The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Illumina sequencing data from sediment strata collected from the cold seeps of Hydrate Ridge, metalliferous sediments of Juan de Fuca Ridge, and organic-rich hydrothermal sediments of Guaymas Basin from 2013-01-01 to 2014-04-01 (NCEI Accession 0291304) |
| Abstract: | This dataset contains biological data collected in the Gulf of California and North Pacific Ocean from 2013-01-01 to 2014-04-01. These data include taxon. The instruments used to collect these data include PCR Thermal Cycler. These data were collected by Dr Peter Girguis of Harvard University as part of the "Collaborative Research: The Role of Iron-oxidizing Bacteria in the Sedimentary Iron Cycle: Ecological, Physiological and Biogeochemical Implications (SedimentaryIronCycle)" project and "Center for Dark Energy Biosphere Investigations (C-DEBI)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-03-15. The following is the text of the dataset description provided by BCO-DMO: Acquisition Description: This study included cold seep and hydrothermal vent sediments from along the Pacific coast of North America. Sediments were collected via 30 cm long polycarbonate pushcores from a cold methane seep at Hydrate Ridge (44°34'10. 20"N, 125° 8'48. 48"W) at 777 m water depth with the ROV Ropos (Dive 1458); hydrothermal vents at Guaymas Basin, Gulf of California (27°0'27.84"N, 111°24'27.84"W) at 2000 m with the DSV Alvin (Dive 4486); and hydrothermal vents at Middle Valley, Juna de Fuca Ridge (48°27'26.40"N, 128°42'30.60"W) at 2413 m with the DSV Alvin (Dive 4625). For this study, a total of three pushcores were collected from Hydrate Ridge at 4°C, one from Guaymas Basin at 30-35°C, and one from Middle Valley at 5–57°C (Table 4.1). Total genomic DNA was extracted using a phenol-chloroform protocol modified to prevent nucleic acid loss and eliminate potential inhibitors of downstream PCR, and which has been very successful in studies of low biomass sediments (Adams et al. 2013). PCR amplification was performed with primers designed to be universal to both archaea and bacteria (515F/806R) (Caporaso et al., 2012), containing attached Illumina adaptors and barcodes (Kozich et al., 2013). All DNA extracts were amplified in duplicate with OmniTaq (Taq mutant) polymerase according to the manufacturer’s instructions (DNA Polymerase Technologies, St. Louis, MO, USA), with a final concentration of 0.2 μM for each primer. For each PCR, 1 μL template DNA was added to the final reaction mixture for a final volume of 50 μl. Amplification conditions were as follows: 94°C for 3 min to denature DNA; 30 cycles at 94°C for 45 s, 50°C for 60 s, and 72°C for 60 s; and a final extension of 10 min at 72 °C. |
