As atmospheric concentrations of CFC-11 drop, the global ocean should become a source of the chemical by the middle of next century.
The world’s oceans are a vast repository for gases including ozone-depleting chlorofluorocarbons, or CFCs. They absorb these gases from the atmosphere and draw them down to the deep, where they can remain sequestered for centuries and more.
Marine CFCs have long been used as tracers to study ocean currents, but their impact on atmospheric…
