Basics in hydrochemistry in aquatic ecosystems
Basics in nutrient chemistry, nutrient cycling
Human impacts on aquatic ecosystems (land use, flood protection, river regulation, climate change, etc);
Aquatic ecosystem functioning, linkage between terrestrail surroundings and streams/lakes
Biogeochemistry in WFD

Lab techniques that each student should know by the end of the week:
•Knowledge in basic laboratory skills (filtration, pipetting, standard rows, etc.)
•Introduction in different analytical methods and techniques for limnological investigations (photometric analyses, titration)
•Sample preparation and handling for water and sediment
•Determination of in-situ parameters such as temperature, conductivity and pH values
•Determination of oxygen concentration by Winkler titration method
* Determination of alkalinity and chlorophyll a
•Determination of inorganic phosphorus and SRP in water and sediments

Previous knowledge expected

no further requirements. registration for the master applied limnology

Objective (expected results of study and acquired competences)

After successful completion of this module, participants are able to:
•Describe major chemical properties of aquatic ecosystems;
•Identify and apply adequate methods to analyse chemical and physical properties of aquatic systems;
•Apply knowledge and skills to set up experiments and measurements of nutrient conditions of aquatic ecosystems and major processes involved (e.g. enzyme activity);
•Interpret and present research results in oral and written form (manuscript);
•Evaluate the role of environmental factors and anthropogenic impacts on nutrient conditions and chemical characteristics of lentic and lotic ecosystems.
