Letter from the Director
DCO scientists are making important data-driven discoveries in disparate areas of research. Novel applications of network analysis to fossil data indicate that the evolution of early complex eukaryotes was affected by two biologic turnover events, perhaps the earliest mass extinctions of complex life, which helped shape the trajectory of early animal evolution. The research team—which includes paleontologists Drew Muscente and Andrew Knoll, data scientists Ahmed Eleish, Anirudh Prabhu, Feifei Pan, and Peter Fox, and DCO Executive Director Robert Hazen—is a triumph of the partnerships between DCO data scientists and specialists in other fields.
DCO Deep Life Community members Yinzhao Wang, Fengping Wang, Xiang Xiao, Gunter Wegener, and colleagues conducted a global survey of existing metagenomic data to find genes for a methane metabolism enzyme. They identified new and diverse groups of Archaea capable of producing or consuming methane, which suggests that methane metabolism evolved early in the evolution of Archaea.
Based on five years of high-frequency volcanic gas emission data, DCO Reservoirs and Fluxes Community members Maarten de Moor, Andrés Diaz, John Stix, Alessandro Aiuppa, Tobias Fischer, and colleagues observed patterns that provide precursors to violent eruptions.
In other DCO developments, the Carbon Mineral Challenge has now documented 28 new carbon minerals since the program’s launch in December 2015.
We are grateful to DCO early career scientists Simon Matthews and Lotta Purkamo, who served as co-chairs of the highly successful Geological Society of London’s (GSL) 2019 Janet Watson Meeting on “Atmosphere to Core: Deep Carbon.” This flagship meeting was part of GSL’s Year of Carbon.
The upcoming 2019 Goldschmidt Conference in Barcelona, Spain in August will feature numerous sessions that address deep carbon science. We encourage you to submit abstracts by the deadline on 29 March 2019. The deadline for session, town hall, and workshop proposals for the 2019 Fall Meeting of the American Geophysical Union (AGU) is also coming up, 17 April 2019. And please consider nominating a colleague for an AGU honor; the deadline for nominations has been extended until 15 April 2019.
And finally, congratulations to Donald DePaolo, who has been named the 2019 V.M. Goldschmidt Medalist, and Barbara Sherwood Lollar, who has been named the 2019 Clair C. Patterson Medalist by the Geochemical Society. Cin-Ty Lee, Shuguang Li, Barbara Sherwood Lollar, and Yuji Sano will become Fellows of the European Association of Geochemistry and the Geochemical Society.

Deep Life Not Limited to Microbes: Earthquakes Move Surface Animals to the Deep
In 2009, researchers discovered a tiny nematode living happily in the water inside rock fractures, more than a kilometer deep in a South African goldmine. They nicknamed the new creature the “devil worm” in honor of its dark, hot, deep home. Ever since the discovery of this and similar animals found more than three kilometers deep, they have wondered, how did these creatures get there? In a new paper in Scientific Reports, the researchers finally reveal the answer. By collecting water samples from boreholes in several South African mines and simulating the effects of earthquakes, the researchers propose that seismic activity forces surface water, and any organisms it contains, into deeper, rocky environments. While many of the imported organisms likely die off, some survive and reproduce. The findings suggest that areas with significant seismic activity may be good places to dig when looking for life on Mars because these sites may harbor life forms that once thrived on the surface. DCO members Gaetan Borgonie (Extreme Life Isyensya, Belgium), Cara Magnabosco (Flatiron Institute, USA), Borja Linage-Alvarez (University of the Free State, South Africa), Esta van Heerden (BioSaense Solutions, South Africa), Barbara Sherwood Lollar (University of Toronto, Canada), and Tullis Onstott (Princeton University, USA), collaborated on the project along with Scott Mundle (University of Windsor, Canada).

Remote Gas Monitoring Gives Warning Before Wet Eruptions
Poás volcano in Costa Rica is one of the most active volcanoes in Central America as well as a popular tourist destination. Inside its main crater sits a warm, hyperacidic lake saturated with sulfur. An underground hydrothermal system of water-filled conduits feeds the pond and also periodically releases impressive geyser-like jets of water. In mid-April, 2017, these occasional “phreatic” eruptions of water, steam, and other gases lead to “phreatomagmatic” eruptions that also included chunks of glowing rocks that damaged nearby structures. Historically, eruptions at “wet” volcanoes have been difficult to predict, but research at Poás is demonstrating that clear warning signals often exist in the gas emissions. In a new paper in Geophysical Research Letters, DCO researchers report that the gases emitted from Poás can give clues to interactions between water and melted rock, called magma, in the subsurface, and may signal an upcoming eruption. Reservoirs and Fluxes Community Members Maarten de Moor (Universidad Nacional, Costa Rica, and University of New Mexico, USA), Andrés Diaz (Universidad de Costa Rica), John Stix (McGill University, Canada), Alessandro Aiuppa, (Università di Palermo, Italy), Tobias Fischer (University of New Mexico, USA), and colleagues, tracked and analyzed the volcano’s emissions over five years.

Methane Metabolism in Archaea is Ancient and Widespread
In the oxygen-free parts of lakes, hot springs, and marine environments worldwide, some microbes generate a lot of methane as part of their daily metabolism, while others consume it for energy. Over geological timescales, the interplay of these activities likely had a big impact on Earth’s climate and the global carbon cycle. But despite the importance of methane metabolism, the identities of the microbial species involved is still poorly understood. DCO Deep Life Community members Yinzhao Wang, Fengping Wang, Xiang Xiao (all at Shanghai JiaoTong University, China), Gunter Wegener (Max Planck Institute for Marine Microbiology and MARUM, Germany), and colleagues expanded the number of groups of archaea believed to use or produce methane. By searching genomic data from environmental samples collected worldwide, the researchers identified a key gene needed for methane metabolism in unexpected and unrelated groups of archaea not known to use methane. The existence of the gene in diverse groups suggests that methane metabolism arose early in archaeal evolution and has long impacted Earth’s carbon cycle. They report their findings in a new paper in Nature Microbiology. Read more...
Early Extinctions Set the Stage for Life as We Know It
Many of the fossils left by the strange “Ediacara biota” that thrived during the Ediacaran Period (about 635 to 540 million years ago) look like ribbed pancakes, armored worms, and fat fern fronds. Despite finding these fossil deposits worldwide, paleontologists have struggled to place the unfamiliar creatures on the tree of life or even to agree on where and when they lived. Now, researchers are turning to data science tools to make sense of Ediacaran fossil data accumulated from decades of paleontological research. For the first time, researchers used a technique called network analysis, which reveals connections in complex systems, to analyze Ediacaran fossil collections and to match them to specific environments and times. The analysis provides evidence that two extinction events potentially linked to disturbances in the global carbon cycle occurred during this period. The extinctions created an opening for the subsequent Cambrian explosion, when most major groups of animals appeared for the first time in Earth’s history. Drew Muscente (formerly of Harvard University, now at University of Texas, Austin, USA), and Andrew Knoll (Harvard University, USA), with DCO researchers Ahmed Eleish, Anirudh Prabhu, Feifei Pan, Peter Fox (all at Rensselaer Polytechnic Institute, USA), and DCO Executive Director Robert Hazen (Carnegie Institution for Science, USA), report these findings in a new paper in Nature Communications.

Aquifer Microbes Survive on Hydrogen and Carbon Dioxide Diet
Based on what we know of early Earth and the origin of life, scientists think that the first cells lived in a warm environment fueled by water-rock reactions, such as a hydrothermal vent system, hot spring, or aquifer. The cells likely would have used hydrogen for energy and dissolved carbon dioxide for carbon to build their cells. Similar environments still exist on Earth today, and new research shows that the organisms that inhabit them probably make a living in the same way. In a new paper in The ISME Journal, DCO researchers report that microbes living on grains of the mineral olivine in a deep, subseafloor aquifer rely on an ancient type of metabolism called the Wood-Ljungdahl pathway, which uses hydrogen and carbon dioxide. Deep Life Community members Amy Smith (Woods Hole Oceanographic Institution, USA), Martin Fisk, Rick Colwell (both at Oregon State University, USA), Olivia Mason (Florida State University, USA), Radu Popa (University of Southern California, USA), and colleagues, sequenced the DNA from the community of microbes living on the grains and separated them into genomes representing 11 microbial species.

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.
