We are investigating eddy mixing processes using idealized flow models for which the diffusion can be precisely controlled. The goals are to understand how material is transported by the fluctuating motions, in particular, (1) the ways in which fluxes are non-local (i.e., depend on more that just the value of the gradients of the mean at the point of interest), (2) the effects of inhomogeneities both in the means (where the non-local nature of stirring comes into play) and in the eddy properties, and (3) how fluxes for reacting
fields such as biogeochemical variables differ from passive tracers. Simulations together with analytical methods are used to gain a deeper insight into the processes acting and the interplay among them.
