Lehrinhalt

Lectures:
• Theory in organic carbon and nutrient cycling and GHG emission of aquatic ecosystems
• Theory in ecosystem metabolism and human impacts on aquatic ecosystems (e.g. land use change)
• Presentation of different advanced limnochemical methods and discussion of their relevance in hydrochemical and water quality studies
Student seminars on selected papers in that field (each student presents one paper)

Laboratory techniques:
Determination of organic carbon and dissolved organic matter properties in water and sediments (OM extraction, EEMs, absorption spectra)
Analyses of enzymatic activities and bacterial abundances in water and sediments
Determination/Demonstration of benthic respiration (CO2, CH4 production) and denitrification
Experiments on the effects of soil leachates on aquatic microbes
Data analysis and preparation of report

Inhaltliche Voraussetzungen (erwartete Kenntnisse)

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

Lehrziel

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 chemical properties of organic carbon cycling in aquatic ecosystems;
•Analyse various carbon and 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.
