Magnetic Anomaly Map Of The World

This map is the first global compilation of the wealth of magnetic anomaly information derived from more than 50 years of aeromagnetic surveys over land areas research vessel magnetometer traverses at sea and observations from earth orbiting satellites supplemented by anomaly values derived from oceanic crustal ages. Airborne measurement of the earths magnetic field over all of north america provides gridded data describing the magnetic anomaly caused by variations in earth materials and structure. We report here a simple but practical method to combine systematically the magnetic surveys of disparate specifications from marine ground aeromagnetic and satellite platforms that aims to be helpful in the framework of the world digital magnetic anomaly map project.
