 "abstract": "A north to south broadband magnetotelluric line of 29 soundings across the Cariewerloo prospect in central South Australia, acquired by Adelaide University as an honours project in 2012. The line runs 99 km end to end near 137.04 degrees east, from 30.95 to 31.84 degrees south, at a median nearest neighbour spacing of 1.4 km. Each site recorded two electric and two magnetic components at 1000 Hz on an Earth Data PR6-24 logger with a LEMI-120 coil pair and a remote magnetic reference, processed into impedance with variances over 32 to 58 periods from 0.0064 to 2183.4 seconds. No file carries a tipper block, so no station publishes one. Every file declares a zero rotation on impedance and apparent resistivity, and AusMT serves each sounding in that stored frame. The owner's field record covers 15 of the 29 sites; the header dates are repaired into ISO 8601 and the delivered bytes kept in provenance. Caveats are in README.md.",
