slide1

In the field,

coring at sea and on land to retrieved ice cores, lacustrines cores

In the labs,

Screen technics like XRF, RX, magnetic parameters, AMS, mass spectrometers, geochemical analyses

Data managment and computer time and facilities,

continental drilling and micropaleontological analyses

Continental drilling and micropaleontological analyses

One main tools for paleoenvironment investigations is lacustrine cores and determination of micro-organisms present in the samples

SETEL

Speleothèmes

MC-ICP-MS

slide8

RX and XRF facilities

National instrument at EPOC, Bordeaux

slide9

Mass spectrometer to determine the C and O isotopic composition of biocarbonates, speleothems, tree rings, …

slide11

Geochemical analyses

Molecular indicators, major and trace elements, O and C isotopes on bicarbonates, speleothems, tree rings, tephrochronology…

bases de donn es et mod lisation

Bases de données et modélisation

Croiser les informations et les 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 …
