Panorama Mass Spectrometer on the Cover of the International Journal of Mass Spectrometry
When the Deep Carbon Observatory launched in 2009 it recognized the importance of investing early in new instrumentation vital to achieving its decadal goals. A key goal of the Deep Energy Community is to achieve a deeper understanding of methane formation temperatures and sources. DCO therefore co-sponsored the production of Panorama, the world’s largest gas-source multiple-collector mass spectrometer. Panorama was installed at the University of California Los Angeles (UCLA), USA, in March 2015. Since its installation, the instrument has been extensively tested, and already contributed to high profile publications. An in-depth article covering the many capabilities of the instrument appears in the 25 April 2016 edition of the International Journal of Mass Spectrometry, and is featured on the journal’s cover. DCO’s Edward Young (UCLA and DCO Deep Energy co-Chair) and Douglas Rumble (Carnegie Institution for Science, USA) co-authored the article with instrument builders Philip Freedman and Mark Mills (Nu Instruments, UK).

New Analyses of Komatiites Shed Light on Formation and Earth’s Hydrated Mantle
Earth’s mantle is complex and dynamic, driving processes at the surface and influencing myriad aspects of our everyday lives such as plate tectonics and volcanism. Over the course of Earth’s history, the mantle has changed, with slow cooling resulting in an evolving mineral composition. Understanding how Earth’s mantle changed following planetary accretion is challenging, and relies on finding ancient samples of erupted lava to study. Komatiites represent such ancient samples, and scientists have studied specimens from Canada, South Africa, and Australia for decades. In a new paper published in the journal Nature, a team of scientists including DCO collaborator Alexander Sobolev (Université Grenoble Alpes, France) performed new analyses on Canadian komatiite samples. Their work answers important questions about komatiite formation and the composition of Earth's mantle over deep time. Read more...
Pressure-dependent Iron Isotope Fractionation and Light Elements in Earth's Core
Earth formed from accreted matter surrounding the young Sun. Over time, the iron in this early planetary material moved inward, separating from the surrounding silicate. This process created the planet’s iron core and silicate upper mantle. But, due to the technological impossibility of taking samples from Earth’s core to see which compounds exist there, understanding how this differentiation process occurred is challenging. Seismic data show that in addition to iron, there are “lighter” elements present in the core, but which elements and in what concentrations they exist is a matter of great debate. This is because as the iron moved inward toward the core it interacted with various lighter elements to form different alloyed compounds, which were then carried along with iron into the planet’s depths. Which elements iron bonded with during this time would have been determined by the surrounding conditions, including pressure and temperature. New work from a team led by DCO’s Anat Shahar (Carnegie Institution for Science, USA) and including DCO Extreme Physics and Chemistry Community Co-Chair Wendy Mao (Stanford University, USA) uses this iron record to look at how Earth's core formed, and what light element(s) might be trapped there. The work is published in the journal Science. Read more...
Magmatic Gases in German Mineral Water Reveal the Origin of Volatile Elements on Earth
Earth formed approximately 4.54 billion years ago. Since that time, our planet has continuously evolved, experiencing numerous events in its history including formation of the core, differentiation of the mantle into separated reservoirs, production of oceanic and continental crust, recycling of crust into the mantle, late additions of volatile elements by comets and/or asteroids, and the escape of the early atmosphere. Because of these many modifications, the origins of Earth's volatile elements (hydrogen (water), carbon, nitrogen, and the noble gases) remain enigmatic, and it is difficult to determine if they originated from the solar gas that remained after solar-system formation (the solar nebula) or from differentiated bodies, such as asteroids, which may have collided with a young Earth. In a study published in Nature, a team of researchers including DCO's Bernard Marty (CNRS and Université de Lorraine, Nancy, France) report the results of high-precision noble gas analyses of a CO2-rich mineral spring gas located in the recent volcanic province of Eifel, Germany.

Novel Measurements of Carbon Degassing at Arc Volcanoes
Volcanoes are a constant, natural source of carbon to Earth’s atmosphere. However, scientists remain uncertain of just how much volcanic carbon, mostly in the form of carbon dioxide gas, is released over time. Directly measuring the gases constituting volcanic plumes is challenging, both technologically and physically. Recent technological advances, including higher instrument sensitivity and more portable instrument size, help scientists more easily detect volcanic CO2 signals above the atmosphere’s background, but volcanic peaks remain inhospitable, remote, and often dangerous places to work. In September 2015, several DCO scientists took part in a US NSF sponsored GeoPRISMS expedition to the Aleutian Islands onboard the R/V Maritime Maid. DCO DECADE (Deep Carbon Degassing) scientists Taryn Lopez (University of Alaska Fairbanks, USA) and Tobias Fischer (University of New Mexico, USA) focused their work on the Western Aleutian volcanoes, and in a new paper in Geophysical Research Letters they report the results of their airborne measurements of carbon chemical and isotopic composition emitted from Kanaga volcano.

DEEPER VIEW Enhancing Deep Carbon Science: Integrating Diverse Perspectives into Our Community
By Pat Leahy, Executive Director of the American Geosciences Institute, and Craig Schiffries, Director of the Deep Carbon Observatory
The Deep Carbon Observatory is collaborating with the American Geosciences Institute (AGI), a non-profit federation of over 50 geoscientific professional and scientific societies, in an effort to bolster the participation of geoscientists traditionally ethnically and racially underrepresented in the United States who are engaged in DCO research. According to the U.S. Office of Management and Budget, U.S. citizens and permanent residents who are considered underrepresented include African American, Native American, Native Alaskan, Hispanic, Latino, Latina, Native Hawaiian, and Native Pacific Islander. These groups continue to be engaged in geoscience well below their representation in the U.S. general population. AGI’s Workforce Program is spearheading this initiative, which has had continuous diversity development efforts since 1972 to ensure the geosciences are tapping the best and brightest talent across the U.S., regardless of race or ethnicity. This exciting new endeavor is designed to engage the unique perspectives and expertise of those groups of scientists to contribute to DCO’s global scientific enterprise. Read more...

Call for Proposals: Census of Deep Life Sequencing Opportunities
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, 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 bacterial 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 the DCO’s Deep Life Community. Deadline: 30 April 2016
DCO: Deep Life Cultivation Internship Program
The DCO Deep Life Community 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 deep subsurface. In order to maintain and strengthen cultivation strategies in future deep life missions, the Deep Life Community 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 Deep Life Community’s field missions. Financial support includes $5,400 per person for travel and lodging costs and host lab research supply reimbursement. Interested applicants should send their CV, a brief one page statement of their cultivation plans, and a letter of support from their intended host to Fumio Inagaki and Douglas Bartlett.
