[edit] Summary

Description
English: Estimated change in sea surface pH from the pre-industrial period (1700s) to the present day (1990s). Δ pH here is in standard pH units. This change is caused by the invasion of anthropogenic CO2 (see Ocean acidification). Calculated using Richard Zeebe's csys package with data from the Global Ocean Data Analysis Project[1][2] and World Ocean Atlas[3] climatologies. Δ pH is plotted here using a Mollweide projection (using MATLAB and the M_Map package).


Note that the GLODAP climatology is missing data in certain oceanic provinces including the Arctic Ocean, the Caribbean Sea, the Mediterranean Sea and the Malay Archipelago.
