Section description

Airborne geophysical survey
aircraft

Geoscience Australia's Continental Geophysics Section is an active concentration of specialists engaged in the acquisition, processing, archiving, enhancement, presentation and interpretation in the fields of airborne geophysics and gravity. The team also is involved in the development of new computational methods which can be applied to geophysical data. The Section's products and services are used by:

Geoscience Australia is the custodian of the most comprehensive publicly available Australian airborne magnetic, gamma-ray, elevation model and electromagnetic database and gravity database. The airborne geophysics database contains approximately 32.8 million line kilometres of data, which, at current prices, would cost approximately $197 million to acquire. The gravity database contains more than 1.57 million reliable onshore stations gathered during more than 1800 surveys. All the products and research results from the Continental Geophysics Section are publicly available for use by other government agencies, industry and research and educational institutions. Data from the Section is available also for inter-governmental and private sector cooperative acquisition, interpretation, research and training projects.

Section outcome

• New insights into Australia's onshore energy and mineral potential.
• Enhanced exploration strategies, promotion of mineral exploration opportunities and improved environmental management in Australia.
