Now, researchers are using them to defend against earthquakes and produce an unprecedented map of the underground world Beneath the winding streets of Istanbul, Turkey, a fibre-optic cable pulses with laser light. The SUBMERSE (SUBMarinE cables for ReSearch and Exploration) project links Research and Education Networks (RENs), universities, research institutes and industry to establish multi-method monitoring along submarine optical telecommunication cables at several key oceanic cable routes branching off. The subsea telecom cables laid by civilian operators (like the one above) could be used to listen to all kinds of acoustic signals in the water column, with a wide range of scientific uses (File image courtesy Russian Ministry of Defense) [ByNancy Bazilchuk] The more-than 1. EU researchers are exploring how undersea communication cables can double-up as environmental and seismic sensors—a potential game-changer for early warning systems. These cables are the true backbone of the global internet, carrying over 95% of international data traffic and enabling everything from streaming Netflix and Zoom calls to global banking and cloud computing. In this article, we dive beneath the waves to explore how these submarine fiber optic.
