On June 15, 2021, CARICOOS assisted the National Renewable Energy Laboratory (NREL) and the US Department of Energy (DOE) with the deployment of a wave buoy off the coast of Arecibo to provide wave observations for Puerto Rico’s northern coast. The observations will be used to measure wave energy in coastal ocean waters and to validate high-resolution numerical wave models, thereby aiding the engineering, design, and optimization of economical wave energy conversion devices. Also, the buoy data has been welcomed by surfers and fishers, among others. To view the data from Arecibo wave buoy, visit https://www.caricoos.org/station/arecibo/us .
