onshore basins, focusing on overall basin geometry, internal sequence stratigraphy and petroleum potential, will be presented here.
At the southern end of the exposed part of the Mt Isa Province, northwest Queensland, a deep seismic line (06GA-M6) crossed the Burke River Structural Zone of the Georgina Basin. The basin here is &gt;50 km wide, with a half graben geometry, bounded in the west by a rift border fault. 
The Millungera Basin in northwest Queensland is completely covered by the Eromanga-Carpentaria Basin and was unknown prior to relatively short segments across the western part of the basin being imaged seismically in two lines (06GA-M4 and 06GA-M5) in 2006. Following this, seismic line 07GA-IG1 imaged a 65 km wide section of the basin. The geometry of internal stratigraphic sequences and a post-depositional thrust margin indicate that the original succession was much thicker than preserved today and there is potential for a petroleum system to exist.
The Yathong Trough, in the southeast part of the Darling Basin in NSW, has been imaged in seismic line 08GA-RS2, with several stratigraphic sequences being mapped. Previous studies indicate that the upper part of this basin consists of Devonian sedimentary rocks, with potential source rocks at depth.
In eastern South Australia, seismic line 08GA-A1 crossed the Cambrian Arrowie Basin, which is underlain by a Neoproterozoic succession of the Adelaide Rift System. Shallow drillholes have aided the assessment of the petroleum potential of the Cambrian Hawker Group, which contains bitumen in some of the cores, indicating the presence of source rocks in the basin system.

2009 Mount Stromlo SLR Observatory Local Survey

The integrity and strength of multi-technique terrestrial reference frames, such as realisations of the International Terrestrial Reference Frame (ITRF), depend on the precisely measured and expressed local-tie connections between space geodetic observing systems at co-located observatories.  Australia has several observatories which together host the full variety of space geodetic observation techniques, including Global Navigation Satellites Systems (GNSS), Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR) and Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) beacons.
This report documents the technical aspects of the survey undertaken to determine the local-tie connections at the Mount Stromlo SLR Observatory.  The Mount Stromlo laser ranging observatory is located next the Australian National University (ANU) Research School of Astronomy and Astrophysics on Mount Stromlo in Canberra.  The observatory has a Satellite Laser Ranging (SLR) telescope co-located with three permanent GNSS sites, two of which contribute to the International GNSS Service (IGS) network.  Nearby there is a national gravity observatory at the ANU school and a radio telescope used for Very Long Baseline Interferometry (VLBI) at the Canberra Deep Space Communication Complex (CDSCC) which is operated by NASA.  The survey was conducted in November 2009 by surveyors from Geoscience Australia.  Precision classical geodetic observations were combined with geodetic GNSS observations to determine the repeat relationship between the SLR system invariant point (IVP) and the conventional reference points of the GNSS antennas and the surrounding survey control.
The results of this survey have been provided to the International Earth Rotation Service (IERS) for inclusion in the next realisation of the ITRF.

The Design of Radar Corner Reflectors for the Australian Geophysical Observing System : A single design suitable for InSAR deformation monitoring and SAR calibration at multiple microwave frequency bands

As part of the AuScope Australian Geophysical Observing System initiative, Geoscience Australia constructed a new regional-scale geodetic network that includes an array of radar corner reflectors. The purpose of the new geodetic network is to monitor crustal deformation by combining spatially dense but temporally sparse deformation maps derived from the Interferometric Synthetic Aperture Radar (InSAR) technique and temporally dense but spatially sparse point measurements from Global Navigation Satellite System (GNSS) networks. The radar corner reflector array is also designed to support calibration and validation of Synthetic Aperture Radar (SAR) products from orbiting satellites. This GA Record outlines the prototyping exercises undertaken to determine the most appropriate design of radar corner reflector that can exploit SAR acquisitions at X-, C- and L-band radar frequencies. A set of 18 corner reflector prototypes were manufactured that had different sizes and plate finishes. These prototypes had their radar signatures characterised in experiments conducted at the Defence Science and Technology Organisation ground radar reflection range in St Kilda, South Australia. Following this, the prototypes were temporarily deployed between December 2013 and May 2014 at a grazing property in Gunning, New South Wales. During this deployment the radar response of the corner reflectors was tested in SAR images from the TerraSAR-X, COSMO-SkyMed, RADARSAT-2 and RISAT-1 satellites. As a result of these experiments, a triangular trihedral corner reflector design with an inner leg dimension of 1.5 metres and powder-coated plate finish was chosen for permanent deployment in the new array. Fifteen of the prototypes and 25 new 1.5 metre corner reflectors were fully installed in the new array in the northern Surat Basin, Queensland, by 21 November 2014.

New U–Pb geochronology for the South Nicholson region and implications for stratigraphic correlations

The South Nicholson Basin sits between the Mount Isa Province to the east and southern McArthur Basin to the northwest. The McArthur Basin and Mount Isa Province are well studied and highly prospective for both mineral and energy resources. In contrast, the South Nicholson region is mostly undercover, little studied and consequently relatively poorly understood. A comprehensive U–Pb SHRIMP zircon and xenotime geochronology program was undertaken to better understand the stratigraphy of the South Nicholson region and its relationship to the more overtly prospective adjacent Mount Isa Province and McArthur Basin. The age data indicate South Nicholson Basin deposition commenced ca 1483 Ma, with cessation at least by ca 1266 Ma. The latter age, based on U–Pb xenotime, is currently interpreted as the timing of post-diagenetic regional fluid flow. The geochronology presented here provides the first direct age data confirming the South Nicholson Group is broadly contemporaneous with the Roper Group of the McArthur Basin. Some rocks, mapped previously as Mesoproterozoic South Nicholson Group and comprised of proximal, immature lithofacies, have detrital spectra consistent with that of the late Paleoproterozoic McNamara Group of the western Mount Isa Province which necessitates a revision of existing regional stratigraphic relationships. The stratigraphic revisions and correlations proposed here significantly expands the extent of highly prospective late Paleoproterozoic stratigraphy across the South Nicholson region and possibly, further west beneath the Georgina Basin. The data and conclusions presented here allow for improved regional stratigraphic correlations between Proterozoic basins, improved commodity prospectivity and targeted exploration strategies across central northern Australia.
