GOMA MT survey had been done by Geocience Australia in Nov-Dec 2008. AuScope MT equipment were used for acquiring MT data along the deep crustal seismic reflection transect 2008GA-OM1 in South Australia. There were total 27 broadband (with prefix B*) and 12 long period (with prefix L*) MT sites. For broadband sites, 4 channels had been measured at 500 Hz sampling rate. Bx - North magnetic field, By - East magnetic field, Ex - North electric field and Ey - East electric field. For the long period sites, 5 channels had been measured at 10 Hz sampling rate. Bx - North magnetic field, By - East magnetic field, Bz - vertical magnetic field, Ex - North electric filed and Ey - East electric field. Processed data have been supplied as EDI files without any edit. Conditions of using the dataset: (1) express acknowledgement to Geocience Australia in any publication. (2) send a copy of any publication to Geocience Australia.
