C-DEBI Special Call for Deep Biosphere Research Proposals
C-DEBI invites proposals for one-year projects that will significantly advance our central research agenda—to investigate the subseafloor biosphere deep in sediments and the crust. C-DEBI intends to fund 2-3 proposals in response to this call, up to $100,000 each. Proposals will be considered for research on subseafloor samples, participation on upcoming expeditions (including C-DEBI field programs, IODP expeditions and other field opportunities relevant to C-DEBI objectives), and shore-based investigations. Proposed research can also focus on theoretical and experimental deep biosphere studies in a broader sense, which might include, for example, testing novel techniques for deep biosphere research, lab-based experiments with deep biosphere organisms, model development, and metabolic studies of growth under deep subsurface conditions. Fundamental studies of microbial metabolism that can be applied to subsurface conditions will also be considered. In this call, we especially encourage proposals with one of the following foci:
- Synthesis and integration of datasets that link microbiological processes to environmental conditions. A primary goal should be to provide insight into microbial activity, connectivity, limits, evolution, or survival in deep subseafloor ecosystems.
- Analysis of or experimentation with samples from a recent or upcoming field program with clear C-DEBI research objectives (e.g., North Pond cruise April 2014, Juan de Fuca Ridge flank cruise in August 2014, Guaymas Basin cruise in October 2014, Dorado Outcrop cruise in November 2014, North Atlantic long-coring expedition in October-December 2014, new site surveys in preparation of subsequent drilling).

NSF: Genealogy of Life (GoLife) program solicitation
Comprehensive understanding of life and how and why it changes over time depends on knowledge of the phylogeny (evolutionary relationships) of living and extinct organisms. The goals of the Genealogy of Life (GoLife) program are to resolve the phylogenetic history of all life’s diverse forms and to integrate this genealogical architecture with underlying organismal and environmental data. The ultimate vision of this program is an open access, comprehensive Genealogy of Life that will provide the comparative framework necessary for testing questions in systematics, evolutionary biology, ecology, and other fields. Strategic integration of this genealogy of life with data layers from genomic, phenotypic, spatial, ecological and temporal data will produce an extensive synthesis of biodiversity and evolutionary sciences. The resulting knowledge infrastructure will enable synthetic research on biological dynamics throughout the history of life on Earth, within current ecosystems, and for predictive modeling of the future evolution of life. Projects submitted to this program should emphasize increased efficiency in contributing to a complete Genealogy of Life and strategic integration of various types of organismal and environmental data with phylogenies. This program also seeks to broadly train next generation, integrative phylogenetic biologists, creating the human resource infrastructure and workforce needed to tackle emerging research questions in comparative biology. Projects should train students for diverse careers by exposing them to the multidisciplinary areas of research within the proposal. Full proposal deadline: March 25, 2015.
NSF: Dear Colleague Letter: Removal of deadlines for program solicitations within the Surface Earth Processes Section of the Division of Earth Sciences in the Directorate for Geosciences
A primary objective of research support provided by the National Science Foundation (NSF) is to transform the boundaries of scientific understanding. To meet this objective, after the upcoming January 2015 deadlines, new solicitations will be released for programs in the Surface Earth Processes Section within the Division of Earth Sciences. These new solicitations will no longer require that proposals be submitted by a specific deadline. Beginning on April 16th, 2015 investigators will be allowed to submit proposals at any time. Despite this change, programs in the Surface Earth Processes Section will continue to maintain high-quality merit review through the use of panel and ad hoc reviews, as has been the practice in the Division of Earth Sciences for many years. Only solicitations for the Geobiology & Low-temperature Geochemistry, Hydrologic Sciences, Geomorphology & Land-use Dynamics, and Sedimentary Geology & Paleobiology Programs will be affected by this change. All other submissions will continue to follow deadlines outlined in their respective solicitations.

IODP-USSSP: Proposals for Pre-Drilling Activities and Workshops

The deep subsurface is an enormous repository of microbial life. However, the metabolic capabilities of these microorganisms and the degree to which they are dependent on surface processes are largely unknown. Due to the logistical difficulty of sampling and inherent heterogeneity, the microbial populations of the terrestrial subsurface are poorly characterized. In an effort to better understand the biogeochemistry of deep terrestrial habitats, the authors, including C-DEBI researcher LaRowe and director Amend, evaluate the energetic yield of chemolithotrophic metabolisms and microbial diversity in the Sanford Underground Research Facility (SURF) in the former Homestake Gold Mine, SD, USA. Geochemical data, energetic modeling, and DNA sequencing were combined with principle component analysis to describe this deep (down to 8100 ft below surface), terrestrial environment. SURF provides access into an iron-rich Paleoproterozoic metasedimentary deposit that contains deeply circulating groundwater. Geochemical analyses of subsurface fluids reveal enormous geochemical diversity ranging widely in salinity, oxidation state (ORP 330 to −328 mV), and concentrations of redox sensitive species (e.g., Fe2+ from near 0 to 6.2 mg/L and Σ S2- from 7 to 2778μg/L). As a direct result of this compositional buffet, Gibbs energy calculations reveal an abundance of energy for microorganisms from the oxidation of sulfur, iron, nitrogen, methane, and manganese. Pyrotag DNA sequencing reveals diverse communities of chemolithoautotrophs, thermophiles, aerobic and anaerobic heterotrophs, and numerous uncultivated clades. Extrapolated across the mine footprint, these data suggest a complex spatial mosaic of subsurface primary productivity that is in good agreement with predicted energy yields. Notably, they report Gibbs energy normalized both per mole of reaction and per kg fluid (energy density) and find the later to be more consistent with observed physiologies and environmental conditions. Further application of this approach will significantly expand our understanding of the deep terrestrial biosphere.
Hot Off the Press: Further insights into how sediment redox status controls the preservation and composition of sedimentary biomarkers (C-DEBI Contribution 237) in Organic Geochemistry
Sedimentary biomarker distributions can record ocean productivity and community structure, but their interpretation must consider alteration during organic matter (OM) export and burial. Large changes in the water column redox state are known to impact on the preservation of biomarkers, but more subtle variation in sediment redox conditions, characteristic of major modern ocean basins, have been less thoroughly investigated. Here the authors, including C-DEBI researcher LaRowe, evaluate changes in biomarker distributions during sinking and burial across a nearshore to offshore transect in the southwestern Cape Basin (South East Atlantic), which includes a range of sedimentary environments. Biomarker concentrations and distributions in suspended particulate matter from the upper water column were determined and compared with underlying sedimentary biomarker accumulation rates and distributions. Biomarker distributions were similar in surface and subsurface waters, indicating that the OM signature is exported from the ocean mixed layer with minimal alteration. They show that, while export production (100 m) is similar along this transect, 230Thxs-corrected biomarker accumulation rate varies by over an order of magnitude in sediments and is directly associated with sedimentary redox conditions, ranging from oxic to nitrogenous–ferruginous. Biomarker distributions were dominated by sterols in surface water, and by alkenones in underlying sediments, which we propose to be primarily the result of selective preservation. Notably, the difference in sediment O2 penetration depth was associated with relative biomarker preservation. Subtle variation in sedimentary redox conditions has a dramatic impact on the distribution of preserved biomarkers. They discuss mechanisms for preferential degradation of specific biomarkers within this setting.
Hot Off the Press: Sulfate reduction and methane oxidation activity below the sulfate-methane transition zone in Alaskan Beaufort Sea continental margin sediments: Implications for deep sulfur cycling (C-DEBI Contribution 239) in Geochimica et Cosmochimica Acta
Two ∼6 m long sediment cores were collected along the ∼300 m isobath on the Alaskan Beaufort Sea continental margin. Both cores showed distinct sulfate-methane transition zones (SMTZ) at 105 and 120 cm below seafloor (cmbsf). Sulfate was not completely depleted below the SMTZ but remained between 30 and 500 μM. Sulfate reduction and anaerobic oxidation of methane (AOM) determined by radiotracer incubations were active throughout the methanogenic zone. Although a mass balance could not explain the source of sulfate below the SMTZ, geochemical profiles and correlation network analyses of biotic and abiotic data suggest a cryptic sulfur cycle involving iron, manganese and barite. Inhibition experiments with molybdate and 2-bromoethanesulfonate (BES) indicated decoupling of sulfate reduction and AOM and competition between sulfate reducers and methanogens for substrates. While correlation network analyses predicted coupling of AOM to iron reduction, the addition of manganese or iron did not stimulate AOM. Since none of the classical archaeal anaerobic methanotrophs (ANME) were abundant, the involvement of unknown or unconventional phylotypes in AOM is conceivable. The resistance of AOM activity to inhibitors implies deviation from conventional enzymatic pathways. This work, authors including C-DEBI researcher Hamdan, suggests that the classical redox cascade of electron acceptor utilization based on Gibbs energy yields does not always hold in diffusion-dominated systems, and instead biotic processes may be more strongly coupled to mineralogy.
