             abstract = "Polarimetric ALOS/PALSAR scenes were used to explore the behavior 
                         of metocean processes in the South Brazil Bight. The parameters 
                         evaluated from two different polarimetric approaches, the 
                         Cloude-Pottier decomposition and Kudryavstev et al. quad-pol 
                         analysis, were the basis for the study, supported by SST and 
                         scatterometer wind data. Although the traditional H-\α 
                         diagram labeled all the pixels as Bragg scattering dominant, when 
                         the results were analyzed in detail, subtle variations enabled a 
                         preliminary discrimination of data in three regions, where the 
                         signal is probably composed by different groups of scattering 
                         mechanisms: (1) [H: 0.11-0.14; \α: 4.5º-5.5º; A>0.45] region 
                         under influence of Subtropical Shelf Front (R{\'{\i}}o de la 
                         Plata plume), moderate wind from S-SW and probably a strong 
                         coastal current; (2) [H: 0.13-0.15; \α: 5.0º-6.5º; A>0.45] 
                         region under influence of Subtropical Shelf Front and low wind 
                         from SE; (3) [H: 0.16-0.17; \α: 5.5º-6.0º; A<0.3] region 
                         under influence of Brazil Current and low-to-moderate winds from 
                         SE. Kudryavtsevs parameters were complementary for that initial 
                         description of scattering mechanisms in each region. The 
                         polarimetric approach proved to be promising to discriminate 
                         metocean processes and the related scattering mechanisms. More 
                         scenes and areas should be analyzed in a near future to refine the 
                         study and start the development of a classification scheme for 
                         recurrent metocean processes at the Brazilian Margin.",
