Coastal regions around the United States respond differently to ocean acidification, a large-scale study finds. In the new study, scientists from 11 U.S. institutions measured levels of carbon dioxide and other forms of carbon in waters off the East Coast and the Gulf of Mexico. If the same amount of carbon dioxide entered both the Gulf of Maine and the Gulf of Mexico, it would have a greater effect on the Gulf of Maine's ecosystem, the scientists found. "Before now, we haven't had a very clear picture of acidification status on the East Coast of the U.S.," lead study author Zhaohui 'Aleck' Wang, a chemical oceanographer at Woods Hole Oceanographic Institution (WHOI), said in a statement. "It's important that we start to understand it, because [an] increase in ocean acidity could deeply affect marine life along the coast and has important implications for people who rely on aquaculture and fisheries," Wang said. Coastal ocean acidification occurs when excess carbon dioxide is absorbed by, washes into or is produced in coastal oceans, triggering chemical reactions that make the water more acidic. Species like oysters, snails and coral are disproportionally affected, because they cannot form their protective shells in highly acidic conditions. http://news.yahoo.com/ocean-acidification-affects-northeastern-us-coasts-more-232739417.html
