Abstract

BSTRACT A sea floor magnetometer Model OBM-S4 with a 0.1 nT resolution was designed, manufactured and tested. This meter has so far been used for the actual measurements at the sea floor several times, having proved to be a meter with excellent performance. This meter is characterized by the small size and light weight as well as free fall installation and acoustically controlled recovery.
