"As you fly over the North Atlantic Ocean you will see awesome icebergs floating in those cold and icy waters. If you look carefully, you will see a pattern develop: small icebergs move in one direction and gigantic icebergs move in another. The surface winds drive the small icebergs while the huge ones are controlled by the deep ocean currents."
