«As a result, ocean waters deeper than 500 meters (about 1,600 feet) have a large but still unrealized absorption capacity... As emissions slow in the future, the oceans will continue to absorb excess CO2... into ever - deeper layers... eventually, 50 to 80 percent of CO2 cumulative emissions will likely reside in the oceans»

Warming is widespread over the upper layer of the ocean (500 meters or so), and this may change normal ocean circulation patterns, with unforeseen consequences.

That's because the mixed layer (surface to 300 meters) is only about 10 % of the ocean volume.

They have incorporated new models of ocean circulation, focused in particular on the layer 200 to 500 meters (650 to 1,650 feet) beneath the surface.

Recently there have been some widespread misconceptions about heat accumulation in the oceans, particularly in the deeper layers below 700 meters.

It may very well raise the upper ocean mixed layer (~ 300 meters) more or less than that depending on the how fast energy in the mixed layer equalizes with the abyss.

Shaviv has one chart in his paper that show «Maximum annual depth (in meters) of the mixed layer based on the ocean temperature data set of Levitus and Boyer.»

This results in what's known as the cool skin layer of the ocean which is the topmost 1 millimeter being about 1C cooler than the bulk mixed layer (~ 300 meters) below it.

Because 5 gazillion Joules is a 0.2 C mixed layer (top ~ 300 meters) surface temperature rise (Figure 10, Historical ocean heat content calculated from HadSST and OHC, Levitus, 2009).

The oceans are really big, yet the presence of currents and layers at different temperatures means temperatures can be quite different in waters just a few hundred meters apart.

Of the 24,982 Lagrangian particles injected into the Southern Ocean at a depth of 1000 meters, 66 % were advected (in an average of 37.8 years) above a designated mixed layer depth boundary that the researchers deemed to be «a key boundary to separate failed and successful carbon sequestration.»

The Atlantic annual formation of deep water has the volume of about one meter layer of surface water of the oceans based on a rapid calculation I made.

Once the CO2 concentration of the upper ocean is depleted by growth and sinking of phytoplankton, the timescale for gas exchange with the atmosphere is about a year for a one - hundred meter ocean mixed layer, typical of the tropics.

According to NODC data the 0 - 2000 meter layer of Arctic ocean is cooling — which means there is less energy in the system.

I assume they got the value for the observed 0.1 °C over 42 years in that 700 - meter layer of ocean from a legitimate source.

- and MOST IMPORTANTLY, the maths to show how an increase in temperature of the vents (a tiny percentage of the ocean floor), converts to the Joules required to warm the mass of the 700-2000 meter layers of water GLOBALLY.

- Jo]- and MOST IMPORTANTLY, the maths to show how an increase in temperature of the vents (a tiny percentage of the ocean floor), converts to the Joules required to warm the mass of the 700-2000 meter layers of water GLOBALLY.

-- and MOST IMPORTANTLY, the maths to show how an increase in temperature of the vents (a tiny percentage of the ocean floor), converts to the Joules required to warm the mass of the 700-2000 meter layers of water GLOBALLY.

One effect among many is to reduce the temperature gradient within the skin layer of the ocean and hence reduce the rate of cooling of the upper mixed layer (the first few meters of which are warmed by the Sun) to the atmosphere and also, radiatively, through the atmospheric infrared window, directly to space.

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.

For example, Spencer has previously used a mixed ocean layer depth of 700 meters, because although this is physically unjustifiable, it allowed his model to fit the data with a low climate sensitivity.

When the MJO inhibits convection, light winds and clear skies allow the upper few meters of the ocean to warm and separate into stable layers stratified by temperature and salinity.

We also know that the heat capacity of seawater is so much greater than that of air that the top three meters of global ocean have the same capacity as the entire planetary atmosphere, and that the «mixing layer» being discussed is at least thirty times that depth.

It's important to point out that overall deep - ocean heating (0 - 2,000 meters) shows no sign of a slow down in recent years, though shallower layers (0 - 300 meters and 0 - 700 meters) do.

Researchers of the new study appeared to have found an explanation to this after finding that a specific layer between 100 and 300 meters below the surface of the waters of the Indian and Pacific oceans has been accumulating more heat than previously known.

As illustrated in Figure 1 above, the study divides ocean warming into three layers for comparison — the uppermost 300 meters (grey), 700 meters (blue), and the full ocean depth (violet).

It doesn't even appear to be enough to raise the temperature of the shallow surface layer by more than a fraction of a degree to say nothing of imparting any significant warmth to the other 90 % of the volume of the global ocean below the thermocline (400 + meters deep).

And nobody really yet understands the complexity of heat exchange between the mixed layer and thermocline nor between the end of thermocline and the vast bulk of the ocean (90 % of its volume) below the 1000 meter extent of the thermocline.

The well mixed surface layer is only 300 meters deep and represents only 10 % the thermal mass of the ocean.

For the record, more than half (52 %) of ocean waters lie below the 2000 meter depth, so calling the 500 - 2,000 meter layer the «deep ocean» is still quite relative.

Also see this graphic that shows the ocean heating in two layers, 0 - 700 meters and 700-2000 meters deep.
