Short summary

The first stage of field experiments involving the design and construction of a low power-consumption ocean bottom electro-magnetometer (OBEM) has been completed: this can be deployed more than 180 d on the seafloor with a time drift of less than 0.95 ppm. We found that the inclinations and magnetic data of the OBEM varied with two observed earthquakes when compared to the OBS data. The potential fields of the OBEM were slightly, but not obviously, affected by the earthquakes.
