Acquisition report to accompany Survey MT100164 https://geoscience.data.qld.gov.au/magnetotelluric/mt100164

From April to June 2021 the GSQ mobilised a four person geophysics field crew to the townships of Winton, Boulia and Bedourie, QLD. The crew collected a magnetotelluric survey as part of the New Economy Minerals Initiative of the Queensland Government. The work was undertaken with the support of Geoscience Australia.

Acquisition of 102 sites of broadband and audio MT data was undertaken at a site spacing of approximately 10 km. Sites were located along the major road, approximately 500 m from the road to minimise the impact of traffic noise. Five channel time series data were recorded at each site consisting of two orthogonal electric and three orthogonal magnetic field measurements. Sites were generally deployed for two nights providing data in the range of 0.0001 to 1000 seconds.
