High altitude lakes in the French Alps : Contribution to the high altitude lakes and mountain environments knowledge since the end of lateglacia
The aim of the thesis is the study of the reconstitution of the high altitude lakes story in a changing environment since 10 000 years and the study of the present state of the lakes. The first part explains the story of lakes in high mountains. In the first chapter, the localisation of the lakes is...
