Abstract

This project will evaluate soil organic matter dynamics in the Kuchibuto River, Japan, affected by the Fukushima accident using 137Cs and carbon stable isotopes (δ13C). 137Cs binds to fine sediment and organic matter, and may be stored in the landscape for long periods. Vegetation decay, detrital organic matter reworking, and soil carbon degradation and mineralisation affect carbon storage, release and transfer in catchments. We will assess detrital organic matter for reliable δ13C and 137Cs signatures, and develop a conceptual model to help predict future changes in 137Cs and soil carbon flux.
