 "abstract": "Eighty-five broadband magnetotelluric soundings on the Tropicana MT 2012 T1 traverse in Western Australia, which the registry pairs with seismic line 12GA-T1, recorded in 2012 by Moombarriga Geoscience. Sixty-eight LAV sites about 1 km apart were funded by AngloGold and seventeen LGA sites about 5 km apart by the Geological Survey of Western Australia. The LAV sites span 0.003 s to 2941 s; the LGA sites reach 1010 s to 1449 s. Every station carries impedance and tipper, and 43 mark the tipper empty at some periods. The files are served as the custodian released them: nothing is rotated and no static shift is applied. Every header prints one acquisition date, read month first as 1 October 2012; the registry gives 10 January 2012.",
