Abstract :
We newly developed an electric field observation system on seafloor by using a long ocean bottom cable. Such large-scale electric field includes signal from the earth´s core. The system is designed to enable us to make an observation wherever we need. We successfully deployed the system on the seafloor off Daito-jima Island, Japan, with the cable extension of about 10 km length
