attribute NC_GLOBAL acquisition_description String Samples were collected seasonally at the San Pedro Ocean Time-series (SPOT)\nstation at four depths (surface, subsurface chlorophyll maximum, 150 and 890\nm).\\u00a0The SPOT station was sampled from 5 m, the subsurface chlorophyll\nmaximum (SCM), 150 and 890 m using 10 L Niskin bottles mounted on a CTD\nrosette, during regularly scheduled cruises\n([https://dornsife.usc.edu/spot/](\\\\\"https://dornsife.usc.edu/spot/\\\\\")).\n \nSeawater from all samples was sequentially pre-filtered through 200 \\u03bcm\nand 80 \\u03bcm Nitex mesh to reduce abundances of multicellular eukaryotes\n(metazoa). Near-surface and SCM seawater (2 L) and 150 and 890 m seawater (4\nL) was filtered onto GF/F filters (nominal pore size 0.7 \\u03bcm; Whatman,\nInternational Ltd, Florham Park, NJ, USA) and immediately flash frozen in\nliquid nitrogen for later DNA and RNA extraction.\n \nTotal DNA and RNA were extracted simultaneously from each sample using the All\nPrep DNA/RNA Mini kit (Qiagen, Valencia, CA, USA, #80204). Genomic DNA was\nremoved during the RNA extraction with RNase-Free DNase reagents (Qiagen,\n#79254). Total extracted RNA was checked for residual genomic DNA by\nperforming a polymerase chain reaction (PCR) using DNA specific primers to\nensure that no amplified products appeared when run on an agarose gel. RNA was\nreverse transcribed into cDNA using iScript Reverse Transcription Supermix\nwith random hexamers (Bio-Rad Laboratories, Hercules, CA, USA, #170-8840).\n \nThe resulting cDNA and DNA from each sample were PCR amplified using V4\nforward (5\\u2032\\u00a0-CCAGCA[GC]C[CT]GCGGTA ATTCC-3\\u2032\\u00a0) and reverse\n(5\\u2032\\u00a0-ACTTTCGTTCTTGAT[CT][AG]A-3\\u2032\\u00a0) primers (Stoeck et al.\n2010). Duplicate PCR reactions were performed in 50 \\u03bcL volumes of: 1X\nPhusion High-Fidelity DNA buffer, 1 unit of Phusion DNA polymerase (New\nEngland Biolabs, Ipswich, MA, USA, #M0530S), 200 \\u03bcM of dNTPs, 0.5 \\u03bcM\nof each V4 forward and reverse primer, 3% DMSO, 50 mM of MgCl and 5 ng of\neither DNA or cDNA template per reaction. The PCR thermal cycler program\nconsisted of a 98\\u25e6C denaturation step for 30 s, followed by 10 cycles of\n10 s at 98\\u25e6C, 30 s at 53\\u25e6C and 30 s at 72\\u25e6C, and then 15 cycles\nof 10 s at 98\\u25e6C, 30 s at 48\\u25e6C and 30 s at 72\\u25e6C, and a final\nelongation step at 72\\u25e6C for 10 min, as described in Rodr\\u0131\n\\u0301guez-Mart\\u0131 \\u0301nez et al. (2012). PCR products were purified\n(Qiagen, #28104) and duplicate samples were pooled. The \\u223c400 bp cDNA and\nDNA PCR products were quality checked on an Agilent Bioanalyzer 2100 (Agilent\nTechnologies, Santa Clara, CA).\n \nSampling Locations:  \n SPOT (33\\u25e6 33\\u2032 N, 118\\u25e6 24\\u2032 W) - surface, DCM, 150 m, and\n890 m  \n Port of LA (33\\u25e6 42.75\\u2032 N, 118\\u25e6 15.55\\u2032 W) - surface  \n Catalina (33\\u25e6 27.17\\u2032 N, 118\\u25e6 28.51\\u2032 W)-surface\n \nFor protocols see:  \n[https://www.protocols.io/view/sample-collection-from-the-field-for-\ndownstream-mo-hisb4ee](\\\\\"https://www.protocols.io/view/sample-collection-\nfrom-the-field-for-downstream-mo-hisb4ee\\\\\")  \n[https://www.protocols.io/view/rna-and-optional-dna-extraction-from-\nenvironmental-hk3b4yn](\\\\\"https://www.protocols.io/view/rna-and-optional-dna-\nextraction-from-environmental-hk3b4yn\\\\\")  \n[https://www.protocols.io/view/18s-v4-tag-sequencing-pcr-amplification-and-\nlibrar-hdmb246](\\\\\"https://www.protocols.io/view/18s-v4-tag-sequencing-pcr-\namplification-and-librar-hdmb246\\\\\")

attribute NC_GLOBAL instruments_2_dataset_instrument_nid String 745568
attribute NC_GLOBAL instruments_2_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 Planktonic marine microbial communities consist of a diverse collection of bacteria, archaea, viruses, protists (phytoplankton and protozoa) and small animals (metazoan). Collectively, these species are responsible for virtually all marine pelagic primary production where they form the basis of food webs and carry out a large fraction of respiratory processes. Microbial interactions include the traditional role of predation, but recent research recognizes the importance of parasitism, symbiosis and viral infection. Characterizing the response of pelagic microbial communities and processes to environmental influences is fundamental to understanding and modeling carbon flow and energy utilization in the ocean, but very few studies have attempted to study all of these assemblages in the same study. This project is comprised of long-term (monthly) and short-term (daily) sampling at the San Pedro Ocean Time-series (SPOT) site. Analysis of the resulting datasets investigates co-occurrence patterns of microbial taxa (e.g. protist-virus and protist-prokaryote interactions, both positive and negative) indicating which species consistently co-occur and potentially interact, followed by examination gene expression to help define the underlying mechanisms. This study augments 20 years of baseline studies of microbial abundance, diversity, rates at the site, and will enable detection of low-frequency changes in composition and potential ecological interactions among microbes, and their responses to changing environmental forcing factors. These responses have important consequences for higher trophic levels and ocean-atmosphere feedbacks. The broader impacts of this project include training graduate and undergraduate students, providing local high school student with summer lab experiences, and PI presentations at local K-12 schools, museums, aquaria and informal learning centers in the region. Additionally, the PIs advise at the local, county and state level regarding coastal marine water quality.\nThis research project is unique in that it is a holistic study (including all microbes from viruses to small metazoa) of microbial species diversity and ecological activities, carried out at the SPOT site off the coast of southern California. In studying all microbes simultaneously, this work aims to identify important ecological interactions among microbial species, and identify the basis(es) for those interactions. This research involves (1) extensive analyses of prokaryote (archaean and bacterial) and eukaryote (protistan and micro-metazoan) diversity via the sequencing of marker genes, (2) studies of whole-community gene expression by eukaryotes and prokaryotes in order to identify key functional characteristics of microorganismal groups and the detection of active viral infections, and (3) metagenomic analysis of viruses and bacteria to aid interpretation of transcriptomic analyses using genome-encoded information. The project includes exploratory metatranscriptomic analysis of poorly-understood aphotic and hypoxic-zone protists, to examine their stratification, functions and hypothesized prokaryotic symbioses.
