                         depth (MLD) in the Abrolhos and Vit{\'o}ria-Trindade region based 
                         on sea winds derived from the QuikSCAT scaterometer and numerical 
                         model outputs generated by the Parallel Ocean Program (POP) model 
                         from 1999 to 2003 in the region between 13ºS-23ºS and 44ºW-28ºW. A 
                         combination of horizontal maps of wind speed, wind-stress curl and 
                         Hovmoller diagrams are used to address this issue. Wind speeds of 
                         5 to 6.6 m/s were found during summer season, while during 
                         wintertime, the speed of the wind reached values from 6.6 to 8.4 
                         m/s. The summertime MLD derived from POP varied from 10 to 20 
                         meters, whereas the wintertime MLD reached depths down to 100-125 
                         meters. Based on the analysis of the wind stress curl, it was 
                         expected that positive values would induce upwelling, whereas 
                         negative values would be an indicative of downwelling. The results 
                         showed positive values all season-round during the period of 
                         study. A good agreement between positive wind stress curl and 
                         upwelling were observed during spring. However, north of ~15ºS 
                         during the autumn-winter of 2000, autumn of 2001 and 2003, the 
                         curl of the wind stress was negative. Our results suggested that 
                         the depth of the mixed layer could be driven by other forcings 
                         instead of being purely related to the dynamics of Ekman in the 
                         area of study.",
