The base Dumont d'Urville is first and foremost a scientific base, even if nowadays the transportation of supplies to the
Concordia Station (operated together with Italian researchers) represents an important part of the activity of the base. The French Southern and Atlantic Lands (TAAF) administration, the French Polar Institute Paul-Émile Victor (IPEV) and the French Navy jointly operate the icebreaker
''L'Astrolabe'' which is based out of Réunion. The vessel is used both to bring personnel and supplies to the Dumont d'Urville Station and for research and patrol duties.
Chemistry of the atmosphere The laboratory in atmospheric chemistry of the base is used to analyse, among other things, sulfur compounds present in the atmosphere.
Geophysics Nowadays, the study of geophysics is less present in the base. Nonetheless, several tools are still in use, notably a tide gauge, a cosmic rays detector, a GPS to measure the dip of the Antarctica into the
upper mantle, and a
lidar, which allows the analysis of the ozone depletion and the ozone holes.
Logistics The proper functioning of the base and supplying
Concordia requires significant logistics, especially in the summer. Technicians, including electricians, plumbers, mechanics for the electric plant and auto mechanics are essential for the proper functioning of the base all year round. In the 1950s the station had a small narrow-gauge railway for transporting supplies from a landing jetty to the main base. This was the only recorded railway ever in Antarctica. ==Climate==
