NOTES AND CORRESPONDENCE Dissipative Losses in Nonlinear Internal Waves Propagating across the Continental Shelf
A single nonlinear internal wave tracked more than 100 wavelengths across Oregon’s continental shelf over a 12-h period exhibited nearly constant wave speed, c 0.75 m s , and amplitude, a 15 m. The wavelength L gradually decreased from 220 m in 170-m water depth to 60 m in 70-m water depth. As the water shallowed beyond 50 m, the wave became unrecognizable as such. The total energy decreased fr...
متن کاملNonlinear internal waves over New Jersey’s continental shelf
[1] Ship and mooring data collected off the coast of New Jersey are used to describe the nonlinear internal wave (NLIW) field and the background oceanographic conditions that formed the waveguide on the shelf. The subinertial, inertial, and tidal circulation are described in detail, and the background fluid state is characterized using the coefficients of the extendedKorteweg–deVries equation. ...
متن کاملShore - parallel Sediment Transport by Waves and Tides in Inner Shelf Waters
In shallow waters the combined action of waves and currents significantly affects the motion of sediment on the bottom, and hence the nature and phase of their interactions with each other contribute to the shaping of the beach. Using pressure and velocity data collected just outside the surfzone (in two meters depth) on the south shore of Martha's Vineyard, MA, we compared the variations in ne...
متن کاملObservations of nonlinear internal waves on the outer New England continental shelf during the summer Shelfbreak Primer study
Observations are presented of nonlinear internal waves on the outer New England continental shelf during the summer Shelfbreak Primer study conducted between July 26 and August 5, 1996. Current and temperature measurements were made with an upward looking acoustic Doppler current profiler (ADCP) located on the 147 m isobath near the shelfbreak and three vertical thermistor moorings located upsh...
متن کاملObservations of Polarity Reversal in Shoaling Nonlinear Internal Waves
Observations off the New Jersey coast document the shoaling of three groups of nonlinear internal waves of depression over 35 km across the shelf. Each wave group experienced changing background conditions along its shoreward transit. Despite different wave environments, a clear pattern emerges. Nearly symmetric waves propagating into shallow water develop an asymmetric shape; in the wave refer...
