attribute NC_GLOBAL acquisition_description String [The following methodology applies where dataset parameter \"sample_source\" is\n\"UNDERWAY\"]\n \nNear-surface sample collection: Near-surface (~4 m depth) seawater was\ncollected whilst underway at ~5 knots using a trace-metal clean towfish system\n[Sedwick et al., 2011]. The subsamples for analysis of DFe, NO3+NO2, PO4 were\ntaken directly from the towfish line, after filtration through a 0.8/0.2\n\\u00b5m AcroPak Supor filter capsule (Pall), in acid-cleaned 125 mL low-\ndensity polyethylene bottles (Nalgene) for shore-based DFe determinations, and\n60 mL polypropylene tubes (Falcon) for shipboard NO3+NO2, PO4 and NH4\nanalyses.\n \nNear-surface underway measurements: Continuous underway measurements of near-\nsurface seawater temperature, salinity and chlorophyll fluorescence were made\nusing the ship's underway seawater supply, which is pumed from a water depth\nof ~1m. The data presented correspond to the approximate times when subsamples\nwere collected from the towfish seawater outlet for measurements of dissolved\niron and macronutrients (see above).\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.\\t\\t\n \nTemperature: Underway temperature was measured using a conductivity-\ntemperature-depth sensor (SBE 45, SeaBird Electronics).\\t\n \nSalinity: Underway salinity was calculated from in-situ conductivity, as\nmeasured using a conductivity-temperature-depth (CTD) sensor (SBE 45, SeaBird\nElectronics).\\t\n \nFluorescence: Underway chlorophyll fluorescence was measured using a Turner\nAU10 fluorometer.\n \n[The following methodology applies where dataset parameter \"sample_source\" is\n\"CTD\"]\n \nWater column sample collection and in-situ measurements: Water-column samples\nfor analysis of dissolved iron, nitrate plus nitrite, phosphate and ammonium,\nand continuous profiles of temperature, salinity and chlorophyll fluorescence\nwere collected using a trace-metal clean conductivity-temperature-depth sensor\n(SBE 19 plus, SeaBird Electronics) mounted on a custom-built trace-metal clean\ncarousel (SeaBird Electronics) fitted with custom-modified 5-L Teflon-lined\nexternal-closure Niskin-X samplers (General Oceanics), deployed on a Kevlar\nline. Upon recovery, the Niskin-X samplers were transferred into a shipboard\nClass-100 clean laboratory, where seawater was filtered through pre-cleaned\n0.2-\\u00b5m pore AcroPak Supor filter capsules (Pall) into acid-cleaned 125 mL\nlow-density polyethylene bottles (Nalgene) for shore-based dissolved iron\ndeterminations, and 60 mL polypropylene tubes (Falcon) for shipboard nutrient\nanalyses.\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.

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.
