  abstract = {{T}his paper is based on a comparison of the carbon parameters at the western and eastern borders of the tropical {A}tlantic using data collected from 55 cruises. {O}ceanic and coastal data, mainly total alkalinity ({TA}), total dissolved inorganic carbon ({CT}), sea surface salinity ({SSS}) and sea surface temperature ({SST}), were compiled from different sources. {T}hese data were subdivided into three subsets: oceanic data, coastal data and adjacent to the {B}razilian (western) and {A}frican coastal areas (eastern) data. {S}ignificant differences between the {TA} data (2099.4 ± 286.4 {M}u mol kg-1) at the western and eastern edges (2198 ± 141.9 {M}u mol kg-1) were observed. {D}ifferences in the {CT} values between the western edge (1779.6 ± 236.4 {M}u mol kg-1) and eastern edge (1892.2 ± 94.2 {M}u mol kg-1) were also noted. {T}his pattern was due to the different variabilities in the carbon parameters between the eastern and western border coastal areas and to the biogeochemistry that drives these parameters. {I}n the western coastal area, the physical features of the continental carbon and oceanic waters mixing with the freshwater that flows from the {A}mazon and {O}rinoco {R}ivers to the {S}outh {A}merican coast are different than the physical features of the water that flows from the {C}ongo, {V}olta and {N}iger {R}ivers in the eastern region. {A}pplying the {TA} empirical relationship to {TA} with values of {SSS}?<?35 in the western and eastern regions leads to a higher root mean square error (rmse) in the eastern and western regions. {T}herefore, most of the existing {TA} empirical relationships are most useful at the regional scale due to the difference in the water properties of each region. {T}he relationships of {TA} and {CT} determined in the western and eastern regions do not reproduce in situ data well, especially at the adjacent edges. {T}his difference is explained by the difference between the {A}frican and {B}razilian coasts in terms of their carbon parameter characteristics and processes responsible for their variation. {B}ased on the mixing model, it has been shown that the primary productivity in the eastern region is higher than that in the western region. {T}his is one of the reasons why the carbon parameters are higher in the eastern region. {F}or each region studied, an equation for {TA} is introduced in this study.},
