Dedicated to developing a fundamental understanding of environments and processes that regulate the volume and rates of production of abiogenic hydrocarbons and other organic species in the crust and mantle through geological time.
Utilize field-based investigations of approximately 25 globally representative terrestrial and marine environments to determine processes controlling the origin, form, quantities and movements of abiotic gases and organic species in Earth’s crust and uppermost mantle.
Implement the use of DCO-sponsored instrumentation, especially revolutionary isotopologue measurements, to discriminate the abiotic versus biotic origin of methane gas and organic species sampled from global terrestrial and marine field sites.
Quantify as a function of temperature, pressure, fluid and solid compositions, and redox state the mechanisms and rates of fluid-rock interactions that produce H2, abiotic forms of hydrocarbon gases and more complex organic compounds
Integrate our quantitative understanding of the processes that control the origins, forms, quantities and movements of abiotic vs biotic carbon compounds with the 4-D DCEM.
How are organic molecules such as methane formed in deep Earth?
Are these organic molecules formed independently from life (abiotically)?
What characteristics of deep Earth control the movements of organic molecules?
Did mineral-mediated chemical reactions play a role in life’s origins?
How do organic molecules influence the global carbon cycle?

Pr. Magali Ader is a professor at the Institut de Physique du Globe de Paris and serves on the Engagement Advisory Committee for DCO’s Deep Energy community. Her research sits at the intersection of Earth and life sciences, in the burgeoning field of geobiology. Using measurements of stable carbon and nitrogen isotope compositions of ancient sedimentary rocks, compared to those of analogous modern geobiological systems, she is contributing to our understanding of how Earth and life interacted through time on both a local and a global scale. Ader also serves as the international secretary of the Geochemical Society.
Dr. Chris Ballentine is chair of the Geochemistry Department at the University of Oxford. He has spent his scientific career developing and applying the noble gas isotope tool to different Earth systems. His research interests encompass understanding how the Earth gained its gaseous inventory and the processes controlling terrestrial reservoir interaction and evolution over time. Ballentine has been involved in organizing and building the governance and structure of the European Goldschmidt conferences since 2007; chairing Davos 2009, serving as the Goldschmidt officer for Prague 2011, and as co-convenor of Florence 2013. He also has served as president of the European Association of Geochemistry in 2013-2014.
Dr. Peter Clift shares his knowledge of the marine geology of Asia with students from around the world. He is the Charles T. McCord Professor of petroleum geology at Louisiana State University, the Hongguo Fellowship Professor at Nanjing Normal University, a research affiliate at Massachusetts Institute of Technology, and a visiting professor at the Chinese Academy of Sciences in China. His principal research interests focus on Asia and range from the geological aspects of the petroleum systems of South and Eastern Asia, to climatic and anthropogenic impacts on the environment in monsoonal Asia, to solid Earth-climate interactions. He also actively conducts research on active margins and the origin of the continental crust, with particular interest in mass balancing the carbon and solid rock flux through the global subduction system.
