Abstract
The Geophysical Data Collection hosted at the National Computational Infrastructure (NCI) contains individual airborne survey lines of geophysical data, including Total Magnetic Intensity, Gamma-ray spectrometry (radiometrics - K, Th, U) and elevation, as well as, ground based Bouguer Gravity. These datasets have been used to create both survey scale and national grids for the geophysical data types. The data were sourced from publicly available government- and company-acquired geophysical surveys in Australia and its surrounding marine area. Other GA Geophysical Data Collections not held at the NCI are discoverable via <a href="https://pid.geoscience.gov.au/dataset/ga/100444">eCat# 100444</a>

Lineage
The Geophysical Data Collection hosted at the NCI contains a substantial number of magnetics, radiometrics, elevation, airborne electromagnetics, and ground based gravity survey data acquired mainly by the Commonwealth, State and Northern Territory Governments, and the private sector. The data quality varies depending on the survey. The data are processed via standard methods to ensure the response recorded in the data 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 are checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose and the data were transformed into the NetCDF format to ensure correct standardisation and for hosting at the NCI. The airborne survey data is available with the elevation as collected and with the elevation corrected using the Australia Wide Airborne Geophysical Survey (AWAGS) collection.
