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

Abstract

LONG-TERM GOALS. 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. OBJECTIVES. Objectives for FY97 were (1) to establish field methods to quantify biologically-enhanced mixing, and (2) to initiate the quantification of the mixing. APPROACH. Approaches during FY97 included (1) designing and deployment of deliberate particle tracer experiments to quantify the rate of biologically-enhanced mixing at a coastal field site, and (2) establishment of dissolved O2 as a tracer for the study of pore water irrigation in high spatial resolution.
