This ITU-T Technology Watch Report gives an overview
of how old and new submarine cables could be used for decades to come as
a major resource and 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
By encouraging technical standardization, ITU can facilitate implementation of this capacity.
