Letter from the Director

The Deep Carbon Observatory, Carnegie Institution for Science, and the broader scientific community are shocked and saddened by the sudden loss of Erik Hauri at age 52. Erik was at the zenith of his career when his contributions were cut short by his untimely death on 5 September 2018. Erik’s selfless leadership of DCO—as a member of the Executive Committee and co-chair of the Reservoirs and Fluxes Community—focused on answering the most important scientific questions and promoting early career scientists.
DCO researchers continued to publish novel scientific results this month. Marie Edmonds (University of Cambridge, UK), Tamsin Mather (University of Oxford, UK) and Emma Liu (University of Cambridge, UK) discovered a distinct metal fingerprint in arc volcanic emissions. They propose that volcanic metal emissions are controlled by magmatic water content and oxidation state.
Renbiao Tao (Université Claude Bernard Lyon, France) and an international team of scientists reported the formation of abiotic hydrocarbons by reduction of carbonate in subduction zones. The team observed the identical mineral assemblage associated with hydrocarbons in both naturally carbonated eclogite and high-pressure experimental run products, pointing toward the same formation mechanism.
Based on high-resolution spectroscopy and microscopy, Bénédicte Ménez (Institut de Physique du Globe de Paris, France) and colleagues demonstrated that organic carbon is directly involved in low-temperature serpentinization reactions, which can produce molecular hydrogen and abiotic organic compounds that sustain microbial ecosystems in the oceanic lithosphere.
Speaking of serpentinization, Susan Lang (University of South Carolina, USA) and William Brazelton (University of Utah, USA) are leading a deep-sea expedition to the Lost City hydrothermal field aboard research vessel Atlantis, along with the ROV Jason team from the Woods Hole Oceanographic Institution. The remotely operated vehicle will collect large volumes of hydrothermal fluids and rock samples, which will help establish connections between serpentinization and microbial life. You can follow the expedition online.
Lastly, a mathematical model developed by James Bradley, Jan Amend, and Douglas LaRowe (University of Southern California, USA) considers physiological transitions between active and dormant states of microorganisms buried in marine sediments. The researchers showed that microorganisms can survive in a state of suspended animation over geologic time scales by slowly consuming nearby carbon compounds.
We encourage you to nominate early career scientists for DCO Emerging Leader Awards. The deadline has been extended until 12 October.

Different Volcano Types Show Their Metal
Living organisms have a complex relationship with metals. In small amounts, some metals are vital nutrients for cells, while others are highly toxic. For most of Earth’s history volcanoes have gradually brought metals from deep Earth to the surface. A new study published in Nature Geoscience shows that we can learn a lot about a volcano from the metals it spews into the air. DCO Reservoirs and Fluxes Community members Marie Edmonds (University of Cambridge, UK), and Tamsin Mather (University of Oxford, UK), along with Emma Liu (University of Cambridge, UK) looked at the metals emitted from two volcano types. They found distinct differences in the composition of metals from hotspot volcanoes like those found in Hawaii, where a superheated plume from deep in the mantle causes an isolated eruption, and arc volcanoes, which occur along the edges of subducting tectonic plates. Their findings suggest that the type of volcanoes erupting on Earth when life first began may have influenced the metals that early cells encountered as they evolved. Read more...

Organic Carbon Shapes Minerals and Metals at Low Temperature in Serpentinite Rocks
When exhumed mantle material creates new seafloor along mid-ocean ridges, seawater seeps into cracks and interacts with the rock to make serpentine minerals. These serpentinization reactions generate hydrogen and small organic compounds, supporting microbes colonizing the pores and cracks. New findings suggest that the remnants of these organic compounds, whether from biological or abiotic origins, take an active role in how serpentinization reactions proceed. DCO Deep Energy Community members Bénédicte Ménez (Institut de Physique du Globe de Paris, France) and Daniele Brunelli (University of Modena e Reggio Emilia, Italy), and Deep Life Community member François Guyot (Muséum National d’Histoire Naturelle, France) used high-resolution microscopy techniques to visualize the fractures and mineral boundaries in serpentinite rocks collected from the Mid-Atlantic Ridge. The researchers discovered that organic carbon causes unusual bead-like spheres of the mineral serpentine to form, and also traps metals like cobalt, manganese, and nickel. The findings, published in a new paper in Lithos, suggest that organic carbon may play an active role in low-temperature serpentinization and in the formation of some supergene ore deposits, which occur close to the surface.

Under the Right Conditions, Subduction Zone ‘Factories’ May Manufacture Abiotic Hydrocarbons
Subduction zones, where the edge of one tectonic plate slips beneath another, have earned the reputation as “factories.” Carbon from bits of ocean crust, sediments, and pieces of mantle enter the subduction zone, which recycles some carbon back into the atmosphere through volcanoes, and sends some into the mantle for further processing. Accounting for what’s coming in and out of the subduction zone factory is vital to understanding the finer points of the deep carbon cycle. In a new paper in Geochimica et Cosmochimica Acta, DCO members present evidence that when carbonates and water within an ocean plate enter the subduction zone factory, they transform into graphite and light hydrocarbons, such as methane, ethane, and propane. Renbiao Tao (Université Claude Bernard Lyon, France, formerly of the Carnegie Institution for Science, USA), Lifei Zhang, Meng Tian, Jianjiang Zhu (all at Peking University, China), Vincenzo Stagno (University of Rome, Italy), and Yingwei Fei (Carnegie Institution for Science, USA) examined rock samples from the Southwest Tianshan subduction zone in China. The researchers discovered bubbles of hydrocarbons trapped in eclogite, a metamorphic rock that forms at high pressure from the material in subducted ocean plates. The researchers also simulated the subduction environment in the lab, using a high-pressure multi-anvil press, to show that carbonate and water can react under the conditions found in nature to form a mix of light hydrocarbons and graphite.

How Microbes Survive When Buried Alive
For most microbes that settle into marine sediments, there’s nowhere to go but down. They become buried alive beneath new layers of ocean detritus, potentially laying low for tens of millions of years, with little access to food or energy sources. Estimates suggest that more microbes live in marine sediments than in all of the world’s soil, but researchers know little about how they survive in this dark, sinking habitat. Now, a new model developed by DCO researchers predicts how microbes persist at the limits of life over geologic timescales. James Bradley, Jan Amend, and Douglas LaRowe (all at the University of California, Los Angeles, USA) applied the model to look at microbial survival and metabolism in sediments in the South Pacific Gyre, a veritable desert on the ocean floor that lies between Australia and South America. In a new paper in the journal Geobiology, they show that microorganisms survive in a state of suspended animation and subsist by slowly consuming nearby carbon compounds. Despite their low activity levels, these dormant microbes are responsible for breaking down more than 99 percent of the organic carbon in these ancient sediments. Read more...

A Return to the Lost City: This Time it’s Microbial
For the first time since 2008 U.S. scientists will thoroughly explore the Lost City hydrothermal field with a dedicated expedition entitled Return to Lost City 2018. The field is located on the Atlantis Massif, a dome of peridotite rock from the mantle near the Mid-Atlantic Ridge. On the massif, dozens of chimneys spew alkaline fluids rich in methane and hydrogen, which support a diverse community of microbes, mussels, snails, crustaceans, and worms. These fluids result from serpentinization reactions occurring between peridotite rock and seawater. Scientists aboard the research cruise aim to further investigate microbes living at the site, and how they consume deep carbon seeping from hydrothermal vents along the seafloor. DCO Deep Life Community members Susan Lang (University of South Carolina, USA) and William Brazelton (University of Utah, USA) lead the expedition, in collaboration with DCO members Gretchen Früh-Green (ETH-Zurich, Switzerland), Marvin Lilley, and Deborah Kelley (both at University of Washington, USA).

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.
