Cobar, NSW, 1957 (P166), 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 Cobar, NSW, 1957 survey were acquired in 1957 by the NSW Government, and consisted of 10900 line-kilometres of data at 1600m line spacing and 150m 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.

Characterisation of radiogenic monoalkenes in Australian oils and condensate

Thirteen Australian oils and one condensate, covering oil reservoir ages from Mesoproterozoic to Early Cretaceous, show monoalkene contents varying from 0.01 to 22.3 wt% of the whole liquid. Radiolysis of saturated hydrocarbons is the most likely process leading to oils with high alkene contents. The major radiolytic component is an unresolved complex mixture (UCM). The bulk of the resolved alkene compounds are positional isomers of n-alkenes. Methyl branched and cyclohexyl alkenes are minor components. Internal n-alkene isomers have a trans configuration dominant over the cis isomer. The oil with the longest reservoir residence time shows the highest content of internal n-alkenes relative to terminal 1-alkenes as well as the highest trans/cis ratio, suggesting the extended time has resulted in rearrangement to near thermodynamic equilibrium of the congruent monoalkenes. The radiolytic monoalkenes in the Ordovician-reservoired oil with the highest alkene content is likely influenced by a higher probability of intermolecular interactions and different product pathways in a complex mixture. Here, the relative proportion of alkene mimics the relative abundance of n-alkanes, suggesting that radiolytic C–C bond cleavage is suppressed when the alkene/alkane ratio is elevated and that the preferred pathway of n-alkane radiolysis favours the production of terminal monoalkenes. Radiolysis of the alkane UCM together with crosslinking and branching of n-alkane-derived radiolysis products contribute to the higher relative proportion of the alkene UCM. The similar carbon and hydrogen isotopic ratios of the n-alkanes and n-alkenes supports a parent–daughter relationship.

Outer Darwin Harbour Marine Survey 2015: High resolution backscatter grid

This resource contains multibeam sonar backscatter data for Outer Darwin Harbour collected by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Northern Territory Government (Department of Land Resource Management) during the period from 28 May and 23 June 2015 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 Land Resource Management, 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:


Obtain high resolution geophysical (bathymetry) data for outer Darwin Harbour, including Shoal Bay;


Characterise substrates (acoustic backscatter properties, grainsize, sediment chemistry) for outer Darwin Harbour, including Shoal Bay; and


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.

GSWA South Canning 2 Morris Cobb 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 South Canning 2 Morris Cobb Doserate Grid Geodetic has a cell size of 0.00083 degrees (approximately 88m) and shows the terrestrial dose rate of the Morris-Cobb, WA, 2010 (South Canning 2). The data used to produce this grid was acquired in 2010 by the WA Government, and consisted of 134843 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Inter-disciplinary, multi-physics, multi-scale approaches for groundwater system investigations and hydrogeological assessments in Northern Australia: The Exploring for the Future Groundwater Program

The development of Northern Australia has been identified as an Australian national priority, with water availability being fundamental to economic development. Surface water options are limited hence identification of new groundwater resources and water banking options is essential. Over the past 4 years, Geoscience Australia, in concert with State and Territory partners, has been involved in groundwater investigations across northern Australia, including ‘frontier’ sedimentary basins and paleovalleys within priority infrastructure ‘fairways’, as well as national-scale investigations. 
New data acquisition has included multi-scale airborne electromagnetics surveys; LiDAR surveys; drilling; bore testing; ground geophysics (e.g. surface nuclear magnetic resonance, seismic reflection); borehole geophysics; hydrochemical and hydrodynamic analysis; age dating of water and landscape materials; and mapping (geomorphic, morphotectonic, regolith, geological and hydrological). The program also includes assessment of national to catchment scale water balance through use of satellite gravity, InSAR, GPS data and Digital Earth Australia products. 
A multi-physics, multi-scale, inter-disciplinary approach has been critical in enabling the rapid identification and assessment of significant new potential fresh groundwater resources and MAR options within tectonically inverted sedimentary basins in the Kimberley Region (Fitzroy Basin (WA)) and Bonaparte Basin (WA and NT); Western Davenport Wiso Basin (NT); and Southern Georgina Basin (NT). The program has also helped define: the extents of groundwater resources near Alice Springs (NT); aquifer compartmentalisation in the Daly Basin and at Howards East (NT); near-surface faults in the Surat and Galilee Basins; groundwater resources in 6 remote communities (NT); and groundwater resources in the Tennant Creek area, Ti Tree Basin; and more broadly across northern Australia in Cenozoic paleovalleys and Proterozoic, Paleozoic, Mesozoic and Tertiary sedimentary basins.
Project data and value-added products inform groundwater numerical modelling and hydrogeological assessments. Program outputs are being used to underpin water allocation planning and investment decisions in agriculture, community water supplies and regional industries.

Antarctic Geodesy Technical Report - Casey 2001

In October 2001, maintenance work on the GPS and ancillary equipment at Australia's Antarctic base at Casey was carried out. This site forms part of the Australian Regional GPS Network (ARGN). In addition accurate measurements were taken of the relationship between the ARGN monument and the three reference marks to check for any possible local movement since the site was established in December 1993. These measurements also provide a reliable base measurement for future monitoring. A GPS connection and difference in height by optical levelling between the ARGN monument and the tide gauge benchmark was also completed. This report documents the methods and results of these surveys.
