The waverider was destroyed by a tug. The wave data were acquired for application to physical models. completed notPlanned CoRIS_Metadata theme NCEI Geoportal Filter Oceanographic Coral Reef theme none Numeric Data Sets > Oceanography theme CoRIS Discovery Thesaurus EARTH SCIENCE > Oceans > Ocean Waves > Significant Wave Height EARTH SCIENCE > Oceans > Ocean Waves > Wave Period EARTH SCIENCE > Oceans > Ocean Temperature > Water Temperature EARTH SCIENCE > Atmosphere > Atmospheric Temperature > Air Temperature EARTH SCIENCE > Oceans > Coastal Processes > Coral Reefs EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment > In Situ Physical EARTH SCIENCE > Oceans > Ocean Waves > Wave Direction theme CoRIS Theme Thesaurus OCEAN BASIN > Pacific Ocean > Central Pacific Ocean > Hawaiian Islands > Oahu Island > Diamond Head (21N157W0016) COUNTRY/TERRITORY > United States of America > Hawaii > Honolulu > Diamond Head (21N157W0016) place CoRIS Place Thesaurus MHI place CoRIS Region sea surface stratum None These oceanographic data are PRELIMINARY data and have not been screened for accuracy.

Water Depth(m); 120 These wave rider data were obtained from Jerome Aucan and Mark Merrifield, University of Hawaii, via Julie Thomas, Scripps Institution of Oceanography, by Patrick Caldwell, NODC Liaison Officer, Honolulu, HI. Resource Description: NODC Accession Number 0000475 Entity and Attribute Overview: Hs - Significant wave height in meters; derived from the zeroth moment of the reported energy spectrum. Described as the "average height of the one third highest waves in the record". The US Army Corps of Engineers, Shore Protection Manual, 3-states that a useful estimate of significant wave height in deep water is defined as: Hs~4*sigma, where sigma is the standard deviation of the wave record. Statistically, the maximum wave height in the record is Hmax ~ 9*Hs/5. Tp - Peak period, in seconds; inverse of the frequency with the highest energy in the reported spectrum. Dp - Mean direction from which energy is coming at the peak period, in degrees clockwise from true North. Ta - Average period, in seconds; derived from the zeroth moment divided by the first moment of the reported energy spectrum. Temp - Air - Air temperature in degrees Celsius. Temp - Sea - Sea surface temperature in degrees Celsius. The data are provided as two types - parameters time series and 9-band time series.

The discrepancy between vertical movement of the Waverider and the movement of the sea surface is small. When a moored Waverider follows the waves, the force of the mooring line will change. This force is produced by the changing immersion of the buoy, resulting in a error of max. 1.5%. With decreasing wave length, the buoy will not follow the wave amplitude if the wave length is less than 5m [wave period below 1.8 sec.]. If the wave length is less than 2.5m [wave period 1.25 sec.] the buoy'sresponse decreases quickly. The Directional Waverider measures wave height in the same manner as the Waverider. The directional wave measurements are calculated from the x, y, and z accelerations of the buoy. Sample interval was 1 hz. Data saved in nominally 30 minutes intervals.
