Marine waves are disturbances on the surface of oceans and seas, primarily caused by the wind. As the wind blows across the water, it transfers energy, creating ripples that can grow into larger waves. These waves can vary in size and shape, depending on factors like wind speed, duration, and the distance over which the wind blows, known as fetch. Waves play a crucial role in marine ecosystems, influencing coastal erosion and sediment transport. They also affect navigation and can impact weather patterns. Understanding marine waves is essential for activities such as surfing, fishing, and shipping, as well as for coastal management and safety.
