Oolitic Aragonite is generated through the chemical fixation of Carbon Dioxide (CO2) to the naturally present Calcium (Ca) in the ocean’s water, which results in the precipitation of Calcium Carbonate (CaCO3). This process is fueled by the photosynthesis within the blooms of phytoplankton; picoplankton: specifically cyanobacteria and unicellular green algae as they drift across the warm water banks of the Bahamas. Cyanobacteria has a Carbon Dioxide Concentrating Mechanism (CCM); this is a biochemical system that allows the cells to raise the concentration of CO2 at the site of the carboxylating enzyme rubulose (RUBISCO) by up to 1,000 times the surrounding medium. In addition the cyanobacteria excretes organic polymeric substances to form extracellular formations. These Exopolymeric Substances (EPS) serve as a nucleation surface for mineralization, accelerating the calcium carbonate generation process. The combination of the CCM and the presence of the EPS within the surrounding medium of the warm shallow waters of the Bahamas which are already supersaturated with the element Ca++ and carbonate, Ca–3, ions (Ca++ concentrations are at over 10 millimolar) readily result in the phenomenon of "Whitings", cloudy precipitation of oolitic aragonite (CaCO3) with a unique crystal morphology. This process continually produces millions of tons per year of oolitic aragonite sand within the Bahamas.
