By Miguel Rodriguez. What is a Coral Reef?. Coral reefs are diverse underwater ecosystems held together by calcium carbonate exoskeletons secreted by corals, which support and protect the coral polyps.. Acidification Tolerance of Aquatic Organisms . Analysis. Conclusion & Applications. Data & Observations. Introduction. Different species respond to low levels of pH differently: some of the test subjects were . For tens of millions of years, Earth's oceans have maintained a relatively stable acidity level. It's within this steady environment that the rich and varied web of life in today's seas has arisen and flourished. But research shows that this ancient balance is being undone by a recent and rapid drop in surface pH that could have devastating global consequences.. Damian C. Brady, Ph.D.. Ira C. Darling Marine Center. University of Maine. August 1. st. , 2014. The Potential Role of Water Quality Modeling in Coastal Acidification Management. Damian C. Brady, Ph.D.. Key understanding. Due to the use of unsustainable energy, ocean acidification is a rising problem for marine ecosystems. The high levels of pH (acidity) in the water alters the natural chemical bonding process in regards to the building of shells and exoskeletons of marine wildlife.
