@article{fdi:30270, title = {{O}2 and {CO}2 balances approach for estimating biological production in the mixed layer of the tropical {A}tlantic {O}cean ({G}uinea {D}ome area)}, author = {{O}udot, {C}laude}, editor = {}, language = {{ENG}}, abstract = {{T}he 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 {O}2 and {CO}2 in the mixed layer over a 10-day period in the {G}uinea {D}ome area. {T}he rates of {O}2 production (10.3 mmol m-2 d-1) and {CO}2 consumption (13.0 mmol m-2 d-1) by photosynthetic activity exceed the evasion of {O}2 and {CO}2 into the atmosphere (respectively 2.4 and 1.2 mmol m-2 d-1). {T}he net apparent production of {O}2 from day to day is only 11% ofthe diurnal {O}2 increase. {T}he biological production of oxygen at a short distance from the center of the {G}uinea {D}ome appears to be higher than that in the exact center.
