Swedish Polar Research Secretariat
In 1987-1988, the Secretariat set up its first research station in Antarctica, Svea. The next year, the Wasa Research Station was opened. As of 2010, the Secretariat is also in charge of the Abisko Scientific Research Station in sub-arctic Sweden. In (northern) summer, it charters the icebreaker Oden from the Swedish Maritime Administration for research expeditions to the Arctic Ocean.
