Sediment Mixing in Coastal Regions: The Impact of Animal Digestion on Radionuclide Tracers

Abstract

We focus on measurement of, and controls on, bioturbation in marine sediments. We seek to further our understanding of the solubilization of metallic elements during passage of marine sediments through the digestive systems of deposit feeders. Of particular interest are the implications of this solubilization for the dissolution of metallic contaminants in sediments and the metallic radionuclides used in measuring sediment bioturbation.
