attribute NC_GLOBAL acquisition_description String Culturing\n \nThe marine diatom Thalassiosira weiss\\ufb02ogii Grunow (strain CCMP 1010) was\ncultured in sterile filtered natural North Sea water (Schleswig-Holstein,\nGermany) or Baltic Sea water (Schleswig-Holstein, Germany). The medium was\nenriched with f/4 concentrations of macro- and micronutrients (nitrate,\nphosphate, silicic acid, trace metal mixture, vitamin mixture (Guillard and\nRyther, 1962). All experiments were performed in sterile 2.1 L Schott Duran\nglass bottles. These bottles were made of borosilicate glass (filters UV\nradiation <310 nm) except for the quartz glass bottles (pure silica without UV\nradiation filter) used in the UV experiment. The cultures were either\nincubated in climate chambers with 400 \\u2013700 nm radiation or 10 cm below\nwater level at low tide in Kiel Fjord in May 2011. Water temperature and light\nirradiance data were obtained from the weather station maintained by the\nGEOMAR institute in Kiel, Germany. Growth conditions for the various\ntreatments, i.e. salinity, pH, temperature and irradiance are given in Table\n1. pH values (reported on free scale) were measured \\u00a0with separate glass\nand reference electrodes (Metrohm) and calculated with equation 3 from DOE\n2007 chapter 6b (Dickson et al., 2007) as described in (Bach et al., 2012).\nCultures were inoculated with densities of 20 cells ml-1. \\u00a0Cell densities\nand equivalent spherical diameters were determined with a Coulter Counter\n(Beckman Coulter) at the beginning and the end of the experiment,\nrespectively. When incubations ended, cells were filtered on 47 mm diameter, 5\num mesh size Nucleopore Track-Etch Membrane filters (Whatman) and frozen at\n-18 deg C immediately after filtration.\n \nSediment sampling\n \nSediment samples were retrieved from a 14.97 m core, station M772-003-2,\ncollected November 26, 2008 by the Meteor cruise M77 at 271 m water depth\nwithin the main upwelling area off Peru (15 deg 06.21\\u00b4S, 75 deg\n41.28\\u00b4W). The Peruvian ocean margin is characterized by a high particle\nflux and a well-defined oxygen minimum zone. At the time of sampling, the O2\nconcentration at the seafloor was measured to 1.1 uM, the salinity to 34.9 psu\nand the temperature to 12.2 \\u00a0deg C.\n \nPrior to analysis, sediment samples were pre-treated with an acid-alkali-acid\ncleaning with HCl and NaOH (Grootes et al., 2004).) \\u00a0 \\u00a0 \\u00a0\n\\u00a0\n \nAnalyses\n \nBoth diatom and sediment samples were freeze dried prior to isotopic analysis.\nTo prepare aliquots for derivatization of amino acids, we used 3-4 mg of\ndiatoms and 100-150 mg of sediments. The samples were transferred to Pyrex\nculture tubes (13 x 100 mm), flushed with N2 gas, sealed, and hydrolysed in 1\nml 6N HCl at 110 \\u00a0deg C for 20 h. After hydrolysis, lipophilic compounds\nwere removed by vortexing with 2 ml n-hexane/DCM (6:5, v/v) for 30 sec. The\naqueous phase was subsequently transferred through disposable glass pipettes\nlined with glass wool into 4 ml dram vials. Samples were evaporated to dryness\nunder a stream of N2 gas for 30 min at 110 deg C before being stored at 18 deg\nC until required for analysis. The derivatisation procedure was modified from\nCorr et al. (2007) as described by Larsen et al. (2013). In short, the dried\nsamples were methylated with acidified methanol and subsequently acetylated\nwith a mixture of acetic anhydride, triethylamine, and acetone, forming\nN-acetyl methyl ester derivatives. As a precautionary measure to reduce the\noxidation of amino acids, we flushed and sealed reaction vials with N2 gas\nprior to methylation and acetylation. Another modification from Corr et al.\n(2007) was that icebaths were substituted with solid aluminum blocks at room\ntemperature. We used known d13C values of pure amino acids prepared and\nanalyzed under the same conditions as the samples to calculate correction\nfactors specific to each amino acid to account for carbon addition and\nfractionation during derivatization. The derivatised AAs were dissolved in 250\nul ethyl acetate and stored at 18 deg C until required for analysis.\n \nAmino acid d13C values were obtained from Leibniz-Laboratory for Radiometric\nDating and Stable Isotope Research in Kiel. We injected the AA derivatives\ninto a PTV injector held at 250 deg C for 4 min. before GC separation on an\nAgilent 6890N GC. Diatom samples were separated on an Rtx-200 column (60m x\n0.32mm x 0.25um, Fig. S1) and sediment samples on a Thermo Trace GOLD TG-200MS\nGC column (60m x 0.32mm x 0.25um). For both GC columns, the oven temperature\nof the GC was started at 50 deg C and heated at 15 deg C min-1 to 140 deg C,\nfollowed by 3 deg C min-1 to 152 deg C and held for 4 min, then 10 deg C min-1\nto 245 deg C and held for 10 min, and finally 5 deg C min-1 to 290 deg C and\nheld for 5 min. The GC was interfaced with a MAT 253 isotope ratio mass\nspectrometer (IRMS) via a GC-III combustion (C) interface (Thermo-Finnigan\nCorporation). We obtained consistently good chromatography for alanine (Ala),\nvaline (Val), leucine (Leu), isoleucine (Ile), asparagine/aspartate (Asx),\nthreonine (Thr), methionine (Met), glutamine/glutamate (Glx), phenylalanine\n(Phe), tyrosine (Tyr), lysine (Lys), and arginine (Arg) with the exception\nthat Asx and Thr partially coeluted with the Rtx-200 column. Serine (Ser) and\nproline (Pro) coeluted on both columns. The average reproducibility for the\nnorleucine internal standard was \\u00b1 0.4\\u2030 (n = 3 for each sample), and\nthe reproducibility of amino acid standards ranged from \\u00b1 0.1\\u2030 for\nPhe to \\u00b1 0.6\\u2030 for Thr (n = 3).\n \nAmino acid composition of the diatom samples was determined with the\nderivative samples used for d13CAA analysis. The amino acids were separated on\nan Rxi-35SIL MS column (30m x 0.32mm x 0.25um) with an Agilent 6890 N GC with\na flame ionization detector. With this column we obtained good chromatography\nfor Ala, Asx, Glx, Gly, Ser, Tyr, Arg, Ile, Leu, Lys, Met, Phe, Thr, and Val.\nFor quantification, we used internal references consisting of pure amino acids\n(Alfa Aesar, Karlsruhe, Germany). The composition of the amino acids are shown\nin Table 3 according to the following biosynthetic families: \\u00a0Pyruvate\n(Ala, Leu, Val), Oxaloacetate (Asx, Ile, Lys, Met, Thr), \\u03b1-ketoglutarate\n(Arg, Glx), 3-phosphoglycerate (Gly, Ser), and Shikimate (Phe, Tyr).\n \nBulk 13C, %C, 15N and %N values of the diatom samples were determined at the\nUC Davis Stable Isotope Facility using a PDZ Europa ANCA-GSL elemental\nanalyzer interfaced to a PDZ Europa 20-20 isotope ratio mass spectrometer\n(Sercon Ltd., Cheshire, UK). The dry weight of the samples ranged between 1.5\nand 2.5 mg. During analysis, samples were interspersed with several replicates\nof at least three different laboratory standards. These laboratory standards,\nwhich were selected to be compositionally similar to the samples being\nanalyzed, had previously calibrated against NIST Standard Reference Materials\n(IAEA-N1, IAEA-N2, IAEA-N3, USGS-40, and USGS-41). A sample\\u2019s preliminary\nisotope ratio was measured relative to reference gases analyzed with each\nsample. These preliminary values were finalized by correcting the values for\nthe entire batch based on the known values of the included laboratory\nstandards. The long term standard deviation is 0.2\\u2030 for 13C and 0.3\\u2030\nfor 15N.

attribute NC_GLOBAL projects_0_acronym String Amino Acid Sediment 15N
attribute NC_GLOBAL projects_0_description String The bioavailability of nutrients plays a crucial role in oceanic biological productivity, the carbon cycle, and climate change. The global ocean inventory of nitrogen (N) is determined by the balance of N-fixation (sources) and denitrification (sinks). In this three-year project, a researcher from the University of California, Santa Cruz, will focus on developing compound-specific N isotope (d15N) analysis of amino acids as a new tool for understanding N source and transformation of organic matter in paleo-reservoirs. The offsets in the isotopic ratios of individual amino acid groups may yield information about trophic transfer, heterotrophic microbial reworking, and autotrophic versus heterotrophic sources. By measuring and comparing the bulk and amino acid d15N in size-fractioned samples from plankton tows, sediments traps, and multi-cores in oxic and suboxic depositional environments, the researcher will: (1) Provide a proxy of the d15N of average exported photoautotrophic organic matter; and (2) Provide a new level of detail into sedimentary organic N degradation and preservation.\nBroader impacts:\nThis project will improve understanding of the fundamental underpinnings and behaviors of d15N amino acid patterns and how they behave in contrasting sedimentary environments, while also developing a potential paleoceanographic proxy. Funding will support a graduate student and undergraduate research at the institution. The researcher will also conduct community outreach in the form of a workshop/tutorial on the proxy development.
