“…1a), when very low salinity values (<35) are observed at the near shore surface at depths of less than 20 m, associated with continental outflows. A high salinity core (>36.8) is verified near 100 m depth in Figure 10a, and this may be associated with the core of the NBUC in this area, as indicated by field measurements and studies of numerical modelling Schott et al, 1998;Bourlès et al, 1999;Stramma et al, 2005). These results suggest that physical mechanisms contributing to the BL formation in the Amazonian shelf break area may be analogous to those observed in the western Pacific ocean, as proposed by Vialard & Delecluse (1998a,b) and Cronin and McPhaden (2002).…”

“…The circulation pattern in the equatorial Atlantic ocean is quite complex: strong quasi-zonal westward currents and eastward countercurrents coexist within the thermocline and subthermocline layers (Schott et al, 1995(Schott et al, , 1998Boebel et al, 1999;Bourlès et al, 1999Bourlès et al, , 2002. In addition, seasonal variations in horizontal advection play an important role in the net surface heat flux and ocean heat budget (Hastenrath, 1977;Merle, 1980).…”

“…Ao longo de 44°W o sistema da CNB/SCNB transporta água em torno de 35 Sv a 36 Sv (1 Sv = 10 6 m 3 s-1 ) em direção ao Equador, com uma amplitude de variação sazonal média de 3 Sv (Johns et al, 1998;Schott et al, 1998;Bourlès et al, 1999a). Em geral, a máxima velocidade da CNB é localizada na isopicna de 24,5, com fluxo em torno de 60-100 cm.s -1 .…”
