1 3. ABSTRACT (Maximum 200 words) 



This report indexes characteristic parameters of and describes a means of access to 2,320 wind wave frequency-direction 

 spectra observed at the Texaco Oil Company Harvest Platform during calendar year 1994. 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 

 moments (mean direction, width, skewness, and kurtosis), and two parameters (directional spread and asymmetry) derived 

 from quartile points of directional spectra. This report is the second in a series.
