             abstract = "Stable isotopes have been widely used in the literature both to 
                         discuss current ocean circulation processes, as well as to 
                         reconstitute paleoceanographic parameters. The distribution of 
                         oxygen and deuterium stable isotopes in seawater (\δ18Osw 
                         and \δDsw) at the Western Tropical South Atlantic border was 
                         investigated to better understand the main fractionation processes 
                         of these isotopes and establish a regional salinity and 
                         \δ18Osw relation to improve the paleoceanographic knowledge 
                         in the region. This study was conducted during a quasi-synoptic 
                         oceanographic cruise in which 98 discrete seawater samples were 
                         collected in the core of the main water masses for stable isotope 
                         analysis. A strong correlation between \δ18Osw and \δD 
                         was found, which made it possible to extrapolate the results for 
                         \δ18Osw to \δD. Although it was not possible to 
                         distinguish the water masses based only on their isotopic 
                         signatures, the water masses had a strong salinity and 
                         \δ18Osw relation, and compared with previous studies, a 
                         seasonal pattern was observed. Paleosalinity differences of up to 
                         0.2 psu between Summer and Winter are reported. Considering the 
                         limitations of the current techniques to seasonally separate the 
                         samples for the paleoceanographic studies, an intermediate Mixing 
                         Line for the Tropical South Atlantic (SSS = 1.942* \δ18Osw + 
                         34.56) was proposed to reduce the estimated errors associated with 
                         these seasonal variations.",
