A new European Marine Board Working Group is assessing how obsolete, active and newly laid submarine telecommunication cables can strengthen ocean monitoring. Its kick-off meeting was held at IMREDD, Université Côte d'Azur, in Nice on 8 September 2026.
New paper in The Seismic Record: by removing the common-mode instrumental noise, we detect Earth's normal modes on a seafloor telecom cable offshore Monaco — showing that DAS can be used in the low-frequency regime long considered out of reach.
Honoured to give a keynote at the SUBMERSE Final Event in Copenhagen, bringing together 25 European partners sharing on three years of progress on submarine fibre-optic sensing.
Our team will present four contributions at the Ocean Sciences Meeting in Glasgow, Scotland, showcasing new advances in Distributed Acoustic Sensing for ocean monitoring, biodiversity, and geodesy.
Peer-reviewed results show that DAS on existing seafloor telecom cables can detect tsunami-induced strains and support low-cost, near-field early warning.
The fin whale is a key species in marine ecosystems and a sensitive indicator of ocean health. Yet monitoring its low-frequency calls at scale remains challenging. Distributed acoustic sensing (DAS) on subsea fiber cables can record thousands of …
New publication in JASA presenting a deep-learning pipeline for detecting fin whale calls using DAS data from the Arctic and Mediterranean.
This study investigates the sensitivity of Distributed Acoustic Sensing (DAS) to small-scale heterogeneities in the subsurface. Through numerical modeling and homogenization theory, we show that DAS strain measurements are highly sensitive to these heterogeneities, unlike traditional velocity measurements, which has implications for various applications.
