Descripción del proyecto
Sensores y boyas conectadas para medir el oleaje oceánico
Las mediciones en tiempo real de vientos y olas son fundamentales, pero la tecnología actual no puede proporcionar información sobre los cambios en las condiciones del aire o del agua en el momento en que se producen. Eso dificulta la respuesta rápida a los cambios en las condiciones del mar. El equipo del proyecto REALTIMESEA, financiado por el Consejo Europeo de Investigación, abordará este problema desplegando sensores inalámbricos de olas en una boya. Se conectarán para transmitir datos inmediatos y sin procesar sobre el estado del aire y del agua en un lugar marítimo concreto. La información se enviará a una estación móvil con unos gastos de comunicación mínimos. El equipo del proyecto aprovecha las nuevas redes inalámbricas marítimas que permitirán medir las olas en tiempo real. Las pruebas de concepto se llevarán a cabo durante una campaña de un año frente a las costas de Inishmaan (Irlanda), con el objetivo de optimizar el sistema de medición, desarrollar el «software» y crear un manual del kit.
Objetivo
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.
