How could this process increase CO2 fixation efficiency?

16 April 2015 1 8K Report

as we know calcite deposition could increase CO2 fixation efficiency for 1.5–2.5 folds at various input CO2 concentration

Hamida Darwish

The thick calcite layer can absorb the carbon dioxide

because the important factor regarding the precipitation of calcium carbonate in the oceans is the Carbonate Compensation Depth (CCD). The reaction:

Ca2++ 2HCO3– = CaCO3 + CO2 + H2O
