| Definition | A geo-electromagnetic current meter based upon Stanford et al. (1978). The instrument measures the variations of horizontal velocity between the sea surface and bottom, based on the measurement of electric currents generated by the motion of the seawater through the Earth's magnetic field. The GEMCM supports a completely isolated measurement of the battery voltage in an instrument system and 2-component signals from a geo-electro-magnetic current meter. The instrument carries a 3-axis magnetometer that can be used as a compass. All outputs are digital and connect to the serial instrument bus. | ||
