Prefiguration of an observatory of marine ecosystems in interaction with floating offshore wind farms in the Gulf of Lion
Duration: 24 months (2020 - 2022)
In 2021, three pilot floating offshore wind farms will be operational in the Gulf of Lion. In addition, the consultation organised by the Interregional Directorate for the Mediterranean Sea made it possible to define 4 macro-zones, covering a total area of 3,300 km², on which calls for tenders for commercial farms could be launched as part of the new French multiannual energy programming.
The integration of infrastructure such as floating wind turbines into the complex, fragile and coveted marine coastal ecosystems is a challenge. Despite research carried out in various settings, including many scientific programmes, our understanding of marine ecosystems, integrating all their components (avifauna, plankton, ichthyofauna, mammals, etc.), is still insufficient. The development of observation series has often been suggested to overcome this lack of data and knowledge.
The establishment of a high frequency observatory would provide the necessary knowledge to better understand the interactions between floating wind turbines and marine ecosystems in order to optimize the environmental integration of commercial parks.
To propose a high-frequency observatory architecture that can rely on the underwater cable network of the Gulf of Lion to determine the state and evolution of marine ecosystems in interaction with high-power floating wind farms.
Scientific and technical contents
- State of the art of knowledge and available means of observation concerning the functioning of Mediterranean marine ecosystems (fish, cetaceans…).
- Evaluation of the instrumentation currently used and/or developed by academic research and the private sector.
- Synthesis of the measurement needs for the observation of marine ecosystems and the associated technical and environmental constraints.
- Drafting of specifications for potential architectures of observation networks.
Partners and funding
This project is led by Pôle Mer Méditerranée.
The total project budget is €470K.
This project receives funding from the French Agency for Energy Transition under the auspices of the call for sustainable energy research projects (2018-2019).
