The solubility pump is driven by the coincidence of two processes in the ocean : The solubility of carbon dioxide is a strong inverse function of seawater temperature (i.e. solubility is greater in cooler water) The thermohaline circulation is driven by the formation of deep water at high latitudes where seawater is usually cooler and denser

Three main processes (or pumps) that make up the marine carbon cycle bring atmospheric carbon dioxide (CO 2) into the ocean interior and distribute it through the oceans. These three pumps are: (1) the solubility pump, (2) the carbonate pump, and (3) the biological pump.

Originally formulated by Tsunogai et al. (1999), [1] the pump is believed to occur where the solubility and biological pumps interact with a local hydrography that feeds dense water from the shelf floor into sub-surface (at least subthermocline) waters in the neighbouring deep ocean.
Dissolved inorganic carbon is a key component of the biological pump, which is defined as the amount of biologically produced organic carbon flux from the upper ocean to the deep ocean. [6] Dissolved inorganic carbon in the form of carbon dioxide is fixed into organic carbon through photosynthesis.
Oceanic carbon naturally cycles between the surface and the deep via two "pumps" of similar scale. The "solubility" pump is driven by ocean circulation and the solubility of CO 2 in seawater. The "biological" pump is driven by phytoplankton and subsequent settling of detrital particles or dispersion of dissolved organic carbon.
Carbon dioxide forms carbonic acid when dissolved in water, so ocean acidification is a significant consequence of elevated carbon dioxide levels, and limits the rate at which it can be absorbed into the ocean (the solubility pump). A variety of different bases have been suggested that could neutralize the acid and thus increase CO 2 absorption.
