The Concordia research station in Antarctica is a place of extremes: for nine months no supplies can be delivered, the nearest living beings are 600 km away at the Russian Vostok station, and the Sun does not rise above the horizon for four months in the winter.
One thing is for sure: it is cold, dropping below –80°C, and the high altitude offers reduced oxygen in the air.
Concordia is run by the French and Italian polar organisations to collect data for subjects as diverse as glaciology, astronomy and climate science.
