Microbial life inhabiting subseafloor sediments plays an important role in Earth’s carbon cycle. However, the impact of geodynamic processes on the distributions and carbon-cycling activities of subseafloor life remains poorly constrained. We explore a submarine mud volcano of the Nankai accretionary complex by drilling down to 200 m below the summit. Stable isotopic compositions of water and carbon compounds, including clumped methane isotopologues, suggest that ~90% of methane is microbially produced at 16° to 30°C and 300 to 900 m below seafloor, corresponding to the basin bottom, where fluids in the accretionary prism are supplied via megasplay faults. Radiotracer experiments showed that relatively small microbial populations in deep mud volcano sediments (102 to 103 cells cm−3) include highly active hydrogenotrophic methanogens and acetogens. Our findings indicate that subduction-associated fluid migration has stimulated microbial activity in the mud reservoir and that mud volcanoes may contribute more substantially to the methane budget than previously estimated.

NOAA: Ocean Exploration and Research Funding Opportunity - NEW!
NOAA’s Office of Ocean Exploration & Research (OER) is soliciting proposals for ocean exploration in waters under U.S. jurisdiction, including the U.S. Exclusive Economic Zone (EEZ), and areas mapped by, or of interest to, the U.S. Extended Continental Shelf (ECS) Project. Presently, important marine habitats and living and non-living resources are neither fully explored nor characterized. OER’s intent is to address these knowledge gaps and support growth in the Nation’s Blue Economy by soliciting ocean exploration proposals that focus on: 1. Discovering microorganisms, sponges, corals, and other organisms with biopharmaceutical or biotechnical potential; 2. Acquiring baseline ocean environmental information to better inform decision-making where future ocean energy development or critical mineral extraction may occur; 3. Finding and characterizing shipwrecks and submerged cultural resources that played a role in America’s past ocean-based economy (e.g., transport, trade, warfare, etc.) and could inform decisions on future seabed activities and potential environmental impacts. The deadline for the pre-proposal submission is July 26, 2018.

U South Florida: Two Tenure-Track Faculty Positions in Chemical and Geological Oceanography - NEW!
The University of South Florida College of Marine Science, located in Saint Petersburg, Florida, is actively seeking to fill two open rank positions in oceanography. 1) We seek a Geological Oceanographer whose research complements the strengths of the current faculty. We seek a hypothesis-driven scientist who uses a process-based approach to understand problems central to the ocean and its connections to the Earth systems. The candidate will use innovative techniques to investigate the effects of environmental change on the evolution of the stratigraphic record over a broad range of spatial and temporal scales. 2) We seek a Chemical Oceanographer who will contribute to an understanding of the ocean/climate system, from basic disciplinary topics to ecosystems analyses. Qualified candidates will employ modern tools of multi-disciplinary science to understand regional and global issues critical to the ocean system. The positions are open until filled, however, priority review of applications will begin by August 1, 2018. Appointment is anticipated to commence August 1, 2019.

The Center for Environmental Biotechnology (CEB) is seeking an enthusiastic, highly motivated postdoctoral research associate to apply cutting edge metagenomics methods. The position is available starting immediately for one year, with possible renewal for another year upon mutual agreement and availability of funds. Screening of applicants will begin immediately and applications will be considered until the position is filled. The post-doc will apply novel metagenomics methods to study microbial communities in permafrost aquatic sediments of different ages to uncover microbial biodiversity in young to ancient permanently frozen sediments with respect to survivability, metabolic adaptation and evolutionary changes. The research will take place in a highly collaborative environment with access to state-of-the-art instrumentation and computational resources within the CEB’s Next-Gen Illumina Sequencing Lab, Bioimaging Core Facility, and Bioinformatics Resource Center. The researcher will have opportunities to gain experience in other approaches related to microbial community research, give presentations and write proposals, as well as providing practical supervision of PhD candidates and undergraduate student
U Lyon: Postdoctoral research associate in environmental microbiology – biogeochemistry - NEW!
The Laboratory of Geology of Lyon (Université Lyon 1 & ENS de Lyon, France) invites applications for a postdoctoral research associate in environmental microbiology – biogeochemistry. The project is part of the multi-disciplinary consortium Science For Clean Energy (S4CE) funded by the European Union’s Horizon 2020 research and innovation programme. S4CE has been established to understand the underlying mechanisms underpinning sub-surface geo-energy operations and to measure, control and mitigate their environmental risks. The PDRA will work in close collaboration with an international group of scientists on deciphering the role of the subsurface biosphere in the C, N and S biogeochemical cycles affecting energy-generating geo-operations. Research focuses on the analysis of the metabolic activity of key microorganisms that develop at depth in geothermal wells and CO2/H2S injection wells for enhanced geothermal energy (EGT) and carbon capture sequestration (CCS), respectively. Sampling of underground fluids is scheduled at two sites in 2018. The goal of the project is to characterize the metabolism of key microorganisms under subsurface conditions. The research involves the cultivation of various microbial strains of relevance for the sampled subsurface environments under simulated conditions of the subsurface (high pressure and/or high temperature). A unique pressure facility is available at the LGL allowing monitoring of metabolic reactions using in situ spectroscopy. The candidate should hold a PhD in microbiology with expertise in environmental microbiology and microbial physiology. An experience in microscopy and spectroscopy is appreciated but not required. Complete applications will be reviewed every two weeks, starting now, until the position is filled.
U Hawaii: Postdoctoral Fellowship in Molecular biogeochemistry of dissolved organic phosphorus production, composition, and bioavailability - NEW!
