attribute	NC_GLOBAL	acquisition_description	String	Sampling Plankton samples were obtained during Leg 8 of the Malaspina-2010 expedition on R/V Sarmiento de Gamboa (January-March 2011), on a transect predominantly along 24\u00baN, between the Canary Island and Florida. Briefly, plankton samples were collected by vertical tows of a microplankton net (40 \u00b5m mesh size) and a mesoplankton net (200 \u00b5m mesh size) through the upper 200 m of the water column. Sampling was between 10:00 and 16:00 h GMT. Plankton was separated into five size fractions (40\u2013200, 200\u2013500, 500\u20131000, 1000\u20132000 and 2000 \u00b5m) by gentle filtration of the samples by a graded series of nylon sieves (2000, 1000, 500, 200 and 40 \u00b5m). Large gelatinous organisms were removed before filtration. Aliquots for each size fraction were collected on pre-weighed glass-fiber filters, dried (60\u00baC, 48 h) and stored in a desiccator before determination of biomass (dry weight), carbon and nitrogen content and natural abundance of stable carbon and nitrogen isotopes ashore. Nominal values of the individual size of organisms in each size fraction were estimated as the geometric mean of the values defining each size interval and expressed as carbon content (\u00b5g C) in a logarithmic scale Bulk \u03b415N analysis After determination of dry weight, finely ground aliquots of each size fraction were packed in tin capsules for elemental and stable isotope analysis by conversion into CO2 and N2 in an elemental analyzer (Carlo Erba CHNSO 1108) coupled to an isotope-ratio mass-spectrometer (Finnigan Mat Delta Plus). Compound-specific amino acid \u03b415N analysis Samples for CSI-AA were selected to span gradients in 15Nbulk values. We\u00a0chose plankton from four sampling stations in each of the three zones (eastern, central and western regions).\u00a0 Individual samples were then pooled (quantitatively, so that each subsample was represented equally in the final composite) to have enough material in each size fraction for CSI-AA. In total 15 samples in the transect were chosen for CSI-AA. Approximately 1 mg of total dry plankton material was then hydrolyzed for subsequent analysis. The \u03b415N values of individual AAs were measured via GC-IRMS, after 6 N HCl acid hydrolysis and the formation of TFA ester derivatives following previously published methods.\u00a0 Briefly, amino acids were liberated by hydrolysis (6 N HCl, 20 hr at 110uC) under nitrogen, and TFA derivatives subsequently prepared from free AA: 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 2 mg of original dry sample to 250 ml DCM. After derivatization, samples were analyzed by a thermos Trace Ultra gas chromatograph coupled to a Finnegan Delta-Plus isotope ratio mass spectrometer (GC-IRMS). AAs were separated using a 50 m, 0.32 ID Hewlett Packard Ultra-1 column with 1 mm film thickness.\u00a0 AAs were measured based on n = 4 injections, and the average mean deviations for individual AA d15N measurements across all sample replicates was 0.5%. Under these conditions, we determined \u03b415N values for 12 AAs: glutamic acid + glutamine (Glx), aspartic acid + asparagine (Asp), alanine (Ala), Isoleucine (Ile), Leucine (Leu), Proline (Pro), valine (Val), glycine (Gly), serine (Ser), Lysine (Lys), phenylalanine (Phe), and Threonine (Thr). Each AA was run four times on the GC-IRMS..\u00a0 AA values were categorized and presented in 3 groups, based on their relative 15N values changes with trophic transfer: the source AAs (Gly, Ser, Lys, Phe), the trophic AAs (Glx, Asp, Ala, Ile, Leu, Pro and Val), and one \u201cmetabolic\u201d AA (Thr). Trophic position and \u03a3V\u00a0 To calculate CSI-AA based TP of plankton we used the most widely used current equation and TEF value, based on the isotopic offset between Glx and Phe: TP\u00a0 = (\u03b415NGlx \u2013 \u03b415NPhe \u2013 3.4)/7.6 +1 where \u03b415NGlx and \u03b415NPhe are measured values, +3.4\u2030 is the assumed isotopic difference between the Glx and Phe in primary producers, and +7.6\u2030 is the assumed 15N enrichment in Glx relative to Phe with each trophic transfer from food source to consumer (TEF value). The standard errors in the estimation of TP, computed by propagation of analytical error in the individual AA determinations, did not exceed 0.1 TP. The \u03b415N value of total hydrolysable AAs (\u03b415NTHAA) is used as a proxy for total protein \u03b415N value, and was estimated as the molar- weighted average of individual \u03b415N values: \u03b415NTHAA = \u03a3 (\u03b415NAA * mol% AA) where \u03b415NAA is the \u03b415N value of each individual AA measured and mol%AA is the molar percentage contribution of each AA. In our study we used the \u03b415N value of each individual AA and mol%AA were obtained from Lehman (2009). The degradation index \u03a3V is a measure of the relative resynthesis of the original autotrophic AA pool in detritus or different organisms (plankton size fractions, in our case) was for each size individual fraction sample as the mean deviation of \u03b415N of individual trophic amino acid, from their average: \u03a3V\u00a0 = \u03a3 (AAi \u2013 Avg trp) / n Where AAi were individual \u03b415N amino acid values, Avg trp is the average value and n the total number of trophic amino acids.

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.
