Ocean acidification could have broad effects on marine ecosystems
Date:12/17/2008

SAN FRANCISCO, CA--Concern about increasing ocean acidification has often focused on its potential effects on coral reefs, but broader disruptions of biological processes in the oceans may be more significant, according to Donald Potts, a professor of ecology and evolutionary biology at the University of California, Santa Cruz, and an expert in coral reef ecology and marine biodiversity.

Potts will give an invited talk on "Geobiological Responses to Ocean Acidification" at the Fall Meeting of the American Geophysical Union (AGU) in San Francisco on Wednesday, December 17.

Ocean acidification is one of the side effects of the rising concentration of carbon dioxide in Earth's atmosphere due to the burning of fossil fuels. The oceans can absorb enormous amounts of carbon dioxide from the atmosphere, but as the gas dissolves it makes the water more acidic. Increasing acidity can make life difficult for corals and other marine organisms that build shells and skeletons out of calcium carbonate.

Scientists fear that acidification will slow the growth of these organisms and cause calcium carbonate structures to dissolve. Potts agrees that dissolving shells will certainly be a problem for many marine organisms, but he thinks the disruptions will run much deeper.

"It's not just a question of coral reefs, and it's not just a question of calcification," he said. "What we are potentially looking at are disruptions of developmental processes and of populations and communities on many scales."

The term "acidification" refers to a slight lowering of the pH of ocean water, pushing it closer to the acidic end of the scale, although it is still slightly alkaline. A small decrease in pH affects the chemical equilibrium of ocean water, reducing the availability of carbonate ions needed by a wide range of organisms to build and maintain structures of calcium carbonate.
