AEW-20706 Practical course Aquatic ecology and water quality.

Contents:

This field course will be organised once every one or two years, depending on registration and availability. The topic of the field course will alternate between Limnology and Marine Ecology, and the field practical will either go to a fresh water system or a tropical marine coastal system. Note: this field course has a maximum number of participants. Students that have performed the courses mentioned above under “assumed knowledge” will get priority. In this course the focus is on the critical processes which play an important role in aquatic ecosystems including eutrophication. In particular we will study processes and stressors that connect land and aquatic systems. The field survey includes;- in-situ measurements of indicative abiotic and biotic variables which reflect the water quality status of the aquatic system; - water, sediment and plant sampling for nutrient analysis; - conduction of short-term experiments that determine critical interactions among aquatic organisms and influence the water quality. A series of experiments will be done in order to assess primary production and decomposition of organic matter in sediments, foodweb interactions. And methods of mitigating stressors (e.g. P-release, hydrology) will be tested and evaluated.

Learning outcomes:

After successful completion of this course students are expected to be able to:
- understand complexity of processes in an aquatic ecosystem under stress (e.g. eutrophication);
- acquire and analyse field data;
- design and perform advanced field experiments;
- setup a basic system analysis of a coastal marine ecosystem or waterbody including the catchment that incorporates land-sea interactions.

Activities:

- follow lectures and discuss content in the group;
- design and perform experiments on a shallow lake or a tropical marine coastal system;
- fieldsurvey at the field site;
- analyse data and report on system analysis.

Examination:

Students will be assessed on their contribution to the fieldwork (50%) and the group report (50%).
