Introduction and overview

This course aims to provide an in-depth understanding of biogeochemical processes in complex environmental systems, specifically focusing on lake systems. It combines theoretical knowledge with practical skills, enabling students to conduct biogeochemical research through field investigations and laboratory analyses of lake water and sediment samples. Students will gain a conceptual understanding of biogeochemical processes and learn practical techniques to sample, measure, and interpret biogeochemically relevant compounds at different spatial scales in aquatic systems. The course aims to contextualize limnological theory practically, facilitating a field-based approach to understanding lake functioning and applying this knowledge to lake systems beyond those studied.

• Limnological Techniques in the Field

  • A range of freshwater sampling techniques, including water column and porewater sampling.
  • Measurement of physicochemical parameters, with an emphasis on oligotrophic vs. eutrophic systems.

      Biogeochemical Cycling in Lake Systems

  • Focus on redox processes and nutrient cycling in the water column and sediments.
  • The significance of these processes for water quality and ecosystem health.

      Coupling Between Physical and Biogeochemical Processes in Lakes

  • The importance of stratification on chemical processes.
  Exploration of natural chemical reactions and the dynamics of open vs. closed systems.

The course will be given in English due to integration into the Environmental Chemistry Master course. 10 people maximum - please enrol on CampusOnline/cmlife!

The class will run every Friday from 10:00-12:00 with a field/lab intensive (end of winter semester/beginning of following summer semester).
