WebSabine et al ., (2004) reported that a third of the anthropogenic carbon dioxide produced since pre-industrial times has been absorbed by the ocean, resulting in a decrease in pH of approximately 0.1 units. The pH is a logarithmic scale and this equates to an increase in acidity of approximately 30%. WebApr 15, 2008 · The acids lower seawater’s pH and strip it of carbonate ions. (Ultimately, so does ammonia, a base, which is converted to nitrates and nitric acid.) That hampers the ability of marine organisms—such as sea urchins, shellfish, corals, and certain types of plankton—to harness calcium carbonate to make hard outer shells or “exoskeletons.”
