These animations show the monthly difference in surface seawater pH between two reference periods: 2030-2035 and 2050-2054 averages. The outputs are based on simulations from a regional biogeochemical ocean model for the Atlantic Canada region, forced with atmospheric outputs from three global climate models (CanESM2, MPI, and HadGEM2) under the RCP 8.5 emissions scenario. Each frame represents a single month of the year. Seawater pH is a measure of acidity, with lower values indicating more acidic conditions. Decreases in pH are associated with ocean acidification and can negatively affect marine organisms, particularly shell-forming species.
