However, the
ocean is very strongly stratified, and the interaction with the bulk of the
deep cold water is very slow — it is generally the upper
ocean that determines the time scale for the transient warming we might expect.
However, there is also a huge reservoir of
cold water in the

Think of what would happen if you could pump
cold deep water up to the surface, increasing the air / sea temperature gradient and warming the
water; that would give you an anomalously large
ocean heat uptake.
IF cool
deep sea
water were mixed relentlessly with surface
water by some engineering method --(e.g. lots of wave operated pumps and 800m pipes) could that enouromous cool reservoir of
water a) mitigate the thermal expansion of the
oceans because of the differential in thermal expansion of
cold and warm
water, and b) cool the atmosphere enough to reduce the other wise expected effects of global warming?
I have to raise an objection to the phrase «the only region of the world that has defied global warming» — that might be neglecting a certain area in the Pacific where England 2014 has identified a very obvious point where the «Pacific conveyor» was bringing in the last decade up a lot of
cold water from the
deep ocean and has possibly played a major role in the specific trends for that period.
Even assuming that the dataset is comprehensive: Considering that the upper -
ocean cooling is seen mainly at 30N and 30S, another explanation for this cooling is increased
ocean — to — atmosphere heat transfer in these regions (possibly aided by hurricane - mixing of the upper
ocean layer, and advection of
deeper cold water as a result).
It's always worth remembering that the other end of the AMOC involves two main factors: (1) vorticity - mixing of heat from surface
waters into the
deep abyssal ocean (which decreases density causing the Atlantic Deep Water to start rising above the colder Antarctic Bottom Water) and (2) the wind - driven upwelling around the Antarctic Circumpolar Curr

Consenquently, the associated SST pattern is slightly cooler in the
deep convection upwelling regions of the Equitorial Pacific and the Indian
Ocean, strongly cooler in the nearest
deep convection source region of the South Atlantic near Africa and the Equator, warm over the bulk of the North Atlantic, strongly warmer where the gulf stream loses the largest portion of its heat near 50N 25W, and strongly cooler near 45N 45W, which turns out to be a back - eddy of the Gulf Stream with increased transport of
cold water from the north whenever the Gulf Stream is running quickly.
Marine biological activity then transfers a bit more C to the
deep ocean than
cold, upwelling
waters bring back up, such that the net sink to the
deep ocean is about 1.6 GtC / yr, and much slower permanent removal in sediments.
They then looked at the challenges that warmer
oceans delivered for crustaceans, molluscs, sponges,
deep sea invertebrates, the warm and
cold water corals that provide habitat for one - fourth of the
ocean's variety, the pelagic or surface - swimming fish, and the demersal or
deep - sea denizens that live longer, reproduce more slowly and are thus less likely to evolve and adapt to changing conditions.
The Atlantic overturning is driven by the differences in the density of the
ocean water: when the warm, lighter
water flows from south to north it becomes
colder, denser and heavier, making it sink
deeper and flow back southwards.
Ocean temperature change, however, reached a lower limit, probably because the freezing point of sea water put a restriction on how cold the deep ocean could

While such a «missing heat» explanation for a lack of recent warming [i.e., Trenberth's argument that just can not find it yet] is theoretically possible, I find it rather unsatisfying basing an unwavering belief in eventual catastrophic global warming on a
deep -
ocean mechanism so weak we can't even measure it [i.e., the
coldest deep ocean waters are actually warmer than they should be by thousandths of a degree]...
Now the researchers noticed that all of these flu pandemics started in the boreal spring or summer and were preceded by La Niñas — the phases in the El Niño Southern Oscillation (ENSO) that see large upwelling of
cold deep ocean water in the East Pacific, which is then spread out across much of the
ocean.
The resulting formation of Antarctic sea ice expelled
colder, salty
waters that filled the abyss and began cooling the
deep oceans.
Between 2 and 3 million years ago the cooling of the
deep oceans reached a tipping point, and modern upwelling regions ogf
cold deep water off the coast of Peru, California and the west coast of Africa were established.
The aragonite, a crystal form of calcium carbonate, formed by tiny organisms then become too corroded to survive in high - pressure or
cold waters including some parts of the shallow North Pacific, the southern
ocean and the
deepest waters of the
ocean.
