The long-term goal of the study is to develop a better mechanistic and quantitative understanding of the effects of biologically-enhanced transport, mineralogy, sediment fabric, and particle surface chemistry on the biogeochemical dynamics of coastal marine sediments. Objectives of the study are to 1 develop robust mathematical representations for sediment mixing, irrigation and sediment fabric, 2 parameterize transport and fabric functions using tracer experiments, high-resolution deterministic and stochastic submodels, measured profiles of physical and chemical properties of sediments plus pore waters, and high-resolution imaging of sediment fabric and statistical analysis of burrow networks, 3 incorporate the transport and fabric functions in an existing computer code for multicomponent reactive transport in aquatic sediments, and 4 perform sensitivity analyses and simulations.
