137cs dating sediment

ABSTRACT: Purpose of this research was to study the rate at which the semi-enclosed bay such as the Kaštela Bay reacts to the coastal processes of industrialization and urbanization, the extent of the influence of human activities on the bay, and the sediment distribution affected by anthropogenic influence.

210Pb CRS model was also used for understanding of recent sedimentation change.

The sediment accumulation rates for the CRS model ranged from 0.022 to 0.038 g·cm−2·yr−1 with an irregular high value of 0.12 g·cm−2·yr−1 around 1932 at Zigetang Lake core in the past eighty years.

Zigetang Lake located in the central Tibetan Plateau was selected for the purpose of understanding of recent sedimentation rates.

Based on 137Cs dating marker, the sediment rate was 0.077 cm·yr−1.

The sedimentation rate was calculated to be 0.071 cm·yr−1 and 0.029 g·cm−2·yr−1 on the basis of 210Pb CIC model.

Pb profiles in certain lakes (most in New England) and pollen dates suggest that bioturbation, physical mixing, changes in sedimentation rate, or acidification may be occurring, but this is insufficient to account for the deviant Cs at prefallout sediment depths is due mostly to net downward molecular diffusion and adsorption, and that surface concentration is due to net upward diffusion and adsorption (and possibly also biological uptake), recycling of sedimentary Cs in this sediment may be a function of release by organic decomposition and scarcity of clay minerals for adsorption.
