Abstract: A general maximum entropy estimate for the directional distribution of the directional wave spectrum is introduced. The estimate appears to be superior to conventional methods, including maximum likelihood methods, when ...

Abstract: It is shown that ocean-wave spectrum parameters obtained from spectra of time series measured with heave, pitch, and roll data buoys are maximum-likelihood (ML) estimators under certain assumptions about the wave field. A ...

Abstract: The paper discusses the estimation of directional wave spectra by the Iterative Maximum Likelihood Method. The performance of the estimate is illustrated using data obtained by an Acoustic Doppler Current Meter in the ...

Abstract: AbstractThe properties of directional distributions in ocean wave spectra are studied, with an emphasis on sea states with bimodal directional distributions in the high-frequency tails of single-peaked wave systems. A ...
