Lecture by Prof. Bernard Marty, 2022 EAG Distinguished Lecturer
Recorded at Konkoly Observatory, Research Centre for Astronomy and Earth Sciences, Budapest, Hungary
Volatile elements such as hydrogen, carbon, nitrogen and oxygen are essential ingredients to build habitable worlds like Earth, but their origin and evolution on terrestrial planets remain highly debated. Here we discuss the processes that distributed these elements throughout the early Solar System and how they then became incorporated into planetary building blocks. The sources of planetary volatiles and the timing at which they were accreted to growing planets probably play a crucial role in controlling planet habitability.

Bernard Marty is a Professor of geochemistry at the Ecole Nationale Supérieure de Géologie, University of Lorraine, and researcher at the Centre de Recherches Pétrographiques et Géochimiques (CRPG, UMR 7358 CNRS-UL), Nancy, France.
He is interested in the geochemistry and cosmochemistry of volatile elements, notably stable isotopes and noble gases. Topics include stable isotope variations in the solar system, processes of planet formation, the origin(s) of terrestrial water and other volatiles, the geodynamical cycle of these elements, and the evolution of the atmosphere from the Hadean eon to Present. Besides mantle geochemistry, Bernard is involved in space missions such as Stardust (return to Earth of cometary grains), Genesis (analysis of the isotope composition of the solar wind), Rosetta (in situ analysis of cometary volatiles), and others.
Bernard was co-chair of the Meteoritical Society meeting in Nancy in 2009, and chair of the Goldschmidt Conference in Prague in 2011, serving as EAG Goldschmidt Officer from 2009 to 2014. He was also EAG President in 2017-2018.
