The United States Naval Oceanographic Office is conducting an airborne geomagnetic survey of ocean areas. The purpose of this program, known as Project MAGNET, is to acquire more accurate and adequate data for the improvement of navigational and world isomagnetic charts. The current flight operations are being conducted as part of the over-all survey of the world's ocean areas.
The survey aircraft, a modified U.S. Navy transport plane, operated by Oceanographic Development Squadron Eight, is equipped with a vector airborne magnetometer and special navigation equipment. The airborne magnetometer measures the intensity and direction of the earth's magnetic field, thereby providing information for charting all elements of the field.
