  • This resource includes bathymetry data acquired during the Southern Gulf of Carpentaria bathymetry survey using Simrad EM300 and Reson Seabat 8101 multibeam sonar systems. Southern Gulf of Carpentaria bathymetry survey (GA0276) was led by Dr. Peter Harris (Geoscience Australia) aboard the Marine National Facility's research vessel Southern Surveyor, from the 23rd of March to the 13th of April 2005. The primary objective of the expedition was to map submerged reefs to ascertain their geomorphic nature and document the benthic communities and fauna. This dataset contains four 4m to 7m resolution 32-bit floating point geotiff files of the bathymetry in five study areas and transits, derived from the processed EM300 and Reson 8101 bathymetry data, using CARIS HIPS and SIPS software. A detailed report on the survey is provided in: Harris, P et al. 2006.

  • The Oaklands-Coorabin Coalfield in the Riverina Division of New South Wales has been known for many years. Seismic refraction tests were carried out on a number of sections to assist in the interpretation of the gravity results during July and Sepetember, 1949.

  • The Bureau of Mineral Resources made an experimental seismic survey in the Otway Basin, Victoria and SA, and in the Sydney Basin, NSW, from April to November 1965 and from mid February to mid March 1966. The survey used explosives as an energy source to obtain seismic reflection data for comparison with the results from an experimental 'Vibroseis' survey carried out for the Bureau by Seismograph Service Ltd during 1964.

  • Some experimental geophysical work was undertaken by the Bureau of Mineral Resources at the Moura Coalfield in Queensland in order to investigate the structure of coal seams which lie within 1000 feet of the surface. The aim of the survey was to evaluate the use of geophysical techniques for locating faults of small displacement. Most of the effort was concentrated on shallow seismic reflection techniques but additional techniques (magnetic, gravity, resistivity, electromagnetic and induced polarization) were used. The whole area of the survey was covered with a close-spaced grid of gravity and magnetic stations. A lesser effort was devoted to resistivity, electromagnetic, and induced polarization methods, the object being to take advantage of the opportunity to tryout these relatively inexpensive methods in the hope that they might give some indications of fault locations. These methods will be evaluated in a separate Record; this one deals- with the results of the seismic work. Encouraging results were obtained from seismic reflection work. The uppermost economic coal seam was mapped to within 300 feet of the surface and areas of faulting could be deduced from time differences and lack of continuity in reflections.

  • A hybrid high-resolution seismic survey was undertaken adjacent to the Eurabba State Forest near Quandialla, Western NSW between June 29 and July 3 2003 acquiring both refraction and reflection data. The Australian National Seismic Imaging Resource (ANSIR) carried out the field work in conjunction with University of Canberra and Dryland Salinity Hazard Mitigation Program (DSHMP) research staff and students. Processing of the acquired refraction information was performed with the assistance of ANSIR staff. This survey was designed to collect and compare a shallow, high-resolution seismic dataset against nearby regional scale seismic datasets and other complementary sources of spatial information including NanoTEM, drill hole data, satellite imagery and regolith-landform mapping. The multi-disciplinary approach is designed for imaging shallow sedimentary structures and determining depth to bedrock. The combined aim of utilizing the multidisciplinary approach is to understand shallow fluid flow within the Booberoi-Quandialla Transect area and how this relates to observed outbreaks of dryland salinity. These observations will aid in the development of a shallow fluid flow model for the Bland catchment, especially over the Booberoi- Quandialla Transect area.

  • The Tanami region of the Northern Territory is a major Australian gold province and contains the world class Callie gold deposit. Shallow sediments largely obscure basement host rock, so the application of geophysical techniques has become an important mapping tool for the further exploration and development of the mine. Acquisition of seismic data along a single line across the deposit will test the understanding of key structures, some of which are related to mineralisation. By extending the line beyond the boundaries of the currently well understood mine area, we hope to illuminate continuations of stratigraphic and structural trends. These structures include: fault geometries, relationships of stratigraphic packages to controlling structures and stratigraphic thickness. The survey is designed to provide data to image to approximately 2km depth. Integration the data from this project with that of the Tanami Seismic Reflection Acquisition Project will provide a broader understanding of the structural and stratigraphic frame work of both the mine area and the Tanami region.

  • <p>Geoscience Australia conducted a seismic survey in the central Eromanga Basin in Queensland from July to Late November 1982. This survey was a continuation of the work undertaken in 1980 and 1981 to investigate the structure, stratigraphy, geological and tectonic evolution, and petroleum potential of the area. The survey obtained 485 km of six-fold Common-Depth-Point reflection data, in the Adavale Basin, Cooladdi Trough and Pleasant Creek Arch areas.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74970</b>

  • <p>Geoscience Australia conducted a seismic survey in the central Eromanga Basin in Queensland in 1981. This survey was a continuation of the work undertaken in 1980 to investigate the structure, stratigraphy, geological and tectonic evolution, and petroleum potential of the area. The survey obtained 438 km of six-fold Common-Depth-Point seismic reflection data, in the Quilpie Trough and over the Cooper and Thomson Synclines.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74971</b>

  • Trace Energy Services was contracted by the Australian National Seismic Imaging Resource (ANSIR) to conduct the WA seismic 2004 survey in the eastern & northern Goldfields region of Western Australia. There were 148.59 km of 2D seismic reflection data recorded, 137.54 km over 29 traverses using Litton 315 Paystars and 11.05 km over 5 traverses using a single IVI Minivib as source. All lines were situated within the lease boundaries of gold mining companies, namely, Sons of Gwalia (Tarmoola & Gwalia) (L165), Placer Dome (Kanowna Belle, Wallaby, Granny Smith, Lancefield & Mt Morgans) (L166), Anglo Gold (Sunrise Dam) (L167) and Goldfields (St Ives at Kambalda) (L168). <b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74862</b>
