Letter from the Director
DCO scientists reported important discoveries about abiotic synthesis of complex organic molecules on Earth and Mars. A remarkable paper in Nature provides evidence for abiotic synthesis of amino acids in the oceanic lithosphere. “Demonstrating the potential of fluid-rock interactions in the oceanic lithosphere to generate amino acids abiotically gives credence to the hydrothermal theory for the origin of life, and may shed light on ancient metabolisms and the functioning of the present-day deep biosphere,” according to DCO scientists Bénédicte Ménez, Céline Pisapia, Muriel Andreani, Frédéric Jamme, Matthieu Réfrégiers, Laurent Richard, and collaborators.
DCO members Andrew Steele, Erik Hauri, Richard Wirth, Marc Fries, Karyn Rogers, and colleagues documented organic synthesis on Mars by electrochemical reduction of carbon dioxide. “Even if life doesn’t exist on Mars, this study is telling us a huge amount of information on how life potentially started on Earth,” said Steele. “This reaction is probably typical to early Earth, Europa, Enceladus, and other solar system bodies.”
Tectonic degassing of carbon dioxide remains an enigmatic part of the deep carbon cycle. A new paper by DCO members Giancarlo Tamburello, Giovanni Chiodini, and colleagues demonstrates global-scale control of extensional tectonics on CO2 earth degassing.
The inaugural symposium of the International Center for Deep Life Investigation (IC-DLI) at Shanghai Jiao Tong University was held in conjunction with a DCO Deep Life Community meeting in Shanghai, China. The IC-DLI will continue deep life research beyond the culmination of the DCO decadal program in 2019. Fengping Wang hosted the DCO meeting in Shanghai and is co-leader of the new IC-DLI.
We are profoundly grateful to the Alfred P. Sloan Foundation for its continued support of the Deep Carbon Observatory, including two new grants that support synthesis research on "Carbon Down Under" and Carbon Mineral Evolution.
Congratulations to DCO Executive Committee members Peter Fox and Paula Olsiewski on their election as Fellows of the American Association for the Advancement of Science.
Finally, DCO will have a large presence at the 2018 AGU Fall Meeting, which will feature numerous deep carbon presentations in a wide range of sessions, including more than 50 presentations about results from the Oman Drilling Project. I look forward to seeing many of you at the conference in Washington, DC, during the week of 10 December.

Earth’s First Amino Acids May Have Come From Oceanic Crust
As a graduate student at the University of Chicago in the early 1950s, Stanley Miller attempted to recreate the atmosphere of early Earth in a round flask. He mixed water vapor, methane, hydrogen, and ammonia, and zapped it with electricity to simulate lightning. The resulting chemical reactions yielded a collection of amino acids, showing that a handful of gases could provide the building blocks to create proteins. Yet in the decades since Miller’s pioneering experiment, scientists have pointed out that his gas composition likely did not match the primitive atmosphere and cast doubt on the possibility that the amino acids in his dilute "primordial soup" could concentrate and evolve into more complex compounds. But, no one since had found abiotic amino acids created independently of life from terrestrial geochemical processes, preserved in Earth’s geological record. Now, DCO Deep Energy Community members have discovered the “geological mirror” of Miller’s atmospheric experiments and found amino acids that formed in mantle-derived rocks, called serpentinites, from the subseafloor. Bénédicte Ménez (Institut de Physique du Globe de Paris and Université Paris Diderot, France), Céline Pisapia, (Institut de Physique du Globe de Paris, Université Paris Diderot, France, and Synchrotron SOLEIL, France), Muriel Andreani (Laboratoire de Géologie de Lyon, France), Frédéric Jamme, Matthieu Réfrégiers (both at Synchrotron SOLEIL, France), and Laurent Richard (Nazarbayev University, Kazakhstan) worked with colleagues Alain Brunelle, Quentin Vanbellingen (Institut de Chimie des Substances Naturelles, France) and Paul Dumas (Synchrotron SOLEIL, France). The researchers merged several high-resolution microscopy techniques to identify amino acids associated with clays in serpentinites. Their presence lends support to the theory that Earth’s first life may have arisen within hydrothermal systems, beneath vents on the seafloor. They describe their discovery in a new paper in Nature.

Martian Organic Molecules Came From Natural “Batteries”
In 2012, NASA’s Curiosity rover scooped up a handful of Martian soil and analyzed its contents to find several hydrocarbons. That same year, millions of miles away on Earth, researchers discovered similar organic compounds in 10 meteorites, blasted off of the red planet by asteroid or comet impacts, which then fell to Earth. Now, the researchers think they know how these compounds originally formed on Mars. DCO members Andrew Steele (Carnegie Institution for Science, USA), Erik Hauri (deceased, formerly of Carnegie Institution for Science, USA), Richard Wirth (GFZ German Research Centre for Geosciences, Germany), Marc Fries (NASA Johnson Space Center, USA), and Karyn Rogers (Rensselaer Polytechnic Institute, USA) and colleagues used high-resolution transmission electron microscopy to take a nano-scale look at three of those 10 Martian meteorites, and published their work in Science Advances. Based on the mineral patterns, they propose that salty fluids on Mars reacted with the mineral magnetite. The resulting electrochemical reactions transformed dissolved inorganic carbon in the fluids into complex organic molecules. These reactions occur independently of life, but they may be one possible way to generate organic compounds that support the first life forms on potentially habitable planets. Read more...
Clumps of Organic Carbon Found Within Serpentinites
In theory, the process of serpentinization, where seawater infiltrates and reacts with the mantle rock peridotite, should generate clumps of organic carbon called condensed carbonaceous matter (CCM). Scientists have predicted that CCM forms during serpentinization in the absence of life, based on thermodynamic calculations. But until recently, researchers had found only smaller organic compounds, like methane, short hydrocarbons, and organic acids, spewing from serpentinizing sites. In a new study of ancient rocks that were once at the bottom of the Tethys Sea, a group of DCO Deep Energy Community members have identified three types of CCM that form during serpentinization. Each type is associated with a different assemblage of low-temperature minerals. Marie Catherine Sforna (formerly at the University of Modena e Reggio Emilia, Italy, now at University of Liège, Belgium), Daniele Brunelli (University of Modena e Reggio Emilia, Italy), Bénédicte Ménez, Céline Pisapia, (both at Institut de Physique du Globe de Paris, and Université Paris Diderot, France), and Valerio Pasini (Institut de Physique du Globe de Paris, France, and University of Modena e Reggio Emilia, Italy) report the discovery in a new paper in Nature Communications.

Spreading Faults Create New Deep Carbon Leaks
Since at least the 1970s, scientists have noticed that areas with frequent earthquakes also tend to have springs that bubble with carbon dioxide. They reasoned that slipping tectonic plates opened small rifts in the crust, like stretching an accordion, which lets deep carbon dioxide seep into aquifers and up to the surface. But tracking and measuring the gas that escapes from these faults, called Earth degassing, is an enormous task. Researchers have only performed more detailed studies in a few locations: the Himalayas, central Italy, and the East African Rift. To see if the relationship between shifting tectonics and carbon dioxide release holds true worldwide, DCO Reservoirs and Fluxes Community members Giancarlo Tamburello and Giovanni Chiodini (both at Istituto Nazionale di Geofisica e Vulcanologia, Italy) with INGV colleagues Silvia Pondrelli and Dmitri Rouwet, analyzed global geological databases of earthquakes, volcanic eruptions, and carbon dioxide-rich springs. In a new paper in Nature Communications, they report a correlation between the locations of carbon dioxide leaks and active faults, especially those that create openings in the crust. These findings could inform future estimates of how Earth degassing has impacted atmospheric carbon dioxide levels and global temperature in the past. Read more...

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.
