During 2007 and 2008 and under the Australian Government's Onshore Energy Security Initiative, Geoscience Australia acquired airborne electromagnetic (AEM) data over the Paterson Province of Western Australia. The main purpose of the survey was to provide additional geophysical/geological context for unconformity and palaeochannel style uranium mineral systems and thereby promote related exploration. The survey data will also provide information on depth to basement, which is of general interest to explorers, and will be used as an input into a ground water evaluation of the region.

Airborne gravity data set flown in 2003 by Fugro Airborne Surveys Pty LTD in association with Canadian Micro Gravity Pty Ltd using their GT1-A gravimeter. Processing carried out by Canadian Micro Gravity Pty Ltd. Survey located in East Alligator area of West Arnhem Land. Lines flown east-west at constant barometric height of 600m asl. Total line kilometres is 4,500. The data set is included as a separate directory on the CD-ROM containing the March 2004 release of the Australian National Gravity Database. See Geocat entry # 61045.

During 2008 and 2009, and under the Australian Government's Onshore Energy Security Initiative, Geoscience Australia acquired airborne electromagnetic (AEM) data over the Pine Creek Orogen of the Northern Territory. The survey area was split into three areas for acquisition. VTEM data was acquired in the Kombolgie area east of Kakadu National Park between August and November 2008. TEMPEST data was acquired west of Kakadu National Park with the area split in two to facilitate the use of two aircraft: the Woolner Granite area in the north was acquired between October and December 2008; and the Rum Jungle area (this data set) adjoining to the south, which was acquired between October 2008 and May 2009. The main purpose of the surveys was to provide additional geophysical/geological context for unconformity style uranium mineral systems and thereby promote related exploration. The survey data will also provide information on depth to Proterozoic/Archean basement, which is of general interest to explorers, and will be used as an input into ground water studues in the region.

Data acquired as part of the Kombolgie VTEMTM Airborne Electromagnetic Survey have been inverted using a layered earth inversion algorithm. Interpretation products have been derived from the inversion results. The inversion results and derived products have been released by Geoscience Australia as a digital data package. The survey was funded under the Australian Government's Onshore Energy Security Program, and was managed and interpreted by Geoscience Australia's Airborne Electromagnetic Acquisition and Interpretation Project. The Kombolgie survey area, in the Pine Creek Orogen of the Northern Territory, covered sections of the Cobourg Peninsula, Junction Bay, Alligator River, Milingimbi, Mount Evelyn, Katherine, and Urapunga 1:250 000 map sheets. It covered a total of 8 800 line km and an area of 32 000 km2. The data were acquired under contract by Geotech Airborne Pty. Ltd. using its VTEMTM helicopter-borne electromagnetic system. The inversions were carried out using the GA-LEI layered-earth inversion software developed at Geoscience Australia. Products include the layer conductivities, depth and elevation slices, and sections. The products are in digital form in both point-located and gridded formats. They are available for download from the Geoscience Australia website.
