Tidal frequency internal waves, generated by barotropic tidal flow over topographic obstacles in a stably stratified fluid, lead to local mixing near the generation site, both due to direct wave breaking (close to topography) and enhanced rates of interaction with other internal waves (well above topography).
At and just below a critical latitude where the Coriolis frequency is half the tidal frequency, particularly efficient wave-wave interactions of a parametric subharmonic instability type lead to a dissipation profile with high values extending several hundred meters above the bottom, before decaying rapidly to background levels, and q > 0.
The conclusion from our analysis is that we have unambiguously detected the residual oscillations in tidal frequency
This pattern of release minimizes the impact of visual predators on newly hatched zoeae and takes advantage of circulation at tidal frequency to transport zoeae away from intertidal habitats where conditions may not be favorable for larval development.
This pattern of release also takes advantage of circulation at tidal frequency to transport zoeae away from intertidal habitats where conditions may not be conducive to larval development.
This consists of upward migration during nocturnal flood tides, which allows megalopae to take advantage of circulation at tidal frequency
to facilitate further transport up the estuary (Tankersley & Forward 1994, Tankersley et al.
