The Biogeochemistry Group at Eawag Kastanienbaum studies biogeochemical processes in lakes and marine systems. We have three main foci:

  • Investigating the process of anaerobic methane oxidation and anaerobic ammonium oxidation in sediments and water columns of lacustrine and marine systems.
  • Estimating methane emissions including diffusive emissions and ebullition from lakes and reservoirs.
  • Following degradation of organic material from the water surface through the water column and sediments using organic geochemical and isotopic tools.

Systems under investigation include African and Siberian lakes (Kivu, Baikal), lakes in Switzerland (Lake Rotsee, Lago di Cadagno, Lake Zug, Lake Lucerne, Lake Lugano), and Lake Van.
