 "abstract": "A broadband magnetotelluric infill of the eastern half of the February 2010 Southern Delamerian transect, acquired by Adelaide University between 14 and 21 June 2012 in the Delamerian Orogen of western Victoria. Thirty-eight soundings run 67 km west to east along the parent line at a median nearest neighbour spacing of 1.3 km, against the 4.9 km median step of the 14 parent stations they sit among. Each site recorded two electric and two horizontal magnetic components on an Earth Data PR6-24 with LEMI-120 coils, sampled at 1000 Hz for about a day. A vertical channel was digitised but no coil was connected to it, so every tipper block is zero and no station publishes a tipper. Soundings span 0.0064 to 2183 s over 23 to 56 periods. The files are the custodian's own Geotools export and are served in the frame they declare, with their header dates repaired; caveats are in README.md.",
