The Australia-Wide Array of Geomagnetic Stations (AWAGS)

The Australia-Wide Array of Geomagnetic Stations survey was an array of 58 vector magnetometers covering mainland Australia, but not Tasmania, and comprised 54 portable three-component magnetometers plus four permanent magnetic observatories. Time-series of geomagnetic field fluctuations were recorded at 1-minute intervals with 1 nanoTesla sensitivity, together with sensor temperature and time. The portable magnetometers in the array were programmed to commence recording simultaneously on 18 November 1989. Most instruments were kept operating for a nominal interval of 8 months. The last data were recorded on 17 December 1990.The survey was run jointly by Flinders University of South Australia and Geoscience Australia (previously the Australian Geological Survey Organisation).
