Waverider buoys have collected observations and measurements on wave characteristics including wave height and period statistics. Waverider buoys are located in the Galway Bay 1/4 Scale Test Site and the Full Scale Atlantic Marine Energy Test Site (AMETS) located off the Erris Peninsula near Belullet. Waveriders first deployed in 2006 with main deployments from 2008 onwards. Waveriders have collected data on waves using latest instrumentation technologies to reflect the real conditions experienced. Waveriders have been managed by the Marine Institute (Ireland) in partnership with the Sustainable Energy Authority of Ireland. Dataset complete for functional periods of observations. Any incomplete periods reflect instrumentation offline due to adverse weather conditions and or maintenance
