Optional Fieldtrip

"TERENO catchment Schäfertal and the research station Bad Lauchstädt"

In a small catchment (1.44 km2) within the Harz mountains water and matter fluxes are explored at multiple scales using Lysimeters, soil-moisture networks and cosmic ray probes. This is combined with the exploration of subsurface structures using geophysical tools, remote sensing and soil-landscape modeling.

On the way back the UFZ Research Station in Bad Lauchstädt is visited where among others the TERENO SoilCan projects and the "Global Change Experimental Facility" — a large infrastructure for climate manipulation experiments — is presented.

9–11Trip to the Schäfertal catchment
11–13Schäfertal site: demonstration and presentation
13–14Trip to Bad Lauchstädt (GCEF)
14–15GCEF site: demonstration and presentation
15–16Trip to Leipzig
