AbstractMeasurements of the above-deck magnetic field of a ship with a steel hull (HMCS "Stettler") were carried out to determine the feasibility of a grandiometer method of "M" magnetic field detection which has been proposed for use with a closed-loop degaussing system. The region first investigated (from the funnel to an area 20 feet aft of the funnel) was found to have a strong magnetic field due to the funnel structure. A grandiometer could not be used to detect the ship's general field in this region. Further magnetic surveys disclosed an area 40 feet aft of the funnel and 20 to 26 feet above the deck, in which suitable locations for the "M" field detector exist.
