Generation and dissipation of coastal internal tides

Turbulence and Internal Tides on the Continental Slope

“…This suggests that continental slopes may be sinks for internal tides generated in the deep ocean. This contrasts with the earlier paradigm of internal tide generation at the shelf break (Prinsenberg et al 1974;Baines 1982) radiating semidiurnal internal waves into the deep ocean and onto the shelf. In laboratory experiments of internal waves reflecting off sloping topography, McPhee-Shaw and found that the exchange of fluid between the turbulent boundary layer and the quiescent interior was controlled by the turbulent mixing at the boundary which could in turn be diagnosed by the convergence of across-slope internal wave energyflux.…”

Tidal band current variability over the Northern California continental shelf

“…Because high modes will take longer to travel from the generation to the observation site, they will be more severely damped upon arrival. (4) LeBlond (1966) and Prinsenberg, Wilmot and Rattray (1974) showed that the low modes are also favored by the preferenti ali nterna 1 di ssi pati on of the hi gher modes, due to their increased vertical shear. As a result of a combination of these mechanisms, the lowest modes will be dominant even in areas only a short distance away from the generation site.…”

Analysis and interpretation of tidal currents in the coastal boundary layer

“…al., 1975 show that internal tides are common--probably because nearby regions, particularly the continental slope, are areas where internal tides are generated (Prisenberg, Wilmot, andRattray, 1974, andCox andSandstrom, 1962). Current measurements near the coast, however, are rare, despite theoretical interest in this so called "corner region" (Wunsch, 1969).…”
