Research at the station

The station’s unique location between a freshwater lake and the sea offers superb conditions for both freshwater and brackish water studies.
The Ar Research Station is used both for research activities within the University and by external researchers, and also for student projects and degree projects. A number of research projects have been carried out, and several published scholarly articles, PhD theses and degree projects have been produced at Ar.
