NCBI accession numbers describing nifH amplicon sequences from sediment samples collected offshore of San Francisco, Califronia, USA in March 2017 on R/V Oceanus cruise OC1703A

Abstract:

These data are raw, demultiplexed nifH amplicon sequences generated from Illumina MiSeq for the investigation of potential diazotroph diversity along a continental margin transect. Raw Illumina MiSeq 2×250 bp sequence data can be accessed in the NCBI SRA database under accession numbers ERP130242 and ERP120468 and BioProject accession numbers PRJEB46054 and PRJEB37167. Data under accession number ERP120468 and BioProject accession number PRJEB37167 were published in Kapili and Dekas, 2021. The generation of these data was completed on June 29, 2021.

Methods & Sampling

Sediment samples were collected using a multicorer on board the R/V Oceanus (March 2017) and sample aliquots were immediately stored at -80°C until DNA extraction. DNA was extracted in the laboratory using an RNeasy PowerSoil DNA elution kit (Qiagen, catalog no. 12867-25) after RNA was extracted using an RNeasy PowerSoil Total RNA kit. (Qiagen, catalog no. 12866-25).

nifH sequences were amplified using the PCR primers described in Mehta et al., 2003 and amplicons were prepared for 2×250 bp sequencing on an Illumina MiSeq platform following the protocol described in Kapili et al., 2020.

Data Processing Description

Data Processing:
Samples were demultiplexed at the UC Davis DNA Technologies Core facility.

BCO-DMO Processing:
- replaced "na" with "nd" (no data)

Instruments

Automated DNA Sequencer

Supplied Name: Illumina MiSeq platform

Supplied Description:

Instrument Type

Generic Name: Automated DNA Sequencer

Acronym: Automated Sequencer

Generic Description:

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.

Multi Corer

Supplied Name: MC-800

Supplied Description:

Instrument Type

Generic Name: Multi Corer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/51/

Generic Description:

The Multi Corer is a benthic coring device used to collect multiple, simultaneous, undisturbed sediment/water samples from the seafloor. Multiple coring tubes with varying sampling capacity depending on tube dimensions are mounted in a frame designed to sample the deep ocean seafloor. For more information, see Barnett et al. (1984) in Oceanologica Acta, 7, pp. 399-408.
