Transcript of Coral Reef Calcificatiion

Coral Reef Calcification How/why does calcification affect the reefs? What is calcification? Calcification is the process in which calcium salts build up in soft tissue, causing it to harden. Coral Reefs are made up of Calcium Carbonate (CaCO3). As the Sea Surface Temperature (SST) rises the calcification process is not able to keep up with the destruction of the reefs causing them to slowly disinegrate. Coral reef calcification is
predicted to decrease 20–60% by 2100 causing destruction to the reefs. 2HCO3- + Ca2+ CaCO3 + CO2 + H2O Bicarbonate (HCO3-) combines with calcium ions in the water to make calcium carbonate
(CaCO3, limestone). How does the decrease in calcification affect the world? We would lose 375 billion dollars of annual revenue
Reefs protect the coastlines of 109 countries
