Discusses two mesocosm experiments designed to study the effect of nutrients and turbulence on trophic levels below fish larvae in the ecosystem. Creation of turbulence by oscillating grids; Generation of two levels of turbulence, high and low, utilizing two different frequencies, in a total of eight mesocosms in both experiments; Creation in each mesocosm of a two-layer density structure; Success in generating turbulence that mimics turbulence found in natural ecosystems, with turbulent eddies on larger scales than those relevant for organism interactions; Calculation of energy dissipation rates (k) from the frequency spectrums of the measured turbulent velocities; Results. |
