Group picture workshop Tuebingen III

Scientific program and report:

This 4-day workshop presented and discussed the application of several spectroscopic and microscopic techniques in environmental biogeochemistry. The course covered the background principles of these
techniques, as well as applications from the fields of biogeochemistry, environmental chemistry and geomicrobiology. The focus was on organic matter and microbe–mineral interactions (with special emphasis on iron oxides), soils and sediments, toxic metals (e.g. As, Cu) and organic contaminants.

-> Report on the Workhop


  • Scanning transmission X-ray microscopy (STXM)
  • Synchrotron-based X-ray absorption techniques (e.g., XANES, EXAFS)
  • Mössbauer spectroscopy – transmission electron microscopy (TEM)
  • Scanning electron microscopy (SEM) with focused ion beam (FIB) milling

Target group:

The workshop was aimed at PhD students and postdocs with a strong interest in biogeochemical processes. The presentations were given in English by leading international experts in the field.
This course was organized by

  • Andreas Kappler (University of Tübingen)
  • Thomas Borch (Colorado State University, USA)
  • Ruben Kretzschmar (ETH Zürich).

It was co-sponsored by the European Association of Geochemistry, the FIMIN Research Networking Program of the European Science Foundation and the U.S. National Science Foundation.
