NSF Amundsen-Scott South Pole Station

Location

  • Positioned at 90°S, the geographic South Pole.
  • Sits atop the Antarctic ice sheet at an elevation of approximately 2,835 meters (9,301 feet) above sea level.
  • Located in the interior of Antarctica, one of the most remote and extreme environments on Earth.
  • Due to ice movement, the station drifts approximately 10 meters (33 feet) each year.

Biodiversity, natural environment and climate

  • The station is surrounded by a polar desert, characterized by ice and snow. It is one of the harshest climates on Earth.
  • Due to the extreme cold and isolation, there is very limited biodiversity. No native plant or animal life exists at the South Pole itself.
  • Annual average temperature is around -49°C (-56°F), temperatures can drop below -80°C (-112°F) during winter.
  • Precipitation is minimal, averaging about 2.5 cm (1 inch) per year, primarily as ice crystals.

History

  • Opened in 1956 as part of Operation Deep Freeze to support scientific exploration during the International Geophysical Year (1957-1958).
  • Named after Roald Amundsen, the first to reach the South Pole in December 1911, and Robert F. Scott, who arrived shortly after in January 1912.
  • The original station, the “Old Pole,” was built by an 18-man U.S. Navy crew, the first group to winterover at the South Pole.
  • In 1975, the central area of the station was rebuilt as a geodesic dome 50 meters wide and 16 meters high that covered modular buildings, fuel bladders, and equipment. Several science and berthing structures were added in the 1990s.

Facilities

  • The current elevated station was completed in 2008 to improve resistance to snow accumulation and harsh conditions.
  • Infrastructure includes approximately 47 buildings of varying sizes, including housing, offices, science laboratories, a store, a food growth chamber and dining, recreation and medical services.
  • South Pole hosts the Martin A. Pomerantz Observatory, Atmospheric Research Observatory, South Pole Telescope, seismic instruments and a massive in-ice neutrino detector, the IceCube South Pole Neutrino Observatory.
  • Resupply operations during the austral summer (November to mid-February) bring up to 450,000 gallons of fuel, personnel and cargo.
  • Most personnel travel from NSF McMurdo Station on ski-equipped aircraft, while cargo and fuel often arrive via surface traverse from McMurdo Station.

Population

  • Up to 150 people during a week in the summer season.
  • Up to 42 people during a week in the winter season.
  • 640 people move through the station annually.
  • 24,354 meals are served a year.

Scientific research and activities

  • The station supports scientific studies in astronomy, astrophysics, aeronomy, auroral studies, geospace research, meteorology, geomagnetism, seismology, earth-tide measurements and glaciology.
  • The station's geographic location allows unique astronomical observations, benefiting from clear, dry air and the absence of light pollution.
