Wave-driven flow over shallow reefs
Long-term (1 month) observations of waves and currents over a natural reef are presented which show a strong correlation between offshore rms incident wave height and cross-reef currents at subtidal frequencies. The energy spectrum of the cross-reef currents shows a significant peak at twice the semidiurnal tidal frequency, while the spectrum of sea surface elevation over the reef flat shows no...
متن کاملTime-dependent, wind-driven flow over a shallow midshelf submarine bank
[1] During summer 2001, high-resolution hydrographic, velocity, and bio-optical surveys were conducted over Heceta Bank off central Oregon. North of the bank, upwelling over simple bottom topography exhibited a classic response with a midshelf, baroclinic coastal jet and upwelled isopycnals. The coastal upwelling jet follows the bank topography as it widens offshore before reaching the southern...
متن کاملShallow-water wave lensing in coral reefs: a physical and biological case study.
Wave lensing produces the highest level of transient solar irradiances found in nature, ranging in intensity over several orders of magnitude in just a few tens of milliseconds. Shallow coral reefs can be exposed to wave lensing during light-wind, clear-sky conditions, which have been implicated as a secondary cause of mass coral bleaching through light stress. Management strategies to protect ...
متن کاملAn accurate model of wave refraction over shallow water
A computer model of wave refraction is desirable, in the context of landscape modeling, to generate the familiar wave patterns seen near coastlines. In this article, we present a new method for the calculation of shallow water wave refraction. The method is more accurate than previously existing methods and provides realistic wave refraction effects. We resort to Fermat’s principle of the short...
متن کاملSurface Acoustic Wave Driven Microchannel Flow
We demonstrate that the propagation of surface acoustic waves, arising from the excitation of the acoustic field on a piezoelectric crystal (lithium niobate) substrate, along the sidewalls of microchannels (50 μm or 280 μm wide and 200 μm deep) fabricated in the substrate, can give rise to throughflow with velocities of the order 10 mm/s. This streaming flow in the direction along which the sur...
