attribute NC_GLOBAL acquisition_description String Sampling of cores was done in accordance with IODP protocols.\n \nAll C0014 samples were cored on 16 September 2010 via via HPCS (hydraulic\npiston coring system).  \n All C0015 samples were cored on 18 September 2010 via HPCS.  \n All C0017 samples were cored on 27 September 2010 via HPCS.\n \nCore sections were kept frozen (-80\\u00b0C) until DNA extractions. RNA was\nextracted using a phenol chloroform protocol. The RNA extract was DNAse\ntreated using the Invitrogen\\u2122 Ambion\\u2122 Turbo DNA-free Kit and\npurified using the Qiagen\\u00ae RNeasy Mini Kit. A cDNA library was made using\nthe Qiagen \\u00ae QuantiTec Reverse Transcription Kit. Polymerase chain\nreactions used the KAPABiosystems\\u00ae KAPA2G Robust HotStart ReadyMix PCR\nKit for 32 cycles.\n \nSequencing of the product was performed on the Illumina\\u00ae MiSeq 2500.

attribute NC_GLOBAL instruments_0_description String General term for a laboratory instrument used for deciphering the order of bases in a strand of DNA. Sanger sequencers detect fluorescence from different dyes that are used to identify the A, C, G, and T extension reactions. Contemporary or Pyrosequencer methods are based on detecting the activity of DNA polymerase (a DNA synthesizing enzyme) with another chemoluminescent enzyme. Essentially, the method allows sequencing of a single strand of DNA by synthesizing the complementary strand along it, one base pair at a time, and detecting which base was actually added at each step.

attribute NC_GLOBAL projects_0_description String The Iheya North Hydrothermal Field in the Okinawa Backarc Basin represents an ideal environment in which to investigate the biotic temperature fringe of microbial life at depth because of its subsurface hydrothermal activity within its continental margin-type sediment profile. Geographically, the Okinawa Backarc Basin is situated along a continental margin, which is a sediment profile type commonly sampled and studied across the seafloor (e.g. Peru Margin, Costa Rica Margin, Cascadia Margin). The hydrothermal network within the subsurface here supplies an additional temperature obstacle to microbial life existing in the sediments. In particular, the sediment profile at Site C0014 exhibits a transition from hemipelagic ooze with pumiceous volcaniclastic sediments and low temperature (4°C) to a hydrothermally altered sequence of clays within the top ~10 mbsf of sediment. Temperature measurements indicate a gradient of approximately 3°C/m, which is roughly an order of magnitude greater than continental margin sites (e.g. Cascadia Margin, IODP 311 and Costa Rica Margin, IODP 344), but is more gradual than intense, centimeter-scale gradients from other hot, surface sediments. We have focused on the application of culture-independent, molecular methods to understand taxonomic and functional characteristics through this hydrothermal gradient. Confidence in DNA recovery suggests a microbial biosphere extent of approximately 15 mbsf (55°C).\nResults from both 16S rRNA gene surveys and metagenomics analyses suggest a temperature-dependent stratigraphy of taxonomic and functional adaptations between the shallowest and deepest sample horizons. Cosmopolitan marine subsurface bacterial and archaeal taxa are present throughout the top 10 mbsf, whereas, hyperthermophilic heterotrophic as well as thermophilic anaerobic methanotrophic archaea appear in varying local abundances in deeper, hydrothermal clay horizons. \"An In-Depth analysis of the subvent biosphere within Okinawa Backarc Basin (IODP 331, Iheya North Hydrothermal Field) sediments\" encompasses datasets funded through C-DEBI to investigate the microbial communities in IODP 331 Iheya North Hydrothermal Field sediments. Site C0014 at this field site is 500 m away from the active vent and experiences a 3C/m temperature gradient with depth. In the research grant \"Investigating the active microbial populations in near hydrothermal vent sediments\" and the Research Exchange grant \"Learning new RNA extraction techniques\", we used an RNA-based approach to explore the active microbial community. Upon analysis, the RNA dataset does not appear to reflect the same information as the phylogenetic signals coming from both the 16S rRNA gene as well as the metagenomes. The data indicate significant background noise from the RNA extraction process rather than from an indigenous representation of the subsurface biosphere.\nThe graduate fellowship \"An in-depth analysis of the subvent biosphere within the Okinawa backarc basin Iheya North hydrothermal field\" provided an opportunity to bring together metagenomic, 16S rRNA gene amplicon (DNA), and 16S rRNA amplicon datasets from IODP 331 Iheya North Hydrothermal Field sediments to understand the biogeography of this subvent biosphere.\nFor more information, refer to the following C-DEBI grants/projects.\nAn in-depth analysis of the subvent biosphere within the Okinawa backarc basin Iheya North hydrothermal field:https://www.darkenergybiosphere.org/award/an-in-depth-analysis-of-the-subvent-biosphere-within-the-okinawa-backarc-basin-iheya-north-hydrothermal-field/\nInvestigating the active microbial populations in near hydrothermal vent sediments: https://www.darkenergybiosphere.org/award/investigating-the-active-microbial-populations-in-near-hydrothermal-vent-sediments/\nLearn new RNA extraction techniques: https://www.darkenergybiosphere.org/award/learn-new-rna-extraction-techniques/

attribute NC_GLOBAL summary String RNA extractions were attempted from sediments at Sites C0014 and C0017 to selectively investigate the active microbial populations at these sites. This study was conducted to supplement the gene-based and metagenomic studies. However, the results from sequenced reverse transcribe 16S rRNA demonstrate the sensitivity of extraction and amplification to external nucleic acids and attest to the challenges in working with low biomass environmental samples. Inconsistencies between primersets and replicates make conclusions about the results of this RNA study extremely tenuous.
