Abstract: High-energy wave environments have made the maintenance of traditional, in situ wave gages expensive and unreliable. An alternative to traditional gages is wave estimates based on microseismic measurements. Microseisms are small ground motions of relatively high frequency (compared with seismic activity) which are observed as a background noise on standard seismographs located close to the shoreline. It is generally accepted that microseismic activity is related to ocean waves and the amplitudes of microseisms often correlate with wave energy. This work evaluates art existing wave meter system during summer wave conditions using digitally recorded data and computer analysis and investigates microseismic analysis techniques which might be useful to improve the seismic wave-measurement system.
