Abstract
Magnetotelluric field measurements were carried out at two geothermally interesting locations with two Superconducting QUantum Interference Device (SQUID) magnetometers. The tests demonstrated the very attractive combination of characteristics of these instruments for geophysical magnetic measurements. They have noise levels down to 10-14 T/ Hz½ (10-5 gamma Hz-½); frequency response from 0 to several kHz; dynamic range of at least 160 dB; and in addition are portable and easy to set up in the field.Keywords
