For decades, research on climate variations in the Atlantic has focused almost exclusively on the role of ocean circulation as the main driver, specifically the Atlantic Meridional Overturning Circulation, which carries warm water north in the upper layers of the ocean and cold water south in lower layers like a large conveyor belt.

For each measurement, they lowered a marine snow catcher beneath the upper layer of the ocean to capture a water sample.

«More heat is trapped in the upper layers of the ocean, where it can be easily released back into the atmosphere,» Park said.

This means that an increase in temperature and the associated reorganization in ocean circulation, for instance, had less of an effect on the marine ecosystem's ability to absorb CO2 from the atmosphere and store it in the subsurface layers of the ocean.

The second standout feature is in the deeper layers of ocean.

As may be expected from the positions of ocean currents, most mixing in the upper layers of the ocean takes place on the western boundaries of ocean gyres where the current speeds are greatest.

It focuses on the layers of the ocean.

I think the part about differential warming of different layers of the ocean to be particularly clear and useful.

The standard assumption has been that, while heat is transferred rapidly into a relatively thin, well - mixed surface layer of the ocean (averaging about 70 m in depth), the transfer into the deeper waters is so slow that the atmospheric temperature reaches effective equilibrium with the mixed layer in a decade or so.

As you will know, heat passes from a hotter to a cooler body; and on the average, the surface layers of the oceans are cooler than the air above them (as anyone who has tried swimming in the North Sea on a sunny day in August will testify).

First, global mean surface temperature depends on the quantity of heat stored at the surface of the earth (earth, lower atmosphere, and the mixed layer of the oceans).

If somehow and I can't possibly imagine how, there was a huge increase in circulation between the surface and the deeper layers of the ocean, that would be disastrous for global temperatures but not upwards but downwards!

Relative to the entire depth, oceans are essentially both cooled and warmed from above, but within the upper layer of the ocean, it is often the case that the oceans are warmed from below and cooled from above.

It's what drives the atmospheric circulation and the ocean currents that mix the upper warm layers of the ocean with the deeper colder layers, and vice versa.

2) Heating up the 1 mm (or smaller) topmost layers of the ocean (the «skin») decreases the thermal gradient thus slowing the loss of heat from the ocean into the atmosphere.

If the surface layer of the ocean is not quickly exchanging energy with the troposphere, which it can do easily and quickly but retaining the energy, why is it not heating up far more rapidly, If you are saying it is getting rid of it to the deep oceans, how precisely is it doing this so quickly?

The mixed layer of the ocean is mixed (pretty much by definition) thus the net fluxes at the surface (latent heat, sensible heat, long wave up and down, short wave down) warm or cool the whole layer.
