Letter from the Director
DCO has much to celebrate as 2018 comes to a close. A DCO news release on life in deep Earth generated more than 1000 news stories in 84 countries and 30 languages, including articles in The New York Times, The Guardian, BBC, NBC, and CNN. The aggregate circulation online surpassed 1 billion people, which is one-eighth of the global population. The news coverage is timely and important, with greater awareness of DCO research empowering the next decade of deep carbon science.
Speaking of deep life, a review article in Nature Geoscience by DCO members Cara Magnabosco, Li-Hung Lin, Hailiang Dong, Malin Bomberg, Karsten Pedersen, Thomas Kieft, and Tullis Onstott provides new estimates of the number of cells and biomass of the continental subsurface.
In another paper about life in the continental subsurface, DCO members Avishek Dutta, Pinaki Sar, and colleagues explore the deep terrestrial subsurface microbiome in the Deccan traps and underlying Archean basement in India.
DCO Deep Life Community members Laura Zinke, Clemens Glombitza, Jordan Bird, Bo Barker Jørgensen, Karen Lloyd, Jan Amend, and Brandi Kiel Reese demonstrate that deep Baltic microbes have a taste for alcohol and cannibalism.
In a new paper in Geology, DCO members Adriana Dutkiewicz, Dietmar Müller, Sabin Zahirovic, and colleagues combine plate tectonic models and records of carbonate layers from scientific ocean drilling expeditions to estimate sequestration and subduction of deep-sea carbonate in the global ocean over the past 120 million years.
Congratulations to Peter Barry and Sabin Zahirovic for winning the 2018 DCO Emerging Leader Awards.
We are grateful to the large contingent of DCO scientists who gave more than 150 presentations at the 2018 American Geophysical Union Fall Meeting in Washington, DC on 14-18 December.
Finally, I want to thank all of our DCO colleagues for a great year in 2018 and best wishes for the culmination of the DCO decadal program in 2019.

Life in Deep Earth Totals 15 to 23 Billion Tonnes of Carbon—Hundreds of Times More than Humans
Barely living “zombie” bacteria and other forms of life constitute an immense amount of carbon deep within Earth’s subsurface—245 to 385 times greater than the carbon mass of all humans on the surface, according to scientists nearing the end of a 10-year international collaboration to reveal Earth’s innermost secrets. Drilling 2.5 kilometers into the seafloor, and sampling microbes from continental mines and boreholes more than 5 km deep, the team has used the results to construct models of the ecosystem deep within the planet. With insights from now hundreds of sites under the continents and seas, they have approximated the size of the deep biosphere—2 to 2.3 billion cubic km (almost twice the volume of all oceans)—as well as the carbon mass of deep life: 15 to 23 billion tonnes (an average of at least 7.5 tonnes of carbon per cu km subsurface). The work also helps determine types of extraterrestrial environments that could support life. Read more...
Undercover Cells: New Estimate of the Microbes Beneath the Continents
Scientists have proposed that the majority of microbes on Earth live in the vast, dark subsurface, but estimates of their numbers vary widely. Microbes in the subsurface might far outweigh the cells at the surface, or, they might just constitute a sizeable majority. During the past two decades, next-generation sequencing, which enables researchers to get a snapshot of a microbial community by sequencing all of the DNA in an environmental sample, has become more affordable and more widely used. Additionally, more scientists have undertaken explorations of the subsurface through coring and underground sampling. These advances are helping scientists to get a better handle on the numbers and diversity of cells in the subsurface. In a new review in Nature Geoscience, DCO members Cara Magnabosco (Flatiron Institute, USA), Li-Hung Lin (National Taiwan University, Taiwan), Hailiang Dong (Miami University, USA), Malin Bomberg (VTT Technical Research Centre of Finland), Karsten Pedersen (Microbial Analytics Sweden), Thomas Kieft (New Mexico Institute of Mining and Technology, USA), and Tullis Onstott (Princeton University, USA), and colleagues, make new estimates of the number and biomass of cells living beneath the continents. The researchers compiled cell counts and next-generation sequencing data from sampling locations around the world and used advanced analysis techniques to scale local counts to a global approximation. They estimate that 200 to 600 octillion microbes (2 to 6x1029 cells) live in the continental subsurface. Read more...
The First Steps When Water Meets Rock
When water encounters certain magnesium- and iron-rich mantle minerals, exciting things can happen. This process, called serpentinization, creates hydrogen and, at the seafloor, can lead to the formation of hydrocarbons and small organic compounds. The products of serpentinization support hydrothermal vent ecosystems and may have created conditions permissive for the origin of life. Naturally, scientists are interested in learning the finer details of how this process occurs to get closer to defining when and how life began. DCO members Tingting Liu, Siddharth Gautam, David Cole (all at Ohio State University, USA), and Eugene Mamantov (Oak Ridge National Laboratory, USA) performed computer simulations and spectroscopic analyses of fine-scale interactions between water and a type of olivine, a major rock-forming mineral in the upper mantle. In a new paper in Physical Chemistry Chemical Physics, they report that water forms three distinct layers when it comes in contact with the olivine. The simulations and measurements complement each other, improving our understanding of the structure and dynamics of water-olivine interactions, and lay a foundation for future research on serpentinization.

Deccan Traps Microbes Get By with a Little Help from Their Friends
In 1964, the Indian government completed a dam on the Koyna River to create a reservoir for a hydroelectric power plant in Maharashtra in western India. This dam lies within the Deccan Traps, an area covered with layers and layers of lava from massive volcanic eruptions nearly 65 million years ago, which now consists of an area of around 500,000 square kilometers. Three years after completion of the dam, a magnitude 6.3 earthquake rocked the area, followed by several hundred smaller quakes. To investigate the reservoir-triggered seismicity, the Indian government began a scientific deep drilling project at the site. DCO Deep Life Community members Avishek Dutta, Pinaki Sar (both at Indian Institute of Technology Kharagpur, India), and colleagues were on hand during the exploratory drilling to collect fresh cores samples from down to 1500 meters. Now, for the first time, they have sequenced the DNA of microbes living in the basalt layers of the Deccan Traps and the underlying 2.5-billion-year-old Archean basement rock. The researchers discovered that the microbes form interconnected networks to survive in this extreme and nutrient-limited environment, creating communities that are specifically adapted to the geochemistry of the host rock. The researchers report their findings in a new paper in Scientific Reports. Read more...
Deep Baltic Microbes Have a Taste for Alcohol and Cannibalism
In the last 16,000 years, the bottom of the Baltic Sea experienced good times and bad times. Shifting inputs from rivers and seawater, and advancing and receding glaciers, have affected the quantity and quality of organic matter drifting down to the seafloor. All of these changes are recorded in sediments, creating a “natural laboratory” for studying how microbial communities survive in sediments created during both rich and lean times. In a new paper in Applied and Environmental Microbiology, DCO members report that the carbon cycling in Baltic Sea sediments is more complex and cannibalistic than they had imagined. Deep Life Community members Laura Zinke (University of California Davis, USA), Clemens Glombitza (NASA Ames Research Center, USA), Jordan Bird (Indiana University, Bloomington, USA), Bo Barker Jørgensen (Aarhus University, Denmark), Karen Lloyd (University of Tennessee, Knoxville, USA), Jan Amend (University of Southern California, USA), and Brandi Kiel Reese (Texas A&M University, USA) analyzed DNA and geochemical data from Baltic Sea sediments to see how microbial communities varied, depending on whether they had received organic carbon from marine or terrestrial sources. Regardless of the food source, all communities had a complicated carbon cycle, with microbes fermenting organic compounds to make alcohol and degrading proteins from dead microbes. Read more...
Mapping the Growth of Seafloor Carbonates in Deep Time
The dominant, and yet least explored, way that carbon returns to Earth’s interior is through the accumulation and eventual subduction of layers of sedimentary carbonate rocks. These layers build up on the seafloor from the skeletons of dead marine plankton and later become buried by other sediments as they move across ocean basins due to seafloor spreading. Most of what we know about carbonate deposits comes from rock and sediment cores collected from 50 years of deep ocean drilling programs. But even these expeditions rarely drill deep enough to give a clear picture of where and how much carbonate lies buried in ocean basins. To understand how much carbon is stored away in sedimentary carbonates found in the ocean basins, DCO members Adriana Dutkiewicz, Dietmar Müller, Sabin Zahirovic (all at the University of Sydney, Australia), and colleagues, developed a model of carbonate accumulation in deep-sea sediments spanning the last 120 million years. In a new paper in Geology, the researchers use the model to look at the impact of carbonate accumulation on global climate. The work provides a preliminary estimate of the size of the deep-sea sedimentary carbonate reservoir and its role in the deep carbon cycle over geological timescales. 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.
