Atmospheric waves form in the sky at the boundary between air masses of different densities.The giant wave in Lituya Bay that was described in the introduction to this chapter was a splash wave. Splash waves are formed when something falls into the ocean and creates a splash.They are also called seismic sea waves ( section 10.4). Tsunamis are large waves created as a result of earthquakes or other seismic disturbances.Tidal waves are not related to tsunamis, so don’t confuse the two. What we think of as tides are basically enormously long waves with a wavelength that may span half the globe (see section 11.1).

Tidal waves are due to the movement of the tides.

However, the height of the deep wave would be unnoticeable at the surface. These generally move more slowly than surface waves, and can be much larger, with heights exceeding 100 m. at a pycnocline), and propagate at depth.

Internal waves form at the boundaries of water masses of different densities (i.e.

We are most familiar with the kind of waves that break on shore, or rock a boat at sea, but there are many other types of waves that are important to oceanography: Waves generally begin as a disturbance of some kind, and the energy of that disturbance gets propagated in the form of waves.
