Deeper water remained unusually warm, especially in the northern part of the California Current.
Arrays monitor circulating currents in the Atlantic Ocean, in which warm shallow waters move north (red), while cold deep waters move south (blue).
The wind changes were found to be heaving warm currents from deeper waters up into a zone where the Antarctic ice sheet is vulnerable to melt and crumble from beneath — the area where towers of ice sit atop submerged ground.
With the removal of the warm surface waters, an upwelling current is created in the east Pacific Ocean, bringing cold water up from deeper levels.
Since deeper waters will be warmer, there is a possible link to the global ocean circulating currents that results in warmer water in polar regions.

A lot of reseach energy is being devoted to the study of Methane Clathrates — a huge source of greenhouse gases which could be released from the ocean if the thermocline (the buoyant stable layer of warm water which overlies the near - freezing deep ocean) dropped in depth considerably (due to GHG warming), or especially if the deep ocean waters were warmed by very, very extreme changes from the current climate, such that deep water temperatures no longer hovered within 4C of freezing, but warmed to something like 18C.
The surface heat capacity C (j = 0) was set to the equivalent of a global layer of water 50 m deep (which would be a layer ~ 70 m thick over the oceans) plus 70 % of the atmosphere, the latent heat of vaporization corresponding to a 20 % increase in water vapor per 3 K warming (linearized for current conditions), and a little land surface; expressed as W * yr per m ^ 2 * K (a convenient unit), I got about 7.093.
(In real life I understand that mixing is the main agent of deeper warming in the ocean due to winds, currents, etc.) Only the top skin of water heats up and therefore lower warming must be by diffusion, or are convection cells within the water inevitable?
Conceptually, it's hard to see how the Gulf Stream western boundary current could be weakened by conditions around Greenland; this is a fluid dynamics system, not a mechanical «belt»; a backup due to less deep water formation should have little effect on the physics of the gyre and the formation of the western boundary current, and it also seems the tropical warming and the resulting equator - to - pole heat transport are the drivers — but perhaps modulation by jet stream meandering is playing some role in the cooling?
I recall mention that Katrina was unusual because while crossing the Gulf «Ring Current» the deeper water pulled up by the hurricane was almost as warm as the sea surface, so the deeper water fed almost as much heat energy into the storm as the surface.
Surface temperature is an imperfect gauge of whether the earth has been warmed by an imbalance between incoming radiation from the sun, and outgoing radiation, because of the role of ocean currents in the distribution of heat between deeper and surface waters.
Either a big chunk of ice has been melting extraordinarily fast — which would cool the surrounding air — or somehow ocean currents would have changed in a way that favoured more rapid warming of deep water.
Most of the deep ocean warming is occurring in the subtropical ocean gyres - vast rotating masses of water in each ocean basin where near - surface currents converge and are forced downward into the ocean interior.
Warm Atlantic waters that don't enter the Irminger Current, continue deeper into the Arctic, mostly via the Barents Sea.
Turbulent deep ocean flows surface and set up wind and current responses that again extend the cold tongue and piles warm surface water up against Australia and Indonesia.
The influx could slow down or shut off the North Atlantic Deep Water (NADW) formation, the driving factor behind the conveyor belt current known as thermohaline circulation, which brings large amounts of warm water to the North Atlantic reWater (NADW) formation, the driving factor behind the conveyor belt current known as thermohaline circulation, which brings large amounts of warm water to the North Atlantic rewater to the North Atlantic region.
During the warm period, faster currents cause more tropical water to travel to the North Atlantic, warming both the surface and the deep water.
Two items: the first, the layered Ocean currents, fresh water on top, then the warmer but saltier layer and finally the deep bottom layer.
Atlantic Meridional Overturning Circulation A major current in the Atlantic Ocean, characterized by a northward flow of warm, salty water in the upper layers of the Atlantic, and a southward flow of colder water in the deep Atlantic.
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.
8 global circulation of deep ocean currents transports warm water to colder areas & cold water to warmer areas efficient heat - transport system drives Earth's climate
Current global climate models suggest that the water vapor feedback to global warming due to carbon dioxide increases is weak but these models do not fully resolve the tropopause or the cold point, nor do they completely represent the QBO [Quasi Biennial Oscillation], deep convective transport and its linkages to SSTs, or the impact of aerosol heating on water input to the stratosphere.
In the Atlantic Ocean, the current known as the Atlantic Meridional Overturning Circulation (AMOC) ferries warm surface waters northward — where the heat is released into the atmosphere — and carries cold water south in the deeper ocean layers, according to the National Oceanic and Atmospheric Administration.
The ocean waters of the deep circumpolar current that swirl around the continent have been getting measurably warmer and nearer the ocean surface over the last 40 years, [continue reading...]
Due to both bottom - boundary layer friction and interior adjustment, this coastal current anomaly facilitates the movement of warmer deep water upward onto the continental shelf and toward the coast (see Figure).
Note the temporary decrease in magnitude of the cold wake in one area behind the storm, indicative of the passage of the storm over a region containing the deep warm water of the Gulf of Mexico Loop Current.
The effects of this marked shift in westerly winds are already being seen today, triggering warm and salty water to be drawn up from the deep ocean, melting large sections of the Antarctic ice sheet with unknown consequences for future sea level rise while the ability of the Antarctic Circumpolar Current to soak up heat and carbon from the atmosphere remains deeply uncertain.
During Katrina and Rita, deep warm water in the Loop Current and within a Loop Current eddy was located under the storm tracks, which helped these storms to reach Category 5 intensity over the Gulf of Mexico.
«The top of the glacier is melting away as a result of decades of steadily increasing air temperatures, while its underside is compromised by currents carrying warmer ocean water, and the glacier is now breaking away into bits and pieces and retreating into deeper ground.»
Around 55 million years ago, an abrupt global warming event triggered a highly corrosive deep - water current to flow through the North Atlantic Ocean.
To this extent, the majority opinion of global warming is «water sloshing in a very shallow pan» as the New York Times» Andrew Revkin likes to say — it bounces around, reflecting current events, and generally isn't moored in deep beliefs one way or the other.
«Obviously the hotter water deep under the ice at the poles did not get any heat from the sun to be warmer and does not all have tropical water currents heating it, so where does the deep water get its heat from to stop from freezing.»
Being denser than warm water it then sank and flowed out along the bottom of the ocean in deep ocean currents, eventually filling the depths of the ocean basins around the world.
