About this survey

Broadband magnetotelluric soundings over BHP's Seahorse project in south-east Western Australia, where the Eucla Basin covers the boundary between the Albany-Fraser Orogen and the Madura Province. Moombarriga Geoscience recorded them for BHP with Phoenix MTU-5C and MTU-8A receivers in two campaigns: 167 soundings on four transects, Seahorse South, Roma, Hippo and Morphy, from May to July 2022, and 278 in the Hippo, Dorsal and Morphy areas, 208 of them dated December 2022 to April 2023. The 445 soundings occupy 428 sites. 430 were remote referenced and 15 are local estimates; periods run 0.0001 s to 11,651 s and 444 carry a tipper. The 2022 files are EMpower spectra and the 2023 files Geotools impedance exports. The 2022 report says sensors were laid to magnetic north; nothing is rotated. 70 of the 2023 files state no acquisition date. The 2023 site tables name 453 further sites whose data the release does not hold.
