In 2008, the Ord Irrigation Cooperative commissioned an airborne electromagnetics (AEM) survey of the ORIA Stage 1 and 2 areas to identify, quantify and understand any potential salinity risks in the current Ord irrigation area and the parts of the catchment that have been identified as potential future irrigation sites or potentially impacted by future irrigation. The project has been funded by the Australian and Western Australian governments through the National Action Plan for Salinity and Water Quality. Geoscience Australia and CSIRO were contracted to carry out the analysis and interpretation of the AEM dataset, and produce customised interpretation products. Some of the more specific questions it was hoped to address included: - Are we at risk of salinity in the Ord Catchment? - If so what areas are at the greatest risk? - Where can we target management to reduce this risk? - How can we plan future development to minimise salinity risk and maximise longevity of projects? The areas surveyed include the current Stage 1 Ord Irrigation Area, Stage 2 Irrigation Area (including Weaber and Knox Plains and Carlton Hill - Parry's Lagoon Conservation Area. The inclusion of undeveloped land in this survey is because the technology provides the opportunity to ensure any future irrigation development is guided by the best available information on soil type, aquifer quality and location and salinity risk. The information generated by this project will be publicly available and can be used for such things as: - Identifying leaky areas in the landscape that may require more concentrated management or can be designated for more suitable land use; - Where salt is stored in the landscape and at what depth, and where in the landscape it may influence plant growth; - Provide new constraints on the connectivity of aquifer systems in 3D across the ORIA and enable the construction of more realistic hydrogeological models to improve surface and groundwater management.

Dataset from the Vulcan Sub-basin containing depth based information regarding environmental analyses as exported from AGSO's RESFACS database.

These data are one of a set of 13 that captures a consistent horizon and fault interpretation of approximately 35 000 km of regional, mostly deep, seismic reflection data recorded by AGSO along the north and northwestern continental margins of Australia between 1990 and 1994.

Density and magnetic susceptibility measurements were taken from 254 rock samples in the Tanami region to provide rock property constraints during modelling. Multiple measurements were taken for each rock type, in each geological package, in order to provide a statistically representative sample for each package. The samples covered a large geographic portion of the model area, to account for any regional variations in rock properties. Samples selected for measurement were confined to rocks of the Tanami basement and the Birrindudu Group platform cover. Three rock sample datasets were accessed and consist of: Bureau of Mineral Resources (BMR) drill core collected during reconnaissance mapping of the Tanami Region in the early seventies (Blake, 1974) in order to penetrate cover and sample basement rock; NTGS hands samples collected as part their Tanami region project; and NTGS drill core collected as part their Tanami region project.
