Experimental determination of small-scale turbulence coefficients in the near-surface layer of the sea

Experimental and Field Research


The results of numerous experiments on the diffusion of fluorescent dyes are presented. To determine the turbulent diffusion coefficients, the technique involving under water photography of a jet with the subsequent processing of negatives by a microphotometer was used. The vertical coefficients were found to be slightly larger (by about 20%) than the horizontal ones, with the scale of the phenomenon being 0.3–1 m. Empiric relationships have been derived for the turbulent diffusion vertical coefficient on the parameters of surface waves.
