One year of measurements in Alderney Race: preliminary results from database analysis
Résumé
The Alderney Race is assumed to have the largest tidal-stream energy potential in the North-Western European coastal seas. Interaction of the powerful tidal stream with strong wind, high waves and irregular bathymetry creates hydrodynamic conditions of extreme complexity, with high level of turbulence. A comprehensive dataset has beencreated to improve the understanding of physical processes, turbulence, tidal stream and resource variability at the site. The database contains a large amount of oceanographic and meteorological measurements acquired in Alderney Race in 2017–2018. This exceptionally long period of observations (nearly one year) became possible due to modern Tools and strategies of data acquisition. The paper présents some significant results from the database analysis. Among many results, we would like to underline the following: (i) a wide range of variability of mean flow and sea state parameters was documented; (ii) exceptionally large values of current velocity
