Georgina MT survey had been done by Geocience Australia in May-July 2009. AuScope MT equipment were used for acquiring MT data along the deep crustal seismic reflection transect 2009GA-GA1 in Northern Territory. There were total 39 broadband (with prefix GB*) and 18 long period (with prefix GL*) MT sites. For broadband sites, 4 channels had been measured at 1000 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.
