Abstract
Abstract Plankton models must incorporate time-dependent flow fields to properly resolve the advective and eddy transports which shape the distribution of many biological and chemical variables in the sea. Models which exclusively use coefficients of eddy diffusivity to parameterize mixing processes are unable to achieve the same detail as those models in which variable flow can lead to an implicit turbulent flux. Using a model of the Oregon upwelling ecosystem, it is possible to calculate the complex eddy diffusivity which would have to be included in the model in lieu of realistic advection, although the authors do not recommend such a substitute. A demonstration of how an apparent negative eddy diffusivity can arise in advective plankton models and act to create gradients in biological fields is also included.
