High-frequency time series data of water surface elevation (used to derive surface wave heights) were acquired for 208 days at 11 locations approximately 200m offshore of Miami Beach, FL, in support of a study on wave transformation and dissipation by hybrid artificial reefs. The sensors were placed in three transects; two spanned across different designs of artificial reef structures ('SH' and 'TR' sites), and one placed across unaltered seabed to provide control data on natural seafloor ('CT' sites).
