Winds blowing across the ocean surface result in ocean waves. 
The movement of sea water at a pynocline creates internal waves. These waves are also called gravity waves.
Tidal forces (the period then equaling the tidal period) or in the action of a wind or pressure fluctuation can cause the waves.
