What role do waves play in vertical circulation? What causes deep circulation of surface water? What factors lead to downwelling at high latitudes?

What role do waves play in vertical circulation? What causes deep circulation of surface water? What factors lead to downwelling at high latitudes? Why is deep ocean water at the equator cold and well-oxygenated? By what processes does this water reach the ocean bottom? Explain the depth of the oxygen minimum zone (use a graph).
