[6] Chappellaz earned his Diploma of Advanced Studies (DEA) and wrote his doctoral thesis at Joseph Fourier University in Grenoble, within the Laboratory of Glaciology and Environmental Geophysics, which was directed by the glaciologist Claude Lorius.
[6] Jérôme Chappellaz began his career at the CNRS with a year at the Goddard Institute for Space Studies (NASA) in New York, headed by Professor James Hansen.
There he carried out the very first work of modeling the global biogeochemical cycle of atmospheric methane in the glacial and interglacial period, revealing the major role played by variations in the extent of wetland, in particular in tropical regions, in the natural evolution of this greenhouse gas.
[2] The IPEV oversees French science in the Arctic, Antarctic, and Sub-Antarctic Islands; the director's role is to ensure logistical support in all these regions.
[12] Chappellaz told reporters that, due to rising temperatures, Alpine glacier cores must be preserved before melting surface water contaminates lower ice layers.
