Letter from the Director


The Deep Carbon Observatory mourns the loss of Louise Kellogg, who passed away on 15 April 2019 at age 59. A renowned geophysicist, Louise was principal investigator of DCO’s Modeling and Visualization Forum for Deep Carbon and a member of the DCO Executive Committee. The universe of science has lost a shining star, brilliant colleague, and dear friend. 

DCO’s Biology Meets Subduction team made a major contribution to our understanding of Earth’s deep carbon cycle. In an article published in Nature, they demonstrate that a forearc carbon sink sequesters a large fraction of the carbon released at convergent plate boundaries and reduces long-term volatile recycling into Earth’s mantle. Peter Barry, Maarten de Moor, Donato Giovannelli, and Karen Lloyd are among the paper’s 37 authors from 27 institutions in 7 countries. 

In a related development, DCO scientists Manuel Menzel and Carlos Garrido published two papers on the fate of carbon in subducting oceanic plates

Karen Smit and Steven Shirey of DCO’s Reservoirs and Fluxes Community are the lead authors of a paper in Science that proposes different mechanisms for the stabilization of continents based on mass-independently fractionated sulfur isotopes in diamonds. 

Another DCO paper on the isotopic composition of diamonds by Kan Li, Long Li, Graham Pearson, and Thomas Stachel indicates that altered igneous oceanic crust dominates deep carbon recycling

DCO’s Maria Luce Frezzotti is the lead editor of a thematic set of six papers on Carbon forms, paths, and processes in the Earth in the Journal of the Geological Society. These open access papers, which have more than a dozen DCO co-authors, are based on lectures at the Lake Como (Italy) School of Advanced Studies in 2017. 

Rajdeep Dasgupta is principal investigator of CLEVER Planets (Cycles of Life Essential Volatile Elements in Rocky Planets), which is dedicated to unraveling the conditions of planetary habitability in the Solar System and exoplanetary systems. CLEVER planets is supported by a $7.7 million NASA grant and involves fellow DCO researchers Laurence Yeung, Kyusei Tsuno, Damanveer Grewal, Tom McCollom, and Bernard Marty. Initial results include a series of papers on carbon and other volatile elements. 

A DCO news release has generated news stories in 16 countries and three languages about the Deep Energy Community’s research on abiotic methane.

We encourage you to nominate DCO colleagues for awards conferred by the Mineralogical Society of America (deadline 1 June 2019)—including the Roebling Medal, Dana Medal, MSA Award, Public Service Medal, and MSA Fellowship—and European Geosciences Union (deadline 15 June 2019). Please nominate deserving early career scientists for the DCO Emerging Leader Awards (deadline 1 July 2019).

Congratulations to Barbara Sherwood Lollar on her election as a Fellow of the Royal Society and to Ding Pan for receiving a Croucher Innovation Award

We look forward to sharing additional highlights as we approach the culmination of the initial DCO decadal program and develop plans to launch the next decade of deep carbon science.

Could Microbes be the Gatekeepers of Earth’s Deep Carbon? 
In 2017, an interdisciplinary group of early career scientists visited Costa Rica’s subduction zone, where the ocean floor sinks beneath the continent, to find out if subterranean microbes can affect geological processes that move carbon from Earth’s surface into the deep interior. According to their new study in Nature, the answer is yes. The study shows that microbes consume and trap a small but measurable amount of the carbon sinking into the trench off Costa Rica’s Pacific coast. The microbes may also be involved in chemical processes that pull out even more carbon, leaving cement-like veins of calcite in the crust. These unexpected findings have important implications for how much carbon moves from Earth’s surface into the interior, especially over geological timescales. The research is part of the Deep Carbon Observatory’s Biology Meets Subduction project and included DCO members Peter Barry (formerly at University of Oxford, UK, now at Woods Hole Oceanographic Institution, USA), Maarten de Moor (National University of Costa Rica), Donato Giovannelli (University of Naples Federico II, Italy), and Karen Lloyd (University of Tennessee Knoxville, USA), among many others.

Diamonds Reveal how Continents are Stabilized, Key to Earth’s Habitability
The longevity of Earth’s continents in the face of destructive tectonic activity is an essential geologic backdrop for the emergence of life on our planet. This stability depends on the underlying mantle attached to the landmasses. New research by DCO collaborators Steven Shirey, (Carnegie Institution for Science, USA), Erik Hauri (deceased, formerly of Carnegie Institution for Science, USA), and colleagues, published in the journal Science, demonstrates that diamonds can be used to reveal how a buoyant section of mantle beneath some of the continents became thick enough to provide long-term stability. About 150 to 200 kilometers, 93 to 124 miles, beneath the surface, geologic formations called mantle keels act as stabilizers for the continental crust. The material that comprises them must thicken, stabilize, and cool under the continent to form a strong, buoyant keel that is fundamental for preserving the surface landmass against the relentless destructive forces of Earth’s tectonic activity. But how this is accomplished has been a matter of debate in the scientific community. Read more...

Volcanic Rocks Will Do, When Studying Biggest Carbon Emitters
Volcanologists have made amazing progress in measuring the carbon dioxide escaping from volcanoes worldwide. But some volcanoes – including some that may be the biggest emitters of carbon dioxide – remain inaccessible due to geographical, political, or safety reasons. Without data from these volcanoes, it is difficult to make accurate global estimates of volcanic gas emissions. In a new paper in Scientific Reports, DCO researchers figured out a way to fill in those gaps in the data using rocks from hard-to-access volcanoes. Reservoirs and Fluxes Community members used trace element measurements from volcanic rocks, combined with sulfur dioxide emissions detected by satellites, and carbon emission data from similar volcanoes, to estimate the carbon released by remote volcanoes. Alessandro Aiuppa (Università di Palermo, Italy), Tobias Fischer (University of New Mexico, USA), Terry Plank (Columbia University, USA), and Philipson Bani (Université Blaise Pascal - CNRS -IRD, France) estimate that, all together, these previously “unmeasured” volcanoes release about 11.4 megatons of carbon each year.

Studies of Exhumed Seafloor Show Fate of Subducting Carbon
Ocean floor is born when lava wells out of underwater volcanoes along mid-ocean ridges. It slowly crawls across the globe due to the movement of other plates, picking up water and carbon-containing minerals through weathering along the way. Then it ends its life by plunging into the mantle beneath another tectonic plate through a process called subduction. We know that the subduction of ocean plates is a major sink of surface carbon because it transports carbon to the mantle where it stays over long timescales. Scientists, however, are still working on the finer details of how much of that accumulated carbon stays in the mantle, and how much dissolves or melts and washes up to the surface, where it gets stuck in the crust or escapes through nearby volcanoes. These are exactly the details that DCO scientists Manuel Menzel and Carlos Garrido (both from the Spanish Research Council and the University of Granada, Spain) are trying to figure out. In two new papers (published in the Journal of Metamorphic Geology and Lithos), they and their colleagues investigate what happens to the carbon in the subducting edge of an ocean plate, called the slab. Their findings can help researchers to improve their estimates of the fluxes of carbon moving in and out of the mantle in similar locations worldwide. Read more...

Eclogitic Diamonds Formed From Oceanic Crust, Study Shows
Diamonds are found in two types of rocks from Earth’s mantle: peridotite and eclogite. Peridotite is the most common type of mantle rock. Eclogite forms from igneous oceanic crust that together with a thin veneer of overlying marine sediment has been brought deep into the mantle through a process known as subduction. Many researchers thought eclogitic diamonds formed from the carbon contained in marine sediments, a large carbon reservoir. A new study, published in Earth and Planetary Science Letters, however, suggests the carbon in eclogitic diamonds originated as carbonates in the underlying ocean crust. The study involved DCO collaborators Long Li, Graham Pearson, and Thomas Stachel (all at the University of Alberta, Canada).

DCO Press Release: Rewriting the Textbook on Fossil Fuels
Experts say scientific understanding of deep hydrocarbons has been transformed, with new insights gained into the sources of energy that could have catalyzed and nurtured Earth’s earliest forms of life. During the past hundred years scientists worked out in detail how hydrocarbons — “fossil fuels” drawn from reservoirs in Earth’s crust to heat and power homes, vehicles, and industry — have a biotic origin, derived from the buried plants, animals, and algae of eons past. But for some hydrocarbons, especially methane — the colorless, odorless main ingredient in natural gas — it is now known that nature has many recipes, some of which are “abiotic” — derived not from the decay of prehistoric life, but created inorganically by geological and chemical processes deep within the Earth.

‘CLEVER Planets’ Project Aims to Discover How to Create Habitable Planets
The start of the deep carbon cycle on Earth was vital to creating a planet where life could evolve and thrive, but carbon doesn’t tell the whole story. The recycling, distribution, and storage of other bio-essential elements, including nitrogen, oxygen, sulfur, phosphorus, and hydrogen, also play a crucial role in making a planet habitable. With the formation of the CLEVER Planets (Cycles of Life Essential Volatile Elements in Rocky Planets) project, Rajdeep Dasgupta (Rice University, USA) is leading a multidisciplinary initiative to understand how these various chemical cycles function and interact to create a surface environment amenable to life on Earth and other rocky planets. In late 2018 Dasgupta received a five-year, $7.7 million grant from NASA’s Science Mission Directorate and also became part of their Nexus for Exoplanet System Science network, a collection of research groups studying the potential for life on planets outside our solar system. The initiative includes fellow DCO researchers Laurence Yeung, Kyusei Tsuno, Damanveer Grewal, (all at Rice University, USA), Tom McCollom (University of Colorado Boulder, USA), and Bernard Marty (Centre de Recherches Pétrographiques et Géochimiques, France).

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.

C-DEBI: Rolling Call for Research Exchange Proposals
The Center for Dark Energy Biosphere Investigations (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 $500-5,000 with additional matched funds to be granted annually.
