Polar Research is the international, peer-reviewed journal of the Norwegian Polar Institute, Norway's central institution for research, environmental monitoring and mapping of the polar regions. Aiming to promote the exchange of scientific knowledge about the Arctic and Antarctic across disciplinary boundaries, Polar Research serves an international community of researchers and managers. Original primary research papers comprise the mainstay of Polar Research. Review articles, brief research notes and book reviews are also included. Occasional unreviewed solicited essays, usually on biographical or historical subjects, are selected to appeal to a wide audience of scientists and other readers. Special issues, typically conference proceedings, are published from time to time.
