The research published in Nature Communications found that in the past, when ocean temperatures around Antarctica became more layered - with a warm layer of water below a cold surface layer - ice sheets and glaciers melted much faster than when the cool and warm layers mixed more easily.

Melting sea ice will mean ocean currents can carry warmer water and nutrients into Arctic water, taking fish further north and potentially allowing them to mix between oceans.

The warming of the oceans by sunlight, makes the daytime surface waters more bouyant than the cooler waters below and this leads to stratification - a situation where the warmer water floats atop cooler waters underneath, and is less inclined to mix.

The Channel is an oceanographic transition zone where the cold waters north of Point Conception mix with the warm waters of Southern California, resulting in a complex system of water currents and a diversity of northern and southern ocean species.

The abundant waters off the coast of Cabo San Lucas — located at the southern tip of the Baja Peninsula, where the calm and warm waters of the Sea of Cortez mixes with the unfathomable cool currents of the Pacific Ocean — offer the ideal conditions for plenty of sport - fish species, including (among others) Rooster Fish, Mahi Mahi (known locally as Dorado), varieties of Tuna, Sharks, Jacks, Groupers, and Billfish such as Sailfish, Swordfish, Black Marlin, Blue Marlin and Striped Marlin.

The picture I gave neglects the effect of ocean dynamics — cooling by upwelled water entering the mixed layer and warming by imported warm water from the side.

You'll find, just as examples: ``... another — possibly substantial — source of energy for mixing that's generated in the ocean where cold, heavy water collides with warm, light water.

(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?

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?

The ocean's surface begins to warm, but before it can heat up much, the surface water is mixed down and replaced by colder water from below.

eadler2 January 10, 2015 at 5:54 pm ... When ocean surface temperatures cool, due to a La Nina, the warmer surface water is mixed deeper into the ocean and cooler ocean water flows along the surface of the Pacific.

When ocean surface temperatures cool, due to a La Nina, the warmer surface water is mixed deeper into the ocean and cooler ocean water flows along the surface of the Pacific.

Due to the predominance of La Nina's in the last 15 years, the warmer surface water has been mixed into the deeper ocean.

If there's no mixing lower (effective diffusivity = 0) that extra energy only has to warm up a volume of water 1/10 as large as the entire ocean.

Climate Alchemy and probably most scientists not taught chemical thermodynamics don't realise that the main heat transfer term in the oceans is the partial molar enthalpy transferred when the fresh, cold water sinking from melting ice in the Antarctic and Arctic summers is made more saline when it mixes with the warmer, more saline surface water for which solar energy has partially unmixed the ions.

The main mechanism for wind - driven mixing into the deep ocean (down to around 2000 metres) is via convergence of warm tropical surface water in the subtropical ocean gyres.

The paper discusses that melting ice will decrease the salinity of the ocean waters around Antarctica, which will cause decreased mixing with the relatively warmer deep ocean waters, reducing sea surface temperatures, causing more sea ice to form.

It can go through all sorts of transient fluctuations as the ocean mixes deeper colder water and warmer surface water.

«The short answer is that, during El Nino, there is an average decrease in the vertical overturning and mixing of cold, deep ocean waters with solar - heated warm surface waters.»

Nevertheless that cool ocean surface is absorbing solar energy and must warm, whilst the process of sweeping the warm waters westward by the SE Trades continues then the heat input with be masked / mixed into waters below.

``... mixing of cold, deep ocean waters with solar - heated warm surface waters.»

That will vary according to the ocean temperature gradient in as much water is not at all well mixed and so some strata will be warm whilst other parts will be cool.

WHEN the skin layer is warmer than the water below (and not mixed by the wind), there is no obvious mechanism (other than very slow conduction) for AGG - enhanced DLR to penetrate the ocean.

Only approximately 15 percent of that decline can be attributed to a warmer mixed - layer, with the remainder being «consistent with an overall decrease in the exchange between surface waters and the ocean interior» (Helm et al., 2011).

They report in the journal Science that a succession of aerial surveys combined with multiple satellite observations has established that the base of the glacier is being eroded rapidly by a mix of warmer ocean water and increasing amounts of meltwater from the surface of the Greenland ice sheet.

It's even possible that that the Triple R played a role in sustaining itself by reducing North Pacific storm activity and preventing vertical mixing of cooler sub-surface ocean water, culminating in a self - reinforcing feedback loop by which atmospheric ridging led to warm SSTs, which in turn led to more ridging, and so on.

Moreover, the warm «Blob» in the North Pacific essentially disappears in model forecasts later this winter, likely a product of numerous storm systems bringing vigorous vertical mixing of the ocean and drawing up cooler water from beneath.

On the contrary, whatever warm, hypersaline water sinks below the surface because of its great density is mixed relatively quickly by winds into the upper layer of the ocean, where it transfers its heat to colder parcels by conduction.

Furthermore, in the absence of such warming, ocean mixing would normally be expected to be constantly refreshing the water at the ocean's surface, the place where it meets with air and dissolves CO2.

If the other processes that warm abyssal waters (mixing and geothermal heating) have not changed, then this change could explain the abyssal ocean warming that we are observing.

How could it happen that radiative heat is causing warming of the ocean depths without warming the surface — especially when water is opaque to IR and the transfer of heat would have to involve mixing.

That warming extends the 50 m or so to the seabed because we are dealing with only a polar surface water layer here (over the shelves the Arctic Ocean structure is one - layer rather than three layers) and the surface warming is mixed down by wave - induced mixing because the extensive open water permits large fetches.

Thus, the static stability of the near - surface water increases and the convective mixing of cold surface water with the relatively warm subsurface water is reduced, thereby contributing to the reduction of sea surface temperature in the Circumpolar Ocean.
