Abstract:
1. An apparatus for recording magnetic field strengths in an area of the ocean comprising: an elongate canister having opposing upper and lower ends; a magnetometer sensor inside and at said upper end of said canister having sensitivity and resolution to detect magnetic field strengths of magnetic influence sweep systems and provide data signals representative of said detected magnetic field strengths; a computer processor in said canister being connected to said magnetometer sensor and programmed to control receipt and transmission of said detected magnetic field strength data signals; a memory device in said canister and coupled to said computer processor to store said detected magnetic field strength data signals; a power distribution system including at least one battery in said canister at said lower end of said canister and one or more electrical power distributing conductors coupled to said at least one battery and said magnetometer sensor, said computer processor and said memory device; a combination anchor release mechanism connected to the outside of said canister at said lower end; and an anchor releasably connected to said combination anchor release mechanism; an orientation sensor in said canister coupled to said computer processor, said memory device and said power distribution system and adapted to sense and provide data signals representative of the heading, pitch, and roll orientations of said magnetometer sensor; a temperature and depth sensor in said canister coupled to said computer processor, said memory device and said power distribution system and adapted to sense and provide data signals representative of temperature and depth of said magnetometer sensor; and a UHF transceiver inside and at said upper end of said canister having an antenna on the outside of said canister and coupled to said power distribution system and said computer processor to transmit and receive signals including collected data signals and remotely originating command signals.
