 "abstract": "A broadband magnetotelluric survey of the Eyre Peninsula, South Australia, acquired under project H2X between November 2023 and November 2024. The package carries 374 transfer function files covering periods from 0.0001 to 6360 seconds: 25 on a north-south line inland from Arno Bay in 2023, 150 on a grid around Cleve in March 2024, and 199 on five lines, L0, L1, L6, L7 and L8, laid through the second half of 2024. Acquisition used LEMI-423 receivers with LEMI-120 coil pairs and Phoenix MTU-5C receivers with MTC-150 coil pairs, laid to geomagnetic north, with alternate sites along the 2024 lines taking each fleet. Processing was LEMIMT with a robust remote reference. Electric dipoles are short, 3.7 to 69.5 m, so the impedance estimates carry the noise sensitivity that implies. 84 files carry a tipper block, of which 45 are placeholders flat at unity that the engine masks. 15 files carry no acquisition date.",
