 "abstract": "One hundred and thirty one broadband and audio magnetotelluric soundings east of Tennant Creek, Northern Territory, recorded for Geoscience Australia by Zonge Engineering and Research Organization (Australia) between 22 July and 19 August 2019 under the Exploring for the Future programme, to help regional stratigraphic drilling resolve basement architecture and mineral potential beneath cover. The sites lie on north west to south east lines across about 98 by 118 km, 1.9 to 12.6 km from their nearest neighbour. Each recorded two electric and three magnetic channels on a Phoenix MTU-5A with MTC-150L coils and 100 m dipoles, at 150 Hz continuously plus 2,400 Hz and 24,000 Hz bursts, over 18 hours on average against a dedicated remote reference. Served here is Geoscience Australia's edited set, remote referenced in EPI-Kit, reviewed and trimmed in MT-Corrector, then edited with noisy data masked. The transfer functions span 9.61538e-05 s to 2270.66 s, 74 to 99 periods a site and 11,998 in all.",
