A dynamic microbial community with high functional redundancy inhabits the cold, oxic subseafloor aquifer NEW!
Benjamin J. Tully*, Charles Geoffrey Wheat*, Brian T. Glazer, Julie A. Huber*
*C-DEBI Contribution 395


The rock-hosted subseafloor crustal aquifer harbors a reservoir of microbial life that may influence global marine biogeochemical cycles. Here we utilized metagenomic libraries of crustal fluid samples from North Pond, located on the flanks of the Mid-Atlantic Ridge, a site with cold, oxic subseafloor fluid circulation within the upper basement to query microbial diversity. Twenty-one samples were collected during a 2-year period to examine potential microbial metabolism and community dynamics. We observed minor changes in the geochemical signatures over the 2 years, yet the microbial community present in the crustal fluids underwent large shifts in the dominant taxonomic groups. An analysis of 195 metagenome-assembled genomes (MAGs) were generated from the data set and revealed a connection between litho- and autotrophic processes, linking carbon fixation to the oxidation of sulfide, sulfur, thiosulfate, hydrogen, and ferrous iron in members of the Proteobacteria, specifically the Alpha-, Gamma- and Zetaproteobacteria, the Epsilonbacteraeota and the Planctomycetes. Despite oxic conditions, analysis of the MAGs indicated that members of the microbial community were poised to exploit hypoxic or anoxic conditions through the use of microaerobic cytochromes, such as cbb3- and bd-type cytochromes, and alternative electron acceptors, like nitrate and sulfate. Temporal and spatial trends from the MAGs revealed a high degree of functional redundancy that did not correlate with the shifting microbial community membership, suggesting functional stability in mediating subseafloor biogeochemical cycles. Collectively, the repeated sampling at multiple sites, together with the successful binning of hundreds of genomes, provides an unprecedented data set for investigation of microbial communities in the cold, oxic crustal aquifer.


Frontiers in Earth Science
Editorial: Deep Carbon in Earth: Early Career Scientist Contributions to the Deep Carbon Observatory NEW!
Donato Giovannelli*, Benjamin. A. Black, Alysia. D. Cox, Cody S. Sheik
*C-DEBI Contribution 396


Since its inception, the Deep Carbon Observatory (DCO) has coalesced a multidisciplinary and international group of researchers focused on understanding and quantifying Earth's deep carbon budget. Carbon is the fourth most abundant element in the universe, and understanding carbon chemistry under a variety of environmental conditions impacts all aspects of planetary sciences. DCO recognizes that contributions of early career scientists are integral to the advancement of knowledge regarding the quantities, movements, origins, and forms of Earth's deep carbon. This research topic highlights the contributions of the DCO Early Career Scientist community.

Expedition 366 Preliminary Report: Mariana Convergent Margin and South Chamorro Seamount NEW!
Patricia Fryer, Geoffrey Wheat, Trevor Williams, and the Expedition 366 Scientists


Geologic processes at convergent plate margins control geochemical cycling, seismicity, and deep biosphere activity in subduction zones and suprasubduction zone lithosphere. International Ocean Discovery Program (IODP) Expedition 366 was designed to address the nature of these processes in the shallow to intermediate depth of the Mariana subduction channel. Although no technology is available to permit direct sampling of the subduction channel of an intraoceanic convergent margin at depths up to 18 km, the Mariana forearc region (between the trench and the active volcanic arc) provides a means to access this zone.

C-DEBI: Rolling call for Community Workshop support
The NSF Science and Technology Center for Dark Energy Biosphere Investigations (C-DEBI) invites proposals for $15,000 on average (and up to $20,000) in direct funds for community workshops that will help to 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.

IODP: Apply to Sail on IODP Expedition 358 NEW!
The International Ocean Discovery Program (IODP) is now accepting applications for Expedition 358 NanTroSEIZE Plate Boundary Riser 4 aboard the D/V Chikyu. The expedition is currently planned to begin on 7 October 2018 and finish on 21 March 2019 (164 days). This expedition is planned for more than five months at sea and therefore will not be staffed in the standard expedition “shipboard scientific party” model. Opportunities exist for researchers (including graduate students) to sail on the expedition. Scientists with interest and expertise in: fault zone structure and mechanics, accretionary complex geology and evolution, lithostratigraphy, physical and hydrogeological properties, diagenetic/metamorphic processes and effects, micropaleontology, microbiology, rock magnetism, and core-log-seismic integration in structurally-complex settings are all invited to apply. Because of the nature of the drilling operation and need for near-real time analysis, expertise in the use of drill cuttings, mud gas, and modern well logging to address sedimentary petrology, structure, physical properties and geomechanics are all especially useful. The deadline to apply is January 4, 2018.

C-DEBI: Rolling call for Research Exchange proposals
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 $500-5000 with additional matched funds to be granted annually.
