CFCs and SF6 as tracers of ocean processes

Research output: Chapter in Book/Report/Conference proceedingChapter

3 Scopus citations


The anthropogenic compounds chlorofluorocarbons (CFC-11 and CFC-12) and sulfur hexafluoride (SF6) have been introduced into the atmosphere and been dissolving in the ocean in trace amounts. Their changing atmospheric sources make them useful as ocean tracers giving the added dimension of time. Global tracer data sets from repeated occupations such as Go-Ship are making it possible to document variability from natural and anthropogenic climate change in ocean ventilation and biochemical processes-including oxygen utilization and anthropogenic CO2 inventories.
