B) Convection

Explanation:

In the ocean, convection results in the continuous circulation of ocean water on a global scale. It occurs when the surface waters are cooled. This results in an increase in the density of the water on the surface and forces it to descend. Since intense cooling is necessary to cause oceanic convection, this process occurs mainly in the polar regions and is not as easily observed as that which occurs in the atmosphere in the tropical regions.
