Letter from the Director

The Deep Carbon Observatory had a momentous month in October 2019, with the debut of a book, special issues of journals, a decadal report, videos, a short documentary film, and a symphony as well as an international conference and three workshops. 

Cambridge University Press published an open access DCO book, Deep Carbon: Past to Present, containing 20 chapters by more than 100 authors from around the world. Edited by DCO members Beth Orcutt, Isabelle Daniel, and Rajdeep Dasgupta, this 669-page volume is a tour de force that synthesizes our current understanding of carbon in Earth. 

A Nature collection on Deep Carbon showcases a broad array of DCO research papers and review articles, many of which are freely available for one year. The collection contains more than 40 papers published in Nature, Nature Communications, Nature Reviews Microbiology, Nature Geoscience, and Nature Microbiology.

DCO developed a special issue of Elements on “Catastrophic Perturbations to Earth’s Deep Carbon Cycle,” which explores major, rapid shifts in the carbon cycle, including their impact on Earth and contributions to mass extinctions. Celina Suarez, Marie Edmonds, and Adrian Jones edited this open access collection. 

DCO released a decadal report, Deep Carbon Observatory: A Decade of Discovery, which highlights ten transformational discoveries in a decade of deep carbon science. The report also synthesizes DCO from multiple perspectives, discusses DCO’s history and strategy, and addresses the future of deep carbon science. A DCO video and animation accompanied publication of the open access report. 

DCO premiered a short documentary film, Above and Beyond: Measuring volcanic emissions with drone technology. Filmmaker Zach Voss accompanied DCO’s ABOVE expedition to Papua New Guinea, where he documented how advances in drone technology are being harnessed to measure volcanic gases from within previously inaccessible volcanic plumes. 

Integrating science and art, the Royal Scottish National Orchestra recorded Symphony in C: A Carbon Symphony by composer David Earl. The musical work reflects Robert Hazen’s book, Symphony in C: Carbon and the Evolution of (Almost) Everything. The book and symphony celebrate carbon with movements inspired by four classic elements of Greek mythology – earth, air, fire, and water.

DCO convened an international conference, Deep Carbon 2019: Launching the Next Decade of Deep Carbon Science, at the National Academy of Sciences, Carnegie Institution for Science, and the Smithsonian Institution in Washington, DC from 24–26 October 2019. Many of the synthesis products described above were featured at the conference, which celebrated a decade of discovery and a roadmap to the future. Close to 300 members of DCO’s international community convened for a lively program that featured lightning talks, panel discussions, keynote lectures, oral and poster presentations, workshops, interactive ePosters, DCO Cinema, a photo gallery, public events, and virtual reality. 

Special thanks to Marie Edmonds and Isabelle Daniel, for their extraordinary service as chair of DCO Synthesis Group 2019 and chair of the Deep Carbon 2019 Science Program Committee, respectively. The future is bright for deep carbon science.

Deep Carbon: Past to Present Synthesizes a Decade of DCO Research
From diamonds to volcanic degassing to the deep biosphere and more, scientists within the Deep Carbon Observatory have covered a lot of ground since the initiative’s start ten years ago. To synthesize what this work reveals about the functioning of our planet and to point out new directions for the next generation of deep carbon research, DCO scientists, in partnership with Cambridge University Press and with support from the Alfred P. Sloan Foundation, have published the open-access book, Deep Carbon: Past to Present. DCO members Beth Orcutt (Bigelow Laboratory for Ocean Sciences, USA), Isabelle Daniel (Université Claude-Bernard Lyon 1, France), and Rajdeep Dasgupta (Rice University, Houston, USA) edited the book, and more than 100 international authors contributed to its 20 chapters.

Nature Deep Carbon Collection Showcases DCO Research
Some of the most exciting discoveries made by DCO researchers in the last ten years have been reported on the pages of Nature journals. Nature has compiled these papers, and a series of commissioned review articles, into a special Deep Carbon collection that reflects the breadth of research occurring within the four research communities: Extreme Physics and Chemistry, Reservoirs and Fluxes, Deep Energy, and Deep Life. Through sponsorship by DCO, many of the articles in the collection will be freely available for one year after publication. Marie Edmonds (Cambridge University, UK), co-chair of the Reservoirs and Fluxes Community Scientific Steering Committee and chair of the Synthesis Group 2019, spearheaded this effort. Read more...

Elements Special Issue: When the Carbon Cycle Went Awry
For ten years, DCO scientists have advanced our understanding of the amounts of carbon within different parts of Earth and its movement between different reservoirs, both today and through deep time. Much of this work has refined our estimates of the “steady-state” carbon cycle, but Earth wasn’t always so steady. Brief, violent periods in Earth’s history often coincided with serious disturbances to the carbon cycle, which played an outsized role on the evolution of the planet and its life forms. In a special, open-access issue of Elements, DCO collaborators investigate major, rapid shifts in the carbon cycle, including their impact on Earth and contribution to mass extinctions. DCO Reservoirs and Fluxes Community members Celina Suarez (University of Arkansas, USA), Marie Edmonds (University of Cambridge, UK), and Adrian Jones (University College, London, UK) edited the collection.

All Kimberlites Erupted from the Same Deep Reservoir
Compared to other types of volcanic rocks that erupt at Earth’s surface, kimberlites are unique. They come from the deeper parts of the mantle, contain much higher amounts of carbon dioxide and other volatile compounds than most volcanic rocks, erupt rapidly and violently, and often carry diamonds. Kimberlites are also surprisingly consistent – so consistent that a new study proposes that all kimberlite eruptions came from the same place, deep within Earth. DCO Reservoirs and Fluxes Community members Andrea Giuliani (ETH Zurich, Switzerland) and Graham Pearson (University of Alberta, Canada), with colleagues at the University of Melbourne in Australia and Durham University in the United Kingdom, looked at hundreds of kimberlite samples of different ages and geographic locations. In a new paper, published in Nature, they show this primitive, isolated reservoir remained unchanged until about 200 million years ago, around the same time that the supercontinent Pangaea was breaking up. The study is the first to use isotopes, which are atoms of the same element with different numbers of neutrons, to see how kimberlites have changed over time on a global scale. Read more...

An Inside Look at Carbon in Earth’s Interior
More than 50 DCO scientists contributed to a special American Geophysical Union Monograph, Carbon in Earth’s Interior. The book brings together research from mineral physics, materials science, petrology, and geochemistry. Chapters feature new work on the behavior of carbon in minerals, fluids, and melted rocks under the extreme conditions that occur within Earth’s interior. The co-chairs of the Extreme Physics and Chemistry community, Craig Manning (University of California, Los Angeles, USA) and Wendy Mao (Stanford University, USA), along with Jung-Fu Lin (University of Texas, USA) edited the monograph. The book will be available in December 2019. Read more...

Symphony in C: A Carbon Symphony Debuts
The Royal Scottish National Orchestra is bringing composer David Earl’s 2019 creation, Symphony in C: A Carbon Symphony, to musical life for the very first time. Following live recording sessions on 24–25 October 2019 in Glasgow, Scotland, a recorded version will be available to the public in December. Earl completed the symphony in March 2019 after being inspired in 2018 by the manuscript for Robert Hazen’s book, Symphony in C: Carbon and the Evolution of (Almost) Everything. In the book, published in May 2019, Hazen framed the complex and integral role of elemental carbon in life and on Earth as a symphony with movements inspired by four classic elements of Greek mythology – earth, air, fire, and water.
