Objectives

Improve the scientific understanding of the structure and processes within the crust and upper mantle of continental Australia using seismic methods.

The key objectives of the Seismic Acquisition and Processing section are to:

• Manage and deliver the seismic and magntotelluric data acquisition and processing component of the Onshore Energy Security Program
• Operate the Geoscience Australia's component of the Australian National Seismic Imaging Resource (ANSIR). Support the ANSIR Director, Steering Committee and Access Committee
• Acquire, process, deliver and curate earth imaging datasets (land seismic, magntotelluric, etc) as approved by ANSIR for its external stakeholders and clients
• Maintain and improve data management for new and old survey datasets

Project description

Seismic Acquisition and Processing (SAP) is part of the Geophysics Group at Onshore Energy and Minerals Division (OEMD), and is a major part to the Australian National Seismic Imaging Resource (ANSIR).

Geoscience Australia has over 40 years' experience in land seismic surveys and since 1980 has acquired about 10,000 km of onshore deep seismic reflection data and numerous 2D seismic refraction profiles.

The Australian National Seismic Imaging Resource was Australia's first major National Research Facility dedicated to the Earth sciences. It continues as the National Research Facility for Earth Sounding, a joint venture of Geoscience Australia and the Research School of Earth Sciences at the Australian National University in June 1997 under the Australian Government’s Major National Research Facility Program.

A new tripartite agreement between Geoscience Australia, The Australian National University, and The University of Adelaide is under development for the continuation of the Facility.

The Seismic Acquisition and Processing section will focus on the projects for Onshore Energy Security Program (OESP) in the next four years, and will continue to operate other projects approved by ANSIR.

The major types of projects under the SAP are:

• Land seismic and magntotelluric surveys component for the OESP, including national and regional projects
• Land seismic surveys for State and Territory geological surveys
• Land seismic surveys for other Research groups, organisations and Industries. such as, AuScope, National Research Priority projects, Academic and Australian Research Council (ARC) Projects, CRC and SRC Projects, PMD*CRC projects.

Project outputs

• Field and processed earth imaging datasets (land seismic and magntotelluric) for the Onshore Energy Security Program
• Field and processed land seismic datasets for ANSIR's external stakeholders and clients
• Maintained, developed and enhanced data management
• Delivered survey reports, survey datasets to clients as requests via Internet and other methods
• Assisted users in developing and implementing Earth sounding research projects
• ANSIR activities annual reports

Project outcomes

• New insights into Australia’s onshore energy and mineral potential, which contribute significantly to the Onshore Energy Security Program
• Enhance mineral exploration strategies and promotion of Australia for mineral exploration through provision of an improved geological framework
• Enhance Australia's scientific and industrial competitiveness by keeping Australia at the leading edge of key technological developments in the field of imaging of the Earth’s crust using seismic and magnetotelluric techniques
• Increased understanding of mineral and geologic systems to encourage efficient investment in resource exploration
• Enhanced global attractiveness of Australian exploration investment opportunities
