Les sédiments lacustres constituent l'une des meilleures archives continentales à notre disposition pour étudier les changements climatiques et environnementaux à haute résolution. Lors du projet PASADO (Potrok Aike Maar Lake Sediment Archive Drilling Project), nous avons prélevé une série de carottes sédimentaires de Laguna Potrok Aike, un maar situé au Sud de la Patagonie. De façon à reconstruire les derniers changements climatiques et hydrologiques à Laguna Potrok Aike, plusieurs de ces carottes ont été analysées en utilisant les diatomées comme principal proxy. Les résultats obtenus nous ont permis de mieux caractériser l'évolution du climat et de l'environnement local pour les derniers 50 cal. ka BP. Grâce à sa résolution temporelle un...
