Deployment of the junction unit for Off-Toyohashi cabled observatory
A new cabled observatory was constructed off Toyohashi in central Japan using a pair of decommissioned underwater telecommunication cables. While providing electric power and communication line to the underwater observatory, the cables will be used as a long active antenna to monitor the electro-magnetic properties of the Earth's crust that are related to water contents. To secure a safe deployment of the junction unit at the end of the cable, we conducted computer simulations before the deployment. The junction units must usually be placed exactly as planned. This paper presents that the simulation results coincide with the actual construction result.
