Field courses are an integral part of studies in biological and environmental sciences. Specialised courses are arranged at TZS as well as at the biological stations at Lammi and Kilpisjärvi. The courses at TZS focus on marine topics. Each year around 20 courses in bio-, geo- and environmental sciences at the University of Helsinki are organised at the station. In addition, courses are organised by other institutions, such as the open university, universities of applied sciences, high schools, and other universities. Also non-biology courses and seminars can be organised at TZS.
