Kinematics of CO2 fluxes in the tropical Atlantic ocean during the 1983 northern summer

CO2 evasion within the Atlantic equatorial belt (5°N-5°S) increases from the East to the West (Andrié et al., 1986). Many factors contribute the variations of pCO2 in the equatorial surface waters. To assess their relative importance, a kinematic box model is developed. A 2° x 2° box whose depth is defined by the 24.90 °/°° isopcynal level flows westward from 4°W to 38°W within the Equator-2°S band with the south equatorial current. Time (zonal) evolution of nitrate, total CO2, total alkalinity and mass, and of the corresponding water pCO2, are simulated taking into account advection, meridional divergence, diffusion, biological activity and gas exchange. Initial and boundary conditions are taken from the FOCAL 4 (July-August 1983) data se
