Severe tissue damage in Atlantic cod larvae under increasing ocean acidification
Ocean acidification, caused by increasing atmospheric concentrations of CO2 (refs 1, 2, 3), is one of the most critical anthropogenicthreats to marine life. Changes in seawater carbonate chemistry have the potential to disturb calcification, acid–base regulation, blood circulation and respiration, a...

Ocean acidification, caused by increasing atmospheric concentrations of CO2 (refs 1, 2, 3), is one of the most critical anthropogenicthreats to marine life.
