Summary

Mixing, whether biological or physical, is a key process during the early diagenesis of aquatic sediments. A full appreciation of the effects of mixing requires quantification through the application of models. This chapter reviews the types of models available to describe mixing, emphasizing their relations to each other. Some of these models are then applied to common diagenetic situations, i.e., radiotracer, organic matter, and opal diagenesis, in order to illustrate the effects of mixing and to compare the predictions from different assumed modes of mixing. Finally, this chapter presents simple models for mixing of microbial populations in surface sediments.
