Real‐Time Detection and Prevention of DoS Attack in Unmanned Marine Vehicles Using Machine Learning

SECURITY AND PRIVACY, Volume 9, Issue 2, March/April 2026.
ABSTRACT Unmanned marine vehicles (UMVs) are one of the most crucial components of the underwater communication and surveillance system in the marine and oceanographic environment. This research introduces a novel approach to stabilize the connection in an unstable underwater environment by inheriting features of communication velocities.

Multipoint communications for underwater acoustic networks

, 2020
Dans ce sujet de thèse nous nous intéressons à la problématique des communications acoustiques multi-utilisateurs pour une flotte de drones sous-marins ou Autonomous Underwater Vehicle (AUV) en anglais. Pour cela, nous avons proposé 2 méthodes d’accès multiples basées sur la forme onde chirp que nous avons appelées MultiUser Chirp Spread Spectrum (MU ...

Low‐Frequency Ocean Waves Triggered by Tropical Cyclones via Seafloor Distributed Acoustic Sensing

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Propagation of low‐frequency ocean waves, including infragravity (IG) and internal waves, affect ocean dynamics and energy transfer within marine environments. IG waves are long‐period ocean surface waves that can propagate long distances across the ocean and impact the coastlines and deep ocean, while internal waves are buoyancy‐driven ...

Observations of Combined Wave and Current Interactions With a High Relief Coral Reef Bottom

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract On reefs, interaction between the flow and complex bottom topography results in drag forces on currents, dissipation of wave energy, and generation of turbulence. Here, field observations on a shallow backreef were used to investigate wave and current interactions with the bottom at scales of individual colonies across a coral reef patch. Wave

Quantifying Drag on Floating Sargassum Patches Under Combined Air and Water Forcing

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Laboratory experiments were conducted in a unidirectional air‐water flume with glass sidewalls to quantify drag forces acting on pelagic Sargassum spp. patches exposed to steady airflow and water current. Both live and surrogate patches, designed to replicate the morphology and buoyancy of natural sargassum, were tested over Reynolds numbers ...

Mechanisms Driving Transport and Accretion of Mud From Channels to Islands in a River‐Dominated Delta

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract River deltas are important landforms because they build coasts. Primary channels divide deltaic land into islands, which must accrete sediment fast enough for deltas to keep pace with sea level rise. Field observations are critical for determining the physical mechanisms that transport sediment between primary channels and islands, but are ...

Deep learning‐enhanced 3D imaging unveils semaglutide impact on cardiac fibrosis

British Journal of Pharmacology, Volume 183, Issue 5, Page 1030-1047, March 2026.
Background and Purpose Myocardial fibrosis (MF), a hallmark of structural cardiac remodelling, drives disease progression across most forms of heart failure and plays a central role in heart failure with preserved ejection fraction (HFpEF). Despite its clinical relevance, effective treatments remain scarce.
