Coral reefs are vital to the long-term viability of tropical coastal societies, providing economic, recreational, and aesthetic value upon which coastal communities thrive. Coral reefs provide nurseries and habitat for commercially important fish species, production of sand for beaches, and protection from storm waves. These coral reef resources depend on the ability of calcifying organisms to build the three-dimensional structure of a reef as they produce their calcium carbonate skeletons. Ocean acidification can cause a decrease in calcification and dissolution of carbonate sediments that may lead to erosion of reef structure and increase the vulnerability of coastal communities to storms and seafloor habitat loss. Researchers at the USGS St. Petersburg Science Center are working with various government and academic partners to develop comprehensive records of modern and historical coral reef growth and calcification rates relative to changing seawater chemistry resulting from ocean acidification. These records will provide the foundation for predicting future impacts of ocean acidification and sea-level rise on coral reef growth.
