||Primary source abstract: "The net amounts of CO(2) taken up by the oceans and released from the biosphere between 1970 and 1990 have been determined from the changes in three measured values: the concentration of atmospheric CO(2), the delta(13)C of atmospheric CO(2) and the delta(13)C value of dissolved inorganic carbon in the ocean."
||P.124 right column 3rd paragraph: "The fossil fuel-derived CO2 (primary source), which is released at a rate of about 4.25 x 10^14 mol CO2/yr, will not rapidly equilibrate with the ΣCO2 in the oceans."
