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.
