abstract = "A satellite synthetic aperture radar (SAR) data set facilitates
investigation of the two-dimensional structure of internal
solitary waves (ISWs) that propagate near the Amazon River mouth.
Three distinct groups of waves are identified according to their
propagation direction. While cross-shelf ISW propagation has been
previously documented, it is found that the majority of the waves
propagate along the shelf and upstream of the North Brazilian
Current (NBC). These ISWs appear in packets with interpacket
separations of ~4 km, mean crest lengths of 10 km, and
intersoliton separations of ~500 m. They are observed throughout
the entire semidiurnal and fortnightly tidal cycles, but their
origin appears to result primarily from the steady NBC, modulated
by tidal currents, as it flows over shallow bottom topography. A
Froude number analysis considering mode-1 nonhydrostatic linear
waves propagating upstream of the NBC is found to be consistent
with a regime of transcritical generation in the study region.",
