  • The 2005 Tanami Seismic Survey was carried out from May to July for a research consortium consisting of Geoscience Australia, Geological Survey of Western Australia, Northern Territory Geological Survey, Newmont Mining and Tanami Gold. The Australian National Seismic Imaging Resource (ANSIR) was responsible for seismic data acquisition, as well as for field QC and preliminary in-field processing. The survey consisted of 720 line km along four regional deep seismic traverses, aimed at providing orthogonal three-dimensional control on the regional fault geometry. Raw data for this survey are available on request from clientservices@ga.gov.au

  • The data covers an area of approximately 4600 sq km in the Namoi Valley, located around Narrabri, NSW. The LiDAR was captured in September and October 2013 with a point density of two points per square metre. The specified accuracies; 30cm vertical and 80cm horizontal, were achieved and verified through a rigorous network of check points and base stations. A set of seamless products were produced including hydro-flattened bare earth DEMs, DSMs, Canopy Height Models (CHM) and Foliage Cover Models (FCM). The outputs of the project are compliant with National ICSM LiDAR Product Specifications and the NEDF. The survey was conducted over two areas along the Namoi River: one from Boggabri to Narrabri, and the other between Wee Waa and Walgett including a newer extension to this original area to the north east of Wee Waa.

  • AAMHatch has been engaged by Geoscience Australia to undertake a LiDAR survey over the BHMAR Phase 2 project area, for the purpose of producing a DTM and vegetation structure analysis. The survey covers an area of approximately 7856 sqkm of the Lower Darling River, downstream from Wilcannia. To this end, LiDAR data was acquired from a fixed wing aircraft between June 19th and August 5th 2009.

  • As part of the Australian Government's Onshore Energy Security Program (2006-2011) Geoscience Australia in collaboration with Geological Survey of Western Australia acquired magnetotelluric (MT) data along the deep crustal seismic reflection transect across the Yilgarn Craton, Officer Basin and Musgrave Province in Central Western Australia. The aim of the MT survey is to map the electrical resistivity distribution and improve scientific understanding of the crustal and upper mantle structure in this region. This information is complementary to that obtained from deep crustal seismic reflection, seismic refraction, potential field and geological data, which together provide new knowledge of the crustal architecture and geodynamics of the region. It is important for helping to determine the potential for both mineral and energy resources. Data are supplied as EDI files with support information.

  • Geoscience Australia conducted the Albany Fraser Orogen 2D Seismic Survey in 2012. The survey involves the acquisition of seismic reflection and gravity Data over the Yilgarn Craton margin and the Albany Fraser Orogen of Western Australia. The survey consisted of four lines, totalling 677kms. The project is a collaborative project between Geoscience Australia and the Geological Survey of Western Australia and is part of the ongoing cooperation under the National Geoscience Agreement (NGA). Funding of this project is through the Western Australian Government's Royalties for Regions Exploration Incentive Scheme. The primary objective of the project is to Image the crustal architecture of the Yilgarn Craton margin and its relationship to the Albany-Fraser Orogen and establish the subsurface extent of the Yilgarn Craton beneath the Albany-Fraser Orogen, and look for mantle-tapping structures that may have provided fluid pathways for mineralization. The seismic lines are designed to cross several major faults, such as the Cundeelee Fault, the Fraser Fault, the Newman Shear Zone, and the Red Island Shear Zone. A 70km long deep crustal seismic line was also acquired near the Tropicana Gold mine with the assistance of AuScope Earth Imaging, Anglo Gold Ashanti and the Independence Group. The purpose of this line was to image the crustal architecture as well as to understand the structural geometry around the Tropicana gold deposit and help define prospective areas elsewhere along the belt.

  • The AusLAMP-Victoria magnetotelluric survey was a collaborative project between the Geological Survey of Victoria and Geoscience Australia. Long period magnetotelluric data were acquired at 100 sites on a half degree grid spacing across Victoria in the south-east of Australia between December 2013 and September 2014. Some repeated sites were acquired in December 2017. Geoscience Australia managed the project and performed data acquisition, data processing, and data QA/QC. In this record, the field acquisition, data QA/QC, and data processing methodologies are discussed. A separate report will provide information on data analysis, data modelling/inversion, and data interpretation.

  • Processed seismic data (SEG-Y format) and TIFF images for the 2008 Rankins Springs Seismic Survey (L188), acquired by Geoscience Australia (GA) under the Onshore Energy Security Program (OESP), in conjunction with the New South Wales Department of Primary Industries (NSWDPI). Stack and migrated data are included for lines 08GA-RS1 and 08GA-RS2, as well as CDP coordinates. Raw data for this survey are available on request from clientservices@ga.gov.au

  • The L210 South Nicholson 1096 km-long deep seismic reflection lines were acquired from 6 June to 14 August, 2017. The survey involved the acquisition of seismic reflection and gravity data along five traverses, 17GA-SN1 (375 km), 17GA-SN2 (213 km), 17GA-SN3 (58 km), 17GA-SN3 (98 km), and 17GA-SN5 (352 km). The South Nicholson seismic survey was undertaken in collaboration with and funded by: The energy theme in Geoscience Australia - Exploring for the Future; Northern Territory Geological Survey (NTGS); Department of Natural Resources and Mines - through the Geological Survey of Queensland (GSQ); and AuScope.
