The Use of Radionuclides (unsupported 210Pb, 7Be and 137Cs) in Describing the Mixing Characteristics of Estuarine Sediments

  • Chapter

Abstract

By studying sediment depth profiles of radioisotopes having different sources and half-lives we differentiate between steady-state accretion and mixing. The effect of 7Be and 137Cs source variability on the sediment-depth profiles of these isotopes is discussed. Mixing rates throughout any estuarine sediment deposit cannot be assumed to be constant. At sites identified as ‘mixed’ we investigate different mixing components and boundary conditions and in the upper estuary, we quantify bulk sediment movement.
