Brief description

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 eCat# 100444

Notes

Purpose
This collection of data is hosted at the NCI to make it easily accessible to the research community in a High Performance Computing environment as well as making it available to the general public as a national resource.
