The Laboratory for Dendroclimatology aims to reconstruct the temporal and spatial variability of the climate of the past utilizing multi-parameter tree ring analysis and to assess and verify the causes of climate change and its impact on woody plants.

The following tasks are covered:

• quantitative analysis of the climate-signal transfer from atmosphere through soil and leaf into the wood of tree rings (Monitoring, calibration and verification of tree ring parameters vs. instrumental …

In the Organic Surface Geochemistry Lab (OSGLab) of the Geomorphology section, the smallest of molecules and isotopes open a door to the past. In the OSGLab we conduct research on regional differences of the causes and effects of past climate change and variations in biochemical cycles. In some projects, we can determine the "traces" of climate change down to a decade, in other projects biogeochemical processes are traced over millions of years.
In the laboratory, changes in the carbon …
