Projektbeschreibung
Sensoren und verknüpfte Bojen für ozeanische Wellenmessungen
Echtzeitmessungen von Winden und Wellen sind wichtig, aber die derzeitige Technologie kann keine Informationen über Veränderungen der Luft- oder Wasserbedingungen bereitstellen, während diese stattfinden. Dadurch wird es schwierig, schnell auf sich ändernde Meeresbedingungen zu reagieren. Das Team des vom Europäischen Forschungsrat finanzierten Projekts REALTIMESEA wird sich mit diesem Problem befassen, indem es drahtlose Wellensensoren auf einer Boje einsetzt. Diese werden miteinander verknüpft, um unmittelbare Rohdaten über den Luft- und Wasserzustand an einem bestimmten Meeresort zu übermitteln. Die Informationen werden mit minimalem Kommunikationsaufwand an eine Mobilstation gesendet. Das Projektteam nutzt neue drahtlose maritime Netze, die Echtzeitwellenmessungen ermöglichen werden. Während einer einjährigen Kampagne vor der Küste von Inishmaan, Irland, werden Tests zum Konzeptnachweis durchgeführt, um das Messsystem zu optimieren, Software zu entwickeln und ein Handbuch zu erstellen.
Ziel
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.
