As CaCO3 production uses up 2 moles of alkalinity per mole of DIC, a reduction in production would lead to a greater increase in surface water alkalinity than DIC; this, in turn, would result in a decrease in the Revelle factor of the surface ocean and a greater oceanic capacity to uptake atmospheric CO2. The Revelle factor, 11866

These organisms are made of calcium carbonate and when they die they get broken down. If they end up below a certain depth they will dissolve and add ions to the water. The area where this occurs is below the lysocline which is about 750-4,300 meters for calcite (SEPM, 2013). There are also plants and algae that produce carbonate.
