Abstract: The directional distribution of wind-wave energy is an intuitively and demonstrably important aspect of sea state definition in coastal engineering design. Historically, there has been a shortage of high-resolution observations upon which to base engineering guidance. To remedy this, a multiyear series of measurements has been undertaken at the Field Research Facility of the Coastal Engineering Research Center, US Army Engineer Waterways Experiment Station. Cross spectra of surface-corrected signals from a linear array of nine bottom-mounted pressure sensors have been used in conjunction with an iterative maximum likelihood algorithm to estimate frequency-direction spectra. The array was located in about 8 m of water, approximately 900 m of £shore. This report provides an index of and describes a means of access to 636 frequency-direction spectral observations obtained nominally from September 1987 to August 1988. This period represents the second year of data.
