Signals and noise in magnetotellurics [PDF]
SEG Technical Program Expanded Abstracts, 1985 Magnetotelluric noise properties were determined as a function of separation using an orthogonal array of stations. The simultaneous recording of high sensitivity biaxial tiltmeters along with the electric and magnetic fields allowed a measurement of the magnetic noise caused by sensor movement within the earth's static field.
