Abstract
A method for reducing motion induced voltage in marine electromagnetic measurements includes measuring an electromagnetic field parameter at at least one position along a sensor cable towed through a body of water. Motion of the sensor cable is measured at at least one position along the cable; Voltage induced in the cable is estimated from the motion measurements. The measured electromagnetic field parameter is corrected using the estimated voltages.
