Wave data obtained from simulations from an offshore basin and from field measurements were used to provide an assessment of the adequacy of describing the most likely time trace profile around large ocean wave crests based on the information provided by the autocorrelation function. It was concluded that the model is adequate in linear cases, but in high sea states, where nonlinear behavior is apparent, it starts becoming less appropriate.
