Fergusson River, NT, 1975 (P425), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Fergusson River, NT, 1975 survey were acquired in 1975 by the NT Government, and consisted of 15697 line-kilometres of data at 1500m line spacing and 150m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Inferred lithospheric mantle metasomatism

Building on the national-scale thermochemical tomographic inversions of Haynes & Afonso (2023), we infer regions of subduction-driven metasomatic alteration within the Australia sub-continental lithospheric mantle. Such regions are inferred on the basis of age-corrected magnesium number anomalies for bulk composition of the lithospheric mantle, and the spatial correlation of these features with electrical conductors. This defines a mappable criteria for mineral system conceptual models focused on the transport of melts from re-enriched upper mantle sources. Mapping this feature through stochastic uncertainty propogation of inferred mantle compositions enables us to quantify the level of agreement in the spatial constraints on the feature. Here, we present a voting map that quantifies the relative presence or absence of such features across Australia under any arbitrary model realisation.

Geoscience Australia's Exploring for the Future program provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources. By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia's geology and resource potential. This leads to a strong economy, resilient society and sustainable environment for the benefit of all Australians. This includes supporting Australia's transition to a low emissions economy, strong resources and agriculture sectors, and economic opportunities and social benefits for Australia's regional and remote communities. The Exploring for the Future program, which commenced in 2016, is an eight year, $225m investment by the Australian Government.

Percy Isles 1:250 000, R502 historical topographic map

The R502 series of maps has been replaced by the National Topographic Map Series (NTMS). The R502 series consists of 542 map sheets and covers Australia at a scale of 1:250,000. It was compiled from aerial photography, but only about one quarter of the series was contoured. The standard sheet size is 1 degree of latitude by 1.5 degrees of longitude. Transverse Mercator map projection and Clark 1858 datum were used. Coverage of the country was completed in 1968.

Ord Valley AEM Interpretation Project - GIS

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.
