A new ITU-T Technology Watch Report
highlights how submarine cables can be used as a real-time global network to monitor climate change and to provide tsunami warnings.
Future generations of cables and associated components could have the capacity to directly measure climate variables, such as water temperature, salinity and pressure on the ocean floor. All this could be achieved over long periods of time at low cost.
Despite a wide range of tools to monitor oceans, oceanographers cannot measure water variables at the sea floor. Using Submarine Communications Networks to Monitor the Climate
highlights how new and old submarine telecommunication cables could fill this gap.
The report, by Yuzhu You of the Institute of Marine Science, University of Sydney, Australia invites ITU experts to study the topic further, particularly with a view to identifying areas for standardization.
