%X The rates at which concentrations of oxygen and carbon dioxide change under the influence of exchange with the atmosphere and biological production are derived from #in situ$ measurements of O2 and CO2 in the mixed layer over a 10-day period in the Guinea Dome area. The rates of O2 production (10.3 mmol m-2 d-1) and CO2 consumption (13.0 mmol m-2 d-1) by photosynthetic activity exceed the evasion of O2 and CO2 into the atmosphere (respectively 2.4 and 1.2 mmol m-2 d-1). The net apparent production of O2 from day to day is only 11% ofthe diurnal O2 increase. The biological production of oxygen at a short distance from the center of the Guinea Dome appears to be higher than that in the exact center. (Résumé d'auteur)
