Nonlinear 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 کاملEnergy transformations and dissipation of nonlinear internal waves over New Jersey’s continental shelf
The energetics of large amplitude, high-frequency nonlinear internal waves (NLIWs) observed over the New Jersey continental shelf are summarized from ship and mooring data acquired in August 2006. NLIW energy was typically on the order of 105 Jm−1, and the wave dissipative loss was near 50 W m−1. However, wave energies (dissipations) were ∼10 (∼2) times greater than these values during a partic...
متن کاملMode 2 waves on the continental shelf: Ephemeral components of the nonlinear internal wavefield
[1] Shoreward propagating, mode 2 nonlinear waves appear sporadically in mooring records obtained off the coast of New Jersey in the summer of 2006. Individual mode 2 packets were tracked between two moorings separated by 1 km; however, packets could not be tracked between moorings separated by greater distances from one another (∼10 km). The inability to track individual packets large distance...
متن کاملHorizontal ducting of sound by curved nonlinear internal gravity waves in the continental shelf areas.
The acoustic ducting effect by curved nonlinear gravity waves in shallow water is studied through idealized models in this paper. The internal wave ducts are three-dimensional, bounded vertically by the sea surface and bottom, and horizontally by aligned wavefronts. Both normal mode and parabolic equation methods are taken to analyze the ducted sound field. Two types of horizontal acoustic mode...
متن کاملNOTES 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...
