a A functional block diagram of the magnetometer system. The dashed box indicates the magnetometer system that is installed in the pressure cylinder, and the black-filled boxes indicate connectors, respectively. b Photograph of the magnetometer system setup with the prototype model of the control board (without primary batteries) and the control board of the standard model. c Photograph of a setup appearance of the magnetometer system within the pressure cylinder. It was attached to an ocean-bottom seismometer (OBS) for the first in situ observation test on the seafloor
