Letter from the Director

DCO continues to report discoveries across the entire breadth of deep carbon science. In a paper published in Science, DCO members Daniel Frost, Catherine McCammon, and colleagues provide evidence that a “carbon pump” and “diamond factory” would operate in a deep magma ocean during Earth’s early history. This carbon pump might have been important for moving CO2 from the atmosphere into the mantle, explaining Earth’s carbon-rich interior and influencing the composition of its atmosphere. 

In another contribution from DCO’s Extreme Physics and Chemistry Community, Ding Pan and his graduate student Nore Stolte conducted ab initio molecular dynamics simulations of aqueous fluids at pressure and temperature conditions similar to those in Earth’s upper mantle and determined that carbonic acid is an important carbon carrier in the deep carbon cycle

Anaïs Cario, Gina Oliver, and Karyn Rogers describe the Pressurized Underwater Sampler Handler (PUSH50), a DCO instrumentation initiative designed to maintain in situ pressure while sampling and cultivating subsurface microorganisms. By avoiding decompression entirely, these and other researchers hope to refine our understanding of deep life and its contributions to global biogeochemical cycles.

In other research on deep life, Avishek Dutta, Pinaki Sar, Himadri Bose, Douglas Bartlett, and colleagues explored archaeal communities in the deep terrestrial subsurface underneath the Deccan Traps, India and the genomic basis of pressure tolerance of a microbial community within the Deccan traps.

DCO members Gustavo Ramírez, Beth Orcutt, and colleagues investigated the ecology of subseafloor crustal biofilms by conducting experiments at subseafloor observatories in the Eastern Pacific Ocean. They determined that biofilm community structure is driven by temperature rather than mineralogy, and that rare planktonic lineages colonize the crustal biofilms.

DCO scientists Kate Laxton, Emma Liu, and colleagues deployed novel technologies to sample lava and measure carbon dioxide emissions during a recent field expedition to Ol Doinyo Lengai in Tanzania, the world’s only natrocarbonitite volcano, which is renowned for its low viscosity, carbon-rich lava. 

As part of DCO’s plans to launch the next decade of deep carbon science, we are facilitating sessions on deep carbon science at conferences in 2020. The JpGU-AGU Joint Meeting 2020 session proposal deadline is 11 October 2019. The Goldschmidt 2020 session and workshop proposal deadline is 18 October 2019. The nomination deadline for 2020 Geochemistry Fellows of the Geochemical Society and European Association of Geochemistry is 31 October 2019. Please continue organizing deep carbon science sessions at conferences and nominating your DCO colleagues for awards in 2020 and beyond. 

Congratulations to Sergey Lobanov, Cara Magnabosco, Shaunna Morrison, and Ding Pan for receiving the 2019 DCO Emerging Leader Awards. Fittingly, the DCO Emerging Leader Awards will be presented at Deep Carbon 2019: Launching the Next Generation of Deep Carbon Science

The Early Magma Ocean Turned Earth into a ‘Diamond Factory’
Many questions remain about Earth’s formation around 4.6 billion years ago. Why does Earth store so much carbon in the mantle, but not other elements, like hydrogen and nitrogen? How did the first oxidized compounds necessary for life, like carbon dioxide and water, leak from Earth’s interior to accumulate at the surface? Now a new study may explain both these mysteries. DCO scientists Daniel Frost, Catherine McCammon (both at University of Bayreuth, Germany), and colleagues replicated the “magma ocean” stage of Earth’s evolution that occurred when a giant impact blasted off enough rock to create the Moon and melted the rocky planet. They discovered that under high-pressure and temperature conditions deep in the molten magma ocean, iron likely displayed some surprising chemical behavior. Its unusual activity may have helped to oxidize the surface and create a “carbon pump” that moved carbon dioxide into the mantle where it formed diamonds. This behavior may be one reason why Earth supports life, while its neighbor Venus, which never experienced a magma ocean phase, suffocates inside a thick, carbon dioxide rich atmosphere. The novel findings are published in a new paper in Science. Read more...

Subseafloor Biofilms Grow with the Flow
The crust beneath the seafloor is a vast but remote habitat, peppered with poorly studied microbes in its deep, dark crevices. Scientists have tapped into subsurface aquifers to study the organisms living in the fluids, but determining what kinds of microbes cling to the rocks is a much more challenging endeavor. Ocean drilling expeditions bring up rock cores full of microbes, but these samples tend to be contaminated with drilling fluids. To sample the biofilms living within the rocks, researchers decided to go fishing for them, using different rock types as bait. In a new paper in Frontiers in Microbiology, Deep Life Community Members Gustavo Ramírez (University of Rhode Island, USA), Beth Orcutt (Bigelow Laboratory for Ocean Sciences, USA), and colleagues analyzed the biofilms that grew on rocks placed in the path of subsurface water flow. They discovered that the attached communities were sourced from rare free-swimming microbes in the same environment, and that temperature played a large role in determining which microbes colonized the rocks. Read more...

Microbes in Deccan Traps Go to Extremes
About 65 million years ago, massive volcanic eruptions spread lava over an estimated 1.5 million square kilometers in India creating the Deccan Traps. In the millions of years since, the Traps have eroded into impressive layered rock formations and microbes have colonized their fissures and fluids. Only recently have scientists been able to access these microbes through scientific drilling expeditions and figure out how they survive within these deep, nutrient-limited rocks. In two new publications, DCO Deep Life Community members Avishek Dutta, Pinaki Sar, Himadri Bose (all at Indian Institute of Technology Kharagpur, India), Douglas Bartlett (University of California San Diego, USA), and colleagues further illuminate these deep communities. The researchers explored the archaea living within the Deccan Traps basalt and the underlying 2.5 billion-year-old granite basement layer. They also investigated how these “extremophiles,” which are microbes that survive in seemingly inhospitable environments, survive the heat and intense pressure of the Deccan Traps. Despite the challenging conditions, microbes persist in this environment and actively contribute to deep biogeochemical cycles. Read more...

Carbon Dioxide in Deep Waters: Sparkling Water or Acid?
When studying the deep carbon cycle, scientists can’t afford to discount the actions of water, which is an important vehicle moving carbon between the surface and subsurface. But what form does carbon dioxide take when dissolved in water? At the surface, this mixture is just sparkling water, but recent research has shown that these compounds behave very differently under the high temperatures and pressures found in the mantle. A new paper by DCO Extreme Physics and Chemistry Community member Ding Pan (The Hong Kong University of Science and Technology, China) and his graduate student Nore Stolte, suggests that carbon dioxide turns into carbonic acid under upper mantle conditions. The researchers used complex computer simulations to predict how the molecules would behave under a range of elevated pressures and temperatures. If large amounts of carbonic acid exist in watery mantle fluids, that could impact the pH of the upper mantle and how fluids dissolve minerals in deep Earth. The researchers report their findings in The Journal of Physical Chemistry Letters. Read more...

The PUSH for High-Pressure Microbiology
Microbes in the deep biosphere exist at pressures that would crush most surface organisms.  At one kilometer beneath the ocean’s surface, for example, a person would experience about 100 times the pressure at sea level, which is equivalent to a cow standing on every square inch of the body. And even deeper into the ocean, and the underlying seafloor sediments, and ocean crust, the pressure only continues to grow. These seemingly extreme pressures are part of everyday life for deep microbes. To obtain a complete picture of what’s going on in the subsurface, scientists need to study microbes under these native pressure conditions. In a new paper in Frontiers in Earth Science, DCO Deep Life Community members Anaïs Cario, Gina Oliver, and Karyn Rogers (all at Rensselaer Polytechnic Institute, USA) discuss the challenges of sampling and culturing microbes under constant high pressure, and also highlight recent technological advances. They describe the Pressurized Underwater Sampler Handler (PUSH50), supported by the DCO, which is designed to maintain in situ pressure during sampling and throughout the transfer and culturing process in the lab. By applying this technology to conduct experiments that avoid decompression entirely, the researchers hope to refine our understanding of deep life and its contributions to global biogeochemical cycles.

Field Report: Ol Doinyo Lengai Volcano, Tanzania
In 2007, Ol Doinyo Lengai volcano in Tanzania erupted explosively, creating a deep crater. Previously, the crater had been filled to overflowing with lava and scientists could walk up and collect a sample with a spoon. A year after the eruption, lava again began to bubble up at the base of the 100-meter-deep crater, but it appeared far out of the reach of scientists. Rather than waiting for the crater to refill, Reservoirs and Fluxes Community members Kate Laxton (University College London, UK), Emma Liu (University of Cambridge, UK), and colleagues undertook an ingenious and highly successful sampling trip involving rock climbing equipment, cocktail shakers, and hamster balls. They spent eight days and nine nights atop the volcano’s windy summit in late July and early August, working with researchers at the Geological Survey of Tanzania and Dar es Salaam University. By analyzing the composition of the first lava samples collected since the volcano’s eruption, they hope to learn about any recent changes to its underground plumbing system. The researchers also took up-to-date measurements of carbon dioxide emissions to inform more accurate climate models. 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.
