We are exploring the frontier of the "deep biosphere" – microbial life in the rocks and sediments below the ocean floor that makes up 70% of our planet’s surface.

This previously unknown Bacillus living 342 meters below the ocean floor is one of very few isolated from the subseafloor crust.

Studying these organisms will reveal important, novel, and basic insights into the unique metabolic features of microbes in the deep biosphere.

About 0.6% of the Earth’s total living biomass is in subseafloor sediments. This finding updates previous estimates made in 1998.
Global Implications

We require specialized technologies to collect and analyze samples from the deep biosphere, including sensors, samplers, and platforms, deep-sea submersibles, scientific drilling research ships, and ROVs (remotely operated vehicles).

Announcements

C-DEBI Renewed for Phase Two!

I have exciting news to report. C-DEBI has just been renewed by the National Science Foundation for another five years! Phase One started in 2010 with the exploration of the deep subseafloor biosphere, especially at three sites — the South Pacific Gyre, the Juan de Fuca Ridge flank, and ‘North Pond’ in the North Atlantic. In Phase Two our research, education, and outreach activities will combine further field exploration with laboratory experiments and modeling. Thank you all for your continued interest in and support of this Center. And keep checking our website and reading our newsletter about ways to get or stay involved with C-DEBI.

C-DEBI Contribution 264 in Nature Communications

Vast quantities of ocean water circulate through the seafloor, flowing through the volcanic rock of the upper oceanic crust. A new study by scientists at UC Santa Cruz (including C-DEBI Co-I Andrew Fisher), published in Nature Communications, explains what drives this global process and how the flow is sustained.

For the new study, first authorand C-DEBI Graduate Fellow Dustin Winslow, a UCSC Ph.D. candidate who graduated this month, developed the first three-dimensional computer models showing how the process works. The models reveal a 'hydrothermal siphon' driven by heat loss from deep in the Earth and the flow of cold seawater down into the crust and of warmed water up out of the crust.

Collaborative development of C-DEBI resources for community colleges (Peter Tuddenham, Tina Bishop (The College of Exploration), Lynn Whitley (University of Southern California), Pat Harcourt)
To address the educational objectives of C-DEBI the College of Exploration was funded by C-DEBI’s Education and Outreach Grant Program in 2014 to convene a collaborative team to guide the production of online toolkits of educational materials and resources that community college instructors could use to teach about C-DEBI research and the deep biosphere. The project team consisted of 8 to 10 collaborators, including community college instructors, C-DEBI scientists, graduate students and postdoctoral scholars, technology experts, and science education specialists. The project drew from the 2013 C-DEBI online workshop “Microbes down below! Exploring life beneath the ocean floor” offered by the College of Exploration, which was specifically designed for community college instructors (see below). The online toolkits kits were designed to be aligned with specific community college course subjects and include materials and information that instructors can use to make connections between the topics in their curriculum and C-DEBI research, practices, or technology. The aim of this project was to reach a nationwide audience of community college instructors, and through them, hundreds to thousands of community college students, by making C-DEBI resources available free on line. These toolkits are presented at http://www.coexploration.org/C-DEBI for use by all.

Call for Nominations: BOEM Selects National Academies to Form Environmental Committee on Offshore Energy Resources
The Bureau of Ocean Energy Management (BOEM) announced today an agreement to have the National Academies establish a new standing committee on environmental science and assessment for offshore energy and mineral resources. The committee will provide independent information on issues relevant to BOEM’s environmental studies and assessment activities and support discussions on relevant issues. The committee’s services will be provided under a three-year contract with the National Research Council (NRC), the operating arm of the National Academy of Sciences (NAS) and the National Academy of Engineering (NAE). The NRC issued a call for nominations on June 23, 2015, seeking a broad pool of applicants for the standing committee. Nominations will be accepted by the NRC until July 15, 2015. The NRC expects to announce the committee membership  later in the summer, followed by an announcement of its plans for the first meeting in the fall of 2015.

University of Leicester: Earth Science Research Associate (IODP & other projects)
The College of Science and Engineering, Department of Geology at the University of Leicester invites applications for a Research Associate (Earth Scientist) to join an established team engaged in the acquisition and analysis of petrophysical core and borehole measurement data for the International Ocean Discovery Program (IODP) and other drilling/coring research projects. This is an exciting position that will provide the leading edge science needed for a future career in academia or the logging/petrophysical experience for a career in industry. The work is very much part of a team effort, though once an expedition is allocated, there is plenty of scope for independent activity. Applicants should ideally have a research background in at least one of the following areas: petrophysics, marine geology or geophysics. The position will include training as a Petrophysics Staff Scientist and will be responsible for the acquisition and scientific interpretation of core and borehole measurements, the production of scientific and technical reports, and the development of associated research programs. This research is a collaborative venture between the University of Leicester and a number of other universities and organizations in Europe, USA, Japan and other IODP member countries. This position will participate in IODP Mission Specific Platform expeditions, which include on average up to two months at sea and six weeks at the Bremen Core Repository (BCR, Germany) per year, with responsibility for the downhole logging and core physical properties programs for the expedition. The position has a fixed term contract from 1 September 2015 to 31 December 2016. Applications are due July 22, 2015. Click here and search on the reference number SEN00623 for more information and to apply.

Rice University: Wiess Post-Doctoral Research Fellowship in Earth and Planetary Science
The Department of Earth Science at Rice University is launching a Wiess Post-Doctoral Research Fellowship competition in the broad fields of Earth, atmospheric, and planetary sciences. Interested candidates should have recently completed their PhD or are expected to complete their PhD by September 2016. The appointment of the fellow is expected to begin anytime between July and December 2016. The principal selection criteria for the fellow are scientific excellence and a clearly expressed research plan to address questions at the forefront of Earth science, broadly defined. Applicants are expected to propose their own research ideas, but are encouraged to consider the current spectrum of research activities in the department and to communicate with one or more members of the faculty (http://earthscience.rice.edu/). The research fellowship will be supported by the Department of Earth Science for two years pending satisfactory progress in their first year. The fellowship covers an annual stipend of $60,000 and includes an annual research allowance of $3,500. The application deadline is November 1, 2015.
