Simulation of the carbon cycle in the oceans. Annual report, Third year, September 15, 1992--September 14, 1993

In this report, the authors conclude that the average oceanic uptake of anthropogenic CO{sub 2}, as determined from four different ocean models and normalized to the observed mean penetration depth of bomb{sup {minus}1} {sup 4}C (analogue to anthropogenic CO{sub 2}), is 2.0 {plus_minus} 0.5 GtC/yr (decade 1980--1989). This oceanic uptake plus the year-to-year growth of the atmospheric CO{sub 2} content together are less by 1.8 {plus_minus} 1.2 GtC/yr than the estimated anthropogenic CO{sub 2} emissions from fossil fuels and land use.
