Letter from the Director
“Food for microbes abundant on Enceladus,” according to a news article by Paul Voosen in Science. The news article is based on a Science paper co-authored by DCO Deep Energy Community member Chris Glein (Southwest Research Institute, USA), “Cassini finds molecular hydrogen in the Enceladus plume: Evidence for hydrothermal processes.” The discovery of molecular hydrogen escaping from Saturn’s moon Enceladus, which has a layer of ice covering a subsurface ocean, indicates that water is reacting with rocks on the floor of the alien ocean. The process might resemble hydrothermal vents on Earth’s seafloor. An accompanying commentary by DCO Deep Energy Community member Jeffrey Seewald (Woods Hole Oceanographic Institute, USA) says, “Chemical disequilibrium that is known to support microbial life in Earth’s deep oceans is also available to support life in the Enceladus ocean.” Voosen takes this reasoning further, “Because such chemistry provides energy for microbial life on Earth, the discovery makes Enceladus the top candidate for hosting life elsewhere in the solar system—besting even Jupiter’s Europa, another icy moon with an ocean.”
Returning to Earth, Megan Duncan and Rajdeep Dasgupta (Rice University, USA) published a paper in Nature Geoscience linking the rise of atmospheric oxygen to the deep carbon cycle. Based on high pressure-temperature experiments, they contend that the Great Oxidation Event, which occurred 2.5 to 2.2 billion years ago, is causally linked to the mobilization of organic carbon in subduction zones and deep sequestration of reduced carbon in the mantle. According to Duncan, “The study indicates that the rise in oxygen levels and the ability of the atmosphere to support life as we know it is strongly tied to the plate tectonic cycle.” It demonstrates connections between the deep carbon cycle and the conditions for life at or near the surface of a planet. These are but two examples of how DCO scientists are unraveling the mysteries of life on Earth and other planets.

Hydrogen Gas Detected in Plume on Saturn’s Moon Enceladus
For almost 20 years, NASA’s Cassini spacecraft has traveled through space, sending back photos and valuable information from Saturn and two of its potentially habitable moons, Enceladus and Titan. On 15 September 2017, the craft will take its final loop, and then dive through Saturn’s atmosphere, burning up in the process. A new study of data collected from Cassini’s flybys of the ice-covered moon Enceladus shows the presence of molecular hydrogen, likely emanating from hydrothermal vents in the ocean beneath the ice. The abundance of hydrogen creates a chemical disequilibrium that, on Earth, supports microbial life. DCO Deep Energy Community member Christopher Glein (Southwest Research Institute, USA) and colleagues describe their new findings in a recent paper in the journal Science. Read more...
Nickel May be Magic Ingredient in Planetary Core Formation
Knowledge of the composition of Earth’s core and the cores of other planetary bodies offers clues to how the solar system formed and to Earth’s early history. Scientists believe that Earth’s core is a dense ball of iron, nickel, and other lighter elements, but the identity and proportions of those elements are still up for debate. While investigating lighter element candidates, DCO Extreme Physics and Chemistry Community member Anat Shahar and postdoctoral associate Stephen Elardo (both of the Carnegie Institution for Science, USA) made an interesting discovery about the role of nickel in the formation of cores in planetary bodies. Through high-temperature and pressure experiments simulating core formation, the researchers found that nickel can affect how iron isotopes separate into the mantle and core. Adding more nickel causes heavy iron isotopes, which are iron atoms with extra neutrons, to enter the planet’s metal core, while lighter iron atoms stay in the surrounding mantle. This discovery may offer an explanation for the varying iron isotope signatures found on Earth, the Moon, Mars, and the asteroid Vesta. Shahar and Elardo describe their findings in a new paper in the journal Nature Geoscience. Read more...
Study Finds Core Formation Not Responsible for Earth’s Iron Anomaly
Compared to other bodies in the solar system, Earth has an unusual iron isotope profile, with a large percentage of heavy iron atoms occurring in the mantle. Scientists have conceived of several explanations for this anomaly, such as the high-pressure, high-temperature conditions that formed Earth’s core; the ancient collision with another body that created the Moon; or the melting occurring within the mantle to generate new crust. Now, new research casts doubt on core formation as one of the possible explanations. A group led by DCO Extreme Physics and Chemistry Community Member Jung-Fu Lin (University of Texas at Austin, USA) subjected mantle and core materials under high pressure to simulate planetary formation. They found that the process had little effect on how iron isotopes separate into different layers, suggesting core formation cannot explain Earth’s isotope profile. The researchers describe their findings in a new paper in Nature Communications. Read more...
Deep Burial of Organic Carbon into the Mantle Enabled “Great Oxidation Event”
The “Great Oxidation Event” (GOE) occurred about 2.5–2.2 billion years ago, when oxygen levels in the atmosphere began to rise up to 10,000 times, reaching up to 1% of the present level. The rise across the GOE and the subsequent increases in Earth’s atmospheric oxygen enabled the emergence of multicellular organisms, finally leading to plants, dinosaurs, and primates. A combination of factors led to the GOE, including the actions of oxygen-producing cyanobacteria in the oceans and the burial of dead organic matter. A new paper by DCO Extreme Physics and Chemistry and Reservoirs and Fluxes Community member Rajdeep Dasgupta (Rice University, USA) and Megan Duncan (now at the Carnegie Institution for Science, USA) proposes that subduction, the descent of tectonic plates into the mantle, was a key process in the efficient, long-term storage of reduced carbon, making the GOE possible. Using high-temperature and high-pressure experiments combined with thermodynamic models, the researchers looked back in time to model how carbon ‘burial’ would impact atmospheric oxygen levels. They describe their findings in a new paper in the journal Nature Geoscience. Read more...
New LIDAR Instrument Lets Volcanologists Monitor Eruptions from Afar
Recent studies suggest that before a volcano erupts, it ramps up its release of carbon dioxide from magma deep below the surface. These fluxes may provide an important early warning signal that an eruption is imminent. Researchers can measure volcanic gases using sampling instruments, but they must install these devices at the rim of the crater, placing both themselves and the instrument at risk. Alessandro Aiuppa, along with fellow Reservoirs and Fluxes Community members Roberto D’Aleo (both of the Università di Palermo, Italy), Marco Liuzzo and Gaetano Giudice (both of the Istituto Nazionale di Geofisica e Vulcanologia, Italy), and colleagues from ENEA (Agenzia Nazionale per le nuove tecnologie, l’energia e lo sviluppo economico sostenibile), have developed a new generation of instruments to measure volcanic gases remotely. They successfully used a type of laser scanning technology called LIDAR to measure carbon flux at Stromboli volcano, described in a paper in Frontiers in Earth Science, and at Mt. Etna, published in a study in the journal Geosciences. The work receives funding from the ERC (European Research Council) BRIDGE project and is in collaboration with DECADE (Deep Earth Carbon Degassing), a DCO initiative to estimate the global release of volcanic carbon by monitoring some of Earth’s most active volcanoes.

“Nesting Doll” Minerals Offer Clues to Earth’s Mantle Dynamics
Recovered minerals originating in the deep mantle offer scientists a rare glimpse of the dynamic processes occurring deep inside Earth. These minerals are also a window into the past, capturing snapshots of the history of the planet’s mantle layer. A team led by DCO member and experimental petrologist Yingwei Fei (Carnegie Institution for Science, USA) and field geologist Cheng Xu (Peking University, China) found that a rare sample of the garnet mineral majorite, discovered in North China, formed at least 370km (235 miles) below Earth’s surface. Fellow DCO member and Peking University colleague Renbiao Tao also contributed to the study. They published their findings in Science Advances. Read more...
Model of Australia’s Tectonic Stress May Future-Proof Carbon Storage
In response to ever-rising carbon dioxide levels in the atmosphere, some countries are exploring carbon sequestration as a way to mitigate the effects of this greenhouse gas. The general strategy is to inject carbon dioxide more than a mile underground, beneath an impermeable rock layer, where it can dissolve into fluids and crystallize. Injection locations must be chosen carefully, however, as small quakes and shifting fault lines could lead to burps and leaks, causing future climate issues. DCO modeling expert Dietmar Müller (University of Sydney, Australia), worked with colleague Scott Dyksterhuis (ExxonMobil, USA) to predict changes in the Australian crust 1 million years in the future. They modeled the geologic forces pushing and pulling the Australian continent to create a future stress field, which maps out the direction and intensity of tectonic stress applied at locations across the country. The researchers describe their methods in a new paper in the journal Fuel, which they hope will be useful in evaluating potential carbon sequestration sites and reducing the chance of future leaks. Their plate tectonic models also have applications for studies of subduction and deep carbon cycling through geologic time. Read more...
VIDEO: Drones Help Scientists Study Guatemalan Volcanoes
A new video from DCO’s Emma Liu (University of Cambridge, UK) and colleagues shows breathtaking aerial footage of the very active Volcán de Fuego in Guatemala. Liu and her colleagues used three different kinds of unmanned aerial vehicles, or drones, to get up close and personal with Volcán de Fuego during an eruptive period in February 2017. Following these successful pilot measurements, the team will return to Volcán de Fuego later this year to fly fully-instrumented vehicles up to the volcano. The video is the result of a collaboration between aerospace engineers at the University of Bristol, UK and volcanologists at the Universities of Cambridge and Bristol, UK and the Università degli Studi di Palermo, Italy.

New Exhibit Opens in Vienna, Showcases Mineral Evolution on Earth
The next time you head to the rock or gems exhibit at a museum, you may be surprised at what you find. Through the work of DCO’s Executive Director, Robert Hazen (Carnegie Institution for Science, USA), a revolution in museum exhibits is underway to recognize the important, changing roles of minerals through Earth’s long history. “There’s a growing awareness of the dramatic changes in Earth’s mineralogy over the past 4.5 billion years. Remarkably, that epic “mineral evolution” story is as much about life as it is about rock. We now realize that minerals and life co-evolved,” says Hazen. This revolution of mineral exhibits was launched with the opening of a permanent new mineral display at the Natural History Museum of Vienna on 4 April 2017. The opening was feted with a news conference and public lecture where Hazen shared his view of mineral evolution to a packed house. Read more...

Census of Deep Life Sequencing Opportunities: Request for Proposals
Since 2011, the Deep Carbon Observatory’s Deep Life Community has sponsored the Census of Deep Life (CoDL) that has supported surveys of the diversity of microbes present in several deep continental and subseafloor environments. The first surveys (2011-2012) were conducted using 454 pyrosequencing and subsequently (2013) Illumina sequencing strategies were adopted. Through this initiative, the Deep Life Community has allowed the characterization of diversity of subsurface microbial communities at numerous sites worldwide, including the subseafloor and deep continental locations from a range of geologic settings (e.g., large igneous provinces, subglacial lakes, methane hydrate-rich sediments, and cratons). The Illumina platform provides increased numbers of reads for more samples at reduced cost. For DNA samples submitted to the CoDL for sequencing, proponents have the option of obtaining 400-450 nt sequences that span the V4V5 region of Bacterial and Archaeal rRNA coding regions or a greater number of reads for V6 regions that through complete overlap of forward and reverse reads allows detection of lower abundance taxa with reduced stochastic error rates. Shotgun metagenomic DNA sequencing for key samples can also be performed. This call for proposals aims to support sequencing that represents expanded analyses from ongoing Deep Life Community projects or projects that represent sites and investigators new to DCO’s Deep Life Community. Proposal deadline: 30 April 2017
C-DEBI: Rolling call for Research Exchange proposals
C-DEBI facilitates scientific coordination and collaborations by supporting student, postdoctoral, and faculty exchanges to build, educate, and train the deep subseafloor biosphere community. We award small research exchange grants for Center participants. These grants may be used to support research, travel for presenting C-DEBI research at meetings, or travel exchanges to other partner institutions or institutions that have new tools and techniques that can be applied to C-DEBI research. We anticipate ~10 awards of $500-5000 with additional matched funds to be granted annually.
