Production of Ultra Low Frequency Magnetic Noise by Ocean Surface Gravity Waves and Its Real Time Removal from Airborne Magnetometer Measurements

Abstract

The major environment Ultra Low Frequency (ULF), magnetic noise sources observed on the airborne AN/ASQ-81(V) optically pumped magnetometer are electromagnetic micropulsatrons, geological structures and ocean wave noise. Experimental determinations of the amount of magnetic noise produced by ocean surface gravity waves were made. The author's current research designed to remove the wave noise and increase the probability of Magnetic Anomaly Detection (MAD) is summarized.
