Alignment of insulated cases at the Cape Prudhomme base in Antarctica. They are intended to receive ice cores drilled during the ASUMA (Improving the Accuracy of the SUrface Mass balance of Antarctica) expedition. Three types of analysis will be conducted on these cores: chemical and isotopic, in particular to trace the penetration of oceanic air masses into the continent’s interior, and radioactive to assist in their dating. ASUMA is an ANR/IPEV programme under whose auspices a scientific expedition left point D10, a few kilometres from the French Dumont d’Urville base in Antarctica, on 1 December 2016, heading towards the centre of the continent. The goal of this programme is in particular to better understand the current evolution of the snow accumulated on the surface of Antarctica from one year to the next. This would make it possible to reduce uncertainty regarding its current regimen and its possible impact on sea levels. The ASUMA expedition took place in an area still largely unknown from a scientific point of view, because very few measurements have been made on the ground. It is a transition zone between the coast and the Antarctic Plateau.
