Tracer of Ocean Circulation
Since 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. Since CFCs are conservative, their concentration in the ocean interior reflects simply the convolution of their atmospheric time evolution and ocean circulation and mixing.

Famous quotes containing the words ocean and/or circulation:
“The improved American highway system ... isolated the American-in-transit. On his speedway ... he had no contact with the towns which he by-passed. If he stopped for food or gas, he was served no local fare or local fuel, but had one of Howard Johnson’s nationally branded ice cream flavors, and so many gallons of Exxon. This vast ocean of superhighways was nearly as free of culture as the sea traversed by the Mayflower Pilgrims.”
—Daniel J. Boorstin (b. 1914)
“There is probably not more than one hundred dollars in cash in circulation today. That is, if you were to call in all the bills and silver and gold in the country at noon tomorrow and pile them on the table, you would find that you had just about one hundred dollars, with perhaps several Canadian pennies and a few peppermint Life Savers.”
—Robert Benchley (1889–1945)
