T-Limit of the Deep Biosphere off Muroto: IODP Expedition 370
One of the key scientific objectives in studies of deep life and carbon is to understand environmental factors that constrain population, activity, diversity, and ecological function of microbial communities, and the extent of habitable zones in Earth's interior. To better constrain the temperature limit of life in the deep biosphere, the International Ocean Discovery Program (IODP) is preparing Expedition 370 "T-Limit of the Deep Biosphere off Muroto (T-Limit)" with the Japanese drilling vessel Chikyu to revisit Ocean Drilling Program (ODP) Site 1174 in the Nankai Trough subduction zone off Cape Muroto, Japan. The expedition is scheduled for 10 September - 10 November 2016. Interested scientists are invited to attend a project workshop onboard Chikyu (25 June 2016). Read more...

Advancing Instrumentation to Study Materials and Reaction in Earth’s Deep Interior
In pioneering work performed at the Geophysical Laboratory Carnegie Institution for Science, USA, Alexander Goncharov and his colleagues developed a variety of optical spectroscopy tools that enable accurate measurements at extreme conditions of high pressure and high temperature.

Linking DCO’s Communities with Integrated Modeling: New Proposal Funded
Despite the importance of carbon transport by melts and fluids in deep Earth, there is currently no integrated model of chemical communication between the two. In a new proposal funded by the Alfred P. Sloan Foundation, Mark Ghiorso (OFM Research, USA) and Dimitri Sverjensky (Johns Hopkins University, USA) aim to address this key scientific problem. The proposed work will integrate existing thermodynamic models of magmas (MELTS) and fluids (Deep Earth Water, DEW) and form a framework for modeling mass transfer and transport of carbon and other chemical elements. This work will involve partial reformulation and recalibration of the two models so they can be made interoperable. It will also extend the models to span a continuum of liquid compositions between aqueous solutions and silicate liquids, yielding the first integrated thermodynamic model of the magma-fluid system.

Microbial Diversity Varies with Depth in Fennoscandian Precambrian Bedrock
The deep microbial biosphere inhabits varied ecological niches. From marine sediments to hydrothermal systems and fissures in continental bedrock, Bacteria and Archaea, and some particularly hardy Eukarya, thrive in complex and often interdependent ecosystems. The combination of advances in DNA sequencing technologies and sampling in numerous locales around the world is changing our understanding of the deep biosphere. A dramatically enhanced appreciation for diversity goes hand in hand with a realization of common keystone species in subsurface niches. In a new study from DCO Deep Life and Deep Energy scientists, Lotta Purkamo (VTT Technical Research Center, Finland) and colleagues investigate the microbes living in the Outokumpu deep borehole in Finland. The borehole extends over 2km into the Fennoscandian Precambrian shield, with fractures into the rock along the length of the hole allowing the team to assess microbial diversity as a function of depth.

The Trail by Fire Expedition Comes to an End
From October 2015 to February 2016 the Trail by Fire expedition surveyed the length of the Nazca plate subduction zone making gas measurements at 15 active volcanoes from Peru to southern Chile. With nearly 200 active volcanoes (4 currently erupting and 18 in a state of unrest), the South American Andes is one of the world’s most tectonically and volcanically active regions. The remote locations, high elevations (up to 6893 m), and lack of established trails to the summit of most of these volcanoes resulting in this entire region being almost absent from the global database of volcanic gas emissions. The objective for Trail by Fire was to correct this and take a snapshot of volcanic emissions at the scale of an entire volcanic Arc. In this article, the team summarizes their time in the field.

Deep Carbon Science in Wikipedia
Wikipedia, the free crowd-sourced online encyclopedia, is one of the top ten websites in the world in terms of its monthly traffic. Over five million Wikipedia articles cover a vast range of topics, dozens of which relate to topics of interest to DCO, from bioreactor to kimberlite to x-ray diffraction. For DCO, Wikipedia offers an opportunity to present deep carbon science to a broader audience. DCO research will develop new knowledge, as well as refine and expand our understanding of existing topics. Presenting the advances in deep carbon science to an audience numbering in the millions will be an important part of DCO's legacy. For all of these reasons, the Engagement Team is spearheading the effort to include DCO science in relevant Wikipedia entries. To this end, we are soliciting recommendations for article topics. In some cases, DCO researchers will be able to improve or expand upon existing articles by providing expert review. In other cases, DCO researchers may want to provide entirely new content. The Engagement Team will facilitate this process by updating the articles with DCO scientists' edits. While we encourage everyone in the DCO Science Network to review and edit Wikipedia content directly, we are available to assist, answer questions, or make the edits on your behalf. Read more...

The DCO Engagement Team is seeking feedback on ways we can improve the DCO website. Please take 5 minutes and fill out this short survey by 30 June 2016.

Funding Opportunities

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: 15 July 2016

Second Call for Proposals: Deep Energy Community 
The Deep Energy Community (DEC) of the Deep Carbon Observatory invites proposals for short- term funding of projects and/or activities aimed at addressing the DEC’s decadal goals and/or strengthening the international DEC community and its abilities to generate funding for new and ongoing initiatives. The DEC has identified a number of guiding questions and the DEC Steering Committee encourages submission of ideas for modest short-term support that will address these and other relevant/meritorious efforts with high potential to attract new funding. Examples of supported activities include 1) laboratory research, 2) travel to field sites to collect samples of key importance, 3) working groups and workshops to synthesize data for publication of Deep Energy research, and/or to develop interdisciplinary collaborations, 4) travel to work with collaborators on the preparation of new proposals, or 5) other activities that would advance Deep Energy Goals. More information is available here. Deadline: 20 July 2016

US NSF GeoPRISMS Program Solicitation
The GeoPRISMS (Geodynamic Processes at Rifting and Subducting Margins) Program investigates the coupled geodynamics, Earth surface processes, and climate interactions that build and modify continental margins over a wide range of timescales. These interactions cross the shoreline and have applications to margin evolution and dynamics, construction of stratigraphic architecture, accumulation of economic resources, and associated geologic hazards and environmental management. The GeoPRISMS Program includes two broadly integrated science initiatives (Subduction Cycles and Deformation and Rift Initiation and Evolution), linked by five overarching scientific topics and themes, where transformative advances are likely to occur in the decade 2011-2020, and where a focused scientific program could be most effective. These overarching science topics include 1) Origin and evolution of continental crust; 2) Fluids, magmas and their interactions; 3) Climate-surface-tectonics feedbacks; 4) Geochemical cycles; and 5) Plate boundary deformation and geodynamics. Each of the initiatives has identified primary sites for focused investigations, as well as thematic studies that will complement primary site studies. Deadline: 26 July 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.

PhD Studentship: Chemolithotrophs on Mars: Metabolic pathways and Biosignatures at the University of St Andrews, UK
A fully-funded 42 month PhD Studentship is available within the Planetary Habitability group at the University of St Andrews, supervised by Claire Cousins and Aubrey Zerkle. Please note this project is open to UK and EU nationals only. Whether Mars once supported life is a core aspect of space exploration. A major step in this endeavour is unravelling how life can be geochemically sustained and recorded in Martian environments. This project will use microorganisms from ice-fed hydrothermal lakes and pools in Iceland to elucidate which chemolithotrophic metabolisms dominate Mars-like habitats, and identify their resulting biosignatures that will eventually become part of the geologic record. Just as terrestrial geological processes can be used as analogues for their Martian counterparts, terrestrial biology can serve as a proxy for putative Martian biota. Mars-like environments exist at the Kverkfjöll volcano in Iceland. Chemolithotrophic microbial communities will be enriched from hydrothermal samples under both standard laboratory and simulated Martian conditions. Microbial community genomics, active metabolic pathways, and resulting sedimentary organic products and carbon, nitrogen and sulfur stable isotope biosignatures will be investigated to answer the following: Which chemolithotrophic metabolisms dominate Mars analogue habitats? What organic and inorganic biosignatures are produced by these communities? How do chemolithotrophs and their biosignatures change under Mars-like conditions? General information about eligibility, studying at the University of St Andrews, and the online application form are here. For specific questions about the project please email Claire Cousins. Application deadline: 30 June 2016
