Magnetic Field Modeling of the Northern Juan De Fuca and Explorer Plates

The Juan de Fuca and Explorer plates have been extensively surveyed over a period of several decades, primarily using shipborne scalar magnetometers, as noted by Raff and Mason 1961, Elvers et al. 1974, and more recently by Tivey and Johnson 1990. The original purpose for the analysis being presented here was to develop a practical method of identifying hazards to underwater navigation for the U.S. Navy, using magnetic techniques that take advantage of the Navys unique aeromagnetic survey resource, the Project MAGNET RP-3D Orion aircraft.
