Carottage dans les réseaux souterrains d'Orgnac, en Ardèche. Le carottier est fixé au sol et le prélèvement des sédiments de calcite est réalisé verticalement jusqu'à une profondeur maximale de 2 m. L'étude des carottes permet d'étudier les variations de conditions environnementales durant la croissance du plancher stalagmitique.
