What is the rate of ocean heat dispersion and the mechanism(s)?

Let's assume that energy enters the surface and surface layers of the ocean (for this question the method of heating is irrelevant). If we consider only the vertical movement of heat energy in the various layers of the oceans, how long does it take for this energy to be dispersed or transported to depth (and... show more Let's assume that energy enters the surface and surface layers of the ocean (for this question the method of heating is irrelevant).

If we consider only the vertical movement of heat energy in the various layers of the oceans, how long does it take for this energy to be dispersed or transported to depth (and vice versa)?

For the second part, what is the mechanism for heat exchange between (or within) ocean layers: radiation, conduction or convection? If a combination, which is dominant? And what is the heat exchange rate for each?

@jim z: Convection is definitely an interesting case for the oceans. If you try to Google that you'll notice that when talking about ocean convection, the main mechanism is the northward travel of warm water losing heat up to Arctic latitudes and then sinking to start (or maintain) the deep ocean conveyor belt. So the main convective process is cold water sinking. Obviously, that cannot explain ocean heat content increasing at depths of 700m or 2000m.

We are being asked to believe that a warming atmosphere is warming the cool skin layer of the ocean to an extent that it is preventing heat flow out of the oceans and that this extra heat is somewhere in the deep ocean. That needs more explaining in my mind which is the purpose of my last two questions on this subject.
Update 2: ____________________________________________________________________ @virtualguy: "the process is dense water sinking, not cold water sinking." You must be cold as ice if you believe 4C (max density) is not cold. ;) Ekman transport and Coriolis apply to surface or near surface currents as are wind... show more ________________________________________...

Ekman transport and Coriolis apply to surface or near surface currents as are wind shear and Langmuir Circulations. Most action in the ocean happens in the top 100m except for thermohaline circulation. The biological aspect of vertical movement is interesting but I'm having trouble finding the depths for this or any relation to energy movement.

"The "more explanation" your mind requires is available in just about any physical oceanography text."

That is probably true and it's just as likely online as well. I have been looking yet haven't found satisfactory answers. Hence this question.
