Data for the annual production of calcium carbonate are not readily available. Approximately 1 billion tonnes of its two principal ores, limestone and dolomite, are mined annually in the US. Given the relative amounts of lime that is used in different countries, an estimate of worldwide mining of calcium carbonate is 15 billion tonnes a year.
They pump hydrogen ions (H +) out of this space to produce more carbonate ions (CO 32-) ions that bond with (Ca 2+) ions to make calcium carbonate (CaCO 3) for their skeletons. Because there are more HCO 3- ions but fewer CO 32- ions in acidified seawater, the corals have to expend more energy to pump out H + ions from …

Abstract. Shallow, seaward portions of modern coral reefs produce about 4 kilograms of calcium carbonate per square meter per year, and protected areas produce about 0.8 kilogram per square meter per year. The difference is probably largely a function of water motion. The more rapid rate, equivalent to a maximum vertical accretion of 3 to 5 ...
