Letter from the Director
Congratulations to DCO’s Craig Manning (University of California, Los Angeles, USA) and Bernard Marty (Centre de Recherches Pétrographiques et Géochimiques, France), who are this year’s recipients of AGU’s Norman L. Bowen Award and Lecture. Manning is chair of the DCO Executive Committee and DCO’s Extreme Physics and Chemistry Community. Marty served as the inaugural co-chair of DCO’s Reservoirs and Fluxes Community, and his research indicating that comets made significant contributions to early Earth is featured in the June issue of the DCO newsletter. Manning and Marty will present their Bowen lectures at the 2017 AGU Fall Meeting in a session convened by Anat Shahar (Carnegie Institution for Science, USA) and Marie Edmonds (University of Cambridge, UK). Shahar serves on DCO Task Force 2020 and Edmonds is chair of DCO Synthesis Group 2019 and co-chair of DCO’s Reservoirs and Fluxes Community. It is fitting that an award named in honor of Bowen – who is widely known for his highly influential book, Evolution of Igneous Rocks (1928) – will be presented to DCO leaders who are conducting pioneering research on the “evolution of carbon in Earth.” Bowen’s reaction series, which remains widely used today, provides inspiration for a DCO synthesis project, Earth in Five Reactions. Coming full circle, Bowen spent most of his career at the Geophysical Laboratory of the Carnegie Institution for Science, which hosts the Secretariat of the Deep Carbon Observatory.
Congratulations also are in order to DCO’s Alberto Striolo and Adrian Jones (University College London, UK) for their €10 million grant from the European Commission’s Horizon 2020 program to support Science 4 Clean Energy (S4CE), a multidisciplinary consortium involving more than 20 organizations in Europe. S4CE will build on existing international collaborations to integrate innovative technologies, including instrumentation developed by DCO. Other DCO scientists involved in the project include Isabelle Daniel (Université Claude Bernard Lyon1, France), Bénédicte Ménez (Institut de Physique du Globe de Paris, France), David Cole (The Ohio State University, USA), and Edward Young (University of California, Los Angeles, USA). We look forward to providing additional information about S4CE after the new consortium holds its initial organizational meeting.
Last but not least, we are grateful to the Alfred P. Sloan Foundation for its generous support to the Deep Carbon Observatory. We are delighted that DCO's Deep Energy Community and Reservoirs and Fluxes Community have received grants that support their extraordinary research for the next two years.
In light of a plethora of recent DCO publications, honors, and grants, I have great confidence in a bright future for deep carbon science.

Comets Made Significant Contributions to Early Earth
When early Earth was in the final stages of formation from solar system debris, comets likely crashed into the planet, potentially bringing along water, nitrogen, trace gases, and even organic carbon. These contributions may have been instrumental in setting the stage for life to evolve on Earth, but the extent and nature of these cometary materials have long been a source of debate. A new analysis of comet ice and dust collected by Rosetta, a spacecraft launched by the European Space Agency, finds that comets made a significant contribution to Earth’s atmosphere. Bernard Marty (Centre de Recherches Pétrographiques et Géochimiques, France), a member of the DCO Reservoirs and Fluxes Community and Scientific Steering Committee, in collaboration with 29 other researchers from six countries, made a detailed analysis of the trace gas xenon in the cloud surrounding the 67P/Churyumov-Gerasimenko comet, sampled by Rosetta. In a new paper in the journal Science, the group reports that based on the characteristics detected in 67P’s xenon, they estimate that about 22% of xenon in Earth’s atmosphere came from comets. Considering that comets are also rich in organic carbon, these findings suggest they may have carried substantial amounts of carbon and other volatile compounds to early Earth. Read more...
New Tool for Tracking Bathyarchaeota in Marine Sediments
The Bathyarchaeota are a widespread and abundant group of Archaea commonly found in marine sediments. Researchers suspect that they play an important role in carbon cycling, but the details of their activities have thus far remained elusive. Scientists cannot, as yet, culture Bathyarchaeota in the lab, and their incredibly small size makes them difficult to visualize under the microscope. In a new paper in Environmental Microbiology Reports, Fengping Wang (Shanghai Jiao Tong University, China) and colleagues report an improved method for detecting and quantifying Bathyarchaeota in the environment. They demonstrated that their method detects a wider variety of Bathyarchaeota subgroups than previously possible and that it can help uncover relationships between abundance and environmental conditions. Wang is a member of the Deep Life Community and Scientific Steering Committee. This work is part of a DCO-supported pilot project to understand the Archaea playing significant roles in carbon cycling in marine sediments. Read more...
A New Source of Hydrocarbons in the Deep Carbon Cycle
Acetate is a simple two-carbon molecule found almost everywhere in the surface environment. It can be found dissolved in oceans, lakes, and oil field brines, and is part of numerous biochemical reactions in cells; fermentative bacteria especially excrete acetate in the form of vinegar. Due to its ubiquity on the surface, acetate could end up in the deep subsurface through subduction, a process where at the boundaries of tectonic plates, one edge sinks beneath the other into the mantle. New research suggests that acetate also may play an important role in the deep carbon cycle by contributing to the formation of hydrocarbons. A new study finds that acetate dissolved in water can transform into the four-carbon hydrocarbon isobutane at the high temperatures and pressures of subduction zones. Isobutane does not mix well with water, and instead forms an oily liquid that might migrate independently in the subduction zone environment. The discovery represents a novel source of deep hydrocarbons and a new way for carbon to move through the subsurface. New experimental results in this study are by Fang Huang and Dimitri Sverjensky (Johns Hopkins University, USA) and Chair of the Deep Energy Community, Isabelle Daniel, with her lab members Hervé Cardon and Gilles Montagnac (all at Université de Lyon, France). The researchers report their findings in a new paper in Nature Communications. Read more...
Researchers Illuminate How Ice Melts, One Nanosecond at a Time
Ice crystals melt into water within glaciers, on icy roads, and in cold drinks, but scientists know little about the fine details of this process. Now, researchers affiliated with the European Laboratory for Non-Linear Spectroscopy (LENS) have developed technology for monitoring thawing ice from one nanosecond after melting begins. The work will enable the researchers to study the formation of natural gas hydrates, ice-methane compounds, which form deposits on the sea floor. DCO Extreme Physics and Chemistry Community members Margherita Citroni, Roberto Bini (both at Università di Firenze, Italy), Samuele Fanetti (LENS, Italy), and colleagues, developed ultra-fast laser spectroscopy techniques to superheat an ice crystal under pressure and then detect the melting process at high temporal resolution. The study is the first to monitor melting and crystal formation at a time scale of nanoseconds to milliseconds. The researchers report their findings in a new paper in Proceedings of the National Academy of Sciences. Read more...
Sample Registration Made Easy
Imagine the possibilities if all physical samples collected in the Earth Sciences were registered in a global online catalog that is connected to the scientific literature: With one click of your mouse you could find all the publications that mention a specific sample. With a catalog like this, you could search for and easily find all the physical samples you might need to answer a pressing research question and find other samples with similar properties - with supporting geospatial, temporal, and compositional data - and figure out where each sample is stored. And, picture having all the data for each sample available and in a standard, electronic format. “Sample registration has become so easy that physical samples really can be made accessible to others researchers without much effort,” says Reservoirs and Fluxes Scientific Steering Committee member Kerstin Lehnert, (Columbia University, USA), who has built and operated the System for Earth Sample Registration (SESAR) with funding from the National Science Foundation. SESAR Data Curator Megan Carter has recently created a series of videos, explaining exactly how to register physical samples. Read more...

DCO Reservoirs and Fluxes Call for Proposals: Tectonic Fluxes of Deep Carbon
The Reservoirs and Fluxes Community of the Deep Carbon Observatory invites proposal applications (with a budget up to US $50,000) to synthesize observations and data on the pathways and magnitudes of Tectonic Fluxes of Deep Carbon. A competitive proposal should quantitatively describe pathways of carbon mobility that are: (A) triggered and/or mediated by tectonic activity, and (B) should focus on carbon fluxes that are on pathways directly from the mantle or crust into the oceans and atmosphere and vice versa (ingassing). They should not include the obviously volcanic examples of diffuse degassing, or transport of carbon into the oceans by river systems. A quantitative global tectonic carbon flux, and its uncertainty, is a required final outcome of the study to be funded. Data used in the quantification of fluxes in the project will be archived with the assistance of the DCO Data Science Team, and made accessible to the wider community within one year of the expiration of the project, in compliance with DCO Data Policy. The proposal should consist of a cover page, a research statement (no more than three pages, single spaced 12-point font, bibliography excluded), a budget (not exceeding US $50,000), and CVs of the project participants. Please email proposals to Erik Hauri by 15 August 2017; the award will be made with a starting date of 15 September 2017 and must conclude by 31 May 2018.
Beckman Young Investigator Program
The Beckman Young Investigator (BYI) Program provides research support to the most promising young faculty members in the early stages of their academic careers in the chemical and life sciences, particularly to foster the invention of methods, instruments, and materials that will open up new avenues of research in science. Projects proposed for the BYI program should be truly innovative, high-risk, and show promise for contributing to significant advances in chemistry and the life sciences. They should represent a departure from current research directions rather than an extension or expansion of existing programs. Proposed research that cuts across traditional boundaries of scientific disciplines is encouraged. Proposals that open new avenues of research in chemistry and life sciences by fostering the invention of methods, instruments, and materials will be given additional consideration. Application deadline: 14 August 2017
Deep Life Cultivation Internship Program
DCO's Deep Life Community (DLC) realizes that the majority of deep microbial life has been resistant to cultivation in the laboratory, which complicates the characterization of physiological characteristics of deep community members. However, recent studies using bioreactor-cultivation techniques, under high pressure and/or temperature, have resulted in successful enrichment of previously uncultivable archaeal and bacterial components that mediate biogeochemical carbon cycling in the deep subsurface. To maintain and strengthen cultivation strategies in future deep life missions, the DLC will support early career researchers to visit some key laboratories (Inagaki - Kochi, Japan, Bartlett - La Jolla, USA, and others) to learn and practice newly developed cultivation and cultivation-dependent molecular/biogeochemical techniques, using samples from the DLC’s field missions.

Carbon degassing through volcanoes and active tectonic regions
Guest editors: Tobias Fischer, Alessandro Aiuppa, Marie Edmonds
Carbon exchange between Earth’s interior, the atmosphere, and hydrosphere plays a fundamental role in planetary and atmospheric evolution. The main identified pathways of carbon release from the solid Earth are volcanoes and regions of diffuse degassing in tectonically active areas, yet the quantities, sources, variability, and processes of carbon release remain poorly constrained. This special theme is on the observations, quantification and models of carbon transfer from Earth’s crust and mantle to the surface. It includes emphasis on temporal and regional degassing variability, utilization of carbon degassing as a volcano and earthquake monitoring tool, and interdisciplinary approaches to quantifying carbon emissions. The theme includes results from the Deep Carbon Observatory Deep Earth Carbon Degassing (DCO-DECADE) initiative as well as contributions from the broader community interested in carbon exchange on Earth. If you are interested in contributing to this special issue, please send an email to Tobias Fischer, Alessandro Aiuppa, or Marie Edmonds, including names of authors and a title. Author list and title do not need to be finalized to express interest.
