blue boron-bearing diamond
DCO researchers analyzed dozens of rare, expensive blue diamonds like this one to find the origin of these elusive gemstones. Mineral inclusions trapped inside the diamonds reveal that the gems have a deep and watery past. These diamonds formed in the lower mantle, from pieces of oceanic crust that sunk into the mantle through subduction. The work appears on the cover of the 2 August 2018 edition of Nature.

Letter from the Director


As the summer draws to a close, DCO scientists have unlocked mysteries about the origin of blue diamonds. In a paper featured on the cover of Nature (2 August 2018), Evan Smith (Gemological Institute of America, USA), Steve Shirey (Carnegie Institution for Science, USA), Fabrizio Nestola (University of Padua, Italy), and colleagues report that blue diamonds are among the deepest samples of Earth’s interior ever found and shed new light on deep-mantle recycling of surface materials. 

Another DCO research group demonstrated that crystalline polymeric carbon dioxide (CO2-V) is stable at lower-mantle conditions. Roberto Bini (Universita di Firenze, Italy), Kamil Dziubek and Demetrio Scelta (European Laboratory for Non-linear Spectroscopy, Italy), along with colleagues at the University of Vienna and the European Synchrotron Radiation Facility suggest that the presence of crystalline CO2 phases at lower-mantle conditions could represent a carbon source for chemical reactions and allow carbon transport to the core-mantle boundary.  

Michael Broadley (Centre de Recherches Pétrographiques et Géochimiques, France), and Peter Barry and Chris Ballentine (both at the University of Oxford, UK) suggest in a new paper in Nature Geoscience that the eruption of the Siberian flood basalts caused a massive halogen release to the atmosphere, which may have kicked off the largest mass extinction in Earth history. 

In a paper in the Proceedings of the National Academy of Sciences, Kelly Wrighton, Michael Wilkins (both at Colorado State University, USA), David Cole, Julie Sheets (both at The Ohio State University, USA), and colleagues present coupled laboratory and field investigations that explain how microbial communities persist in hydraulically fractured shale at the elevated temperature, pressure, and salinity found 2500 meters beneath Earth’s surface.

DCO researchers continue to be recognized for scientific excellence.  This month, Deep Life Community member Antje Boetius (Alfred Wegener Institute for Polar and Marine Research, Germany) was awarded the 2018 German Environmental Award for her “exemplary contributions to protecting the environment.”

We are seeking nominations for the 2018 DCO Emerging Leader Awards, which recognize early career scientists for distinguished performance and unique potential as leaders of the deep carbon science community. Please submit nominations by 28 September. It’s a great way to recognize the early career researchers who have made exceptional contributions to our community.

And last but not least, DCO released a new video on the Oman Drilling Project, featuring stunning footage of fieldwork in Oman as well as interviews with DCO scientists Peter Kelemen (Lamont-Doherty Earth Observatory, USA) and Alexis Templeton (NASA Astrobiology Institute, USA). Please don’t miss it!

Origin of Blue Diamonds Discovered
Experts judge a diamond’s worth by the four Cs, “color, clarity, cut, and carat weight,” and blue diamonds are no exception. These rare and expensive gemstones have a sparkling blue color and exceptional clarity. The largest ones measure more than 100 carats in their rough state. Scientists have puzzled over how these unusual diamonds form, and have finally come up with a fifth word that starts with “C” to describe their origins: crust. DCO researchers have found evidence that blue diamonds come from an exceptionally deep source, from the lower mantle, and that they form from materials that originated in the oceanic crust. Members of the Extreme Physics and Chemistry Community and the Reservoirs and Fluxes Community, Evan Smith (Gemological Institute of America, USA), Steve Shirey (Carnegie Institution of Washington, USA), Fabrizio Nestola (University of Padua, Italy), and colleagues, report these findings in a new paper in the journal Nature.

Amino Acid Metabolism Fuels Fracking Communities
Hydraulic fracturing, or “fracking,” has enabled natural gas companies to reach new heights in natural gas production. By pumping a mix of water and chemical additives into shale deposits, companies break up the rock to release more gas. This process opens up a subsurface habitat, seeding it with microbes carried along in the fracking fluid. A handful of organisms survive the high temperature, pressure, and salinity of their new home, 2,500 meters beneath the surface. In a new paper in the journal Proceedings of the National Academy of Sciences, a large collaboration including DCO members Kelly Wrighton, Michael Wilkins (both at Colorado State University, USA), David Cole, Julie Sheets (both at The Ohio State University, USA), Timothy Carr (West Virginia University, USA), and Paula Mouser (University of New Hampshire, USA), examines the community of microbes that persist in these environments, and tease apart the ways that they compete, cooperate, and prey on each other. Using techniques to catalogue all of the genomes and metabolites in methane well fluids, the researchers show that the community survives by fermenting amino acids and their derivatives, especially glycine betaine.

Carbon Dioxide Stays Solid Under Deep Mantle Conditions
On the surface, carbon dioxide moves in complex cycles between living organisms and the physical world. In the subsurface, carbon dioxide plays equally important roles, but tracking its movements through the crust and mantle is a much harder task. Theoretical models have predicted that carbon dioxide exists as a solid crystalline structure deep into the mantle, but high-temperature and high-pressure laboratory experiments have found that carbon dioxide dissociates to form oxygen and diamonds under these conditions. A new study from DCO Extreme Physics and Chemistry Community members Roberto Bini (Universita di Firenze, Italy), Kamil Dziubek and Demetrio Scelta (European Laboratory for Non-linear Spectroscopy, Italy), along with colleagues at the University of Vienna and the European Synchrotron Radiation Facility (ESRF), demonstrates that carbon dioxide can exist in a crystalline form under conditions simulating the core-mantle boundary. The researchers squeezed carbon dioxide up to 120 GPa (more than 1 million times greater than the pressure at sea level) and heated it to about 2400 degrees Celsius, which caused the carbon dioxide to rearrange into a tetrahedrally coordinated crystalline form called phase V. Their findings, published in a new paper in Nature Communications, suggest that carbon dioxide is more stable in the deep mantle than expected. Read more...

Did a Burst of Halogens Kick Off the End-Permian Extinction?
About 250 million years ago, one of the largest known volcanic events in history flooded the area that is now Siberia with lava, to create the Siberian flood basalts. A superheated mantle plume beneath the continent likely created the event, which erupted continuously for more than one million years. It led to the end-Permian mass extinction, wiping out more than 70 percent of all terrestrial species and 96 percent of all marine life. While scientists agree that the massive eruptions caused tremendous and rapid changes to the environment, there is ongoing debate about exactly why they were so destructive. DCO researchers propose that the erupted Siberian flood basalts released giant quantities of halogens, such as chlorine and bromine, into the atmosphere. These halogens may have eroded the ozone layer, allowing UV radiation from the sun to inundate Earth. Reservoirs and Fluxes Community member Michael Broadley (Centre de Recherches Pétrographiques et Géochimiques, France), and Deep Energy Community members Peter Barry and Chris Ballentine (both at the University of Oxford, UK), examined the halogen content of rock samples that surfaced in Siberia before and after the eruption of the flood basalts. Their results, reported in a new paper in the journal Nature Geoscience, suggest that massive halogen release to the atmosphere may have kicked off the largest mass extinction in Earth’s history.

VIDEO: Oman Drilling Project
In this video, DCO researchers Peter Kelemen (Lamont-Doherty Earth Observatory, USA) and Alexis Templeton (NASA Astrobiology Institute, USA) discuss how the secrets being revealed by this ancient seabed in Oman are helping to inform the search for life on other planets. The Oman Drilling Project is a collaborative multinational investigation of the Samail Ophiolite, the world’s largest, best-exposed, and most-studied subaerial block of oceanic crust and upper mantle. The Samail Ophiolite contains rock assemblages formed by seafloor spreading, providing scientists with an inside look at ancient oceanic lithosphere brought to the surface millions of years ago by tectonic plate action. The video, produced by CoLab Productions and the Engagement Team, with support from the Secretariat, was shot on location in the Sultanate of Oman over a period of 12 days.

A Behind-the-Scenes look at "The Most Unknown"
What happens when researchers from very different fields meet to discuss the questions that fuel their interest in science? A new movie called The Most Unknown is an experiment to find out. Director Ian Cheney, with funding from the Simons Foundation and Motherboard, sets up a chain of nine interviews between researchers from disparate disciplines. The film employs a unique setup where the first scientist visits the second’s home turf, and then the second scientist visits the third one, on and on, until the final scientist returns to visit the first. Instead of focusing on the details of their work, they discuss how they approach the big questions: What is consciousness? How did life begin? What is the nature of the universe? Remarkably, three of the featured scientists are affiliated with the DCO Deep Life Community. Geomicrobiologist Jennifer Macalady (Penn State University, USA), astrobiologist Luke McKay (Montana State University, USA), and geobiologist Victoria Orphan (California Institute of Technology, USA) all participated in the experiment. Macalady and McKay talked with DCO science writer Patricia Waldron over Skype about their experiences participating in The Most Unknown. Read more...

A Detailed Investigation of Inputs and Outputs at New Zealand’s Hikurangi Margin
In an ongoing US National Science Foundation-funded project, DCO researchers are investigating the flux of volatile compounds, like water, carbon dioxide and nitrogen gas, into and out of the mantle along the Hikurangi Margin, an active subduction zone off the east coast of New Zealand’s North Island. DCO researchers selected this area because it is a well-studied subduction zone where the oceanic plate, the Hikurangi Plateau, is sinking beneath the continental crust of the Indo-Australian Plate. The researchers are sampling key volatiles, including noble gases, and measuring inputs from the subducting oceanic plate and outputs from nearby volcanoes and hot springs. DCO Reservoirs and Fluxes Community member Gray Bebout (Lehigh University, USA) and a founding member of the DECADE project, Bruce Christenson (GNS Science, New Zealand) are collaborating with Hirochika Sumino (University of Tokyo, Japan) and Ikuko Wada (University of Minnesota, USA), along with Lehigh University Ph.D. student Gabe Epstein. The group plans to use thermal and thermodynamic modeling to map the movement of volatiles out of the subducting slab, investigating major factors affecting this recycling process. The work will yield more accurate estimates of the volatiles moving in and out of the subsurface at subduction zones. 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.
