attribute	NC_GLOBAL	acquisition_description	String	Seawater (~180 L) was collected from the stable hydrothermal vent plume issuing from the black smoker chimney Inferno (CTD17, 1 450 m). Whole water was transferred to clean 50 L polystyrene reservoirs and concentrated to ~230 ml with a Pellicon 2 tangential flow filtration system equipped with a 30 kDa Biomax Polyethersulfone cassette (Millipore Corporation, Billerica, MA) as described previously (Morris et al 2010). Cells were collected and concentrated in approximately 2 hours. Concentrated cells were flash frozen in liquid nitrogen and stored at -80 \u00baC until further processing at the University of Washington.Cell counts before and after filtration (6.9 x 1010 and 2.9 x 1010, respectively) indicate that we recovered 42% of the cells present in 180 L of hydrothermal vent plume water. Cells in the concentrated sample were divided into replicate samples (Av1 and Av2, ~115 ml each) and harvested by centrifuging at 4\u00b0C for 60 min (17,000 x g). The supernatant was discarded and cell pellets were rinsed with 100 uL of 20 mM Tris buffer pH 7.4 and stored -80\u00b0C. Cells were lysed using a titanium sonicating micro-probe (20 sec, 10 repetitions) in a 6M urea and 50 \u03bcM ammonium bicarbonate solution. Disulfide bonds were reduced with dithiothreitol and alkylated with iodo- acetic acid. After additions of ammonium bicarbonate and methanol, 2 \u03bcg of sequence grade trypsin (Promega, Madison, WI) were added to each sample. Enzymatic digestions were incubated for 12 h at 37 oC. Resulting peptides were desalted using a macro-spin C18 column (NestGroup) following the manufacturers guidelines prior to analysis by mass spectrometry (MS). Peptide concentrations from Axial volcano hydrothermal vent plume proteome replicates Av1 and Av2 were measured using the Thermo Scientific Nanodrop 2000/2000c, which measures the peptide bond absorbance at wavelength of 205 nm. Approximately 1 \u03bcg of peptide digest was used for each injection into the mass spectrometer. Each sample consisted of a complex mixture of peptides that were introduced into the mass spectrometer by reverse-phase chromatography using a brand new 15 cm long, 75 \u03bcm i.d. fused silica capillary column packed with C18 particles (Magic C18AQ, 100 \u00c5, 5 \u03bcm; Michrom, Bioresources, Inc., CA) fitted with a 2 cm long, 100 \u03bcm i.d. pre-column (Magic C18AQ, 200 \u00c5, 5\u03bcm; Michrom). Peptides were first trapped on the pre-column (5% ACN; 4 ml min-1; 7 min). Chromatographic separations were performed using an acidified (formic acid, 0.1% v/v) water- acetonitrile gradient (5-35% acetonitrile in 60 min) with a total run-time of 95 minutes. Mass spectrometry was performed on replicates Av1 and Av2 independently using the Thermo Fisher (San Jose, Ca) linear ion trap \u2013Orbitrap (LTQ-OT) hybrid tandem mass spectrometer. Peptides were analyzed using the data- independent Precursor Acquisition Independent from Ion Count (PAcIFIC) method (Panchaud et al 2009). Rather than requiring the mass spectrometer to select ions for fragmentation based on MS1 data, the PAcIFIC method systematically fragments ions at all m/z channels (Panchaud et al 2011). Each method file includes the full 95 minute linear HPLC gradient of 5-35% ACN over 60 minutes (see above) and covers a 21.5 m/z range using 14 contiguous, unique channels that span 2.5 m/z in the mass spectrometer. This results in a total of 45 method files per PAcIFIC analytical cycle to cover a full m/z range of 400-1400.

attribute	NC_GLOBAL	instruments_0_description	String	The Sea-Bird SBE 9 is a type of CTD instrument package. The SBE 9 is the Underwater Unit and is most often combined with the SBE 11 Deck Unit (for real-time readout using conductive wire) when deployed from a research vessel. The combination of the SBE 9 and SBE 11 is called a SBE 911. The SBE 9 uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 and SBE 4). The SBE 9 CTD can be configured with auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorometer, altimeter, etc.). Note that in most cases, it is more accurate to specify SBE 911 than SBE 9 since it is likely a SBE 11 deck unit was used. more information from Sea-Bird Electronics

attribute	NC_GLOBAL	instruments_1_dataset_instrument_description	String	"The hybrid Fourier Transform (FT) mass spectrometer(MS) combines a linear ion trap MS and the Orbitrap mass analyzer. Ions generated by API are collected in the LTQ XL followed by axial ejection to the C-shaped storage trap which is used to store and collisionally cool ions before injection into the orbital trap. The ions transferred from the C-Trap are captured in the orbital trap by rapidly increasing the electric field and the detection of the image current from coherent ion packets takes place after the voltages have stabilized. Signals from each of the orbital trap outer electrodes are amplified and transformed into a frequency spectrum by fast Fourier transformation which is finally converted into a mass spectrum."

attribute	NC_GLOBAL	projects_0_description	String	Description from NSF award abstract: The ocean serves an immense reservoir of carbon, nitrogen, phosphorus, sulfur, and other elements required for all life. The active and diverse microbial populations that inhabit the oceans are responsible for mediating nutrient transformations that maintain the chemistry of seawater. A recent study identified a ubiquitous group of marine bacteria from the Arctic96BD-19 gamma-proteobacterial sulfur oxidizer (GSO) lineage that is closely related to known sulfur oxidizing species that fix inorganic carbon and oxidize sulfide in low-oxygen waters. The potential for GSOs to use reduced forms of sulfur in oxygenated waters suggests that they are a keystone species that link the marine carbon and sulfur cycles. The only known isolates from the Arctic96BD-19 lineage of GSOs are now in culture, allowing fundamental questions about their roles in carbon and sulfur cycling to be investigated. Preliminary data suggest that they use energy from the oxidation of sulfur to assimilate carbon. This project seek to address the overarching hypothesis that sulfur transformations provide the Arctic96BD- 19 lineage of GSOs with energy for organic and inorganic carbon cycling throughout the water column. Three specific hypotheses will be tested. 1. Arctic96BD-19 cells assimilate either organic carbon or fixes inorganic carbon, depending on environmental conditions. 2. Arctic96BD-19 cells oxidize thiosulfate via formation of a tetrathionate intermediate, or using the branched thiosulfate oxidation pathway. 3. Arctic96BD-19 cells are ubiquitous sulfur oxidizers that assimilate organic and inorganic carbon through the Pacific Northwest. A combination of laboratory growth studies of the investigator's pure cultures and comparative genomic analyses will be used. The genomic data will be used to determine whether the Arctic96BD-19 cultures possess the genetic potential to oxidize reduced sulfur to sulfate (based on possession of known core and ancillary sulfur oxidation genes), which potential oxidation pathways are used, and whether they can fix inorganic carbon. These data will help guide the physiology studies by determining the most likely forms of inorganic and organic compounds that can be utilized. Marine bacteria are critical players in global nutrient cycles, but many of their individual and community functions in the ecosystem are not well understood. Future oceanographers will need to use cultivation-dependent and cultivation-independent methods to identify metabolic process that shape microbial communities and impact biogeochemical cycles. Student education, scientific advancement, and public awareness are all important components of this project.
