Full description

This dataset consists of MT data collected along a 42 km east-west transect across Paralana and Beverley in the northern Flinders Ranges. The survey consisted of 35 broadband stations at 1 km intervals and 15 long-period sites, 3 km apart. The first station started recording on day 120 at 0300 UTC, 2012, and the final station stopped recording on day 128 at 0300 UTC, 2012. Broadband stations were set out recording 4-components (Bx, By, Ex, Ey) using AuScope instruments, while Bartingtons fluxgate instruments were used at the long-period sites to record 5-components (Bx, By, Bz, Ex, Ey). Dipoles for all sites were ~50 m in length and consisted of non-polarising porous Cu-CuSO4 pot electrodes orientated towards geographic North and East, magnetoc induction coils were orientated parallel to the electrode dipoles. Broadband stations sampled at 500 Hz and recorded for two days before being moved to a new location. Long-period stations recorded for three days, sampled at 10 Hz, before being moved to a new station location. A site 60 km south-west of the survey line was chosen as the location for the broad-band remote referencing station, which operated continuously throughout the survey. The long period stations were remote referenced using magnetic observatory data collected in Alice Springs.
