Target group

Bachelor’s or Master’s students with basic knowledge in ecology, environmental or aquatic sciences


This course introduces students to the overall picture of environmental impact on the Baltic Sea. It will do so by analysing the role of catchment area and inland waters in the water quality and eutrophication of coastal waters. During the intensive field course the students will learn how land management, control of water pollution and ambient ecosystem dynamics affect water quality and ecosystems, and how this changes on the way from headwaters along the river basin to the Baltic Sea. The course will give a deeper understanding of the nutrient processes and their spatial and temporal dynamics in catchments and coastal areas, including transportation, modification and retention of nutrients and organic material.

Learning objectives

After completing the course, the students have knowledge of different Finnish aquatic ecosystems from headwaters to coastal waters of the Baltic Sea. Students will have gained insights into how the land use in catchment areas affects the water quality and biology. They will also have learned basic sampling and analytical methods used in aquatic ecology.

Course format and teaching methods

The course will be held at two field stations, Lammi Biological Station and Tvärminne Zoological Station and ends with an excursion to Askö Laboratory in Stockholm, Sweden.

The course contains lectures, excursions, fieldwork, group work and some laboratory work with water analyses. Excursions are made to different inland and coastal water bodies.

Course readings

Articles will be handed out during the course.

Means and criteria of assessment

Assessment is based on class participation and activity, group exercises and on completed personal essay. Students are divided into 4–5 groups. Items for group exercises and for personal essay are given during the Viikki Campus period. Syntheses of group exercises are presented at the stations. Assessment: participation during lectures and fieldwork 40%, group exercise 40% and essay 20%. Grading scale: 5 = excellent 4 = very good 3 = good 2 = average 1 = poor 0 = fail.
