Arctic Marine System Ecology (AMSE)
Erling Svensen

Our research group focuses on studies of structure and function of high-latitude marine ecosystems. We work on a large variety of organisms, ranging from bacteria through plankton, benthic animals and parasites, to top predators such as fish and marine mammals, and often take a system-level approach. Understanding trophic interactions, life cycles and the responses of organisms to various biotic and abiotic factors including changing climate are common interests within the group. Members of our group also ecotoxicological questions.

Members


Teaching

Our teaching activities are topics of Arctic marine ecology at the Bachelor and Master levels, and in marine ecotoxicology and pollution. 

 

Courses and teaching activities we lead are listed below. We also contribute to other courses.

Masters Projects 

Master students are an integral part of our research group and participate actively in group meetings, both scientific and social. If you are interested in a MSc project within our research group, feel free to contact our present our recently graduated MSc students for inside information about us and their projects. Many of the master students are also parts of ongoing national and international research projects - follow the links for more information.
