As it happens, the perfect in vivo laboratory to study ocean acidification lies across the Pacific from Brainard’s office in Honolulu, Hawaii: it’s the U.S. Commonwealth of the Northern Marianas Islands, located north of Guam and south of Japan. The Marianas offer a unique set of pristine ecosystems living side by side with hydrothermal vents both deep and shallow, spewing gaseous and even liquid CO2 and SO2. Near one vent, the pH of the water is 1.
