About St Mary's Sound wave buoy
St Mary's Sound station lies between St Mary's and St Agnes in the Isles of Scilly. The National Network first deployed a Datawell Directional WaveRider here in May 2014, establishing a nearshore record for an archipelago exposed to Atlantic swell and important to local navigation and coastal management.
Its current data source reports wave height, wave period, wave direction, directional spread, wave power and sea temperature.
