Letter from the Director
The Deep Carbon Observatory had a banner year in 2016 as summarized in the Deep Carbon Observatory 2016: Year in Review. Prepared by the DCO Secretariat, this slide presentation highlights DCO’s crosscutting activities and Science Community accomplishments. It also features early career scientists, who embody the future of deep carbon science.
DCO seeks your input as it plans for the future. DCO launched Task Force 2020, chaired by Claude Jaupart (IPGP, France), to sustain and build upon the momentum and impact of DCO. To hear from the community directly, TF2020 is distributing a questionnaire to all members of the DCO Science Network. Please take the time to provide your input and help ensure the future of international, collaborative research in deep carbon science.
This year, DCO will be well represented at the Goldschmidt Conference in Paris, France from 13-18 August 2017, with more than 20 sessions of special interest to DCO. Please consider submitting an abstract to one of these sessions, such as “Deep Carbon” and “Reactions in Earth’s Carbon Cycle from the Surface to the Center.” The abstract deadline is 1 April 2017.
We invite all members of the DCO community to submit nominations for the DCO Emerging Leader Awards.
Congratulations to DCO colleagues who will be honored at Goldschmidt 2017. Eiji Ohtani (Tohoku University, Japan) will receive the Harold Urey Award, recognizing outstanding contributions advancing geochemistry over a career. Shuhei Ono (MIT, USA) will deliver the Paul W. Gast Lecture, which honors a mid-career scientist for outstanding contributions to geochemistry. Bernard Marty (CRPG Nancy, France) has begun his term as president of the European Association of Geochemistry, which co-organizes the Goldschmidt Conference.
We are optimistic that the successes of 2016 will continue through the new year and beyond.

Deep Carbon Degassing Measurements Help Explain Unrest at Campi Flegrei
Volcanoes are enigmatic and largely unpredictable. As they become more active, scientists track underground phenomena using a variety of measurements. Increases in seismic activity and ground deformation often indicate impending volcanic eruptions. Work from DCO’s DECADE (Deep Earth Carbon Degassing) initiative suggests measuring volcanic gas emissions is also a powerful way of understanding the mechanisms driving changes in volcanic activity. Over the last ten years, ground uplift at Campi Flegrei, an enormous caldera in Italy, resulted in intense scientific scrutiny of this reawakening volcano. DECADE’s Giovanni Chiodini (Istituto Nazionale di Geofisica e Vulcanologia, Bologna, Italy) and colleagues began collecting gas samples from Solfatara, an active fumarolic field within the 12km-wide caldera, to analyze the deep processes potentially controlling new activity. In a paper published recently in Nature Communications, Chiodini et al lay out a model for magma degassing and decompression, which could explain the ongoing Campi Flegrei unrest. Read more...
Deep Mantle Chemistry Surprise: Carbon Content not Uniform
Even though carbon is one of the most abundant elements on Earth, it is actually very difficult to determine how much of it exists below the surface in Earth’s interior. Research by Deep Carbon Observatory scientists Marion Le Voyer and Erik Hauri (Carnegie Institution for Science, USA), Katherine Kelley (University of Rhode Island, USA), and Elizabeth Cottrell (Smithsonian Institution, USA) has doubled the world’s known quantities of mantle carbon. Their findings, based on analyses of crystals containing mantle magma samples, are published in Nature Communications. Read more...
Explaining Abnormal Sound Velocities of Carbonates in Earth’s Mantle with Extreme Physics and Chemistry
Earth’s interior is a dynamic mixture of minerals and crystals. Under the influence of extreme temperatures and pressures these mixtures move around, transporting deep reservoirs of carbon throughout the mantle. Understanding how different minerals respond to changes in temperature and pressure requires a combination of theoretical and experimental approaches, and is a focus of DCO’s Extreme Physics and Chemistry Community. In a new paper, published in the journal Physical Review Letters, DCO’s Afu Lin (University of Texas Austin, USA) and his graduate students use a new diamond anvil cell apparatus to probe the elastic properties of iron and magnesium carbonates at conditions of the lower mantle.

DCO Scientific Collections Browser Now Available in the DCO Data Portal
For many DCO scientists, collecting and storing field samples is a critical aspect of their work. Acquiring new physical samples can be expensive and difficult, especially in situations where sample collection requires large research expeditions to remote locations. By utilizing existing sample collections, scientists can save time, money, and effort that would otherwise be spent collecting samples from the field. To help scientists more easily access repository information, a recent DCO-funded project aimed to collect information on scientific collections in one easily accessible location. Project leader Beverly Blakeney DeJarnett (University of Texas at Austin, Bureau of Economic Geology, USA) compiled over 100 international and US geologic and bio‐geologic scientific collections relevant to the DCO community. Using DeJarnett’s database, the DCO Data Science Team produced a searchable browser of scientific collections on the DCO Data Portal. Read more...
