Bases de données et modélisation
- Simulations paléoclimatiques: dernier millénaire (relation avec ESCARSEL (France); Millenium (6e PCRD)), Holocène (PMIP III) -> besoins en calcul. Modèles regionaux.-Base de données paléo de type Medias-France (?): stockage (données et méta-données paléo-céanologiques, paléo-écologiques, paléoclimatiques, archéologiques, historiques …) -> faciliter le croisement des divers types de données et simulations-S’appuyer sur l’existant: WDC, PMIP, Pangea …
