About this survey

Ninety long-period magnetotelluric soundings on the Stuart Shelf, South Australia, recorded by Adelaide University between 12 February and 28 June 2009 across the cover sequences above the eastern Gawler Craton. The soundings sit on a broad grid, 8.3 km between nearest neighbours at the median and 290 km end to end. Each site recorded Ex, Ey, Hx, Hy and Hz at 10 Hz on a Bartington fluxgate with orthogonal dipoles of 12 to 50 m, 81 occupations on Earth Data PR6-24 recorders and 16 on the Adelaide-Flinders Orange Box, and was processed to transfer functions with BIRRP. Served periods run 10.7 s to 8,192 s, 16 to 20 periods a sounding, and every file carries a tipper. The survey's own field record holds 97 occupations; seven are named in the archive without a released transfer function. README.md carries the caveats.
