             abstract = "A total of 1442 data series of 996 drifters from public and 
                         research databases were analyzed in order to decompose and to 
                         estimate the velocity field of surface currents between 30º S and 
                         50º S in the South Atlantic Ocean, with emphasis on the South 
                         Atlantic Current (SAC). The SAC is the southernmost limit of the 
                         South Atlantic Subtropical Gyre and presents strong interaction 
                         with other currents such as the Antarctic Circumpolar Current 
                         (ACC). The data were processed according to the Taylor's theory. 
                         The velocity field map for the study area as well as the mean 
                         values of the current intensity and associated standard deviation 
                         are presented and discussed. The highest estimated values of the 
                         average current velocity are located at the origin of the SAC and 
                         at the Malvinas Current (MC). The mean intensity of the SAC is 
                         approximately 30 cm.s-1 and the highest intensity values are 
                         observed at its origin decaying towards east. The SAC comprises a 
                         system containing a main axis and two branches, north and south. 
                         The N-SAC feeds the Benguela Current and the S-SAC leaks to the 
                         east towards the Indian Ocean. The flow pattern observed for the 
                         SAC presents a meandering characteristics and high variability in 
                         the regions where it interacts with other currents and mesoscale 
                         features.",
