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.
List of agencies affected by the United States federal government shutdown of 2013
The United States Antarctic Program announced that it changed its three research stations to "caretaker" status, meaning that "[a]ll field and research activities not essential to human safety and preservation of property will be suspended". Most work at Antarctica is done between the months of October and February, when the region experiences summer. Because of the logistical difficulties involved in working in Antarctica, the shutdown may result in the cancellation of all American research in Antarctica for the entire 2013–2014 season. Scientists at McMurdo Station, Amundsen-Scott South Pole Station, and Palmer Station study topics such as biology, astrophysics and climate change.
