Abstract : This report indexes characterizing parameters of and describes a means of access to 2,339 wind wave frequency-direction spectra observed at the Texaco Oil Company Harvest Platform during calendar year 1993. Located at about the 200-m depth contour approximately 20 km west of Point Conception, California, the platform supports a spatial array of six pressure gauges, data from which are processed with an iterative maximum likelihood directional estimator. Nine parameters are defined, listed, and graphed in time series form: characteristic wave height, peak frequency, peak direction, four circular moment parameters, and two parameters derived from the quartile points of direction spectra.
