Third DCO International Science Meeting

From 23-25 March 2017, more than 150 members of the DCO Science Network met at the University of St Andrews for the Third DCO International Science Meeting. Read more about the meeting here.

Letter from the Director


The Third DCO International Science Meeting featured major advances in deep carbon science. The meeting, which took place at the University of St Andrews, Scotland from 23-25 March 2017, “flipped” meeting norms, with many early and mid-career scientists delivering oral presentations and many senior scientists giving poster presentations. This strategy provided opportunities for all participants to learn about early career scientists' research during the plenary sessions, while creating opportunities for one-on-one interactions between senior and early career scientists at the poster sessions. 
We are especially grateful to Chris Ballentine (University of Oxford, UK) for serving as chair of the Science Program Committee and Sami Mikhail (University of St Andrews, UK) for serving as local host for the Third DCO International Science Meeting. The meeting provided a glimpse of how much has been accomplished since DCO’s inception in 2009. It also served as a prelude to synthesis activities.
The Deep Carbon Observatory is dedicated to supporting the scientific and professional development of early career scientists, who embody the future of deep carbon science. We encourage DCO early career scientists to apply for exciting opportunities in Italy in summer, fall, and winter:
Third DCO Early Career Scientist Workshop at Mt. Etna, Italy
Ph.D. School on Carbon Forms, Paths and Processes in Como, Italy
International Diamond School in Bressanone, Italy, 2018
Congratulations to Maggie CY Lau (Princeton University, USA) and Yves Moussallam (University of Cambridge, UK), who received DCO Emerging Leader Awards for their outstanding contributions to deep carbon science and unique potential as future leaders of the DCO community.
We’d also like to encourage members of the DCO Science Network to propose deep carbon science technical sessions at the 2017 AGU Fall Meeting in New Orleans by 19 April 2017 and submit abstracts to the many deep carbon sessions at the 2017 Goldschmidt Conference in Paris by 1 April 2017.

First-Ever Catalog of 208 Human-Caused Minerals Bolsters Argument to Declare ‘Anthropocene Epoch’
Human industry and ingenuity has done more to diversify and distribute minerals on Earth than any development since the rise of oxygen over 2.2 billion years ago. Recent research bolsters the scientific argument to officially designate a new geological time interval distinguished by the pervasive impact of human activities: the Anthropocene Epoch. In a paper, published by American Mineralogist, a team led by Robert Hazen (Carnegie Institution for Science, USA) identifies for the first time a group of 208 mineral species that originated either principally or exclusively due to human activities. That’s almost 4% of the roughly 5,200 minerals officially recognized by the International Mineralogical Association (IMA). Read more...

Researchers Delineate Factors Controlling Formation of Subsurface Methane
The groundwaters bathing crystalline bedrock, shaped by high temperatures and extreme pressures, can have surprisingly high concentrations of methane, even in places where ancient organic carbon has transformed into graphite or other inorganic forms. Researchers are exploring the sources of this methane to figure out how it is produced and its role in the deep carbon cycle. Riikka Kietäväinen, a member of DCO’s Deep Energy and Deep Life Communities, along with Lasse Ahonen, also a member of the Deep Life Community, (both at the Geological Survey of Finland, in Espoo), and colleagues investigated factors that control methane formation at two sites in Finland: the Outokumpu Deep Drill Hole and the Pyhäsalmi copper-zinc mine, which both extend about 2.5 kilometers into Precambrian bedrock. In a new paper in Geochimica et Cosmochimica Acta, the researchers combine isotopic measurements from water, gas, and minerals sampled from the two sites with existing chemical and microbiological analyses.

Half of Carbon Transported to Mid-Ocean Ridges Remains Trapped Below
Much of the volcanic activity happening on Earth occurs where we can’t see it, in a network of mid-ocean ridges running along the bottom of the world’s oceans. As tectonic forces pull oceanic plates apart, they pull hot rocks up from the mantle. Some of these rocks melt in the process, producing magma that flows upward to fill the rift between the spreading plates with newly formed oceanic crust. Researchers thought that this process efficiently moves deep carbon, carried by the magma, and releases it into the ocean. But a new simulation study finds that up to half of the carbon initially removed from mantle rocks remains trapped below the oceanic plates. Tobias Keller (Stanford University, USA), Richard Katz (University of Oxford, UK), and Marc Hirschmann (University of Minnesota, USA), members of the DCO Reservoirs and Fluxes and Modeling and Visualization communities, simulated the global carbon output from mid-ocean ridges using a recently developed model of carbon transport in the mantle. While their simulations match existing estimates of global carbon release, they find that the carbon that doesn’t erupt crystallizes along with deep water that behaves similarly, in a layer at the base of the lithosphere, the plate-like part of Earth’s uppermost mantle. They publish their results in a recent paper in Earth and Planetary Science Letters. Read more...

Microbial Communities in Serpentinites Make the Best of a Difficult Situation
Serpentinite environments, like the Lost City hydrothermal field in the mid-Atlantic, have received much attention in recent years as potential cradles of life on Earth, and as analogs for sites that could support life on Mars. Microbes thrive on compounds released by reactions between serpentinizing minerals and seawater in hydrothermal vents. The submarine location of these sites, however, presents many challenges for scientists trying to study them. The Coast Range Ophiolite Microbial Observatory (CROMO), located in northern California, is a serpentinization site that once lay at the bottom of the seafloor. Its current landlocked location allows researchers to study the geochemistry and microbiology of a serpentinization site in great detail. In a new paper, DCO members Katrina Twing and William Brazelton, (both at University of Utah Salt Lake City, USA), Matthew Schrenk (Michigan State University, USA), Michael Kubo (SETI Institute, USA), Dawn Cardace (University of Rhode Island, USA), Tori Hoehler (NASA Ames Research Center, USA) and Tom McCollom (University of Colorado Boulder, USA) describe the geochemical factors affecting microbial communities at seven wells drilled into the freshwater aquifer within serpentinite rocks at CROMO. While the site provides easy access for scientists, it is a difficult environment for microbes. The study appears in the DCO Early Career Scientist research topic of Frontiers in Microbiology.

A New Contender for the Title of Oldest Fossil
The discovery of fossilized microbes within ancient rocks that formed around submarine-hydrothermal vents provides evidence that life existed at least 3,770 million years ago. If confirmed, these would be the earliest known microfossils on Earth. In a new paper, DCO Deep Life Community members Matthew Dodd, Dominic Papineau (both at University College London, UK) and colleagues describe microfossils discovered in the Nuvvuagittuq Belt in Quebec, Canada. These newly found ancient fossils are similar in appearance to fossils of filamentous microbes in younger rocks as well as cells in modern hydrothermal vent environments. The researchers also provide isotopic and mineral evidence supporting a biological origin of these structures. Their findings appear in the journal Nature. Read more...

A New Piece of the Global Methane Puzzle
The first cells on Earth may have feasted on the byproducts of serpentinization, reactions between water and mantle rocks that, in the presence of carbon, may generate large amounts of methane and other organic compounds. Serpentinization reactions at shallow depths are the subject of intense research interest due to their possible contributions to life’s origins, but also because they play an important role in Earth’s carbon cycle. Now, a new study suggests that these same chemical reactions occur not just at the surface, but also deep beneath Earth’s crust, under conditions of high temperature and pressure. DCO Deep Energy Community members Alberto Vitale Brovarone (Institut de Minéralogie, de Physique des Matériaux et de Cosmochimie, France) Isabelle Martinez (Institut de Physique du Globe de Paris, France), and colleagues studied rock samples from the Lanzo Massif in the Western Alps. The analysis shows that serpentinization reactions deep down can generate methane at rates that are comparable to shallow serpentinization environments. The researchers report their findings in a new paper in Nature Communications. Read more...

Extreme Heat and Pressure May Yield Hydrocarbons in Earth’s Mantle
All scientists strive to shed light on difficult questions, but researchers who study deep carbon face the additional challenge of illuminating a very dark place indeed: hundreds of kilometers beneath Earth’s surface. With the deepest boreholes reaching little farther than 12 kilometers, researchers must rely on theoretical calculations and lab simulations to understand the high-temperature and high-pressure reactions occurring deep within the mantle. In a new review in ChemistrySelects, three Deep Carbon Observatory researchers synthesize theory, computer modeling, and lab experiments to explain the chemical and physical processes that carbon undergoes in Earth’s upper mantle. Anton Kolesnikov (Gubkin Russian State University of Oil and Gas in Moscow) Vladimir Kutcherov (Royal Institute of Technology in Stockholm and Gubkin Russian State University of Oil and Gas), and John Saul (Swala Gem Traders, Arusha, Tanzania), draw on decades of research to explain the formation of hydrocarbons under “thermobaric” conditions, with extremely high temperatures and pressure levels.

Census of Deep Life Sequencing Opportunities: Request for Proposals
Since 2011, the Deep Carbon Observatory’s Deep Life Community has sponsored the Census of Deep Life (CoDL) that has supported surveys of the diversity of microbes present in several deep continental and subseafloor environments. The first surveys (2011-2012) were conducted using 454 pyrosequencing and subsequently (2013) Illumina sequencing strategies were adopted. Through this initiative, the Deep Life Community has allowed the characterization of diversity of subsurface microbial communities at numerous sites worldwide, including the subseafloor and deep continental locations from a range of geologic settings (e.g., large igneous provinces, subglacial lakes, methane hydrate-rich sediments, cratons). The Illumina platform provides increased numbers of reads for more samples at reduced cost. For DNA samples submitted to the CoDL for sequencing, proponents have the option of obtaining 400-450 nt sequences that span the V4V5 region of Bacterial and Archaeal rRNA coding regions or a greater number of reads for V6 regions that through complete overlap of forward and reverse reads allows detection of lower abundance taxa with reduced stochastic error rates. Shotgun metagenomic DNA sequencing for key samples can also be performed. This call for proposals aims to support sequencing that represents expanded analyses from ongoing Deep Life Community projects or projects that represent sites and investigators new to the DCO’s Deep Life Community. Proposal deadline: 30 April 2017

C-DEBI: Rolling call for Research Exchange proposals
C-DEBI facilitates scientific coordination and collaborations by supporting student, postdoctoral, and faculty exchanges to build, educate, and train the deep subseafloor biosphere community. We award small research exchange grants for Center participants. These grants may be used to support research, travel for presenting C-DEBI research at meetings, or travel exchanges to other partner institutions or institutions that have new tools and techniques that can be applied to C-DEBI research. We anticipate ~10 awards of $500-5000 with additional matched funds to be granted annually.
