We propose a simple spatio-temporal marked Poisson point process to describe the large structure of breaking waves in the ocean. The breaking events are "marked" with the associated local energy drop. This model is suitable for estimating dissipation at large scales (ocean currents) induced by small-scale events (waves breaking). Finally I will use a Gaussian model for the sea surface to calculate some notions of the probability of wave-breaking and the distribution of the associated energy drop. This is joint work with Juan Restrepo.
