Underwater Cable Network: Capturing Processes in the Ocean

JAMSTEC has launched a new underwater cable network project (DONET) to cover the seismogenic zone offshore Kii Peninsula, central Japan. This project builds on lessons from past cable projects and aims to construct a core observation system composed of seismometers and pressure sensors. The planned infrastructure allows for future expansion of sensors to observe ocean processes to diagnose the condition of the Earth system. Furthermore, we believe the success of this project will mean expanding the cable network to the surroundings of Japan.
