Dissipative Losses in Nonlinear Internal Waves Propagating across the Continental Shelf

Creator:

Moum, J. N., Farmer, D. M., Shroyer, E. L., Smyth, W. D., and Armi, L.

Abstract:

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⁻¹, and amplitude, a = 15 m. The wavelength L gradually decreased from 220 m in 170-m water depth to 60 m in...

Structure and Generation of Turbulence at Interfaces Strained by Internal Solitary Waves Propagating Shoreward over the Continental Shelf

Creator:

Moum, J. N., Farmer, D. M., Smyth, W. D., Armi, L., and Vagle, S.

Abstract:

Detailed observations of the structure within internal solitary waves propagating shoreward over Oregon's continental shelf reveal the evolving nature of interfaces as they become unstable and break, creating turbulent flow. A persistent feature is high acoustic backscatter beginning in the vicinity of the wave trough and continuing through its trailing...
