Abstract

SAMMENDRAG Det beskrives en fremgangsmåte for behandling av marine magnetiske data, hvilken omfatter å slepe et første og et andre magnetometer M1 og M2 etter et skip (10). Magnetisk-gradient-rådata innhentes fra sensorene, og trenden til skipspåvirkningsgradienten detektert av sensorene bestemmes. Fremgangsmåten innbefatter å subtrahere trenden fra magnetisk-gradient-rådataene for å oppnå korrigerte gradientdata, og å behandle de korrigerte gradientdata for å tilveiebringe utdata.SUMMARY A method for processing marine magnetic data is described, which includes towing a first and a second magnetometer M1 and M2 after a ship (10). Magnetic gradient raw data is obtained from the sensors and the trend of the ship impact gradient detected by the sensors is determined. The method includes subtracting the trend from the magnetic-gradient raw data to obtain corrected gradient data, and processing the corrected gradient data to provide output.
