Listening across the oceans: Distributed acoustic sensing

Written by
A yellow fibre optic cable is lying across the bottom of the sea floor. These cables are useful as sensors for distributed acoustic sensing for sea life surveillance and protection

Fibre optic cables have become the backbone of digital communication across the oceans. These cables are not just useful for transmitting information from one location to another – they can also be used as an incredibly long sensor array in themselves. Distributed acoustic sensing (DAS) is a powerful way of measuring sound and vibrations in the sea floor. Dr Ole […]
