Use of the techniques for the development of a European network of underwater platforms

Educational outreach by IRCCM

The first stage of the network will consist of 62 km (39.5 miles) of submarine cable and a single science node located 1,200 meters (almost 4,000 feet) below the ocean surface. The node will have four separate ports (docking stations) for oceanographic instruments. Each port will support bi-directional data transfers of up to 100 Mbits per second—comparable with some of the fastest land-based commercial data networks. The cable will also supply up to 10 kilowatts of power to the instruments-enough power to supply a small neighborhood, and several orders of magnitude more power than could be supplied using batteries alone
