Sentences with phrase «from deep ocean layers»

Either this is a truism (the sun must be heating the ocean surface first) or it is meant to take into account the complex circulations that occur in the ocean, like the Gulf Stream's involvement in a vertical rise of waters from deep ocean layers in one region and sinking of the cooled surface waters as the stream reaches its northern limit.

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.
In colder oceans, the separating layer (thermocline) does not form, or only for parts of the year, so phytoplankton at the top receives nutrients from the deeper sea and provides oxygen for the the upper and deeper layers (as well as nutrients, when phytoplankton decomposes).
This suggestion of an accelerated warming in a deep layer of the ocean has been suggested mostly on the basis of results from reanalyses of different types (that is, numerical simulations of the ocean and atmosphere that are forced to fit observations in some manner).

Another contributor is changes in ocean circulation which cause less heat is transported upwards from the deeper, warmer layer.
As discussed in the following section, the absence of significant warming in the Circumpolar Ocean of the Southern hemisphere is attributable mainly to the large thermal inertia of the ocean, which results from very effective mixing between the surface layer and the deeper layers of ocean in this reOcean of the Southern hemisphere is attributable mainly to the large thermal inertia of the ocean, which results from very effective mixing between the surface layer and the deeper layers of ocean in this reocean, which results from very effective mixing between the surface layer and the deeper layers of ocean in this reocean in this region.
With the temperature of the deep oceans explained, all the sun is doing is warm the surface layer from ~ 275K to ~ 290K.
To enjoy getting into those claims you would have to consider the impacts of differing rates of advection in the different ocean and atmospheric layers from the stratopause to the deep oceans.
upwelling wind blows, moves water away, causes new water to rise up to replace it brings up tiny ocean organisms, minerals, and other nutrients from the deeper layers of the water.
brings up tiny ocean organisms, minerals, and other nutrients from the deeper layers of the water.
As there is no differentiation in type for the inflows and outflows, also 22 % of the red CO2 is exchanged by natural, colourless CO2, from the deep oceans (we forget for a moment that some of it returns in another season from the ocean surface layer and vegetation decay).
When the ocean surface is cooler, warmth is taken from the surface into deeper ocean layers that «do not emit heat out of the planet».
rw (05:22:03): «The motions of the massive oceans where heat is moved between deep layers and the surface provides variability on time scales from years to centuries.
So we have a surface layer (100 - 200m) warmed from above, deep oceans being their cold selves, and in between the thermocline, the transition from warm surface to cold deep ocean, warmed by conduction from the surface layer above.
I haven't seen any process that can transport large amounts of heat from the surface layer to the DEEP ocean.
Even though there are temperature layers in the ocean, which we used to hide from sonar, the deeper we went, the colder the water got.
So the temperature of the deep oceans (presently ~ 275K) is set by heat from inside the earth before the sun starts warming the surface layer.
The motions of the massive oceans where heat is moved between deep layers and the surface provides variability on time scales from years to centuries.
However, I have repeatedly pointed out that the opposite is also possible because the deep ocean waters now returning to ocean surface could be altering the pH of the ocean surface layer with resulting release of CO2 from the ocean surface layer.
This fresh water, together with melt ‐ water from the melting ice pack in summer forms a permanent superficial layer (usually about 200m deep) of low salinity over the entire Arctic Ocean, without which much less seasonal ice would form.
Right: global ocean heat - content (HC) decadal trends (1023 Joules per decade) for the upper ocean (surface to 300 meters) and two deeper ocean layers (300 to 750 meters and 750 meters to the ocean floor), with error bars defined as + / - one standard error x1.86 to be consistent with a 5 % significance level from a one - sided Student t - test.
On an earlier thread I made a back - of - envelope calculation that, for the deep ocean to «suck» all the heat down from the surface, so that the sea surface layer and troposphere were nowhere more than 3C, the mean temperature of the deep ocean would need to increase only 0.4 C. Maybe someone could check this.
Nor can one be confident that the contribution of subsea volcanic variability to deep - ocean temperature change is negligible in comparison with that from the atmosphere, particularly when the relative densities of the two media and the distance of the benthic layers from the atmosphere are taken into account.
The existence of that cooler layer is evidence that the rate of evaporation is the primary influence on variability in the rate of ocean energy loss (apart from internal ocean circulation variability which is not relevant here) and it follows that more evaporation for the same rate of conduction and radiation (from a stable temperature differential) will send that cooler layer deeper and / or intensify the temperature differential between it and the ocean bulk below.
Of course, if the air were to be warmer than the ocean surface then evaporation would take the extra energy required from the air rather than the water and that 1 mm deep layer (0.3 C cooler than the ocean bulk) would rise to the surface and dissipate but that doesn't happen often or for long.
Since the skin layer usually needs to tap into solar energy deposited deeper in the ocean to make up its deficit, the skin layer will obviously make use of any extra DLR from an enhanced greenhouse effect.
