EPC community co-chairs Craig Manning (University of California Los Angeles, USA) and Wendy Mao (Stanford University, USA) organized the meeting, which was hosted by Everett Shock (Arizona State University, USA). Early career researchers and leaders in deep carbon research from around the globe presented talks and posters on new insights into carbon and its interactions with other elements in environments ranging from shallow reservoirs in soils and crustal rocks to Earth’s deep mantle and core. Among the topics discussed were problems that could be addressed through analysis of natural samples, experiments, and computational simulations. These included the origin of organic compounds essential to life (e.g. Nir Goldman, Lawrence Livermore National Laboratory, USA), the incorporation and distribution of carbon in Earth (e.g. Damanveer Grewal, Rice University, USA), and thermodynamic and kinetic limits to the stability of carbon-bearing phases (e.g. Jackie Li, University of Michigan, USA). Members of the EPC community presented 23 posters showcasing results on the solubility, partitioning, melting, redox behavior, and thermodynamics of carbon and/or carbon-bearing materials at extreme conditions.
The program also included several presentations on new initiatives for EPC-related research beyond the DCO program’s conclusion in 2019. Bjoern Winkler (Goethe University Frankfurt, Germany) introduced CarboPaT, a German collaboration for research on carbonates in the deep Earth, and Alexandra Navrotsky (University of California Davis, USA) spoke of the work of ThermoCon, a consortium for thermodynamics research. Deep Carbon Observatory Director, Craig Schiffries (Carnegie Institution for Science, USA), discussed opportunities for forming new collaborations and extending deep carbon science. EPC project leaders also discussed plans for an upcoming monograph featuring advances in deep carbon science from each research group in the community that will lay a foundation for ongoing work.
The workshop also included a discussion of data management and sharing in the community. Members from each group participated in a data hackathon. The hackathon coincided with a week-long workshop sponsored by the ENKI (Enabling Knowledge Integration) project and offered hands-on opportunities to discuss and enter data. ENKI lead Mark Ghiorso (OFM Research, USA) and co-PI Aaron Wolf (University of Michigan, USA) opened the joint effort by explaining how ENKI databases and open software can be used to make thermodynamic modeling of geochemical systems routine and accurate. Jenna Adams (University of California Santa Barbara, USA) and Lucy Tweed (Columbia University, USA) offered multiple examples of new applications of these tools. As part of the DCO’s commitment to its funder, the Alfred P. Sloan Foundation, EPC community data will be openly archived on the DCO Data Portal. Kathy Fontaine (Rensselaer Polytechnic Institute, USA) presented examples of data and metadata and instructions for uploading and preserving EPC research on the DCO Data Portal.
