Letter from the Director

The Deep Carbon Observatory is commemorating a decade of research by producing four books, eight special collections of scientific papers, a decadal report, workshops, conferences, videos, virtual reality, music, and art. This month, I would like to begin by highlighting two forthcoming books and two special issues of journals. 

Craig Manning, Wendy Mao, and Jung-Fu Lin are editors of Carbon in Earth’s Interior, a forthcoming AGU Monograph containing 27 chapters synthesizing research by DCO’s Extreme Physics and Chemistry community. This volume, scheduled for publication in early 2020, contains important contributions in mineral physics, materials science, petrology, and geochemistry. 

From Crust to Core: A History of Deep Carbon Science by Simon Mitton recounts the stories of 140 scientists from 200 B.C. to the start of DCO. Cambridge University Press will publish this book, which provides the first history of deep carbon science, in mid-2020.   

A special collection of papers in American Mineralogist on “Earth in Five Reactions: A Deep Carbon Perspective" addresses the five most important chemical reactions that drive the planetay carbon cycle from core to atmosphere and make Earth a habitable planet. Edited by Jie Li, Simon Redfern, and Donato Giovannelli, this special collection stems from a DCO workshop in March 2018. 

A special collection on “Deep Carbon Science” in the open access journal Frontiers will contain over 20 papers by more than 100 authors from all four DCO science communities. Isabelle Daniel, Sabin Zahirovic, Dan Bower, Artur Ionescu, Mattia Pistone, Sami Mikhail, and Dawn Cardace edited this special collection, which includes contributions by numerous early career scientists. 

In a paper published in Nature, DCO researchers Bernard Marty, Michael Broadley, and Claude Jaupart present geochemical evidence for high volatile fluxes at the end of the Archean eon, which has profound implications for the deep carbon cycle and the Great Oxidation Event. 

DCO’s Carbon Mineral Challenge concluded with a celebratory session at the Geological Society of America Annual Meeting in Phoenix, Arizona, USA. The session, which was chaired by Daniel Hummer and Grethe Hystad, featured presentations on some of the 31 new carbon minerals discovered in the past four years.

We look forward to seeing a large continent of DCO colleagues at the American Geophysical Union Fall Meeting in San Francisco, USA on 9-13 December 2019. The conference will feature more than 100 presentations that will help launch the next decade of deep carbon science.

Mantle ‘Tantrum’ Released Burst of Volatiles at End of Archaean Eon
Natural processes that move carbon through Earth, like plate tectonics, subduction, and volcanic activity, seem old and stable today, but the planet wasn’t always so calm. During the Archaean eon (4 to 2.5 billion years ago) - Earth’s teenage years - the planet was hotter and had more volcanic eruptions. This eon ended with a rise in atmospheric oxygen called the Great Oxidation Event, which was the very beginning of the more mature plate tectonics that we recognize today. In a new paper in Nature, a team of researchers, including DCO Reservoirs and Fluxes Community members Bernard Marty and Michael Broadley (CRPG-CNRS, France) and Executive Committee member Claude Jaupart (Institut de Physique du Globe de Paris, France), detected a sharp rise in volcanic activity between 2.6 to 2.2. billion years ago that likely released a burst of water, carbon dioxide, and other volatile compounds into the atmosphere. The researchers analyzed traces of Archaean atmosphere trapped within fluid-filled bubbles called inclusions inside rocks that formed at that time. They propose that this massive flux of volatiles may have started the Great Oxidation Event. Read more...

Frontiers Special Collection Engages Broader Deep Carbon Community
In a new special collection on Deep Carbon Science in the online journal Frontiers, deep carbon researchers within and beyond the DCO community had the opportunity to contribute findings from their work on the slow, deep carbon cycle. DCO members from all four research communities edited the collection, including Isabelle Daniel (Université Claude Bernard Lyon 1, France), Sabin Zahirovic (University of Sydney, Australia), Dan Bower (University of Bern, Switzerland), Artur Ionescu (Babeș-Bolyai University, Romania), Mattia Pistone (Université de Lausanne, Switzerland), Sami Mikhail (University of St. Andrews, UK), and Dawn Cardace (University of Rhode Island, USA).

A Deep History of Deep Carbon Science
For hundreds of years, geographers, physicists, chemists, and geologists labored in disparate fields to understand Earth, its origins, and how it functions as a planet. A new book connects these researchers, from the Ancient Greeks up until the beginning of the Deep Carbon Observatory, to tell the complex and interconnected story of the evolution of deep carbon science. From Crust to Core – a History of Deep Carbon Science, by astronomer and science historian Simon Mitton (University of Cambridge, UK), recounts the stories of 140 scientists whose work has informed our understanding of the deep carbon cycle. Now in press with Cambridge University Press, the publication will be available in mid-2020. Read more...

“Earth in Five Reactions” Synthesizes Evolution of A Habitable Planet
In March 2018, scientists from across DCO’s four research communities met at the Carnegie Institution for Science, USA, for a two-day workshop. Their goal was to decide the five most important chemical reactions that drive the global carbon cycle from atmosphere to core and make Earth a habitable planet. After much discussion, the group voted for the winners: hydrogenation/dehydrogenation, carboxylation/decarboxylation, carbonation/decarbonation, aqueous silicate melt/solid, and hydration/dehydration. These reactions are now the focus of a special collection in American Mineralogist called "Earth in Five Reactions: A Deep Carbon Perspective." Extreme Physics and Chemistry (EPC) Community member Jie Li (University of Michigan, USA), EPC and Reservoirs and Fluxes Community member Simon Redfern (University of Cambridge, UK), and Deep Life Community member Donato Giovannelli (University of Naples "Federico II," Italy) edited the collection.

The Carbon Mineral Challenge Finds 31 New Carbon Minerals
The Carbon Mineral Challenge was set in motion by DCO at the 2015 AGU Fall Meeting, with the goal of finding at least some of Earth’s 145 “missing” carbon minerals. The Challenge built on the work of DCO Executive Director Robert Hazen (Carnegie Institution for Science, USA) and colleagues, who used data science and statistical methods to look at the known minerals on Earth and predict those that should exist but remained undocumented. From the outset, DCO early career scientist and study co-author Daniel Hummer (Southern Illinois University, USA) pioneered the Challenge, working with an international advisory board to seek out sources of new minerals. Read more...

Virtual Reality Lets DCO Researchers See C in 3D
At the recent Deep Carbon 2019 meeting in October in Washington D.C., scientists grabbed and manipulated molecules, waded through giant networks of minerals, and walked through the air above an active volcano, simply by donning virtual reality (VR) goggles and holding a black handset. The 3D, interactive demonstrations were created by Oliver Kreylos and Magali Billen (both at University of California, Davis, USA) as part of DCO’s Modeling and Visualization Forum. Three groups of DCO scientists are collaborating with Kreylos and Billen to visualize their data in new ways through VR technology. Read more...

Putting Deep Life on the Map
Decades of drilling into Earth’s crust has revealed a vast and poorly explored habitat for microbes. Some scientists are trying to fill in the gaps by combining existing sampling data with what we know about subsurface habitats. Robert Pockalny (University of Rhode Island, USA), Sabin Zahirovic, Xiaodong Qin (both at University of Sydney, Australia), and Rick Colwell (Oregon State University, USA), along with members of the EarthByte group and the DCO Engagement Team, compiled and mapped existing sampling sites onto a virtual model of Earth to create a 3D, interactive globe of deep life. The 3D globe can be accessed on any web browser, and clicking on a site brings up additional information including the depth, age, and environment where the samples were collected, as well as the scientific publication that contains the data set.
