Abstract
We examine free surface wave singularities that show a violent focusin g of energy. Periodic, modulated, and frequency locked wave states lea d to a state with fluid spikes. When the excitation of free surface wa ves exceeds a well defined threshold, the waves break leading to a low -dimensional aperiodic state with spikes, droplet ejection, and air en trainment. Return maps formed from wave height measurements lead to a low-dimensional model of the dynamics. Surprisingly, only a slight inc rease in power dissipation is observed past the transition to ejecting waves.
