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 [16] TOWED THROUGH A BODY OF WATER [11]. MOTION OF THE SENSOR CABLE [16] IS MEASURED AT AT LEAST ONE POSITION ALONG THE CABLE [16]; VOLTAGE INDUCED IN THE CABLE [16] IS ESTIMATED FROM THE MOTION MEASUREMENTS. THE MEASURED ELECTROMAGNETIC FIELD PARAMETER IS CORRECTED USING THE ESTIMATED VOLTAGES. [FIG.1]
