Methods & Sampling

AT15-38: Samples for SAGs were obtained using the so-called 'titanium major samplers' (von Damm et al, 1985). Replicate samples of 1 ml aliquots of water were cryopreserved with 6% glycine betaine (Sigma) or 15% glycerol and stored at -80 ºC for the ”Single Cell” aliquot.

AT26-10: Background samples were obtained from the IGTs, in which the incubations were carried out. Just in this case, an aliquot was removed after sample retrieval and before starting the incubation. During AT26-10, samples were preserved with Gly-TE and stored at -80.

Cells were sorted, identified and sequenced by the Bigelow Laboratory Single Cell Genomics FacilityCenter (SCGC), following SCGCthe facilities’s standard practices: SCGC_Services_Description.pdf

Data Processing Description

On average, at least 5 million 2x150 bp or longer paired-end reads were generated per SAG using in-house MiSeq and NextSeq (Illumina) instruments. The obtained reads were pre-processed and, de novo, assembled and quality-controlled using algorithms SCGC's standard protocols that are optimized for single cell MDA products . A combination of tetramer homogeneity tests and blast searches against reference databases is used to detect potential DNA contaminants among the assembled contigs. Benchmark data demonstrating SCGC SAG WGS whole genome sequencing pipeline performance is available from the SCGC website http://data.bigelow.org/~scgc/WGS_benchmark_data/.

Genome annotation was performed through IMG (http://img-stage.jgi-psf.org/cgi-bin/submit/main.cgi).

Instruments

Automated DNA Sequencer

Supplied Name:

Supplied Description:

MiSeq and NextSeq (Illumina) sequencers

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.

Isobaric Gas-Tight Sampler

Supplied Name: IGT

Supplied Description:

Instrument Type

Generic Name: Isobaric Gas-Tight Sampler

Acronym: IGT Sampler

Generic Description:

Isobaric Gas Tight (IGT) samplers, designed and built by scientists and engineers at WHOI, are titanium instruments designed to be used with deep submergence vehicles to sample corrosive hydrothermal vent fluids at high temperature and high pressure. The IGT prevents the sampled fluid from degassing as pressure decreases during the vehicle’s ascent to the surface.

ROV Jason

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: ROV Jason

Generic Description:

The Remotely Operated Vehicle (ROV) Jason is operated by the Deep Submergence Laboratory (DSL) at Woods Hole Oceanographic Institution (WHOI). WHOI engineers and scientists designed and built the ROV Jason to give scientists access to the seafloor that didn't require them leaving the deck of the ship. Jason is a two-body ROV system. A 10-kilometer (6-mile) fiber-optic cable delivers electrical power and commands from the ship through Medea and down to Jason, which then returns data and live video imagery. Medea serves as a shock absorber, buffering Jason from the movements of the ship, while providing lighting and a bird’s eye view of the ROV during seafloor operations. During each dive (deployment of the ROV), Jason pilots and scientists work from a control room on the ship to monitor Jason’s instruments and video while maneuvering the vehicle and optionally performing a variety of sampling activities. Jason is equipped with sonar imagers, water samplers, video and still cameras, and lighting gear. Jason’s manipulator arms collect samples of rock, sediment, or marine life and place them in the vehicle’s basket or on "elevator" platforms that float heavier loads to the surface. More information is available from the operator site at URL.
