Wave Patterns
Various subsurface currents conflict at times, causing bizarre wave patterns. One of the most noticeable of these is the Maelstrom. The word is derived from Nordic words meaning to grind and stream. Essentially, the maelstrom is a large, very powerful whirlpool, a large swirling body of water being drawn down and inward toward its center. This is usually the result of tidal currents.
Subsurface currents have a large effect on life on earth. They flow beneath the surface of the water, allowing them to be relatively free of external influence. Thus, they function like clockwork, providing nutrient transportation, water transfer, etc., as well as affecting the ocean floor and submarine processes.
