Message from the Director
At last month’s C-DEBI Annual Meeting, our presently-funded research and education community met to discuss our current activities. The meeting was preceded by a graduate student and postdoctoral professional development workshop “Building Leadership in Science Communication” co-hosted by the Metcalf Institute for Marine & Environmental Reporting at the University of Rhode Island. See the agenda and resources.
Don’t forget to apply for our grants and fellowships due December 1, and perhaps we’ll meet you at next year’s Annual Meeting!

The role of nitrogen cycling in submarine hydrothermal systems is far less studied than that of other biologically reactive elements such as sulfur and iron. In order to address this knowledge gap, we investigated nitrogen redox processes at Loihi Seamount, Hawaii, using a combination of biogeochemical and isotopic measurements, bioenergetic calculations and analysis of the prokaryotic community composition in venting fluids sampled during four cruises in 2006, 2008, 2009 and 2013. Concentrations of NH4+ were positively correlated to dissolved Si and negatively correlated to NO3–+NO2–, while NO2– was not correlated to NO3–+NO2–, dissolved Si or NH4+. This is indicative of hydrothermal input of NH4+ and biological mediation influencing NO2– concentrations. The stable isotope ratios of NO3– (δ15N and δ18O) was elevated with respect to background seawater, with δ18O values exhibiting larger changes than corresponding δ15N values, reflecting the occurrence of both production and reduction of NO3– by an active microbial community. δ15N-NH4+ values ranged from 0‰ to +16.7‰, suggesting fractionation during consumption and potentially N-fixation as well. Bioenergetic calculations reveal that several catabolic strategies involving the reduction of NO3– and NO2– coupled to sulfide and iron oxidation could provide energy to microbes in Loihi fluids, while 16S rRNA gene sequencing of Archaea and Bacteria in the fluids reveals groups known to participate in denitrification and N-fixation. Taken together, our data support the hypothesis that microbes are mediating N-based redox processes in venting hydrothermal fluids at Loihi Seamount.
C-DEBI: Call for Research Project and Postdoctoral Fellowship Proposals
C-DEBI invites proposals for 1-year research projects (in the anticipated range of $50,000-$80,000) and 1-2 year graduate student and postdoctoral fellowships that will significantly advance C-DEBI’s central research agenda: to investigate the subseafloor biosphere deep in marine sediment and oceanic crust, and to conduct multi-disciplinary studies to develop an integrated understanding of subseafloor microbial life at the molecular, cellular, and ecosystem scales. C-DEBI’s research agenda balances exploration-based discovery, hypothesis testing, data integration and synthesis, and systems-based modeling. C-DEBI research support is provided to “expeditions of opportunity”, and we’ve created a webpage listing potential options for participation. We welcome you to provide information about other expeditions of opportunity to share with the C-DEBI community! Help us further our mission to explore life beneath the seafloor and make transformative discoveries that advance science, benefit society, and inspire people of all ages and origins. C-DEBI welcomes proposals from applicants who would enhance diversity in C-DEBI and STEM fields. This request for proposals is open to all interested researchers at US institutions able to receive NSF funding as a subaward. Proposal deadline: December 1, 2016.

MARUM: ECORD Training Course 2017, March 6-10, 2017, Bremen, Germany
As host to one of only three IODP core repositories in the world – the only one in Europe – the MARUM in Bremen is an important hub for marine geoscientists. Taking advantage of this setting, the new ECORD Training Course will provide a “Virtual Drillship Experience” for scientists from academia and industry. This one-week course offers a basic training focusing on the IODP core flow procedures, preparing the participants for sailing in an offshore drillship expedition, and instilling them with an appreciation for high standards in all kinds of coring projects. IODP-style lab exercises will form the foundation of the ECORD Training Course following the pattern of the unique “Virtual Ship” approach developed for the Bremen ECORD Summer Schools. The application deadline is January 9, 2017.
