attribute NC_GLOBAL acquisition_description String Sampling and Analytical Methodology: Freshly collected sediment cores were\nsliced on the ship into 3 cm layers; porewater was obtained by gently\ncentrifuging freshly collected sediment in 50 ml conical Falcon tubes for ca.\n5 to 10 minutes until the sediment had settled; one Falcon tube produced ca. 8\nto 10 ml of porewater. For porewater sulfate measurements, 1 ml subsamples of\nthe overlying porewater were drawn into syringes and injected through 0.45\n\\u03bcm filters into screw cap Eppendorf vials, each acidified with 50 \\u00b5l\nof 6N HCl, and then gently bubbled with nitrogen for 4 min to remove sulfide;\nthe samples were then stored at 4\\u00baC before shipping and analysis.\n \nGeochemical Analyses:\\u00a0SO4 was analyzed on a Dionex ICS-1000 using a RFIC\nIonPac AS22 4 X 250mm column and a RFIC IonPac AG22 Guard column 4 X 50 mm.\nThe IC was calibrated using a 5 point std curve and a minimum r^2 value of\n0.999. The MDL measured at 0.10 ppm SO4. A check standard from a 1000 ppm was\nmade fom a Dionex 7 anion standard to a concentration of 15 ppm. An external\nStandard from HACH 100 ppm SO4 was used to make a 20 ppm QC standard. In\ngeneral, QCs were analyzed for 10% of the samples.\n \nData Processing: The porewater data of Guaymas Basin sand Sonora Margin piston\ncores were tabulated in Excel sheets.\n \nQuality Control: Note that Sample_IDs \\\"D7A_10X_CKS\\\" are internal quality\ncontrol standards (15.5 mg/L) and\\u00a0Sample_IDs \\\"DI_SPK\\\" are external\nquality control standards (20.0 mg/L).

attribute NC_GLOBAL instruments_1_description String Ion chromatography is a form of liquid chromatography that measures concentrations of ionic species by separating them based on their interaction with a resin. Ionic species separate differently depending on species type and size. Ion chromatographs are able to measure concentrations of major anions, such as fluoride, chloride, nitrate, nitrite, and sulfate, as well as major cations such as lithium, sodium, ammonium, potassium, calcium, and magnesium in the parts-per-billion (ppb) range.

attribute NC_GLOBAL projects_0_description String Description from NSF award abstract:\nHydrothermally active sediments in the Guaymas Basin are dominated by novel microbial communities that catalyze important biogeochemical processes in these seafloor ecosystems. This project will investigate genomic potential, physiological capabilities and biogeochemical roles of key uncultured organisms from Guaymas sediments, especially the high-temperature anaerobic methane oxidizers that occur specifically in hydrothermally active sediments (ANME-1Guaymas). The study will focus on their role in carbon transformations, but also explore their potential involvement in sulfur and nitrogen transformations. First-order research topics include quantifying anaerobic methane oxidation under high temperature,in situ concentrations of phosphorus and methane , and with alternate electron acceptors; sulfate and sulfur-dependent microbial pathways and isotopic signatures under these conditions; and nitrogen transformations in methane-oxidizing microbial communities, hydrothermal mats and sediments.\nThis integrated biogeochemical and microbiological research will explore the pathways of and environmental controls on the consumption and production of methane, other alkanes, inorganic carbon, organic acids and organic matter that fuel the Guaymas sedimentary microbial ecosystem. The hydrothermal sediments of Guaymas Basin provide a spatially compact, high-activity location for investigating novel modes of methane cycling and carbon assimilation into microbial biomass. In the case of anaerobic methane oxidation, the high temperature and pressure tolerance of Guaymas Basin methane-oxidizing microbial communities, and their potential to uncouple from the dominant electron acceptor sulfate, vastly increase the predicted subsurface habitat space and biogeochemical role for anaerobic microbial methanotrophy in global deep subsurface diagenesis. Further, microbial methane production and oxidation interlocks with syulfur and nitrogen transformations, which will be explored at the organism and process level in hydrothermal sediment microbial communities and mats of Guaymas Basin. In general, first-order research tasks (rate measurements, radiotracer incorporation studies, genomes, in situ microgradients) define the key microbial capabilities, pathways and processes that mediate chemical exchange between the subsurface hydrothermal/seeps and deep ocean waters.\nPublications associated with this project are as follows:\nNote: this is now a list of all publications that use samples collected from the NSF-funded Guaymas cruises AT15-40 and AT15-56. All these publications were funded from NSF award OCE-0647633, the grant that funded these two cruises. Those publications that were written and published after 2013 continue to use samples collected and analyzed on cruises AT15-40 and AT15-56 under NSF award OCE-0647633, but the effort in analyzing the data and writing the manuscript also relied on funding by OCE-1357238. Since we will not have new samples until late in 2016, current work and publications on OCE-1357238 will continue to rely on samples collected during cruises AT15-40 and AT15-56.\nHoller, T. F.
