    Distributed Acoustic Sensing (DAS) is an emerging technology that converts conventional fibre-optic (OF) cables into densely sampled acoustic arrays. By analysing Rayleigh backscattering from laser pulses, DAS detects strain changes along the cable, enabling continuous monitoring of subsea infrastructure and seismic events. Shear-wave velocity profiles are critical for assessing sediment...

    A22 Underwater Acoustics

    The INFN-LNS operates advanced deep-sea electro-optical infrastructures in the southeast of Sicily at the Portopalo site, supporting multidisciplinary research activities. These infrastructures were mainly installed for powering, control of deep-sea observatories and real-time data transmission. The existing optical fibers can also be exploited for optoacoustic sensing techniques. In this...

    A22 Underwater Acoustics

    Fiber-optic submarine cables instrumented with distributed acoustic sensing (DAS) provide a cost-effective solution for large-scale, real-time monitoring of fin whales. We present an automatic workflow for the detection, characterization, and localization of fin whale songs, developed and tested using data recorded on a telecom submarine optical cable in the Alboran Sea (westernmost part of...

    A22 Underwater Acoustics

    Distributed acoustic sensing (DAS) based on phase-sensitive optical time-domain reflectometry enables optical fibers to operate as dense underwater acoustic arrays with large aperture and continuous spatial sampling. This capability creates new opportunities for wide-area underwater acoustic monitoring and target detection. Nevertheless, applying conventional array signal processing techniques...
