HiWinGS Buoy Measurements of Wave Statistics and Energy Spectra
A wide variety of wind speeds and sea states were observed: 10-minute averaged Hs values during HiWinGS were between 1.38 and 11.4 m, and a 10-minute average U10 of greater than 15 m/s was observed for a total of 165 hours during the campaign.
Here we present a comparison between the wave measurements from the different buoys. We determine the capabilities of the buoys at measuring sea state in a variety of conditions and examine the reliability and accuracy of wind-sea/swell separations calculated from the 1-D spectra produced by the buoys. The spar buoys are found to represent the wave field, particularly local wind-sea, and separate wind-sea/swell energies more accurately than the waverider buoy.
