Geophysical Grids
This Web Map Service contains Australian national scale grids of geophysical data, including Total Magnetic Intensity, Bouguer Gravity, and Gamma-Ray Spectrometry (radiometrics - K, Th, U). The grids were compiled by combining publically available government- and company-acquired airborne magnetic and radiometric surveys and ground-based gravity surveys in Australia and its surrounding marine area, and where appropriate, satellite-acquired data in the Australian region.

Radiometrics_U2Th_ratio_filtered_2015
Radiometrics U2/Th Ratio Image - 2015
Ratio of U-squared over Th derived from the filtered U and Th grids. The Radiometric Map of Australia dataset comprises grids of potassium (K), uranium (U) and thorium (Th) element concentrations, and derivatives of these grids. This third edition was derived by seamlessly merging 45 new survey grids with the Second Edition Radiometric Map of Australia (Minty et al., 2010). Details of the specifications of individual airborne surveys can be found in the 2014 Edition of the Index of Airborne Geophysical Surveys (Percival, 2014). Matching of the grids in the database was achieved using a program called Gridmerge, originally developed within Geoscience Australia and has now been commercialised. This program was used to merge 45 new surveys to the Second Edition Radiometric Map of Australia. The second edition merged over 550 individual grids to create the compilation (Minty et al., 2009), and the Australia-wide Airborne Geophysical Survey (AWAGS) airborne radiometric data was used to control the base levels of those survey grids which overlapped the AWAGS data (Milligan et al., 2009). As the second edition was used as a base grid for the Gridmerge operation the new Third Edition is essentially levelled to AWAGS. Filtering: Potassium, uranium, thorium and dose rate grids are available in both filtered and unfiltered versions. The low-pass filtering was achieved by applying a 7-point, degree-3 Savitzky-Golay filter (Savitzky and Golay, 1964) to each of the original survey grids prior to grid merging.

Radiometrics2015_filtered_dose
Radiometrics Filtered Dose Image - 2015
Terrestrial dose rate derived as a linear combination of the filtered K, U and Th grids described above (see Minty et al., 2009). Unit of measure = nG/h. The Radiometric Map of Australia dataset comprises gridsof potassium (K), uranium (U) and thorium (Th) element concentrations, and derivatives of these grids. This third edition was derived by seamlessly merging 45 new survey grids with the Second Edition Radiometric Map of Australia (Minty et al., 2010). Details of the specifications of individual airborne surveys can be found in the 2014 Edition of the Index of Airborne Geophysical Surveys (Percival, 2014). Matching of the grids in the database was achieved using a program called Gridmerge, originally developed within Geoscience Australia and has now been commercialised. This program was used to merge 45 new surveys to the Second Edition Radiometric Map of Australia. The second edition merged over 550 individual grids to create the compilation (Minty et al., 2009), and the Australia-wide Airborne Geophysical Survey (AWAGS) airborne radiometric data was used to control the base levels of those survey grids which overlapped the AWAGS data (Milligan et al., 2009). As the second edition was used as a base grid for the Gridmerge operation the new Third Edition is essentially levelled to AWAGS. Filtering: Potassium, uranium, thorium and dose rate grids are available in both filtered and unfiltered versions. The low-pass filtering was achieved by applying a 7-point, degree-3 Savitzky-Golay filter (Savitzky and Golay, 1964) to each of the original survey grids prior to grid merging.

Radiometrics2015_ternary_KThU
Radiometrics Ternary KThU image 2010
The national ternary radiometric image (2015 edition) shows the concentrations of the radioelements potassium (K), uranium (U) and thorium (Th) at the Earth's surface as measured using the airborne gamma-ray spectrometric method. The image is a false colour composite using the colours red, blue and green to represent potassium, uranium and thorium respectively. White areas have high concentrations of all the radioelements and dark areas have low concentrations. Areas high in K only appear red, and areas high in U and Th but low in K appear turquoise (a mixture of blue and green).

Gravity Anomaly image 2010 - HSI colour
Hue-Saturation-Intensity (HSI) colour image of the national Gravity Anomaly grid, 2010. This image is made from a grid that represents gravity anomalies of the Australian region. The grid combines accurate onshore gravity measurements, with satellite data over the offshore region. The cell values represent simple Bouguer anomalies at a density of 2.67 tonnes per cubic metre onshore and free-air anomalies offshore. The grid cell size is 0.5 minutes of arc, which is equivalent to about 800 metres.

TotalMagneticIntensityVRTP2015_greyscale
Total Magnetic Intensity - Variable Reduction to Pole (VRTP) greyscale image - 2015
The file is an image created from magmap_v6_2015_VRTP, a Variable Reduction to Pole TMI grid of the Australian region with a grid cell spacing of ~3 seconds of arc (approximately 80 m). This image only includes airborne-derived TMI data for onshore and near-offshore continental areas. The VRTP processing followed Cooper and Cowan's (2005) differential reduction to pole up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model (Finlay et al., 2010) using a data representative date of January 2005 and elevation 300 m.

TotalMagneticIntensity2015_HSI
Total Magnetic Intensity HSI colour image - 2015
The Total Magnetic Intensity (HSI colour) image is created from the magmap_v6_2015 which is a composite TMI grid of the Australian region with a grid cell spacing of ~3 seconds of arc (approximately 80 m). This image only includes airborne-derived TMI data for onshore and near-offshore continental areas. Since the fifth edition was released in 2010 data from 41 new surveys have been added to the database, acquired mainly by the State and Territory Geological Surveys. It is estimated that 31 500 000 line-kilometres of survey data were acquired to produce the grid data, 4 500 000 line-kilometres more than for the previous edition. Details of the specifications of individual airborne surveys can be found in the Fourteenth Edition of the Index of Airborne Geophysical Surveys (Percival, 2014). Matching of the grids in the database was achieved using a program called Gridmerge, which was originally developed within Geoscience Australia and has now been commercialised. This program was used to merge 41 new surveys to the 5th Edition Total Magnetic Intensity Anomaly Grid of Australia (Milligan et al., 2010). The 5th Edition merged 795 individual grids to create the compilation and to constrain long wavelengths, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of those survey grids which overlapped the AWAGS data (Milligan et al., 2009). As the 5th Edition was used as a base grid for the Gridmerge operation the new 6th Edition is essentially levelled to AWAGS. Individual and merged grids may be downloaded from the Geophysical Archive Data Delivery System (GADDS) on the Australian Government's Geoscience Portal at http://www.geoscience.gov.au/gadds.

AirborneSurveys2014
Airborne Geophysical Surveys - June 2014
This layer provides the outlines and specifications of 1085 airborne geophysical surveys conducted by or for the Australian, State and Territory governments. Most of the data for surveys referred to in this Index are available free on- line via the Geophysical Archive Data Delivery System (GADDS - http://www.geoscience.gov.au/gadds). They comprise more than 34 million line kilometres of mainly total magnetic intensity and gamma-ray spectrometric data. Land elevation data derived from GPS recordings made during airborne magnetic and gamma-ray spectrometric surveys, and electromagnetic data are also available for some areas. The associated index (Percival, P.J., 2014. Index of airborne geophysical surveys (Fourteenth Edition). Geoscience Australia Record 2014/014) contains the specifications of surveys.
