attribute NC_GLOBAL acquisition_description String Experimental seawater collection: For shipboard bioassay experiments, whole\nseawater and resident biota were collected from ~4 m depth whilst underway at\n~5 knots, using a trace-metal clean towfish system (Sedwick et al., 2011).\nThis seawater was used to fill two 60 L polyethylene carboys in parallel\ninside a shipboard trace-metal clean container laboratory, after passing\nthrough pre-cleaned 180 \\u00b5m nylon screen to exclude larger organisms, then\nsubsequently used to fill the experimental incubation bottles (see below).\nThree bioassay experiments were performed (Sedwick et al., 2018), for which\nseawater was collected during three separate deployments of the towfish\nsystem.\n \nFor bioassay experiment 1, seawater was collected on 1 August, 2014, between\n16:55 and 17:35 local time, between 38.6053\\u00b0N, 72.2534\\u00b0W (start) and\n38.5692\\u00b0N, 72.2354\\u00b0W (end). Single determinations of iron and\nmacronutrient concentrations in seawater from the towfish that was filtered\nin-line through a 0.8/0.2 \\u00b5m AcroPak Supor filter capsule (Pall) yielded\nthe following results:\n \nDissolved iron (DFe): 0.55 nM (start), 0.43 nM (end)\n \nDissolved nitrate+nitrite (NO3+NO2): 0.07 \\u00b5M (start) 0.08 \\u00b5M (end)\n \nDissolved phosphate (PO4): 0.19 \\u00b5M (start), 0.20 \\u00b5M (end)\n \nDissolved ammonium (NH4): not determined\n \nFor bioassay experiment 2, seawater was collected on 4 August, 2014, between\n11:10 and 12:10 local time, between 38.3800\\u00b0N, 72.4743\\u00b0W (start) and\n38.3847\\u00b0N, 72.4761\\u00b0W (end).

Single determinations of iron and\nmacronutrient concentrations in seawater from the towfish that was filtered\nin-line through a 0.8/0.2 \\u00b5m AcroPak Supor filter capsule (Pall) yielded\nthe following results:\n \nDissolved iron (DFe): 0.89 nM (start), 0.90 nM (end)\n \nDissolved nitrate+nitrite (NO3+NO2): 0.05 \\u00b5M (start) 0.07 \\u00b5M (end)\n \nDissolved phosphate (PO4): not determined\n \nDissolved ammonium (NH4): 0.03 \\u00b5M (start), 0.01 \\u00b5M (end)\n \nBioassay experiment protocols: The shipboard bioassay experimental protocols\nare described by Sedwick et al. (2018). For each experiment there were 6\ndifferent incubation treatments (control, iron, nitrate, nitrate+iron,\nnitrate+iron+phosphate, rainwater), with triplicate bottles for each treatment\nsampled at each of three timepoints. Each bottle was completely subsampled for\nmeasurements of nutrients (NO3+NO2, NH4), chlorophyll-a and primary\nproductivity. For the initial (time = 0) measurements, the seawater that\nremained in the 60 L polyethylene carboys after filling the incubation bottles\nwas transfered into a 20 L polyethylene carboy from which subsamples were\ntaken for measurements of NO3+NO2 after filtration through 0.8 \\u00b5m pore\nsize AcroDisc Supor syringe filters (Pall), for chlorophyll-a after filtration\non to combusted 0.7 \\u00b5m pore size GF/F filters (Whatman), and for\nincubation with carbon-13 labeled bicarbonate for estimation of primary\nproduction. For initial (t = 0) NH4 concentrations, we use mean values\nmeasured in seawater sampled from the towfish outlet after in-line filtration\n(see above).\n \nAnalytical procedures:\n \nDFe: Filtered seawater samples were acidified at-sea to pH ~1.8 with Fisher\nOptima grade ultrapure hydrochloric acid, and then stored at room temperature\nuntil post-cruise analysis at Old Dominion University. Dissolved iron was\ndetermined by flow injection analysis with colorimetric detection after in-\nline preconcentration on resin-immobilized 8-hydroxyquinoline (Sedwick et al.,\n2015), using a method modified from Measures et al. (1995). Analyses were\nperformed on a volumetric basis, so concentrations are reported in units of\nnanomole liter-1 (nM). Analytical precision is estimated from multiple\n(separate-day) determinations of the SAFe seawater reference materials, which\nyield uncertainties (expressed as one relative standard deviation on the mean,\nor one sigma) of ~15% at the concentration level of SAFe S seawater (0.090\nnM), and ~10% at the concentration level of SAFe D2 seawater (0.90 nM). The\nanalytical limit of detection is estimated as the DFe concentration equivalent\nto a peak area that is three times the standard deviation on the zero-loading\nblank (manifold blank), which yields an estimated detection limit below 0.04\nnM (Bowie et al., 2004). Blank contributions from the ammonium acetate sample\nbuffer solution (added on-line during analysis) and hydrochloric acid (added\nafter collection) are negligible.\\t\n \nNO3+NO2: Dissolved nitrate and nitrite was determined at sea using an Astoria\nPacific nutrient autoanalyzer using standard colorimetric methods with an\nestimated detection limit of 0.14 \\u00b5M (Parsons et al., 1984; Price and\nHarrison, 1987). In surface waters, nitrate and nitrite were determined using\nthe same autoanalyzer equipped with a liquid waveguide capillary cell (World\nPrecision Instruments) (Zhang, 2000) to achieve an estimated detection limit\nof 0.02 \\u00b5M.\n \nPO4: Dissolved phosphate was determined at sea using an Astoria Pacific\nnutrient autoanalyzer using standard colorimetric methods with an estimated\ndetection limit of 0.03 \\u00b5M (Parsons et al., 1984; Price and Harrison,\n1987).\\t\\t\n \nNH4: Dissolved ammonium was determined at sea using the manual\northophthaldialdehyde method (Holmes et al., 1999), with an estimated\ndetection limit of 10 nM.\n \nChl-a: Chlorophyll-a was determined at sea using the non-acidification method\nwith a Turner 10-AU fluorometer (Welschmeyer, 1994).\n \nPP: Primary production was measured using carbon stable istopes (Mulholland et\nal., 2006).\n \nMissing data identifiers:  \n ND = not determined (single measurement)  \n NR = not reported (contamination likely, only used for NH4 data)

attribute NC_GLOBAL projects_0_description String NSF abstract:\nDeposition of atmospheric nitrogen provides reactive nitrogen species that influence primary production in nitrogen-limited regions. Although it is generally assumed that these species in precipitation contributes substantially to anthropogenic nitrogen loadings in many coastal marine systems, its biological impact remains poorly understood. Scientists from Pennsylvania State University, William & Mary College, and Old Dominion University will carry out a process-oriented field and modeling effort to test the hypothesis that deposits of wet atmospheric nitrogen (i.e., precipitation) stimulate primary productivity and accumulation of algal biomass in coastal waters following summer storms and this effect exceeds the associated biogeochemical responses to wind-induced mixing and increased stratification caused by surface freshening in oligotrophic coastal waters of the eastern United States. To attain their goal, the researchers would perform a Lagrangian field experiment during the summer months in coastal waters located between Delaware Bay and the coastal Carolinas to determine the response of surface-layer biogeochemistry and biology to precipitation events, which will be identified and intercepted using radar and satellite data. As regards the modeling effort, a 1-D upper ocean mixing model and a 1-D biogeochemical upper-ocean will be calibrated by assimilating the field data obtained a part of the study using the adjoint method. The hypothesis will be tested using sensitivity studies with the calibrated model combined with in-situ data and results from the incubation experiments. Lastly, to provide regional and historical context for the field measurements and the associated 1-D modeling, linked regional atmospheric-oceanic biogeochemical modeling will be conducted.\nBroader Impacts. Results from the study would be incorporated into class lectures for graduate courses on marine policy and marine biogeochemistry. One graduate student from Pennsylvania State University, one graduate student from the College of William and Mary, and one graduate and one undergraduate student from Old Dominion University would be supported and trained as part of this project.
