As global
warming affects the earth and ocean, the retreat of the sea ice means there won't be as much cold, dense
water, generated through a process known as
oceanic convection, created to flow south and feed the Gulf Stream.

oceanic interior, but since the trades advect the surface
waters westward, the upper layer of
warm sea
water is deeper in the west than in the east.
An abrupt
warming of
oceanic intermediate
waters could have initiated the thermal destabilization of sediment - hosted methane gas hydrates and potentially triggered sediment slumps and slides.

It is possible that Lyman is measuring a transfer of
oceanic heat from
warm waters to cool
waters through circulation changes than increased retention of solar energies?
Ocean serves as the memory whereby slow
oceanic Rossby waves and Kelvin waves propagate through the basin and affect the depth of the
oceanic surface layer of
warm water.
This is what happens in our model events pictured above: during cold phases in Greenland,
oceanic convection only occurs in latitudes well south of Greenland, but during a DO event convection shifts into the Greenland - Norwegian seas and
warm and saline Atlantic
waters push northward.
The study found that major hot spots for large marine predators are the California Current, which flows south along the U.S. west coast, and a trans -
oceanic migration highway called the North Pacific Transition Zone, which connects the western and eastern Pacific on the boundary between cold sub-arctic
water and
warmer subtropical
water — about halfway between Hawaii and Alaska.
This rise may have been eustatically controlled, possibly through a combination of thermal expansion of the
oceanic water column and melting of unknown sources of high - altitude or polar ice caps in response to global
warming.»
There is absolutely no reason to believe that this effect will do anything but get stronger from here on as the vast «crops» of
oceanic bacteria adapt to both
warmer ocean
waters and increased CO2 and nutrient levels and simply increasingly cool the global atmospheric climate simply by «growing faster»!
A strengthening ACC created a barrier inhibiting intrusions of
warm tropical
waters and minimizing both
oceanic and atmospheric heat transport resulting in the Refrigerator Effect.
Likewise the
oceanic mixed layer (the top one or two hundred meters of
water that is roughly constant in temperature compared to deeper down, due to wave - induced mixing in that layer) delays global
warming but does not stop it.
Its cause was
oceanic —
warm water carried across the Pacific by the super El Nino.
Causality is always tricky to assign in cases such as this one, since it's entirely possible that the ridging itself has led to
warm surface
water though decreased
oceanic mixing by wind and unusually high air temperatures.
The persistent upwelling of cold
water in the eastern tropical Pacific would have reduced cloud cover there, via reduced
oceanic evaporation, and thus allowed more of the sun's energy to enter the tropical ocean - this would have aided the ocean
warming process, as generally the case when the tropical ocean is cooler - than - normal.
Di Lorenzo et al. (2010) presents evidence of the unique impacts of Central Pacific (CPAC) El Niño events (i.e., El Niño episodes when the
warmest waters are located in the central tropical Pacific) on the Northern Hemisphere atmospheric and
oceanic circulation on interannual and decadal time scales.
Most of the actual
warming of
oceanic water comes from its absorption of visible light and UV and short wavelength IR at depth.
Our findings require a reassessment of the role of the Southern Ocean in determining the impact of atmospheric
warming on deep
oceanic waters.
Recent observational surveys have shown significant
oceanic bottom -
water warming.
During the six years of in - situ measurements, an
oceanic warming of 0.77 ± 0.11 Wm − 2 occurred in the upper 2000m depth of the
water column.
Figure 2 - B suggests that since 1979 there has been a jump of at most 0.3 °C during the great El Niño of 1997 - 98; (see figure 15 - A showing that El Niño paces the global temperatures as the
water of the
warm pool is redistributed to the
oceanic surface layer at higher latitudes).
At the same time, they point towards below normal ice extent in the Barents / Kara Sea, also compared to the record minimum in 2007, which they see coupled to
oceanic processes and promoting further
warming of surface
waters in the region.
Because of the accumulation of greenhouse gases in the atmosphere, the
oceanic «conveyor belt» that sends
warmer waters into the North Atlantic could abruptly shut down.
Global
warming could have especially strong impacts on the regions of
oceanic subpolar fronts, where the temperature increase in deep
water could lead to a substantial redistribution of pelagic and benthic communities, including commercially important fish species.
Upwelling of deep
oceanic waters along continental margins release large concentrations of CO2, as the rising
water warms and CO2 stability in
water diminishes releasing the gas back into the atmosphere.
As Arctic Ice decreases it exposes more
warm water from the tropics carried up by the
oceanic conveyor belt.
This implies that hurricane intensity increase due to a possible global
warming associated with increased CO2 is considerably smaller than that expected from
warming of the
oceanic waters alone.»
The temperature regime is very different to onshore permafrost and deeper
oceanic hydrates, and sensitive to
warming of the shallow coastal
waters over the ESAS.
