•When undisturbed by wind (or some other
factor such as an earthquake), the sea surface
is naturally smooth!
•Waves are moving energy and begin as a
–Wind blowing across the surface of the
ocean generates most waves
–Tides, turbidity currents, coastal landslides,
calving icebergs, and sea floor movement
can also cause waves
•In an ocean wave, energy is moving at the
speed of the wave, but water is not!
•Waves move energy, with very little
movement of particles (including water
•The water ‘associated’ with a wave does not
move continuously across the sea surface!
