Telecom Cables Wanted For Climate Research 48
schliz writes "Oceanographers have called for telecommunications companies to use their active and retired submarine fibre to collect climate data. Sydney University's John You says voltmeters could simply be attached to cable landing stations to measure ocean currents via the electromagnetic current that they generate. More information about salinity and seismology could be collected by attaching sensors to repeater boxes that are typically installed every 100km of cable to amplify signals. Because fibre optic cables could remain under the sea for decades, they could be a consistent, continual source of data for researchers."

They do know they plow the cables into the sea bed floor. Something like 2m down. How is buried in the dirt/mud/sand going to read ocean currents, temp, salinity etc?
