Annual Index of Wind Wave Directional Spectra Measured at Harvest Platform 1994.

Abstract

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 2OO m depth contour approximately 20km 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. Ths report is the second in a series.
