AB  - Oceanic airentraining breaking waves fundamentally influence weather and climate through bubblemediated oceanatmosphere exchanges, and influence marine engineering design by impacting statistics of wave heights, crest heights, and wave loading. However, estimating individual breaking wave energy dissipation in the field remains a fundamental problem. Using laboratory experiments, we introduce a new method to estimate energy dissipation by individual breaking waves using abovewater images of evolving foam. The data show the volume of the breaking wave twophase flow integrated in time during active breaking scales linearly with wave energy dissipated. To determine the volume timeintegral, abovewater images of surface foam provide the breaking wave timescale and horizontal extent of the submerged bubble plume, and the foam decay time provides an estimate of the bubble plume penetration depth. We anticipate that this novel remote sensing method will improve predictions of airsea exchanges, validate models of wave energy dissipation, and inform ocean engineering design.
