Hydroacoustic studies Fluid, methane flow/ tectonic movement Carbon mineralization rates Static versus dynamic process Lateral export of the carbon Vertical export of methane (ground thruthing of satellite data) 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 MBARI
