             abstract = "We present an analysis of internal solitary waves (ISWs) on the SE 
                         Brazilian continental shelf using a set of Envisat/ASAR satellite 
                         images. For the 17-month observation period, 467 ISW packets were 
                         detected. Most of observed solitons were associated to 4 
                         6ms\−1 wind.The number of ISW packets shows a seasonal 
                         signal with a peak in summer, with higher concentration in the 
                         outer shelf in all seasons, followed by midshelf during the 
                         summer. Propagation direction of ISWs was predominantly onshore 
                         with packets separated by typical \𝑀 2 internal tide 
                         wavelengths (\∼1040 km). The highest values of the 
                         barotropic tidal forcing F are concentrated at the shelf break 
                         between 200 and 500misobaths.These characteristics suggest that 
                         ISWs are formed fromnonlinear disintegration of internal tides 
                         generated at the shelf break that propagate shoreward as 
                         interfacial internal waves. No significant change in the number of 
                         ISWs from spring to neap tides was observed in spite of 
                         significant tidal current variation (60%). Even not being a region 
                         of strong tides, this study shows that ISWs are a frequent and 
                         widespread feature, possibly playing a significant dynamic role, 
                         affecting biological production, sediment dispersion, and 
                         transport.",
