  abstract = {{S}ix cruises have been carried out in the eastern equatorial {A}tlantic between {J}une 2005 and {S}eptember 2007 to study the distribution of the surface total alkalinity ({TA}) and dissolved inorganic carbon ({DIC}). {D}uring these cruises a strong north-south gradient is observed in sea surface temperature ({SST}), sea surface salinity ({SSS}), {DIC} and {TA}. {L}ow surface salinity waters are associated with low {TA} and low {DIC}. {T}hey are observed north of the equator (0 degrees-6 degrees {N}) in the {G}uinea current, whereas higher concentrations are observed south of the equator. {TA}-{SSS} and {DIC}-{SST}-{SSS} relationships are determined and are used to calculate surface f{CO}(2). {M}onthly maps of f{CO}2 are obtained, on a one degree grid, using {SST} and {SSS} fields for the region 10 degrees {W}-10 degrees {E}, 6 degrees {N}-10 degrees {S} from {J}une to {N}ovember. {T}he monthly mean flux of {CO}2 ranges from 1.69 +/- 1.94 mmol m(2) day(-1) in {N}ovember to 2.78 +/- 1.65 mmol m(-2) day(-1) in {A}ugust over the region. {U}sing the same gas exchange coefficient, the {CO}2 flux was calculated with the climatological {A}f{CO}(2). {O}ur estimates show a stronger gradient between northern and southern waters than the climatology, probably due to a lack of data in the climatology as well as its 4 latitude by 5 longitude resolution.},
