The trichlorofluoromethanes (CFMs) that have been so much in the news may be very good tracers for oceanic water masses. Gradual accumulations since 1946 have brought the concentration of this gas in the atmosphere to a level of approximately 100 parts per trillion. A small portion of this material dissolves in surface waters, marking them as having been in contact with the atmosphere. Thus old water masses that have long been out of contact with the atmosphere should be free of CFMs.
