This can happen if something increases the amount of mixing between the (warm) shallow ocean and the (cold) deep ocean.

But seen the environmental global CRISIS of GLOBAL WARMING and its devastating climatological impact, I would recommend as an environmental policy - expert that Both NATURAL plankton will be bred in shallow waters as carbondioxide inhibitors in a large volume on the one hand and let nature goes its course in the seas and oceans so that sea - organisms / life - forms / mamals will not become extinct due to (for them) food poisoning.

Ocean waters around Antarctica have warmed steadily for the past 50 years, but in addition to that, the region's shallow seas are also heating up, more quickly than others.

Under the new slab - ocean approach, the LHF increase is weaker under warming, the Cu layer shallows (if the large - scale subsidence rate is kept fixed), and the inversion strengthens.

Due to the Antarctic Refrigerator Effect, the deep oceans continued to cool, and the thermocline that separates warm surface water from cooler deep waters became increasingly more shallow.

MA Rodger # 16 Yes, it's the fallacious argument that a mass can not warm a warmer mass, used in both atmosphere (radiation) and ocean comments (the fallacy that heat can not increase at depth with also increasing shallower, and this «heat gone forever» one).

Their scientific cruises on the shallow continental shelf occurred as sea ice in the Arctic Ocean was rapidly melting and as northern Siberia was earning the distinction — along with the North American Arctic and the western Antarctic Peninsula — of warming faster than any place on Earth.

I don't know about heat sloshed under the poles but I need a slosh of scotch heat after this; since you know Bob well you will know he has discussed a reemergence mechanism to explain how the ocean can put heat into the atmosphere in an El Nino year yet keep warming itself; and despite the fact that the oceans are a complex eddying mess the fact remains that AGW is a top down heater; if the oceans were going to be heated by AGW a shallow ocean would be heating; but it ain't:

When many modern families of animals developed in a hot greenhouse world in which a warm ocean and land filled most of earths surface with fertile shallow seas and vast tropical jungles.

O.T. but here's another paper for Kenneth to add to the ever growing pile of real research called «Enhanced CO2 uptake at a shallow Arctic Ocean seep field overwhelms the positive warming potential of emitted methane» and is available here http://www.pnas.org/content/114/21/5355.abstract.

If some of the ocean heat uptake during the last 20 years has shifted from the shallow and warm parts to the deeper and colder parts this would reduce the total thermal expansion even if the total heat flux into the oceans remained the same.

The first is salinity driven and carries mostly hot saline water down into the depths from shallow equatorial atolls warming the deep ocean.

47 Warm, shallow current Cold, salty, deep current Fig. 20 - 12, p. 476 Figure 20.12 Natural capital: a connected loop of shallow and deep ocean currents stores CO2 in the deep sea and transports warm and cool water to various parts of the eaWarm, shallow current Cold, salty, deep current Fig. 20 - 12, p. 476 Figure 20.12 Natural capital: a connected loop of shallow and deep ocean currents stores CO2 in the deep sea and transports warm and cool water to various parts of the eawarm and cool water to various parts of the earth.

Nuccitelli et al. (2012) considered the warming of the oceans (both shallow and deep), land, atmosphere, and ice, and showed that global warming has not slowed in recent years (Figure 3).

That the slowdown in surface warming has been concentrated in the ocean - surface (and shallow - ocean) temperatures has led a number of scientists (including the Met Office) to posit that the pause in ocean surface warming may be driven in part by increased heat uptake in the deep ocean.

However, it must be borne in mind that the MOC can also include shallower, wind - driven overturning cells such as occur in the upper ocean in the tropics and subtropics, in which warm (light) waters moving poleward are transformed to slightly denser waters and subducted equatorward at deeper levels.

It looks like the sub-sea permafrost is failing due to warmer ocean temperatures and allowing methane to escape; because the Siberian Sea is very shallow the methane isn't oxidized as it travels to the surface.

What are telling observations against the hypothesis of a largely internally driven imbalance are, on the one hand, the fact the sea level variations are relentlessly positive, irrespective the phase of the PDO, and, on the second hand, the fact that the rate of warming over land is larger than it is over sea (and also that the shallow (0 - 700m) ocean layer never actually cools).

However, there has been plenty of warming of the shallow oceans that could have been transferred to the deeper oceans.

In our case, the water is flowing into the tub faster than it's draining out - the shallow oceans are warming fast, as the figure above illustrates.

The Arctic Ocean may be a special case, because of the shallower stability zone due to the colder water column, and because warming is expected to be more intense in high latitudes.

I've often wondered at the fact that the deep ocean has been warming while the shallow ocean is cooling.

It's not clear boreal feedbacks are even necessary to lighting off tropical biomass (fire once again), but they'll certainly speed the process way up; if that does happen in turn we're on our way to a hyperthermal (with some lag since the oceans have to warm enough to trigger a self - sustaining loss of shallow methane hydrates).

They explain the lesser warming in the East Pacific Ocean, near South America, as being due to the fact this region is kept cool by upwelling, rising of deeper colder water to shallower depths.
