Possible mechanisms include (iv) fertilization of phytoplankton growth in the Southern Ocean by increased deposition of iron - containing dust from the atmosphere after being carried by winds from colder, drier continental areas, and a subsequent redistribution of limiting nutrients; (v) an increase in the whole ocean nutrient content (e.g., through input of material exposed on shelves or nitrogen fixation); and (vi) an increase in the ratio between carbon and other nutrients assimilated in organic material, resulting in a higher carbon export per unit of limiting nutrient expoOcean by increased deposition of iron - containing dust from the atmosphere after being carried by winds from colder, drier continental areas, and a subsequent redistribution of limiting nutrients; (v) an increase in the whole ocean nutrient content (e.g., through input of material exposed on shelves or nitrogen fixation); and (vi) an increase in the ratio between carbon and other nutrients assimilated in organic material, resulting in a higher carbon export per unit of limiting nutrient expoocean nutrient content (e.g., through input of material exposed on shelves or nitrogen fixation); and (vi) an increase in the ratio between carbon and other nutrients assimilated in organic material, resulting in a higher carbon export per unit of limiting nutrient exported.

Proposed explanations for the discrepancy include ocean — atmosphere coupling that is too weak in models, insufficient energy cascades from smaller to larger spatial and temporal scales, or that global climate models do not consider slow climate feedbacks related to the carbon cycle or interactions between ice sheets and climate.

The airborne fraction of new carbon added to the system drifts down from 15 - 25 % after equilibration between the atmosphere and the ocean but before neutralization by the CaCO3 cycle and ultimate recovery by the silicate weathering CO2 thermostat.

Huge quantities of carbon are exchanged between the oceans, atmosphere, and biomass.

It plays a crucial role in the carbon cycle — the exchange of carbon dioxide between the atmosphere and the oceans — and in the buffering of blood and other bodily fluids.

The significance of these restraints should be considered by the deniers when they assert that the amount of carbon dioxide dissolved in the oceans is so large that exchanges between the ocean and the atmosphere dwarf human production.

Here we present a means to estimate this natural flux by a separation of oceanic carbon anomalies into those created by biogenic processes and those created by CO2 exchange between the ocean and atmosphere.

In between the atmosphere and what we release, there is the ocean which acts like a buffer or think a battery which first soaks up most of released carbon.

That 280 Gt of carbon has to go somewhere and will end up being divided between the atmosphere and oceans.

According to Wikipedia they explain the RE by saying: «If CO2 in the atmosphere is increased by one part per million, the CO2 in the ocean is increased by only a tenth of a part per million, because of the way that the carbon dioxide in the water is partitioned between carbonate ions and bicarbonate ions and free CO2.

The carbon cycle is the transfer of carbon between the Biosphere, Atmosphere, Ocean and Lithosphere 5.

In a previous post, Eli explored the rapid equilibrium between the three surface reservoirs for carbon dioxide, the atmosphere, the biosphere and the surface of the oceans, maybe to a depth of 1 km.

The correlation between rising levels of carbon dioxide in the atmosphere (red) with rising carbon dioxide levels (blue) and falling pH in the ocean (green).

Note that the gross amounts of carbon annually exchanged between the ocean and atmosphere, and between the land and atmosphere, represent a sizeable fraction of the atmospheric CO2 content and are many times larger than the total anthropogenic CO2 input.

QUOTE: «As shown on figure 17 - D the regions for absorption and out - gassing are separate; there is no «global» equilibrium between the atmosphere and the ocean; carbon absorbed tens of years ago at high latitudes is resurfacing in up - wellings; carbon absorbed by plants months to centuries ago is degassed by soils Sorry, there is a fundamental lack of knowledge of dynamic systems here: as long as the total of the CO2 influxes is the same as the total of the CO2 outfluxes, nothing happens in the atmosphere.

As shown on figure 17 - D the regions for absorption and out - gassing are separate; there is no «global» equilibrium between the atmosphere and the ocean; carbon absorbed tens of years ago at high latitudes is resurfacing in upwellings; carbon absorbed by plants months to centuries ago is degassed by soils.

Earth System Models are mathematical descriptions of the real world at the cutting edge of understanding how our planet works and the links between the main components of the oceans, vegetation, ice and desert, gases in the atmosphere, and the carbon cycle, as well as numerous other components.

Once CO2 has been emitted into the atmosphere, the carbon cycle will redistribute it between the atmosphere, oceans, and terrestrial biosphere, but it will not disappear from those systems for thousands of years.

Climate depends on a multitude of non-linear processes such as the transfer of carbon from the atmosphere to the oceans, the earth and plants, but the models used by the IPCC depend on many simplifying assumptions of linearity between causes and effects in order to make the computation feasible.

However, detailed climate projections carried out with Atmosphere - Ocean General Circulation Models (AOGCMs) have typically used a prescribed CO2 concentration scenario, neglecting two - way coupling between climate and the carbon cycle.
