attribute NC_GLOBAL acquisition_description String Nutrient analysis\n \n\\u00a0\n \nNutrient samples were filtered through 0.22 \\u03bcm pore size\nDurapore\\u00a0GVWP filters (Millipore Sigma) and frozen at \\u221220_C\nimmediately\\u00a0after collection, then stored at \\u221280_C until\nanalysis.\\u00a0Dissolved nitrate (NO3\\u00a0\\u2212), nitrite (NO2\\u00a0\\u2212),\nphosphate (PO4\\u00a03\\u2212), and\\u00a0silicate (SiO4\\u00a04\\u2212) were\nmeasured using a Bran and Luebbe AA3\\u00a0autoanalyzer as described previously\n(Wilkerson et al. 2015).\\u00a0Ammonium and urea were measured manually using\nthe\\u00a0phenolhypochlorite method (Sol\\u00f3rzano 1969) and the\ndiacetylmonoxime\\u00a0method (Rahmatullah and Boyde 1980; Mulvenna\\u00a0and\nSavidge 1992), respectively.\\u00a0\n \nOxidation rate measurements\\u00a0\n \nWe used 15N-labeled substrates (98\\u201399% 15N, Cambridge\\u00a0Isotope\nLaboratories) to measure the oxidation of N supplied\\u00a0as NH4+, urea,\n1,2-diaminoethane (DAE), 1,3-diaminopropane\\u00a0(DAP), 1,4-diaminobutane\n(putrescine, PUT), L-glutamic acid\\u00a0(GLU), and L-arginine (ARG). 15N\noxidation from NH4+, urea,\\u00a0PUT, and GLU were measured extensively,\nwhereas 15N oxidation\\u00a0from DAE, DAP, and ARG was only measured at a\nsubset\\u00a0of stations (Supporting Information Table S1). GLU and\nARG\\u00a0were included as a control for remineralization, as their\ncentral\\u00a0roles in microbial metabolism leads to rapid catabolism\nand\\u00a0NH4\\u00a0+ regeneration (Hollibaugh 1978; Goldman et al.\n1987).\\u00a0PUT was used in routine assessments of the oxidation\nof\\u00a0polyamine-N because it is one of the most consistently\ndetected\\u00a0polyamines in seawater (Nishibori et al. 2001a, 2003; Lu\\u00a0et\nal. 2014; Liu et al. 2015). Although spermine and spermidine\\u00a0are also\ncommon in seawater, 15N-labeled stocks of these polyamines\\u00a0were not\ncommercially available. We measured the oxidation\\u00a0of N from DAE and DAP\nto investigate the effect of\\u00a0aliphatic chain length (which affects pKa)\non oxidation rate.\\u00a0\n \nDuplicate seawater samples contained in 1-liter polycarbonate\\u00a0or 250 mL\nhigh density polyethylene (HDPE) bottles\\u00a0wrapped with aluminum foil (to\nexclude light) were\\u00a0amended with 10\\u201350 nM 15N-labeled substrate.\nMarsh\\u00a0Landing samples were then placed in an incubator held at\\u00a0in\nsitu temperature in the dark. Samples taken at the Skidaway\\u00a0dock were\nplaced in a mesh bag and immersed at the\\u00a0sea surface at the sampling\nsite. Samples collected at sea\\u00a0were incubated in a tank of flowing\nsurface seawater or in an\\u00a0incubator held at 18 C in the dark. Incubation\nbottles were sampled\\u00a0for 15N analysis immediately after substrate\naddition and\\u00a0again after a period of ~ 24 h. 15N samples were subsampled\ninto\\u00a050 mL polypropylene centrifuge tubes, frozen at \\u221220_C,\nand\\u00a0stored at \\u221280_C until analysis. The 15N/14N ratios of the\nNO3\\u00a0\\u2212\\u00a0plus NO2\\u00a0\\u2212 (NOX) pools (\\u03b415NNOx) in the\nsamples were measured\\u00a0using the bacterial denitrifier method to convert\nNOX to nitrous\\u00a0oxide (N2O; Sigman et al. 2001). The \\u03b415N values of\nthe N2O\\u00a0produced were measured using a Finnigan MAT-252\nisotope\\u00a0ratio mass spectrometer coupled with a modified GasBench II\ninterface (Casciotti et al. 2002; Beman et al. 2011; McIlvin\\u00a0and\nCasciotti 2011). Oxidation rates were calculated using an\\u00a0endpoint model\n(Beman et al. 2011; Damashek et al. 2016).\\u00a0Since the substrates used were\nuniformly labeled with 15N, the\\u00a0amount of the N added as the 15N spike\n(in \\u03bcM) was multiplied\\u00a0by the number of moles of 15N per mole of\nsubstrate, which\\u00a0assumes that all of the N atoms have equal probability\nof being\\u00a0oxidized. This is likely true for urea, DAE, DAP, and PUT,\nwhich\\u00a0are symmetrical molecules, but not likely to be true for\nARG,\\u00a0which contains 4 N atoms (one in the \\u03b1-amino position\nand\\u00a0three in the guanidine structure of its R-group). Abiotic\noxidation\\u00a0of organic N was assessed by measuring 15NOX\nproduction\\u00a0following 15N amendment and incubation of 0.22 \\u03bcm\nfiltered\\u00a0seawater (as described above), and potential metabolism\nof\\u00a0DON by the denitrifying bacteria used to convert NOX to N2O\\u00a0was\nchecked by adding 15N-labeled substrates into the bacterial\\u00a0cultures\nprior to mass spectrometry.\\u00a0\n \nWe were unable to measure the in situ concentrations of\\u00a0the individual\ncomponents of DON used in oxidation experiments,\\u00a0other than urea. Based\non previous measurements\\u00a0made in the SAB (Lu et al. 2014; Liu et al.\n2015), we assumed\\u00a0concentrations of 1 nM and 0.25 nM for DAE, DAP and\nPUT,\\u00a0and 10 nM and 5 nM for GLU and ARG, at inshore and\\u00a0mid-shelf\n/shelf-break/oceanic stations, respectively. Rates of\\u00a0polyamine and amino\nacid oxidation reported below should\\u00a0therefore be considered potential\nrates, as amendments as low\\u00a0as 10\\u201350 nM are likely to increase\nsubstrate concentrations\\u00a0substantially above in situ. Initial substrate\n15N activity was\\u00a0calculated using isotope mass balance using the known\nconcentration\\u00a0and 15N activity of the labeled substrates added\\u00a0and\nassuming the concentrations described above and natural\\u00a0abundance 15N\nactivity (i.e., 0.3663 atom% 15N).\\u00a0

attribute NC_GLOBAL instruments_0_dataset_instrument_description String Water from multiple depths was collected using 12-liter Niskin bottles mounted on a rosette equipped with a Sea-Bird SBE25 CTD. Profiles of salinity, temperature, dissolved oxygen, fluorescence, and photosynthetically active radiation (PAR) were collected using the CTD system as described previously (Liu et al. 2018).
attribute NC_GLOBAL instruments_0_dataset_instrument_nid String 767193
attribute NC_GLOBAL instruments_0_description String The Sea-Bird SBE 25 SEALOGGER CTD is battery powered and is typically used to record data in memory, eliminating the need for a large vessel, electrical sea cable, and on-board computer. All SBE 25s can also operate in real-time, transmitting data via an opto-isolated RS-232 serial port. Temperature and conductivity are measured by the SBE 3F Temperature sensor and SBE 4 Conductivity sensor (same as those used on the premium SBE 9plus CTD). The SBE 25 also includes the SBE 5P (plastic) or 5T (titanium) Submersible Pump and TC Duct. The pump-controlled, TC-ducted flow configuration significantly reduces salinity spiking caused by ship heave, and in calm waters allows slower descent rates for improved resolution of water column features. Pressure is measured by the modular SBE 29 Temperature Compensated Strain-Gauge Pressure sensor (available in eight depth ranges to suit the operating depth requirement). The SBE 25's modular design makes it easy to configure in the field for a wide range of auxiliary sensors, including optional dissolved oxygen (SBE 43), pH (SBE 18 or SBE 27), fluorescence, transmissivity, PAR, and optical backscatter sensors.

attribute NC_GLOBAL projects_0_acronym String DON Oxidation
attribute NC_GLOBAL projects_0_description String NSF Abstract:\nNitrogen is an essential nutrient for phytoplankton that often limits primary production in the ocean, and its availability therefore plays a key role in global ocean productivity. The amounts and form in which nitrogen exist are controlled by microorganisms. One microorganism-mediated process is known as nitrification, which oxidizes ammonia or ammonium to nitrite and nitrite to nitrate, nitrate being the bioavailable form of nitrogen. While this is the well-accepted process of nitrification, preliminary results strongly suggest that a nitrogen-containing compound know as polyamine nitrogen may be directly converted by some microorganisms to nitrate. However, the importance of this process for global biogeochemical nitrogen cycling is unknown. The goal of this study is to evaluate the biogeochemical significance of direct oxidation of polyamine nitrogen, as a model organic nitrogen compound, to nitrification compared to canonical nitrification of ammonia. The project will result in training a postdoctoral researcher and provide opportunities for undergraduates to gain hands-on experience with research on microbial geochemistry and coastal ecosystem processes. Project personnel will also work with the Georgia Coastal Ecosystems Long-Term Ecological Research program to engage a K-12 science teacher in the project.\nAmmonia oxidation is a key step in the process of converting fixed nitrogen to dinitrogen gas and thus is central to the global nitrogen cycle and to removing excess fixed nitrogen from coastal waters with high concentrations of nutrients. Recent research has shown that Thaumarchaeota play a major role in ammonia oxidation in the ocean. Experiments with enrichment cultures and coastal water samples where ammonia oxidizing archaea are the dominant ammonia oxidizers, show that some forms of organic nitrogen may be oxidized directly to nitrogen oxides without first being regenerated as ammonium. Of the substrates tested, polyamine and particularly putrescine nitrogen appear to be oxidized directly to nitrogen oxides, while amino acid and urea nitrogen is first regenerated as ammonium and then oxidized. The investigators will examine this process in detail over three years using enrichment cultures and experiments conducted with coastal bacterioplankton. Specifically, they will aim to better understand 1) the consequences of this novel process to ocean geochemistry, 2) the fate of the carbon present in polyamines, 3) what organisms are responsible for the direct oxidation, and 4) the chemical characteristics of the organic nitrogen compounds accessible to direct oxidation.
