Letter from the Director

The Deep Carbon Observatory is ending the summer on a high note. Mt. Etna volcano in Sicily, Italy provided a stunning natural laboratory for 60 scientists from 46 institutions in 16 countries who participated in the Third DCO Early Career Scientist Workshop.  
 
Meanwhile, the Oman Drilling Project conducted two months of core logging aboard the Drilling Vessel Chikyu. Phase 1 core logging is now complete and applications for participating in Phase 2 of the Oman Drilling Project are due on 15 October 2017. 
 
DCO Deep Energy Community members Thu Le, Alberto Striolo (both of University College London, UK) and David Cole (Ohio State University, USA) proposed a novel mechanism for abiotic methane formation. They demonstrate that the effects of confinement in nanopore-controlled chemical reactions can shift thermodynamic equilibrium towards methane production. This mechanism could explain methane observed in some submarine hydrothermal vent systems.
 
Congratulations to Sergey Lobanov (State University of New York at Stony Brook, USA) for winning a Helmholtz Young Investigator Group Leaders award, which will provide €1.8 million in 2018-2023 for him to establish a new group at the GFZ German Research Centre for Geosciences (Postdam, Germany). Sergey is also the lead author of a recent paper on tetrahedrally bonded calcium carbonate that exists at lower mantle pressures.
 
The memory of Katrina Edwards is honored by a special issue of Frontiers in Microbiology on “Recent Advances Geomicrobiology of the Ocean Crust,” which contains contributions from numerous DCO scientists.
 
Looking to the future, we encourage you to nominate candidates for the DCO Emerging Leader Awards by 29 September 2017 as we begin fall on a similarly high note as we have ended summer.

Special Issue of Frontiers in Microbiology: Recent Advances in Geomicrobiology of the Ocean Crust
A new special issue of Frontiers in Microbiology entitled Recent Advances in Geomicrobiology of the Ocean Crust features papers from numerous DCO scientists. The special issue includes papers published in the past two years that focus on the diversity and metabolism of microbes living beneath the seafloor, and how the interactions between water, rock, and microbes in the ocean crust contribute to global biogeochemical cycles. Deep Life Community members Beth Orcutt (Bigelow Laboratory for Ocean Sciences, USA) and Jason Sylvan (Texas A&M University, USA), along with Cara Santelli (University of Minnesota, USA) co-edited the special issue. The issue is dedicated to the memory of Katrina J. Edwards (1968–2014), a pioneering geomicrobiologist who initiated early investigations into microbes that live beneath the seafloor. Read more...

Researchers Discover the ‘Diamond of Carbonate’
At the surface, pure carbon takes the form of graphite, a soft mineral composed of sheets in which every carbon atom is joined to a triangle of three others. Deep within Earth’s mantle, however, extreme temperatures and pressures convert graphite into diamond, a denser mineral where each carbon atom is joined to four other carbon atoms, forming a tetrahedral bonding geometry. Once thought unique, new research suggests that other carbon compounds may also make a similar phase shift under pressure. A new study provides strong evidence that carbon in calcium carbonate assumes a diamond-like bonding pattern in the lower mantle, as well. Sergey Lobanov (State University of New York at Stony Brook, USA, formerly at the Carnegie Institution for Science, USA where he conducted this research), a member of the DCO Extreme Physics and Chemistry Community, and fellow DCO members Alex Goncharov (Carnegie Institution for Science, USA), Naira Martirosyan (Sobolev Institute of Geology and Mineralogy, Russia), and Konstantin Litasov (Sobolev Institute of Geology and Mineralogy and Novosibirsk State University, Russia) explored the phase transition from triangular (CO3) to tetrahedral (CO4) calcium carbonate. They heated and squeezed calcium carbonate in the lab and used advanced analytic techniques to identify a chemical signature indicating that the bonding between carbon and oxygen atoms had changed and the phase shift had occurred. The researchers report their findings in a new paper in the journal Physical Review B. Read more...

What Hawaii Can Tell Us About Mantle Carbon: An Interview with Peter Barry
In a recent article in Nature Geoscience, DCO Reservoirs and Fluxes Community members Kyle Anderson and Michael Poland, both of the U.S. Geological Survey, described the results of a new way to estimate the amount of carbon deep in Earth’s mantle. They combined measurements of carbon dioxide emitted from Kīlauea, Hawaii’s most active volcano, with indirect measurements of how much magma flows into the volcano. Through modeling, they calculate that the carbon content of the mantle beneath Hawaii is about 40% higher than previous estimates. If verified, these findings could have important implications for the global carbon budget, the size of deep carbon fluxes, and historical reconstructions of Earth’s climate. Peter Barry, a noble gas geochemist at the University of Oxford, wrote a News and Views commentary to accompany the paper in Nature Geoscience. Barry is a member of DCO’s Deep Energy Community and the Reservoirs and Fluxes Community who has been active in organizing Early Career Scientist workshops and was the lead principal investigator on the Biology Meets Subduction expedition in February 2017. He talked with DCO science writer Patricia Waldron over Skype about the new paper and its significance for deep carbon research.

Mind the Gaps: Tiny Pores Encourage Methane Formation
One of the big questions in deep carbon research, which helped inspire DCO’s founding and has been championed by the Deep Energy Community, is whether underground methane forms due to the activities of subsurface microbes (biotic) or from physical and chemical reactions between fluids and minerals (abiotic). One possible source of abiotic methane is serpentinizing systems, such as hydrothermal vents. At these sites, fluids circulate within the cracks of certain mantle rocks to produce hydrogen, which can then react with carbon dioxide to form methane. While serpentinizing systems appear to be rich in abiotic methane, benchtop experiments and thermodynamic calculations have not always supported the idea that this reaction is feasible. In a new paper in the journal Scientific Reports, Deep Energy Community Members Thu Le, Alberto Striolo (both at University College London, UK), and David Cole (The Ohio State University, USA), investigate the impact of tiny pores in rocks on the generation of abiotic methane in the subsurface.

EarthByte Models Mantle Plumes Through Space and Time
According to DCO member Sabin Zahirovic (EarthByte, University of Sydney, Australia), Earth’s interior is essentially a giant, spherical lava lamp. The intense heat at the core drives plumes of mantle material up to the cooler surface where it solidifies as part of tectonic plates. Over geologic timescales, the edges of those plates eventually sink back into the mantle in a process called subduction, which contributes to convection. The churning of Earth’s interior controls the movement of the plates at the surface, which in turn regulates the balance of carbon between the atmosphere and the subsurface, moderating climate. Ultimately, it is these swirling, lava lamp-like processes that make our planet habitable. The DCO has partnered with EarthByte to support paleogeography, climate, and deep carbon research using its plate tectonic models. Modeling offers a way to extract more information from new data sets and to integrate existing Earth science data sets collected over decades. “With the DCO, we’re studying the deep carbon cycle in the deep Earth and through deep geological time,” said Zahirovic. “Now that we have this great data from the DCO community, we can start to put the pieces of the puzzle together to make sense of these Earth systems through time.” Read more...

Third Early Career Scientist Workshop Brings International Group to Mt. Etna, Italy
The Third DCO Early Career Scientist Workshop took place on the flanks of Mt. Etna volcano in Sicily, Italy, from 28 August – 2 September 2017. The workshop brought together more than 60 early career scientists from 16 countries and 46 different institutions for a week of talks, poster sessions, and field trips. Scientists gathered at the Hotel Biancaneve in the town of Nicolosi, from which participants could watch Etna’s activity at all hours of the day. For some participants, spending time on an active volcano was a completely new experience, but for others, it was business as usual. The variety in the disciplines and the backgrounds of the participants is one of the strengths of the DCO Early Career Scientist workshops, with microbiologists learning from volcanologists, geochemists from geodynamicists, and all combinations in between.

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.
