10.2 Waves at Sea – Introduction to Oceanography

In fluid dynamics, a wind wave, water wave, or wind-generated water wave, is a surface wave that occurs on the free surface of bodies of water as a result of the wind blowing over the water's surface. The contact distance in the direction of the wind is known as the fetch. Waves in the oceans can travel thousands of kilometers before reaching land. Wind waves on Earth range in size from small http://www.bom.gov.au/marine/knowledge-centre/reference/waves.shtml
