Concordia Research Station at Dome Circe, Charlie or Concordia.
The main part of the summer camp at Dome C (Concordia) Station in January 2005

Concordia Research Station, which opened in 2005, is a French-Italian research facility that was built 3,233 m (2.0 miles) above sea level at a location called Dome C on the Antarctic Plateau, Antarctica. It is located 1,100 km (680 mi) inland from the French research station at Dumont D'Urville, 1,100 km (680 mi) inland from Australia's Casey Station and 1,200 km (750 mi) inland from the Italian Zucchelli Station at Terra Nova Bay. Russia's Vostok Station is 560 km (350 mi) away. The Geographic South Pole is 1,670 km (1,040 mi) away. The facility is also located within Australia's claim on Antarctica, the Australian Antarctic Territory.

Concordia Station is the third permanent, all-year research station on the Antarctic Plateau besides Vostok Station (Russian) and the Amundsen–Scott South Pole Station (U.S.) at the Geographic South Pole. It is jointly operated by scientists from France and Italy and regularly hosts ESA scientists.

Location of the "Concordia Station" relatively near the South Pole

History

In 1992, France decided to build a new station on the Antarctic Plateau. The program was later joined by Italy in 1993.

In 1996, a French-Italian team established a summer camp at Dome C. The two main objectives of the camp were the provision of logistical support for the European Project for Ice Coring in Antarctica (EPICA) and the construction of a permanent research station.

The new all-year facility, Concordia Station, became operational in 2005. The first winterover began with a staff of 13 (eleven French and 2 Italians) in February 2005.

Access

Most of the cargo is moved to Dome C by traverse from Dumont d'Urville Station, covering 1,200 km in 7 to 12 days depending on weather conditions. Station personnel and light cargo arrive by air, using Twin Otter aircraft from DDU or Mario Zucchelli Station at 1200 km.

Environment

Dome C is one of the coldest places on Earth. Temperatures hardly rise above −25 °C in summer and can fall below −80 °C in winter with a recent record –84.6 °C in 2010. The annual average air temperature is −54.5 °C. Humidity is low and it is also very dry, with very little precipitation throughout the year.

Dome C does not experience the katabatic winds typical for the coastal regions of Antarctica because of its elevated location and its relative distance from the edges of the Antarctic Plateau. Typical wind speed in winter is 2.8 m/s.

Dome C is situated on top of the Antarctic Plateau, the world's largest desert. No animals or plants live at a distance of more than a few tens of kilometers from the Southern Ocean. However, south polar skuas have been spotted overflying the station, 1,200 km away from their nearest food sources. It is believed that these birds have learned to cross the continent instead of circumnavigating it.

Human biology and medicine

Concordia Station shares many stressor characteristics with long duration deep space missions, in particular extreme isolation and confinement, and as such serves as a useful analogue platform for research relevant to space medicine. During the winter the crew are without possibility of evacuation or deliveries for 9 months and live for a prolonged period in total darkness, at altitude almost equivalent to 4000m at the equator. The physiological and psychological strains on the crew are marked. Concordia station is particularly useful for the study of chronic hypobaric hypoxia, stress secondary to confinement and isolation, circadian rhythm and sleep disruption, individual and group psychology, telemedicine, and astrobiology. Concordia station has been proposed as the one of the highest fidelity real-life Earth-based analogues for long duration deep space missions.[1]

Glaciology

In the 1970s, Dome C was the site of ice core drilling by field teams of several nations. In the 1990s, Dome C was chosen for deep ice core drilling by the European Project for Ice Coring in Antarctica (EPICA). Drilling at Dome C began in 1996 and was completed on December 21, 2004, reaching a drilling depth of 3270.2 m, 5 m above bedrock. The age of the oldest recovered ice is estimated to be ca. 900,000 years.[2]

Astronomy

Concordia Station has been identified as a suitable location for extremely accurate astronomical observations. The transparency of the Antarctic atmosphere permits the observation of stars even when the sun is at an elevation angle of 38°. Other advantages include the very low infrared sky emission, the high percentage of cloud-free time and the low aerosol and dust content of the atmosphere.

Writing in the Proceedings of the Astronomical Society of the Pacific, Karim Agabi et al. discuss the suitability of the site for astronomy in terms of the seeing.[3] Their key finding:

The median seeing measured with a DIMM (Differential Image Motion Monitor) placed on top of an 8.5 m high tower is 1.3 ± 0.8 arcseconds.

This is significantly worse than most major observatory sites, but similar to other observatories in Antarctica. However, Lawrence et al. consider other features of the site and conclude that "Dome C is the best ground-based site to develop a new astronomical observatory".[4] Note however that this was written before whole-atmospheric seeing measurements had been made at Dome C.

The experiments to measure the astronomical conditions at the site were controlled by a computer system that had to supervise the generation of its own electricity using a jet-fuel powered stirling engine. The computer, running Linux, communicated with the outside world using an Iridium phone.[5]

Climate

The climate at Concordia Station is frigid all year round. It has a polar ice cap climate, with maximums ranging from −24.8 °C (−12.6 °F) in December to −62 °C (−80 °F) in May, mean ranging from −30.4 °C (−22.7 °F) in December to −65.3 °C (−85.5 °F) in May and minimums ranging from −36.1 °C (−33.0 °F) in December to −68.7 °C (−91.7 °F) in May. The station has never recorded a temperature above freezing; the warmest temperature recorded was −5.4 °C (22.3 °F) in January. The coldest recorded temperature was −84.6 °C (−120.3 °F) in August; one of the coldest temperatures ever recorded on Earth.

Winterovers

While the station is used in summer campaign since December 1997, the first winterover (February to October) was only made in 2005. During this period, the station is inaccessible, requiring total autonomy.

First winter-over (DC01 - 2005)

The first winter began in mid-February 2005, with thirteen wintering (eleven French people and two Italians):

In September 2005 the highest temperature was -48 °C, with an average in August of -60.2 °C and a record of -78.6 °C on 1 September. At these temperatures, trips outside had to be performed with the utmost care. Those going outside travelled at least in pairs and were equipped with a radio, spare batteries and a full fleece suit, with only the eyes at times visible. Glaciologist Italian Emanuele Salvietti had to take snow samples every day one kilometre from the base. As he had to walk (because no vehicle operates at these temperatures), he built a full face mask, with only a pipe to breathe. The slightest mistake would lead to certain injury, as astronomer Agabi Karim explained: "Burns on the cheeks and eyelashes glued to the lens of the telescope," after exposure to the freezing cold.

Second winter-over (DC02 - 2006)
