Near the poles, the ocean is cold and the water sinks; near the equator, the surface of the ocean is inviting and warm - and floats on top of the colder deep water. So the question is this: Where does the water that goes down come back up? Some oceanographers now believe that it comes back up in the Southern Ocean surrounding Antarctica - not as much in the warm oceans as had been previously thought. [Source: Florida State University]
