Mitigating the atmospheric CO2 increase and ocean acidification …
[1] The feasibility of enhancing the absorption of CO 2 from the atmosphere by adding calcium carbonate (CaCO 3) powder to the ocean and of partially reversing the acidification of the ocean and the decrease in calcite supersaturation resulting from the absorption of anthropogenic CO 2 is investigated. CaCO 3 could be added to the surface …Web
