The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv
attribute NC_GLOBAL acquisition_description String Culturing

The marine diatom Thalassiosira weiss\ufb02ogii Grunow (strain CCMP 1010) was
cultured in sterile filtered natural North Sea water (Schleswig-Holstein,
Germany) or Baltic Sea water (Schleswig-Holstein, Germany). The medium was
enriched with f/4 concentrations of macro- and micronutrients (nitrate,
phosphate, silicic acid, trace metal mixture, vitamin mixture (Guillard and
Ryther, 1962). All experiments were performed in sterile 2.1 L Schott Duran
glass bottles. These bottles were made of borosilicate glass (filters UV
radiation <310 nm) except for the quartz glass bottles (pure silica without UV
radiation filter) used in the UV experiment. The cultures were either
incubated in climate chambers with 400 \u2013700 nm radiation or 10 cm below
water level at low tide in Kiel Fjord in May 2011. Water temperature and light
irradiance data were obtained from the weather station maintained by the
GEOMAR institute in Kiel, Germany. Growth conditions for the various
treatments, i.e. salinity, pH, temperature, and irradiance are given in Table
1. pH values (reported on free scale) were measured \u00a0with separate glass
and reference electrodes (Metrohm) and calculated with equation 3 from DOE
2007 chapter 6b (Dickson et al., 2007) as described in (Bach et al., 2012).
Cultures were inoculated with densities of 20 cells ml-1. \u00a0Cell densities
and equivalent spherical diameters were determined with a Coulter Counter
(Beckman Coulter) at the beginning and the end of the experiment,
respectively. When incubations ended, cells were filtered on 47 mm diameter, 5
um mesh size Nucleopore Track-Etch Membrane filters (Whatman) and frozen at
-18 deg C immediately after filtration.

Sediment sampling

Sediment samples were retrieved from a 14.97 m core, station M772-003-2,
collected November 26, 2008 by the Meteor cruise M77 at 271 m water depth
within the main upwelling area off Peru (15 deg 06.21\u00b4S, 75 deg
41.28\u00b4W). The Peruvian ocean margin is characterized by a high particle
flux and a well-defined oxygen minimum zone. At the time of sampling, the O2
concentration at the seafloor was measured to 1.1 uM, the salinity to 34.9 psu
and the temperature to 12.2 \u00a0deg C.

Prior to analysis, sediment samples were pre-treated with an acid-alkali-acid
cleaning with HCl and NaOH (Grootes et al., 2004).) \u00a0 \u00a0 \u00a0
\u00a0

Analyses

Both diatom and sediment samples were freeze dried prior to isotopic analysis.
To prepare aliquots for derivatization of amino acids, we used 3-4 mg of
diatoms and 100-150 mg of sediments. The samples were transferred to Pyrex
culture tubes (13 x 100 mm), flushed with N2 gas, sealed, and hydrolysed in 1
ml 6N HCl at 110 \u00a0deg C for 20 h. After hydrolysis, lipophilic compounds
were removed by vortexing with 2 ml n-hexane/DCM (6:5, v/v) for 30 sec. The
aqueous phase was subsequently transferred through disposable glass pipettes
lined with glass wool into 4 ml dram vials. Samples were evaporated to dryness
under a stream of N2 gas for 30 min at 110 deg C before being stored at 18 deg
C until required for analysis. The derivatisation procedure was modified from
Corr et al. (2007) as described by Larsen et al. (2013). In short, the dried
samples were methylated with acidified methanol and subsequently acetylated
with a mixture of acetic anhydride, triethylamine, and acetone, forming
N-acetyl methyl ester derivatives. As a precautionary measure to reduce the
oxidation of amino acids, we flushed and sealed reaction vials with N2 gas
prior to methylation and acetylation. Another modification from Corr et al.
(2007) was that icebaths were substituted with solid aluminum blocks at room
temperature. We used known d13C values of pure amino acids prepared and
analyzed under the same conditions as the samples to calculate correction
factors specific to each amino acid to account for carbon addition and
fractionation during derivatization. The derivatised AAs were dissolved in 250
ul ethyl acetate and stored at 18 deg C until required for analysis.

Amino acid d13C values were obtained from Leibniz-Laboratory for Radiometric
Dating and Stable Isotope Research in Kiel. We injected the AA derivatives
into a PTV injector held at 250 deg C for 4 min. before GC separation on an
Agilent 6890N GC. Diatom samples were separated on an Rtx-200 column (60m x
0.32mm x 0.25um, Fig. S1) and sediment samples on a Thermo Trace GOLD TG-200MS
GC column (60m x 0.32mm x 0.25um). For both GC columns, the oven temperature
of the GC was started at 50 deg C and heated at 15 deg C min-1 to 140 deg C,
followed by 3 deg C min-1 to 152 deg C and held for 4 min, then 10 deg C min-1
to 245 deg C and held for 10 min, and finally 5 deg C min-1 to 290 deg C and
held for 5 min. The GC was interfaced with a MAT 253 isotope ratio mass
spectrometer (IRMS) via a GC-III combustion (C) interface (Thermo-Finnigan
Corporation). We obtained consistently good chromatography for alanine (Ala),
valine (Val), leucine (Leu), isoleucine (Ile), asparagine/aspartate (Asx),
threonine (Thr), methionine (Met), glutamine/glutamate (Glx), phenylalanine
(Phe), tyrosine (Tyr), lysine (Lys), and arginine (Arg) with the exception
that Asx and Thr partially coeluted with the Rtx-200 column. Serine (Ser) and
proline (Pro) coeluted on both columns. The average reproducibility for the
norleucine internal standard was \u00b1 0.4\u2030 (n = 3 for each sample), and
the reproducibility of amino acid standards ranged from \u00b1 0.1\u2030 for
Phe to \u00b1 0.6\u2030 for Thr (n = 3).

Amino acid composition of the diatom samples was determined with the
derivative samples used for d13CAA analysis. The amino acids were separated on
an Rxi-35SIL MS column (30m x 0.32mm x 0.25um) with an Agilent 6890 N GC with
a flame ionization detector. With this column we obtained good chromatography
for Ala, Asx, Glx, Gly, Ser, Tyr, Arg, Ile, Leu, Lys, Met, Phe, Thr, and Val.
For quantification, we used internal references consisting of pure amino acids
(Alfa Aesar, Karlsruhe, Germany). The composition of the amino acids are shown
in Table 3 according to the following biosynthetic families: \u00a0Pyruvate
(Ala, Leu, Val), Oxaloacetate (Asx, Ile, Lys, Met, Thr), \u03b1-ketoglutarate
(Arg, Glx), 3-phosphoglycerate (Gly, Ser), and Shikimate (Phe, Tyr).

Bulk 13C, %C, 15N and %N values of the diatom samples were determined at the
UC Davis Stable Isotope Facility using a PDZ Europa ANCA-GSL elemental
analyzer interfaced to a PDZ Europa 20-20 isotope ratio mass spectrometer
(Sercon Ltd., Cheshire, UK). The dry weight of the samples ranged between 1.5
and 2.5 mg. During analysis, samples were interspersed with several replicates
of at least three different laboratory standards. These laboratory standards,
which were selected to be compositionally similar to the samples being
analyzed, had previously calibrated against NIST Standard Reference Materials
(IAEA-N1, IAEA-N2, IAEA-N3, USGS-40, and USGS-41). A sample\u2019s preliminary
isotope ratio was measured relative to reference gases analyzed with each
sample. These preliminary values were finalized by correcting the values for
the entire batch based on the known values of the included laboratory
standards. The long term standard deviation is 0.2\u2030 for 13C and 0.3\u2030
for 15N.

attribute NC_GLOBAL project String The Use of Nitrogen Isotopes of Amino Acids To Understand Marine Sedimentary 15N Records
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.
Broader impacts:
This 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.
