"Perpetual Ocean"

[Ocean currents surrounding southern Africa, from NASA's website]

From the Rosentiel School of Marine and Atmospheric Science, in collaboration with the Gulf of Mexico Research Institute, "One of the primary goals of physical oceanography is to know the average movement of ocean water, everywhere around the globe. Besides knowing the average flow, it is also very useful to know how much this flow can change over a course of a day, over a year, over ten years, and longer. Ocean currents are organized flows that persist over some geographical region and over some time period such that water is transported from one part of the ocean to another part of the ocean. Currents also transport plankton, fish, heat, momentum, and chemicals such as salts, oxygen, and carbon dioxide. Currents are a significant component of the global biogeochemical and hydrological cycles. Knowledge of ocean currents is also extremely important for marine operations involving navigation, search and rescue at sea, and the dispersal of pollutants. "

"This visualization shows ocean surface currents around the world during the period from June 2005 through December 2007. The visualization does not include a narration or annotations; the goal was to use ocean flow data to create a simple, visceral experience." [from NASA'a website]

Note that this video only shows surface flows of the ocean, and not ocean flows at all depths.
