Abstract

An ocean bottom proton magnetometer was built and tested at the bottom of the sea. The sensor, preamplifier, preamp-control, and battery are placed at sea floor and are connected to a land station by a single coaxial cable of 3, 000 meters. Selection of tuning capacitors, data transmission, and battery charging are carried out through the cable and the device can be operated as if it is at hand.
