Inhaltliche Voraussetzungen (erwartete Kenntnisse)

Limnochemistry and nutrient cycling or equivalent course
Basic knowledge in laboratory work


After successful completion of this module, participants are able to:
•Discuss alterations of and linkage between carbon and inorganic nutrient cycles in aquatic ecosystems;
•Apply a wide range of methods to analyse major chemical and physical properties of different compartments of aquatic ecosystems;
•Analyse various nutrient fluxes and their interaction in aquatic ecosystems including water and sediment compartments;
•Develop an experimental setting to investigate biogeochemical cycles in field sites and experimental settings
•Evaluate results of own measurements reflecting major ecosystem properties.
