Abstract:

The long-term goal of this 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 biogeochemical reactions occurring in coastal sediments. The objectives are to provide quantitative expressions of biogeochemical processes from field and laboratory studies and to develop a numerical model of early diagenesis which explicitly accounts for the complex interactions between the structural, mineralogical and biological components of coastal marine sediments. Each partner in this integrated study has specific objectives that will enable us as a group to achieve the long-term goal. NRLs objectives for the funded period of FY97 summer were to develop a methodology to quantify burrow networks in a coastal setting, sample burrows in a field site and characterize the burrows for future modeling efforts.
