OCEAN ACIDIFICATION or acid sea. It happened because of the amount of carbon dioxide increases. To dissolve in seawater. The carbon dioxide dissolves into the water, causing the pH value changes. The original seawater acidity - alkalinity or pH of about 8 to 8.1 or slightly to the slightly alkaline condition. But over time ago when the amount of carbon dioxide in the atmosphere of the Yaga. Prof. rise quickly into the sea, making the acidity in the sea change from the original is toward slightly alkaline. It turns more acidic. The sea has become a phenomenon 'Sea of acid' in the end because typically carbon dioxide is absorbed in water at sea. It is normal carbon cycle. But with fuel Falls City every day, it's more than cyclical balance immediately.
