'Turbidity currents' diaporamas de présentation

Chapter Overview

Chapter Overview. Most waves are wind-driven. Most waves are generated by storms. Waves transmit energy across the ocean surface. Deep water and surf zone waves have different characteristics. Tsunami are special fast, long waves generated by seismic events. Wave Generation.
