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

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.
These three pumps are: (1) the solubility pump, (2) the carbonate pump, and (3) the biological pump. The total active pool of carbon at the Earth's surface for durations of less than 10,000 years is roughly 40,000 gigatons C (Gt C, a gigaton is one billion tons, or the weight of approximately 6 million blue whales ), and about 95% (~38,000 Gt C ...

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.
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.
