Edouard Bard

[1] He is currently deputy director of the European Centre for Research and Education in Environmental Geosciences (CEREGE)[2] at the Arbois Technopole in Aix-en-Provence and coordinates the EQUIPEX ASTER-CEREGE,[3][4] project.

In 2009, he was a member of the Commission du Grand Emprunt national (Programme des investissements d'avenir) chaired by Alain Juppé and Michel Rocard, former prime ministers.

Its main objective is to understand the natural functioning of the ocean-atmosphere-cryosphere-biosphere system on time scales ranging from a few centuries to several million years.

New quantitative methods have allowed him to reconstruct past environments from various archives such as marine and lake sediments, corals, stalagmites and polar ice.

Edouard Bard's main scientific contributions concern the following topics: the diffusion of radiocarbon-labelled carbon dioxide in the ocean (first measurements in accelerator mass spectrometry,[14][15] variations in surface ocean temperature using organic, isotopic and elemental geochemistry indicators,[16][17][18][19][20][21][22] the dating of fossil corals by mass spectrometry of uranium and thorium to reconstruct sea level variations and to study the history of ice caps,[23][24][25][26][27][28][29][30][31] the innovative use of radiocarbon as a tracer of CO2 exchanges at the ocean-atmosphere interface,[32][33] the calibration of the radiocarbon dating method and the use of other cosmogenic nuclides such as beryllium 10 to reconstruct solar activity in the past, as well as variations in the geomagnetic field and the global carbon cycle.
