<P> The ocean contains the greatest quantity of actively cycled carbon in this world and are second only to the lithosphere in the amount of carbon they store . Its surface layer holds large amounts of dissolved inorganic carbon that is exchanged rapidly with the atmosphere . The deep layer 's concentration of dissolved inorganic carbon ( DIC ) is about 15 % higher than that of the surface layer . DIC is stored in the deep layer for much longer periods of time . Thermohaline circulation exchanges carbon between these two layers . </P>
