Abstract : This report indexes parameters of and describes a means of access to 1.975 wind wave frequency-direction spectral observations obtained at the U.S. Army Engineer Waterways Experiment Station Field Research Facility from September 1993 to May 1994. 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. (MM)
