Description :
The AA. focus on a dry-based lake, i.e. frozen to the bottom, of the Dry Valleys of South Victoria Land to study how sediment becomes trapped in the lake ice. The study is based on data obtained not only from sedimentological investigations but also from ice composition analyses. Stable isotopes (δD and δO 18), major ions and gas composition analyses were performed, together with textural and structural analyses. The results put forward how a layer of aeolian sediments was trapped in the ice.
