A magnetic anomaly detection buoy includes an elongated body having a cavity disposed therein, a means for detecting a magnetic anomaly and producing an output in response thereto, and a means for maintaining the elongated body in a state of buoyant repose within a fluid medium. A radio transmitter, disposed within the cavity of the elongated body, for electrical communication with the detecting means. The radio transmitter receives the output from the means for detecting the magnetic anomaly and transmits a radio signal in response thereto. A method for detecting a magnetic field anomaly includes deploying a magnetic anomaly detection buoy into a large body of water and determining a first flux value representing the magnetic flux of the environmental magnetic field conditions. The first flux value is then stored for future reference. The environmental magnetic field conditions are evaluated and a second flux value is determined. If the second flux value is greater than the first flux value, information is transmitted via radio waves.

[ I claim:] [1.] A magnetic anomaly detection buoy comprising:an elongated body defining an interior cavity;a magnetometer which produces an output in response to a detected magnetic anomaly;a magnetic detection computer disposed within the cavity of the elongated body which measures the output from the magnetometer and produces an activation signal when the measured output exceeds a threshold value;a transducer which detects acoustical information;a solid state recorder disposed within the cavity of the elongated body which records the detected acoustical information in response to the activation signal from the magnetic detection computer; andan inflatable float which maintains the elongated buoy in a state of buoyant repose.
