Biosphere-Geosphere interactions: Linking climate
I. Hajdas, L. Wacker; with S. Bernasconi, R. Smittenberg (ERDW, ETHZ)
The Damma Glacier, Canton Uri, Switzerland
Contact:
I. Hajdas
This interdisciplinary project aims at a detailed multidisciplinary study of the initial
phase of weathering to obtain a detailed picture of the processes
occurring at the biosphere-hydrosphere-geosphere interface and to
develop new geochemical tools to study weathering and soil formation
processes. The main part of the field
research will be carried out in the forefield of the Damma Glacier, in
Canton URI.

Radiocarbon dating is incorporated into Subproject 1: Organic carbon dynamics during weathering and soil formation
- Radiocarbon dating will provide information about the age of various organic fractions (fast and slow carbon pool)
- Development of compound-specific radiocarbon dating will allow dating minute amounts of biomarkers selected from the soil using High Performance Liquid Chromatography HPLC.
- On the basis of this project future applications to dating problems in various paleo archives (lake and ocean sediments, bone material) will be developed
