What does a wave look like from underwater?

See the waves from below—from under the water! It’s certainly impressive. Most people don’t realize that a wave rotates in a circle as it travels across the sea or ocean. When the wave reaches shallow water, the water column compresses and lifts the wave above sea level. With enough shallow water and energy, the wave “breaks,” and the circular rotation of the water creates a tube—the very thing surfers are so eager to ride.
