About Plateau du Four wave buoy
Plateau du Four is a CANDHIS station associated with the SEM-REV offshore test site off Loire-Atlantique. Located near a shallow offshore bank west of Le Croisic, it supplies environmental context for marine-energy research and for an exposed sector between the Loire estuary and southern Brittany.
Its current data source reports wave height, wave period, wave direction, directional spread and sea temperature.
