             abstract = "Most of the knowledge on the surface circulation in the 
                         northwestern Atlantic off South America is based on geostrophic 
                         maps built on from sparse salinity/temperature profiles collected 
                         throughout the decades. Schematic pictures provided by previous 
                         researches have been important to elucidate the large scale 
                         circulation pattern, however uncertainties remains about the 
                         linkage in some regions. Almost none direct velocity data was 
                         collected in the eastern Atlantic between 10S and 20S. Recent 
                         direct velocity data collected by shipboard acoustic Doppler 
                         current profiler (S-ADCP) during the Brazilian PIRATA cruises, 
                         together with atmospheric data provided by radiosondes, reveal the 
                         existence of eastward flow generated by the wind field. Sverdrup 
                         transport computed from wind data also present eastward flow in 
                         the region. This recent feature can not be identified as the South 
                         Equatorial Countercurrent as it was described in the literature to 
                         lie on closer to the equator. How this eastward flow interacts 
                         with the sluggish South Equatorial Current system flowing westward 
                         is of major curiosity due to the bifurcation process. High 
                         resolution ocean numeric models also present this eastward flow 
                         and need to be used to better understand its variability. Coupled 
                         ocean-atmospheric models are needed to better understand possible 
                         feedbacks that might be related with climate over South America.",
