                         Ocean off the Amazon River mouth is amongst the most energetic 
                         regions in the world for generation of internal tides (Baines, 
                         1982). Since the early 1980s there have been in situ observations 
                         of Internal Solitary Waves (ISWs) near the North Equatorial 
                         Counter Current (NECC) off the Brazilian continental shelf, where 
                         localized surface velocity pulses of up to 2 m/s have been 
                         documented (e.g. Brandt et al., 2002). Despite these early 
                         efforts, the region remained largely unexplored until recently. 
                         Here we present a first account of the coherence crest-lengths, 
                         propagation characteristics and seasonal variability of ISWs on 
                         and off the shelf, based on Synthetic Aperture Radar (SAR) images. 
                         Available ENVISAT ASAR scenes (29 in total), and additional 
                         ERS-1/2 SAR, TerraSAR-X and RADARSAT images of the region of the 
                         tropical Atlantic Ocean comprising the geographic coordinates 
                         [40- 50 W, 0- 8 N] have been examined. The SAR image analysis 
                         revealed the following main results: 1) The ISW signatures, whose 
                         coherence crest-lengths can exceed 200 km, are first detected near 
                         the southern edge of the countercurrent and intensify on the 
                         northern edge of the NECC; 2) In October, there is a strong 
                         refraction/ advection of ISWs towards the east, as they enter the 
                         influence of the NECC (in between 4 and 5 N); 3) Some on-shelf 
                         regions are prone to intense ISW signatures in the SAR, which are 
                         believed to be associated with intricate bottom-topography.",
