Wilsons Promontory SRL - West Glennie & Refuge Cove Survey 2016 (GA4882)

The Wilsons Promontory West Glennie and Refuge Cove bathymetry survey was acquired by Deakin University Marine Mapping lab onboard the M/V Yolla on 18 June 2016 using a Kongsberg EM2040c. This survey was part of a Parks Victoria project to assess the impact of the Wilsons Promontory Marine National Park on southern rock lobster populations. These data were collected to provide habitat information in the sampling locations outside the park where no multibeam data existed. The survey was led by Dr. Daniel Ierodiaconou (Deakin University). This dataset contains a 2m-resolution 32-bit floating point GeoTIFF file of the bathymetry in the study area, derived from the processed EM2040C bathymetry data, using CARIS HIPS and SIPS software. A detailed report on the survey is provided in: Young M, Porskamp P, Murfitt S, Wines S, Tinkler P, Bursic, J., Allan B, Howe S, Whitmarsh S, Pocklington J, Ierodiaconou D 2022.

Maximising efficiencies in CCS projects through produced brine use in Australia

Internationally, the number of carbon capture and storage (CCS) projects has been increasing with more than 61 new CCS facilities added to operations around the globe in 2022, including six projects in Australia (GCCSI, 2022). The extraction of reservoir fluid will be an essential component of the CCS workflow for some of projects in order to manage reservoir pressure variations and optimise the subsurface storage space. While we refer to reservoir fluid as brine throughout this paper for simplicity, reservoir fluids can range from brackish to more saline (briny) water. Brine management requires early planning, as it has implications for the project design and cost, and can even unlock new geological storage space in optimal locations. Beneficial use and disposal options for brine produced as a result of carbon dioxide (CO2) storage has been considered at a regional or national scale around the world, but not yet in Australia. For example, it may be possible to harvest energy, water, and mineral resources from extracted brine. Here, we consider how experiences in brine management across other Australian industries can be transferred to domestic CCS projects.

Australian Diamond Exploration 2006: Where are the Greenfields?

Paper presented at the World Diamond Conference held in Perth, 20-21 November, 2006.
The paper gives an overview of current diamond exploration and discovery in Australia and reviews the state of knowledge of the geological setting and controls on known diamondiferous intrusions in Australia as an important indicator of Australia's diamond potential. Reduced levels of spending in recent years has been associated with a contraction of exploration largely to brownfields regions. Exceptions are the discovery of the diamondiferous Blacktop kimberlite in the West Pilbara region and, to a lesser extent, new kimberlites discovered in the eastern Gawler Craton.
Most Australian kimberlites and lamproites, like those elsewhere, show evidence of strong structural controls. These features are commonly evident in continental scale geophysical datasets. Many of the diamondiferous intrusions lie at major boundaries/discontinuities evident in seismic S-wave tomographic models and at discontinuities evident in multi-scale analysis of horizontal gradients of continental magnetic anomaly and gravity datasets (Jaques and Milligan, 2004: Lithos 77, 783-802). These relationships are predicted by modelling with numerical mantle convection code which indicates that abrupt changes in lithospheric thickness focus lithospheric stress gradients affecting melt migration and accumulation thereby making the mantle beneath the margins of stable cratons favourable sites for kimberlite generation (O'Neill, Moresi and Jaques, Tectonophysics 404, 217-236).
Diamond potential is intimately linked to craton evolution. Eclogitic diamond suites appear to be linked to subduction events at craton margins. Continental-scale geophysics can help define fertile source regions (mantle roots) and identify favourable tectonic zones/corridors. Improved targeting is required to better identify greenfields provinces which have the potential to host new diamond pipes. Such targeting would be enhanced by improved seismic tomographic models of the Australian lithosphere and through a better understanding of geodynamic evolution of the Australian continent.

Oceanic Shoals Commonwealth Marine Reserve - High Resolution Multibeam Acoustic Backscatter Grids

This resource contains bathymetry and backscatter 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 (survey GA0339/SOL5650). The survey used a Kongsberg EM3002 300 kHz multibeam sonar system mounted in single head configuration to map four areas, covering a combined area of 507 square kilometres. Data are gridded to 2 m spatial resolution. 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 et al. 2013).

Simpson Extensions - Andado, NT, 2004 (P1061), radiometric line data, AWAGS levelled

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.
 This Simpson Extensions - Andado, NT, 2004 (P1061), radiometric line data, AWAGS levelled were acquired in 2004 by the NT Government, and consisted of 34000 line-kilometres of data at a line spacing between 200m and 400m, 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.

Preliminary report on the geology of the Fitzroy Basin, Kimberley Division, Western Australia. June 1953

The investigation of the Fitzroy Basin and adjacent areas was commenced in 1948 when a detailed survey was made of the Nerrima Structure and a widespread reconnaissance by land, sea and air was completed. The Fitzroy Basin survey was completed in 1952 and during this period 24 months were spent in the field and the remainder in office preparation. Approximately 40,000 square miles were examined during the survey and detailed maps covering an area of 28,000 square miles have been prepared at 1 inch = 1 miles, 1 inch = 2 miles and 1 inch = 10 miles. The area has been examined in the past in varying detail by three geological parties on behalf of local and overseas oil companies. The purpose of this survey was to examine the complete sedimentary sequence in sufficient detail to solve the problems encountered by previous surveys and eventually to be in a position to assess to a reliable degree the petroleum prospects of the area based on the examination of surface outcrop. The assessment of the petroleum prospects of the area has very definite limitations in that the potential source rocks (Devonian and Ordovician) are limited to the extreme eastern margin of the basin and nothing is known about their distribution or facies elsewhere under the cover of Permian and Mesozoic sediments. The aerial photography of the area, which was conducted by the Survey Squadron of the Royal Australian Air Force, has been the basis of all mapping, as reliable topographic maps of the area were not available.

Report on seismic refraction traverse at Comet, Queensland, (1951)

Towards the end of 1950, the deep bore which the Shell Development Company was drilling to test for oil on the Morella structure, 35 miles south of Rolleston, entered andesite at approximately 4000 ft. After boring about 200 ft into the andesite, the Company decided to abandon the hole. A new site for a test bore was selected on the Comet anticlinal structure, 60 miles north of Rolleston. Before proceeding with this new test, evidence was needed to ensure that neither a shallow basement nor volcanic rocks existed under this structure. The Bureau was therefore asked to shoot a refraction traverse over the anticline, in order to determine if basement rocks were likely to be present at a shallow depth. As a result the Bureau sent a seismic party to the area during January 1951. Fairly definite evidence was obtained of basement velocities occurring at a depth of less than 3000 ft, and after discussions, a decision was made not to proceed with the drilling of the Comet structure. The results have now been investigated in detail and are presented in this report.

Elkedra 5, NT, 1999 (P1006), 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 Elkedra, NT, 1999 survey were acquired in 1999 by the NT Government, and consisted of 121182 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Northern Territory Bitumen Strandings Progress: Report no. 1

The discovery of bitumen on beaches and rocky points between Bathurst Island and Elcho Island dates back to at least 1922 when a Reverend Jennison found a deposit on a beach near Elcho Island Mission. This was later described by Arthur Wade in 1924 as "flat cakes filling lenticular cavities on the flaggy beds".
These have since been again recorded several times between 1965 and 1984.
Some people think the bitumen near the old mission is in situ whereas others have seen bitumen draped all over the wave cut platform at low tide all along the island.
