Abstract

Unsupervised classification of marine data is helpful to identify relevant sea regimes, i.e. specific shapes that the distribution of wind and wave data takes under latent environmental conditions. We cluster multivariate marine data by estimating a multivariate hidden Markov model that integrates multivariate von Mises and normal densities. Taking this approach, we obtain a classification that accounts for the mixed (linear and circular) support of the observations, the temporal autocorrelation of the data, and the occurrence of missing values.
