Energy on a breaking wave

What is the temporal and spatial distribution of energy on an ocean wave as it breaks? I.E. How much energy is in the trough, the pit, the peak and the shoulder? Does anyone have any sources or images demonstrating this? I've been trawling google scholar, the library, even youtube for the past 2 hours and not found anything about energy dissipation on an actual breaking wave. Any help would be greatly appreciated!
