Geochemistry measurements from the Strytan Hydrothermal Field Dataset Description: Methods and Sampling: <p>Samples were&nbsp;collected from 3 sites: Big Strytan, Arnarnasstrytan, and&nbsp;Hrisey&nbsp;(see lat/lon below). SCUBA diving was utilized to collect vent fluids and hydrothermal precipitates. Vent fluids for geochemistry were sampled in sterile 60 ml syringes. The first 20 ml was discarded to decrease the amount of seawater contamination during sampling. Vent fluid sampling for dissolved gases consisted of 2 methods: 1) the “syringe-to- syringe” method (STS), and 2) the “syringe-to-bottle” method (STB). The STS method consisted of pulling 40 ml of vent fluid at the end of a dive, transporting it back to the lab, and equilibrating the fluid with 20 ml of purified N2. The gas was then injected into Cali-5-Bond gas sampling bags for transport prior to analysis by GC. The STB method consisted of pulling a known volume of vent fluid (typically 40 ml) into a syringe, and immediately injecting into a 60 ml N2-flushed, evacuated, serum bottle.</p>
<p>Temperatures were measured in situ using a temperature probe. The pH/ORP/Conductivity/TDS were measured on shore using a Myron-L field pH meter. &nbsp;Samples for analysis of major cations and trace elements (Na, B, Mg, Si, K, Ca, Al, As, V, Cr, Cu, Zn, Sr, Mo, and W) were preserved in the field by filtering (0.2 um) and acidification with 0.1% ultrapure HNO3, and measured by inductively coupled plasma-mass spectrometry (ICP-MS).</p>

Center for Dark Energy Biosphere Investigations
The mission of the Center for Dark Energy Biosphere Investigations (C-DEBI) is 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 provides a framework for a large, multi-disciplinary group of scientists to pursue fundamental questions about life deep in the sub-surface environment of Earth. The fundamental science questions of C-DEBI involve exploration and discovery, uncovering the processes that constrain the sub-surface biosphere below the oceans, and implications to the Earth system. What type of life exists in this deep biosphere, how much, and how is it distributed and dispersed? What are the physical-chemical conditions that promote or limit life? What are the important oxidation-reduction processes and are they unique or important to humankind? How does this biosphere influence global energy and material cycles, particularly the carbon cycle? Finally, can we discern how such life evolved in geological settings beneath the ocean floor, and how this might relate to ideas about the origin of life on our planet?
C-DEBI's scientific goals are pursued with a combination of approaches:
(1) coordinate, integrate, support, and extend the research associated with four major programs—Juan de Fuca Ridge flank (JdF), South Pacific Gyre (SPG), North Pond (NP), and Dorado Outcrop (DO)—and other field sites;
(2) make substantial investments of resources to support field, laboratory, analytical, and modeling studies of the deep subseafloor ecosystems;
(3) facilitate and encourage synthesis and thematic understanding of submarine microbiological processes, through funding of scientific and technical activities, coordination and hosting of meetings and workshops, and support of (mostly junior) researchers and graduate students; and
(4) entrain, educate, inspire, and mentor an interdisciplinary community of researchers and educators, with an emphasis on undergraduate and graduate students and early-career scientists.
Note: Katrina Edwards was a former PI of C-DEBI; James Cowen is a former co-PI.
Data Management:
C-DEBI is committed to ensuring all the data generated are publically available and deposited in a data repository for long-term storage as stated in their Data Management Plan (PDF) and in compliance with the NSF Ocean Sciences Sample and Data Policy. The data types and products resulting from C-DEBI-supported research include a wide variety of geophysical, geological, geochemical, and biological information, in addition to education and outreach materials, technical documents, and samples. All data and information generated by C-DEBI-supported research projects are required to be made publically available either following publication of research results or within two (2) years of data generation.
To ensure preservation and dissemination of the diverse data-types generated, C-DEBI researchers are working with BCO-DMO Data Managers make data publicly available online. The partnership with BCO-DMO helps ensure that the C-DEBI data are discoverable and available for reuse. Some C-DEBI data is better served by specialized repositories (NCBI's GenBank for sequence data, for example) and, in those cases, BCO-DMO provides dataset documentation (metadata) that includes links to those external repositories.

A Lost City-type hydrothermal system in readily accessible, shallow water

A Lost City-type hydrothermal system in readily accessible, shallow water
<p>The Strytan Hydrothermal Field (SHF; Eyjafjord, northern Iceland) exhibits alkaline (pH ~ 10), hot (up to 78 degrees C), submarine hydrothermal venting, resulting in the formation of numerous saponite towers. We performed a detailed geochemical and microbiological characterization of hydrothermal fluids and precipitates from the site. End-member calculations revealed elevated concentrations of many major and trace elements (e.g., 2.4 mM Na, 3 to 27 uM K, 40 to 120 uM Ca, 10 to 25 uM B, and overall high concentrations of trace elements). We hypothesize that recharge of meteoric water occurs in the mountains south of Eyjafjord, and low temperature alteration of plagioclase, pyroxene and olivine in basalt, and precipitation of calcite, occurs in a closed system. This explains the observed high pH, variable Ca concentrations, and low DIC. CH4, H2, and CO concentrations were all elevated relative to normal seawater (up to 1.41, 5.19, and 0.13 uM, respectively), and a range of δ13C-CH4 was measured. Weathering of pyroxene may produce H2, which combines with CO2 to form abiotic CH4. The abiotic production of H2 and CH4 in a site such as the SHF broadens the range of potential origin of life environments significantly. Intact polar lipids indicate Bacteria dominated all samples except one. Up to 50% of the lipids at this site were archaeal. Bacterial clone sequences were dominated by betaproteobacteria (<em>Dechloromonas sp.</em>), followed by deltaproteobacteria (<em>Desulfovibrio sp.</em>) Archaeal results indicate a dominance of Crenarchaeota, particularly Thermoproteales, followed by <em>Desulfurococcales</em>. More detailed analysis of microbial communities is currently underway.</p>
