Transcript of Coral Reef Calcification

Coral Reef Calcification Research Goal What is coral reef calcification, and what impact does it have on us? Coral reef calcification is a process which allows the reefs of the world to grow. This process happens when Biocarbonate combines with calcium ions in the water to make Calcium Carbonate. The chemical equation for this process is as follows: 2HCO3- + Ca2+ ---> CaCO3 + CO2 + H2O. The product of this equation is Calcium Carbonate, whereas the reactants are Biocarbonate (HCO3-)and the calcium ions (Ca2+). Two Biocarbonates join together with a calcium ion and form the calcium substance that causes these reefs to multiply. The ideal situation for this to happen is a warm sea surface temperature, supersaturated seawater, and a natural foundation. Detailed Synthesis Real World Application Since coral reefs are one of the most diverse ecosystems and are home to more than 25% of all marine species, it is very good to hear that these calcified build-ups are creating growth. Reefs all around the world are attractting a lot of tourists and that brings in profit to those locations. These coral reefs are called the "Rainforest of the Ocean" and it would be a shame to see them gone.
