Demographics of Antarctica
Antarctica has few permanent residents, and contains research stations and field camps that are staffed seasonally or year-round, and former whaling settlements. The largest station, McMurdo Station, has a summer population of about 1,000 people and a winter population of about 200. Approximately 29 nations, all signatory to the Antarctic Treaty, send personnel to perform seasonal (summer) or year-round research on the continent and in its surrounding oceans.
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.
