Ocean sound measurements collected from underwater gliders with marginal effects of flow noise

Pierre Cauchy

The Global Ocean Observing System recently designated ocean sound an essential ocean variable to support passive acoustic observation of the ocean. Underwater gliders have the demonstrated ability to fill gaps within usual ocean monitoring networks and are increasingly used for passive acoustic …

Machine learning meets the ocean: Predicting ship noise for marine mammals protection

Soukaina Boujdi, Loubna Benabbou, Pierre Cauchy

Underwater noise from ships is a growing pressure on marine mammals, affecting their ability to communicate, navigate, and interact. Existing noise prediction models have guided the field for decades but each has notable limitations. Ross relies on simplified log-linear relations derived from …

Harbor Porpoise and Beluga Whale Habitat Use in the Saguenay‐St. Lawrence Marine Park (Canada) Revealed by a Combination of Visual and Acoustic Survey

Coralie Bernier-Breton, Cristiane C. A. Martins, Gesche Winkler, Pierre Mercure-Boissonnault et autres

ABSTRACT Studying habitat use of cetaceans that spend most of their lives underwater poses challenges, prompting the use of complementary methods. Non‐invasive methods, land‐based surveys (LBS) and passive acoustic monitoring (PAM), were used to characterize occurrence patterns of beluga whales, harbor porpoises, …

Wind-dependent and traffic-generated noise in marine mammal habitat: Assessment across three frequency bands in the St. Lawrence estuary

Jeanne Mérindol, Cédric Gervaise, Pierre Mercure-Boissonnault, Guillaume St‐Onge et autres

Underwater sound is crucial for cetaceans, aiding behaviors such as foraging, communication, navigation, and reproduction. The St. Lawrence Estuary (eastern Canada), a key habitat for several cetacean species, also serves as a major shipping corridor connecting the Great Lakes to the Atlantic …

Passive acoustic monitoring from profiling floats as a pathway to scalable autonomous observations of global surface wind

Louise Delaigue, Pierre Cauchy, Dorian Cazau, Julien Bonnel et autres

Wind forcing plays a pivotal role in driving upper-ocean physical and biogeochemical processes, yet direct wind observations remain sparse in many regions of the global ocean. While passive acoustics have been used to estimate wind speed from moored and mobile platforms, their …

Effect of Gauge Length on Distributed Acoustic Effect of Gauge Length on Distributed Acoustic Sensing Performance for Baleen Whale Monitoring.

Marie‐Ève Clark, Pierre Cauchy, Stéphane Blouin, Léa Bouffaut

Distributed Acoustic Sensing (DAS) converts underwater fiber-optic cables into dense sensor arrays for marine monitoring, including ship and baleen whale detection. Detection performance is governed by the gauge length (GL), an acquisition setting set as a trade-off between optical signal-to-noise ratio (SNR) …

Multi-Representation Attention Framework for Underwater Bioacoustic Denoising and Recognition

Amine Razig, Youssef Soulaymani, Loubna Benabbou, Pierre Cauchy

Automated monitoring of marine mammals in the St. Lawrence Estuary faces extreme challenges: calls span low-frequency moans to ultrasonic clicks, often overlap, and are embedded in variable anthropogenic and environmental noise. We introduce a multi-step, attention-guided framework that first segments spectrograms to …
