GLU and ARG\u00a0were included as a control for remineralization, as their central\u00a0roles in microbial metabolism leads to rapid catabolism and\u00a0NH4\u00a0+ regeneration (Hollibaugh 1978; Goldman et al. 1987).\u00a0PUT was used in routine assessments of the oxidation of\u00a0polyamine-N because it is one of the most consistently detected\u00a0polyamines in seawater (Nishibori et al. 2001a, 2003; Lu\u00a0et al. 2014; Liu et al. 2015). Although spermine and spermidine\u00a0are also common in seawater, 15N-labeled stocks of these polyamines\u00a0were not commercially available. We measured the oxidation\u00a0of N from DAE and DAP to investigate the effect of\u00a0aliphatic chain length (which affects pKa) on oxidation rate.\u00a0 Duplicate seawater samples contained in 1-liter polycarbonate\u00a0or 250 mL high density polyethylene (HDPE) bottles\u00a0wrapped with aluminum foil (to exclude light) were\u00a0amended with 10\u201350 nM 15N-labeled substrate. Marsh\u00a0Landing samples were then placed in an incubator held at\u00a0in situ temperature in the dark. Samples taken at the Skidaway\u00a0dock were placed in a mesh bag and immersed at the\u00a0sea surface at the sampling site. Samples collected at sea\u00a0were incubated in a tank of flowing surface seawater or in an\u00a0incubator held at 18 C in the dark. Incubation bottles were sampled\u00a0for 15N analysis immediately after substrate addition and\u00a0again after a period of ~ 24 h. 15N samples were subsampled into\u00a050 mL polypropylene centrifuge tubes, frozen at \u221220_C, and\u00a0stored at \u221280_C until analysis. The 15N/14N ratios of the NO3\u00a0\u2212\u00a0plus NO2\u00a0\u2212 (NOX) pools (\u03b415NNOx) in the samples were measured\u00a0using the bacterial denitrifier method to convert NOX to nitrous\u00a0oxide (N2O; Sigman et al. 2001). The \u03b415N values of the N2O\u00a0produced were measured using a Finnigan MAT-252 isotope\u00a0ratio mass spectrometer coupled with a modified GasBench II interface (Casciotti et al. 2002; Beman et al. 2011; McIlvin\u00a0and Casciotti 2011). Oxidation rates were calculated using an\u00a0endpoint model (Beman et al. 2011; Damashek et al. 2016).\u00a0Since the substrates used were uniformly labeled with 15N, the\u00a0amount of the N added as the 15N spike (in \u03bcM) was multiplied\u00a0by the number of moles of 15N per mole of substrate, which\u00a0assumes that all of the N atoms have equal probability of being\u00a0oxidized. This is likely true for urea, DAE, DAP, and PUT, which\u00a0are symmetrical molecules, but not likely to be true for ARG,\u00a0which contains 4 N atoms (one in the \u03b1-amino position and\u00a0three in the guanidine structure of its R-group). Abiotic oxidation\u00a0of organic N was assessed by measuring 15NOX production\u00a0following 15N amendment and incubation of 0.22 \u03bcm filtered\u00a0seawater (as described above), and potential metabolism of\u00a0DON by the denitrifying bacteria used to convert NOX to N2O\u00a0was checked by adding 15N-labeled substrates into the bacterial\u00a0cultures prior to mass spectrometry.\u00a0 We were unable to measure the in situ concentrations of\u00a0the individual components of DON used in oxidation experiments,\u00a0other than urea. Based on previous measurements\u00a0made in the SAB (Lu et al. 2014; Liu et al. 2015), we assumed\u00a0concentrations of 1 nM and 0.25 nM for DAE, DAP and PUT,\u00a0and 10 nM and 5 nM for GLU and ARG, at inshore and\u00a0mid-shelf /shelf-break/oceanic stations, respectively. Rates of\u00a0polyamine and amino acid oxidation reported below should\u00a0therefore be considered potential rates, as amendments as low\u00a0as 10\u201350 nM are likely to increase substrate concentrations\u00a0substantially above in situ. Initial substrate 15N activity was\u00a0calculated using isotope mass balance using the known concentration\u00a0and 15N activity of the labeled substrates added\u00a0and assuming the concentrations described above and natural\u00a0abundance 15N activity (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_description	String	NSF Abstract: Nitrogen 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. Ammonia 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.
