Data from: Resistance of corals and coralline algae to ocean acidification: physiological control of calcification under natural pH variability
Associated Persons Christopher E. Cornwall (Creator); Steeve Comeau (Creator); Billy Moore (Creator); Quentin D'Alexis (Creator) Ocean acidification is a threat to the continued accretion of coral reefs, though some undergo daily fluctuations in pH exceeding declines predicted by 2100. We test...
