Course contents:
The course includes lectures, field and laboratory exercises. Processes in different types of lakes, principles for sampling and analysis of water and sediment samples are reviewed. Field methodology: representative sampling of water, sediment and biological samples. Field measurements (in situ). Laboratory work: analyses of collected sample material. Report writing: reporting of results that are placed in a limnological context. Critical assessment of data collected in the field.
Learning outcome:

After completing the course, the candidates must:

- Have an overview of possible sampling sites and important field methods in lakes

- Be able to carry out important physical, chemical and biological analyses of fresh water

- Be able to assess the link between important processes in lakes on the basis of limnological data and catchment properties

- Be able to perform representative sampling and have a knowledge on measurement uncertainty in limnological field investigations.

- Understand that fresh water is a vulnerable resource, and that knowledge-based management is a basis for preservation of water quality with regard to biological diversity and physical / chemical properties.

Learning activities:
Lectures on basic field and laboratory methodology in freshwater. Fieldwork, where students gain experience with various sampling methods, in situ measurements used in limnological surveys, water flow measurements, as well as knowledge of uncertainty related to water sampling. Field work in different types of lakes with different land use in the catchment. Laboratory analyses of collected sample material (water and sediment samples). Final reporting where field observations and laboratory measurments are presented and related to limnological processes.
Teaching support:
The course is supported by skilled persons within limnology and hydrology, and laboratory technicians during the whole period.
Handed out in lectures.
VANN200, VANN210, VANN220.
Recommended prerequisites:
Mandatory activity:

Both participation in field and laboratory activities and writing of reports must be passed for the students to pass the course. The students are assessed during the course through field and laboratory work. Furthermore, the students are assessed in a group report where they summarise their results.

Samlet vurdering: The evaluation of the course is based on the report (50 %) and the work in the field and laboratory (50 %). Grading system: Pass / Fail.
