Because the time history of CFC concentrations in the atmosphere is relatively well known, they have provided an important constraint on ocean circulation. CFCs dissolve in seawater at the ocean surface and are subsequently transported into the ocean interior. Because CFCs are inert, their concentration in the ocean interior reflects simply the convolution of their atmospheric time evolution and ocean circulation and mixing.

WebCFCs can linger in the stratosphere for a century or more. There, intense UV radiation from the sun breaks bonds in CFC molecules, releasing their chlorine atoms. Scientists worried that intensified UV exposure at Earth's surface would promote skin cancer, damage crops, and kill off ocean phytoplankton, the base of the marine food chain.
