  abstract = {{T}he carbon system in the eastern tropical {A}tlantic remains poorly known. {T}he variability and drivers of the carbon system are assessed using surface dissolved inorganic carbon ({DIC}), alkalinity ({TA}) and fugacity of {CO}2 (f{CO}2) measured in the 12° {N}-12° {S}, 12° {W}-12° {E} region from 2005 to 2019. {A} relationship linking {DIC} to temperature, salinity and year has been determined, with salinity being the strongest predictor. {T}he seasonal variations of {DIC}, ranging from 80 to 120 {M}u mol kg-1, are more important than the year-to-year variability that is less than 50 {M}u mol kg-1 over the 2010-2019 period. {DIC} and {TA} concentrations are lower in the northern part of the basin where surface waters are fresher and warmer. {C}arbon supply dominates over biological carbon uptake during the productive upwelling period from {J}uly to {S}eptember. {T}he lowest {DIC} and {TA} are located in the {C}ongo plume. {T}he influence of the {C}ongo is still observed at the mooring at 6° {S}, 8° {E} as shown by large salinity and chlorophyll variations. {N}evertheless, this site is a source of {CO}2 emissions into the atmosphere.},
