What drives the process of turbulent diffusion in aquatic environments?

Turbulent diffusion in aquatic environments is primarily driven by atmospheric motions such as wind. When wind blows across the surface of a water body, it generates surface waves and currents. This agitation causes mixing within the water column, enhancing the transportation and dispersion of particles, heat, and dissolved substances throughout the aquatic environment. The turbulence created by these atmospheric effects facilitates the movement of materials, leading to a more homogeneous distribution of solutes and organisms in the water.

The process is distinct from other factors like thermal stratification, which refers to the layering of water due to temperature differences and does not enhance mixing. Similarly, while biological activity can contribute to nutrient cycling and localized mixing through the movement of organisms, it does not drive diffusion in the same way that wind does. Chemical reactions may transform substances within the water but do not contribute to the dispersive mixing associated with turbulent diffusion.
