The French Channel coast, which already has highly developed human activities, is particularly concerned by the deployment of offshore wind farms. However, qualifying the effects of commercial wind farms on a local scale, and the cumulative impacts of the various uses of the sea on the environment on a coastline scale, remains a major research challenge. This requires the long-term acquisition of field data, which is made possible using a measuring mast located off Fécamp and belonging to France Energies Marines. The mast is a genuine research platform at sea where state-of-the-art instrumentation is deployed, and innovative monitoring protocols are developed. This is a first in France to support the sector’s industrialists and the State with field studies, while encouraging their collaboration with the various research players.
