Airborne Electromagnetic data are being acquired by Geoscience Australia in areas considered to have potential for uranium or thorium mineralisation under the Australian Government's Onshore Energy Security Program (OESP). The surveys have been managed and interpreted by Geoscience Australia's Airborne Electromagnetic Acquisition and Interpretation project. In contrast to industry style deposit scale investigations, these surveys are designed to reveal new geological information at regional scale. The Frome Embayment AEM survey was acquired using the TEMPESTTM AEM system by Fugro Airborne Surveys under contract to GA. The survey covers a total of 32 300 line km and an area of 95 450 km2, the largest AEM survey by area ever flown in Australia.

Phase-1 data, that is, contractor quality-controlled and quality-assessed data for the Frome survey, were released during March 2011.

Phase-2 data, that is Geoscience Australia layered earth inversion (GA-LEI) data and derived products were released in July 2011 to 400m depth.

This data pacakge contains GA-LEI data and products to 200m and are described in the inversion report. This data and report are available from the GA AEM website.

Data quality

Lineage:

The release contains inversion conductivity models derived from the Frome AEM survey data, released in March 2011. The inversion method and products are described in detail in the report, included in the dataset.

Positional accuracy:

Positioning was via post-processed differential GPS methods. Horizontal positional accuracy of the data is approximately 1 metre (standard deviation).

Attribute accuracy:

The AEM data from which the inversions are derived have been acquired and processed to a standard of best practice as of the year 2010. More sophisticated processing algorithms may be applied to these data should they become available.

Logical Consistency:

Not applicable.

Completeness:

The dataset contains all conductivity models generated from the publicly released Frome AEM survey data.
