The major environmental 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.
