ON RELATIVE ROLES OF TURBULENT AND ADVECT IVE FACTORS IN THE DISPERSION OF DYE PATCHES IN THE SEA

The relative roles of turbulent and advective factors in the dispersio n processes in the sea are estimated. The numerous data of diffusion d ye experiments are used for these purposes. The variability of maximum dye concentration and the depth of the dye penetration are chosen as representative criteria of the process. It was found that the contribu tion of advective factors in the dye dispersion can considerably excee d the pure diffusion (turbulent) effects in frontal zones, Langmuir ci rculations, convective regions, near sharp bottom topography variation s and in the regions with large velocity shear.
