More than 100 scientists from around the world gathered to share their latest research findings regarding the role of deep carbon in planetary function at the Pacifico Yokohama Conference Center on 26 June 2016. The Deep Carbon Observatory (DCO) Symposium in Yokohama brought together leaders of the four DCO Science Communities and their eminent Japanese colleagues for an exciting, interactive, daylong session of discussion and discovery. Co-chairs from DCO’s Deep Life, Deep Energy, Reservoirs and Fluxes, and Extreme Physics and Chemistry Communities presented recent findings, while their Japanese colleagues shared their research endeavors and how they are contributing to deep carbon understanding on a global basis. DCO colleagues Eiji Ohtani (Tohoku University, Japan), a member of the DCO Executive Committee, Fumio Inagaki (JAMSTEC, Japan), Kagi Hiroyuki (University of Tokyo, Japan), and Yuji Sano (University of Tokyo, Japan) organized the collaborative symposium in conjunction with the DCO Executive Committee and Secretariat.
“The symposium exemplified DCO’s strengths – the global nature of its collaborative research, the collegial exchange of information among experts from many different disciplines, extraordinary scientific accomplishments, and shared passion for uncovering the scientific secrets of deep carbon," said DCO Director Craig Schiffries (Carnegie Institution for Science, Geophysical Laboratory, USA). “By all accounts, it was both an enjoyable and productive day and we are very grateful to our Japanese colleagues for making it happen.”
Symposium organizer and DCO Executive Committee member, Eiji Ohtani, added, “this event was an important opportunity to expand current collaborations and build new ones among Japanese scientists and our international colleagues within the burgeoning field of deep carbon science.”
The Symposium capped three days of DCO Executive Committee meetings and events in Yokohama. The events began with a tour of the International Ocean Discovery Program’s drilling vessel, D/V Chikyu, the world’s largest scientific research ship with its advanced onboard laboratory for real-time analysis during scientific expeditions. DCO Executive Committee members traveled to Shimizu port in Shizouka and boarded the 210-meter long, 57-ton ship that can accommodate up to 200 crew and scientists. Shin’ichi Kuramoto (Director General, Center for Deep Earth Exploration (CDEX)/Japan Agency for Marine-Earth Science and Technology (JAMSTEC)), Kyoshi Suyehiro (Principal Scientist, JAMSTEC), and Yusuke Kubo (Science Operation Group, Science Service Department, CDEX and Project Manager for IODP Expedition 370) hosted the group and shared details of the vessel’s impressive capabilities during a private tour.
Kubo also presented an overview of the exciting upcoming expedition aboard D/V Chikyu: “T-Limits of the Deep Biosphere off Muroto.” The expedition’s lead proponent Kai-Uwe Hinrichs (MARUM, University of Bremen, Germany) and co-chief scientists, Verena Heuer (MARUM, University of Bremen, Germany), Fumio Inagaki (JAMSTEC, Japan), and Yuki Morono (JAMSTEC, Japan), are all members of DCO’s Deep Life Community who hope to better define the temperature limits to life in the deep subseafloor.
Many members of DCO’s international scientific community stayed on after the formal DCO meetings to give keynote lectures and presentations at Goldschmidt 2016. Terry Plank (Lamont Doherty Earth Observatory, USA) delivered a plenary lecture, “The Volatile Input to Volcanoes and Eruption,” to a packed auditorium. Robert Hazen, Craig Manning, and Kai-Uwe Hinrichs were among several DCO scientists delivering keynote talks throughout the week of the conference. Alexandra Navrotsky (University of California Davis, USA) received the VM Goldschmidt Award for her outstanding contributions to geochemistry, and Laurence Yeung (Rice University, USA) received the FW Clarke Award, which recognizes outstanding contributions from early career scientists.
