The Bureau of Mineral Resources, Geology and Geophysics (BMR) did a reconnaissance seismic survey in the central portion of the Bowen Basin in November, 1960. The objectives of the survey were to determine the structure of the Basin and the thickness of sediments by traversing from the western margin of the Basin near Anakie to the eastern margin east of Duaringa. Two other seismic surveys conducted in this Bowen Basin are Cooroorah Anticline seismic survey in 1959 (survey L037) and 254km seismic survey near the towns of Duaringa and Blackwater (survey L129).

Processed Stacked and Migrated SEG-Y seismic data and section images for the Youanmi Deep Crustal Seismic Survey. This survey was conducted under a National Geoscience Agreement with the Western Australia Geological Survey. Funding was through the Onshore Energy Security Program and Western Australia's Exploration Incentive Scheme. The objective of the survey was to image the northwest Yilgarn Craton to the Ida Fault crossing the Meekatharra structural zone, a focus of gold mineralization. Data are supplied as SEG-Y files, TIFF and PDF images. Raw data for this survey are available on request from clientservices@ga.gov.au

We report four lessons from experience gained in applying the multiple-mode spatially-averaged coherency method (MMSPAC) at 25 sites in Newcastle (NSW) for the purpose of establishing shear-wave velocity profiles as part of an earthquake hazard study. The MMSPAC technique is logistically viable for use in urban and suburban areas, both on grass sports fields and parks, and on footpaths and roads. A set of seven earthquake-type recording systems and team of three personnel is sufficient to survey three sites per day. The uncertainties of local noise sources from adjacent road traffic or from service pipes contribute to loss of low-frequency SPAC data in a way which is difficult to predict in survey design. Coherencies between individual pairs of sensors should be studied as a quality-control measure with a view to excluding noise-affected sensors prior to interpretation; useful data can still be obtained at a site where one sensor is excluded. The combined use of both SPAC data and HVSR data in inversion and interpretation is a requirement in order to make effective use of low frequency data (typically 0.5 to 2 Hz at these sites) and thus resolve shear-wave velocities in basement rock below 20 to 50 m of soft transported sediments.

The 2005 Broken Hill High Resolution 2D Seismic Survey, contracted to Terrex Seismic Pty Ltd for ANSIR (Australian National Seismic Imaging Resource) and New South Wales Department of Primary Industries - Mineral Resources. The survey operation was located approximately 6km north east of the town of Broken Hill in western New South Wales. The high resolution 120 fold seismic reflection survey was carried out in August 2005 along a 12 km portion of the seismic line 96AGS-BH1B in the Broken Hill region that was recorded by the Australian Geological Survey Organisation (AGSO) in 1996-97. The purpose of the new survey was to compare high resolution seismic data with low fold explosive seismic data along the same line and to image geological structures at shallow crustal levels. Two HEMI-60 Vibroseis trucks were used as sources. A total of 12.2 km of 120 fold seismic reflection data were acquired to 16 s TWT, except for the last 2 km of the profile where the fold was decreased to 60.

Terracorp under its facilities management agreement with ANSIR was contracted to conduct the 1999 Yilgarn Seismic Survey located in the Kalgoorlie Goldfields region of Western Australia. In total 194.64 kms of 60 and 120 fold, 240 channel data was recorded between 19th August and 3rd September 1999. This high resolution and regional seismic profiles were acquired in order to image the major structural features of the region, particularly the highly mineralised Bardoc-Boorara Shear and to provide three-dimensional information about the relationship between the greenstones and the granites.

Terracorp under its facilities management agreement with ANSIR was contracted to conduct the 1999 Lachlan and Marsden Seismic Surveys located around West Wyalong, NSW. In total 206.47 kms of 60, 80 and 120 fold, 160 & 240 channel data was recorded between 11th September 1999 and 29th September 1999. This Eastern Lachlan Orogen project was part of the research conducted by the Australian Geodynamics Cooperative Research Centre (AGCRC), which was established under the auspices of the Commonwealth Government's Cooperative Research Centres Program in 1993. The Ordovician volcanics and associated rocks of the Eastern Lachlan Orogen are important as a significant Australian gold province. To assist mineral exploration companies in understanding the geodynamics and mineral systems of this region, the AGCRC has been collecting information that will assist in the development of geodynamic and exploration models of the region. To understand the size and architecture of the mineral system, we need to know the threedimensional geometry of the system we are dealing with. To start to address this, in 1997 the AGCRC commenced a project in the Eastern Lachlan Orogen by collecting seismic information to examine the regional scale crustal architecture as a first step towards building exploration models for the region. We continued this work in 1999 with the collection of further deep seismic reflection data along two traverses in the Forbes-West Wyalong region. The northern traverse was jointly funded by the AGCRC and the Geological Survey of New South Wales (GSNSW) as a cooperative research project. The southern traverse was funded by the AGCRC, and co-investigators in the seismic interpretation involved staff from the AGCRC at AGSO, the GSNSW, and AGSO's Gilmore Project.

<p>Geoscience Australia conducted a seismic reflection survey in various localities throughout Tasmania between January and April 1995. This seismic survey formed part of AGSO project `TASGO' (b103201), a National Geoscience MappingAccord (NGMA) project carried out in conjunction with the Tasmanian Geological Survey (within Tasmania Development and Resources). The seismic survey obtained 134 km of 10 to 20 fold common mid-point (CMP) deep reflection seismic data along six traverses over an 8 week acquisition period. In addition, gravityobservations were made by the Tasmanian Geological Survey at 120 m intervals along five of the lines. Statewide aeromagnetic data has been interpolated to provide profiles along eachseismic line, and shot hole cuttings and water samples were taken for later analysis. The reflection crew provided support for AGSO's refraction and tomography data acquisition which is reported separately.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74942</b>

<p>Geoscience Australia conducted a deep seismic reflection test survey in the onshore portion of the Otway Basin in the southeastern part of South Australia and southwestern part of Victoria, from late October to early November 1991. The seismic test survey was undertaken to test the feasibility of recording deep seismic reflection data prior to commencing a major deep seismic reflection survey in the Otway Basin. A planned major deep seismic reflection survey by AGSO formed part of a National Geoscience Mapping Accord (NGMA) project to study the early development of the Otway Basin. The seismic reflection test survey operated for a period of three weeks, including mobilisation and demobilisation to the survey area, with five test sites occupied during the test survey. The seismic test sites were positioned to examine the feasibility of recording deep seismic reflections in areas with different outcropping rock types along the proposed main seismic lines. eMF seismic profiles were recorded along all five test lines, with uphole shoots, shot depth and charge size comparison tests performed at several of the sites. Good quality deep seismic reflection events were recorded at several of the seismic test sites. The seismic test survey was important in highlighting areas with difficult shothole drilling conditions, especially the palaeo-sand dunes along the SA-Victoria border, and the Tertiary shelly sands with shallow water table near Lake Bonney. A major seismic survey would require all shothole drilling rigs to be equipped with portable mudpits to enable shotholes to be drilled in the palaeo-sand dunes and shelly sands.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74948</b>
