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
