The main objective of this investigation was to interpret and present the results of field measurements made by the National Institute of Oceanography, using a cloverleaf buoy and to compare these results with a development of a semi-empirical method for estimating the expected space average slope, vertical acceleration and velocity of the ocean surface for any given wind condition. Results of the chi-square test indicate that the distribution of slopes is in general Gaussian, while the acceleration distribution frequency shows non-Gaussian behavior. It was concluded that 1 the assumption of the wave system being composed of non-interacting linear deep water gravity waves with random phasing seems reasonable, that 2 the cosine square law for the angular dependence did not seem to be substantiated, and that 3 Phillips spectrum may be used to estimate the space average values of the total slope and acceleration for higher wind conditions.
