Summary
Annual mean sea surface CFC-12 concentration for the present day (1990s) from the Global Ocean Data Analysis Project climatology. CFC-12 here is in pmol kg−1 of seawater. It 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.
