The Australian Energy Resource Assessment (AERA) examines the nation's identified and potential energy resources, ranging from fossil fuels and uranium to renewables. The assessment reviews the factors likely to influence the use of Australia's energy resources to 2030, including the technologies being developed to extract energy more efficiently and cleanly from existing and new energy sources.
AERA was undertaken jointly by Geoscience Australia and the Australian Bureau of Agricultural and Resource Economics (ABARE) at the request of the Department of Resources, Energy and Tourism as a contribution to future energy policy.
The AERA is available in printed, CD-ROM and PDF formats.
The Capricorn deep crustal seismic survey in the Pilbara/Gascoyne region of Western Australia has been completed. This is a collaborative project between Geoscience Australia, the Geological Survey of Western Australia (GSWA) and AuScope Earth Imaging (a component of NCRIS). It consisted of 579 line kilometres of reflection seismic and gravity data aimed at imaging the extent of the Archean crust beneath the Capricorn Orgeny and identifying the relationship between the Pilbara and Yilgarn cratons. Data is now being processed with the aim of release in early 2011.
The Youanmi deep crustal seismic survey commenced on 21 May 2010 and is a collaborative project between Geoscience Australia and GSWA. Reflection seismic, gravity and magnetotelluric data will be acquired over three traverses, totalling 677km, crossing the Youanmi Terrace and Eastern Goldfields Superterrance of the Yilgarn Craton.

Geoscience Australia has released An assessment of the uranium and geothermal potential of north Queensland. This report presents an assessment of the uranium and geothermal potential of north Queensland developed using a geosystems approach and regional datasets, including geophysical, geological, geochemical and aquifer data. Uranium systems considered include sandstone-hosted, unconformity-related, metasomatic, iron-oxide copper-gold-uranium and magmatic-related systems. Geothermal systems assessed include hot rock and hot sedimentary aquifer systems. The analysis highlighted known districts and new areas, including extensions of known districts undercover.

The Index of Airborne Geophysical Surveys (11th edition), was released by Geoscience Australia on 26 May 2010. The new edition is the latest compilation of metadata of Australian open file government airborne surveys and supersedes the previous 10th edition (December 2008). The Index includes specifications of approximately 1050 surveys conducted between 1951 and May 2010. It is made up of more than 29.5 million line kilometres of mainly total magnetic intensity, gamma-ray spectrometric and land elevation data. Specifications for each survey are presented in tabular format, with four surveys per page arranged in numerical order and based on assigned Geoscience Australia Project Numbers.
Clients can quickly identify airborne surveys of interest and obtain the relevant metadata by using two lookup tables:
- A table listing survey names in alphabetical order, with corresponding Geoscience Australia Project Numbers and
- A table listing 1:250 000 map sheet names in alphabetical order, along with Geoscience Australia Project Numbers of surveys located on each map sheet.
Also included are two maps, the May 2010 edition of the aeromagnetic map and the gamma-ray survey index map, each of which indicate the standard of data coverage (based on survey line spacing) over Australia in relation to 1:250 000 map sheets. Areas covered by new surveys acquired by the States during 2009/10 also are shown on these maps.
For information email email@example.com; or phone +61 2 6249 9578.
The seismic lines were collected as part of the Onshore Energy Security Program, in conjunction with the Department of Primary Industries and Resources, South Australia. The lines presented include the Curnamona, Gawler-Curnamona link and the Arrowie and Eyre Peninsula transects. Results are also included from MT surveys and inversion modelling as well as some of the implications of the datasets for regional energy systems.

The current status of Geoscience Australia's geophysical survey data acquisition is now available in a comprehensive table.
The Eucla Basin airborne magnetic and radiometric surveys are due to commence early June 2010.
