Mise en place d'un échantillon de cellulose dans l'analyseur élémentaire couplé au spectromètre de masse. On mesure les rapports isotopiques 13C/12C et 18 O/16 O de la cellulose extraite des cernes de croissance annuelle des arbres. Ces recherches ont pour finalité la reconstitution des climats passés.
