Abstract :
A Type 949 Heave WAVE-TRACK Buoy and a Waverider 6000 Series Buoy were moored at approximately 7.0 miles west of the Columbia River entrance off Astoria, Oregon from December 19, 1979 to January 5, 1980 in approximately 200 feet depth. Wave statistics derived from a zero-upcrossing analysis and energy spectra are compared. Wave period measurements compared closely, while wave height measurements differed by less than 7.5% for significant wave heights ranging from 2.2-4.6 m (7.5-15.2 ft) and maximum wave heights exceeded 8.5 m (28 ft). Energy spectra for the WAVE-TRACK Buoy fell within the 90% confidence limits of the Waverider Buoy spectra.
