Description du projet
Capteurs et bouées connectées pour la mesure des vagues océaniques
Les mesures en temps réel des vents et des vagues sont essentielles, mais la technologie actuelle ne permet pas de fournir des informations sur les changements des conditions de l’air ou de l’eau au moment où ils surviennent. Il est donc difficile de réagir rapidement à l’évolution de l’état de la mer. Financé par le Conseil européen de la recherche, le projet REALTIMESEA abordera cette question en déployant des capteurs de vagues sans fil sur une bouée. Ceux-ci seront connectés pour transmettre des données brutes immédiates sur l’état de l’air et de l’eau à un endroit précis de la mer. Les informations seront envoyées à une station mobile avec des frais de communication minimes. Le projet exploite de nouveaux réseaux maritimes sans fil qui permettront de mesurer les vagues en temps réel. Des essais de démonstration du bien-fondé de la conception seront réalisés au cours d’une campagne d’un an au large de la côte d’Inis Meáin, en Irlande, dans le but d’optimiser le système de mesure, de développer un logiciel et de créer un manuel d’utilisation du kit.
Objectif
The ERC Advanced Grant HIGHWAVE is a current project that studies the physical mechanisms underlying the emergence of destructive breaking waves on the ocean’s surface. The recent months have shown the multiplication of abnormal atmospheric disturbances generating extreme winds and waves that surprised forecasters. It is therefore essential to be able to extract useful information from real-time measurements of winds and waves. In planning to address this problem from a science perspective, we discovered a critical gap in all current approaches to ocean wave measurements and maritime communications. There is no existing technology that provides air and water information (wave amplitude and direction, wind speed and direction, current speed and direction) of any given sea state in real time. The lack of any technique providing instant access to a sea state makes it extremely difficult to adapt to a changing sea state and to act fast.
REALTIMESEA will fill this gap, using wireless wave sensor technology deployed on a connected buoy to measure and transmit instantaneously to a fully equipped mobile station the raw data of the sea state (air and water) at a given location at a very low communication cost. Considering that our idea can be extended to a linked network of connected buoys, thus adding a spatial component to the real-time measurements, one can say that the ability to track sea states in real time and space will represent a revolution in wave forecasting, with expected commercial applications for multiple “end users”.
Taking the real-time measurement of waves to Proof of Concept is made possible because of the recent development of maritime wireless networks, that enables Wi-Fi data coverage over large areas of water within a 12 km radius from a shore station. A 1-year campaign off Inishmaan, Ireland, will allow the optimisation of the measurement system, the development of the required analysis software and of the manual for the buoy/mobile station kit.
