Abstract : This report indexes parameters of and describes a means of access to 3,581 wind wave frequency direction spectral observations obtained at the U.S. Army Engineer Waterways Experiment Station Field Research Facility from June 1994 to August 1995, a period that encompasses the DUCK94 Experiment. An iterative maximum likelihood algorithm is used to estimate directional spectra using signals from a spatial array of 16 bottom mounted pressure sensors in about 8 m of water, approximately 900 m offshore. Parameters include characteristic wave height, spectral peak frequency and corresponding peak period, peak wave direction, directional spread, and reflection coefficient. Time series graphs of these parameters, as well as local winds and currents, illustrate the salient climatology.
