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,.esriCsv,.geoJson
attribute NC_GLOBAL acquisition_description String Sampling

Mussels were collected in the winter (Dec \u2013 Feb) of 2009\u20132010. Sites
were chosen to be approximately evenly distributed along the CA coastline,
with ,80 km geographic separation between each

sampling site. Our main goal here was to sample mussels from a wide geographic
range across the CCS, although for observing finer scale local or regional
variations, a finer-scale sampling strategy would like be required. Typically
5 individual mussels were collected from each site, all between 30\u201340 mm
maximum shell length, which were immediately placed on dry ice until further
preparation. The adductor muscle of each individual was dissected for
analysis. This tissue was selected because isotopic values in muscle tissue
have shown relatively long turnover times; based on past growth data, mussels
of this size would be expected to integrate approximately annual variability
in suspended food source isotopic values for each location sampled.

The dissected adductor tissue was carefully separated from other tissue types,
rinsed with deionized water, refrozen, and then freeze-dried for 48 hrs.
Lipids were removed \u00a0using petroleum ether in a Dionex Accelerated
Solvent Extractor (Bannockburn, IL). Finally, in preparation for CSI-AA,
composite samples were made from a subset of 13 collection sites. For each
location chosen for CSI-AA (based on the bulk d15N record), 160.05 mg of
lyophilized tissue was weighed and combined for each individual mussel (n =
5).

Elemental and Bulk Isotopic Analyses

Stable carbon (d13C) and nitrogen (d15N) isotope ratios were determined via
elemental analyzer isotope ratio mass spectrometry (EA-IRMS) at the University
of California, Santa Cruz, Stable Isotope Laboratory (UCSC-SIL;
[http://emerald.ucsc.edu/~silab/](\\"http://emerald.ucsc.edu/~silab/\\")).
Approximately 1 mg of each dry isolated DOM sample was weighed into tin
capsules (Costec, 5 x 9 mm) for analysis. EA-IRMS analysis was conducted using
a Carlo Erba CHNS-O EA1108-elemental analyzer interfaced via a ConFlo III
device with a ThermoFinnigan Delta Plus XP isotope ratio mass spectrometer
(Thermo Fisher Scientific). \u00a0Standards, EA-IRMS protocols, and correction
routines followed standard UCSC-SIL protocols. Analytical uncertainties of n=3
replicate measurements of isotopic standards ranged from \u00b1 0.05 to
0.1\u2030 for both d13C and d15N. Carbon to nitrogen elemental ratios were
similarly determined by elemental analysis. The presented ratios are atomic
ratios (C/N)a normalized to the mass of C and N, but have been abbreviated as
C/N throughout.

Compound-specific amino acid Isotopic 13C Analyses

Individual AA d13C values were measured as trifluoroacetyl isopropyl ester
(TFA-IP) AA derivatives, after acid hydrolysis. Samples were hydrolyzed by
adding 2.5 mg homogenized composite muscle tissue to 1 ml of 6 N HCl, and
heating for 20 h at 110 deg C under nitrogen. After drying, AA isopropyl
esters were prepared with a 1:5 mixture of AcCl:2-propanol (110 deg C, 60 min)
and then acylated using a 1:3 mixture of di chloro - methane (DCM) and
trifluoroacetic anhydride (TFAA) (100 deg C, 15 min). Derivatized AAs were
dissolved in DCM to a final ratio of approximately 2.5 mg of original tissue
to 250 ul DCM for injection on the gas chromatograph IRMS (GC-IRMS) system.

Isotopic analysis was conducted on a Thermo Trace GC Ultra with inline
oxidation and reduction furnaces, coupled to a ThermoFinnigan Delta Plus XP
IRMS, equipped with a CTC Analytics autosampler.Derivatives (1 ul) were
injected (250 deg C constant temperature) onto an Agilent DB-5 column (50 m
\u00d7 0.32 mm ID \u00d7 0.52 um film thickness), with a He carrier flow rate
of 2 ml min\u22121 (constant flow). Separations were achieved with a 4-ramp
oven program: 52 deg C, 2 min hold; ramp 1 = 15 deg C min\u22121 to 75 deg C,
hold for 2 min; ramp 2 = 4 deg C min\u22121 to 185 deg C, hold for 2 min; ramp
3 = 4 deg C min\u22121 to 200 deg C; ramp 4 = 30 deg C min\u22121 to 240 deg
C, hold for 5 min.

This method allowed for d13C determination of the following AAs in mussel
tissue: non-essential AAs alanine (Ala), aspartic acid + asparagine (Asp),
glutamic acid + glutamine (Glu), glycine (Gly), proline (Pro), serine (Ser),
and tyrosine Tyr); and essential AAs leucine (Leu), isoleucine (Ile), valine
(Val), phenylalanine (Phe), and threonine (Thr). Acid hydrolysis destroys
tryptophan and cystine, so these were not detected, and it also deaminates\\\
asparagine to aspartic acid, and glutamine to glutamic acid. While the
abbreviations Glx and Asx\\\ are sometimes used to denote the combined Gln+Glu
and Asn+Asp peaks, in order to correspond better with extant CSI-AA
literature, we have elected to simply use Asp and Glu abbreviations, as
defined above.

All samples were analyzed on the GC-IRMS in triplicate, and measured AA d13C
values were corrected for the C added during derivatization, following the
approach of Silfer et al. (1991). Reproducibility for tissue samples was
typically less than <0.3\u2030 (n = 3). The average mean deviation for all
tissue sample replicates was 0.4\u2030.

Compound-specific amino acid Isotopic 15N Analyses

Amino acid d15N values were measured as Trifluoroacetyl isopropyl ester (TFA-
IP) AA derivatives, following protocols described in detail elsewhere (e.g.,.
Briefly, samples were hydrolyzed (6 N HCl, 20 hr at 110uC) under nitrogen, and
TFA derivatives subsequently prepared from free AA using a modified version of
the protocol described by Silfer (Silfer et al. 1991): isopropyl esters were
made with a 1:5 mixture of Acetyl Chloride (AcCl):2-propanol (110uC, 60
minutes), and then acylated using a 1:3 mixture of
Dichloromethane:Trifluroacetyl acetate (DCM:TFAA) (100uC, 15 minutes).
Derivatized AAs were dissolved in DCM to a final ratio of approximately 4 mg
of original tissue to 250 ml DCM. After derivatization, samples were analyzed
by a Varian gaschromatograph coupled to a Finnegan Delta-Plus isotope
ratiomass spectrometer (GC-IRMS). AAs were separated using a 50 m, 0.32 ID
Hewlett Packard Ultra-1 column with 1 mm film thickness. Under our analytical
conditions, d15N values could be reproducibly measured for alanine (Ala),
aspartic acid + asparagine (Asp), glutamic acid + glutamine (Glu), leucine
(Leu), isoleucine (Ile), proline (Pro), valine (Val), glycine (Gly), lysine
(Lys), serine (Ser), phenylalanine (Phe), threonine (Thr), and tyrosine (Tyr)
(Fig. S4). Most AAs were measured with a standard error of ,1.0% (based on n =
4 injections), and the average mean deviations for individual AA d15N
measurements across all tissue sample replicates was 0.5%.

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.
