Quantitative Chemical Mass Transfer in Coastal Sediments During Early Diagenesis: Effects of Biological Transport, Mineralogy, and Fabric

Abstract

The long-term goal 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. The objective for FY98 was to develop methods to quantify the transport processes in cohesive coastal sediments based on fabric data. The short-term goals for the accomplishment of this objective included (1) the synthesis of data obtained during the FY97 field study in the Dry Tortugas, Florida, in terms of biologically-induced pore water mixing, (2) completion of field studies in fine-grained coastal environments, and (1) quantitative description of pore water and sediment mixing and biologicallyinduced fabric heterogeneity for the new field site.
