Summary
In the Laboratory of Physical Geography in Meudon, Agnès Gauthier, a palynologist, reconstitutes the paleoenvironment and the paleoclimates which were active in our part of the world during a hundred of thousands years. She indentifies and counts pollen grains extracted from sediment cores, which were sampled from the Maar of Allerêt, a volcanic lake now dried up, located in the Massif Central.
