Researchers can study ocean acidification in the lab by rearing organisms (here, Lophelia deep-sea corals) in seawater with variable pH and measuring if they grow, eat, breathe, reproduce, or develop differently.

By pumping enormous test tubes that are 60-feet deep and hold almost 15,000 gallons of water with carbon dioxide to make the water inside more acidic, researchers can study how zooplankton, phytoplankton and other small organisms will adapt in the wild.
