attribute NC_GLOBAL acquisition_description String Micronekton were collected using a 10 m2 multiple opening-closing net and
environmental sensing system (MOCNESS) at Station ALOHA (22.75\u02daN,
158\u02daW) in March and August of 2011 and in February and September of 2014
with a few samples from other locations around Oahu in 2011 (Choy et al 2015).
Micronekton were collected over five depth zones between the surface and 1500
m: 0 \u2013 100 m, 100 \u2013 500 m, 500 \u2013 700 m, 700 \u2013 1000 m and
1000 \u2013 1500 m. At sea, micronekton were sorted and identified to the most
specific taxonomic level, then measured and photographed. Standard length
measurements were taken for fish, carapace length and total length were taken
for crustaceans and both mantle length and total length were taken for
cephalopods. For most fishes, white muscle tissue was removed and frozen in a
cryovial in liquid nitrogen. Small fishes, crustaceans and gelatinous
organisms were frozen whole or individuals were pooled for sufficient tissue
required for stable isotope analysis. Specimens were transferred to a
\u201180\u02daC freezer until the samples could be prepared for stable isotope
analysis.

Eighty-three samples (individual specimens or small groups of conspecifics)
were selected for stable isotope analysis. Samples selected for stable isotope
analysis represented different combinations of trophic strategies (suspension
feeding, zooplanktivores, micronektonivores), depth guilds (epipelagic,
mesopelagic, bathypelagic) and migrating behaviors based on available
ecological information (e.g., Clarke 1973, Maynard 1982). Each sample was
freeze-dried and ground using a ceramic mortar and pestle. For bulk tissue
carbon and nitrogen isotope analysis approximately 0.5 mg of each sample was
weighed and placed into a tin boat. Carbon and nitrogen isotopic compositions
were determined using an isotope ratio mass spectrometer (DeltaPlusXP) coupled
to an elemental analyzer (Costech Model 4010). Isotopic ratios are given in
\u03b4-notation relative to the international standards VPDB and atmospheric
N2. Accuracy and precision were 0.2\u2030 based on glycine and homogenized
fish tissue reference materials analyzed every ten samples. The isotopic
compositions of the reference materials have been extensively characterized
using NIST certified reference materials in the UH laboratory and verified
independently in other isotope laboratories.

Amino acid-specific stable N isotope composition was determined on
approximately 15 mg (dry weight) of each sample underwent acid hydrolysis and
derivatization yielding trifluoroacetic (TFA) amino acid esters following the
methods of Popp et al. (2007) and Hannides et al. (2009b).; The nitrogen
isotope composition of the trifluoroacetic amino acid esters were determined
using an isotope ratio mass spectrometer (Thermo Scientific Delta V Plus or
Thermo Scientific MAT 253 IRMS) interfaced with a Thermo Finnigan GC-C III.
Samples were injected onto a BPx5 forte capillary column (60m x 0.32 mm x 1.0
\u00b5m film thickness) at an injector temperature of 180\u02daC with a
constant helium flow rate of 1.4 mL/min. The column was initially held at
50\u02daC for two minutes and then increased at a rate of 15\u02daC/min to
120\u02daC. Temperature was then increased at a rate of 4\u02daC/min to
195\u02daC, then to 255\u02daC at a rate of 5\u02daC/min and finally to
300\u02daC at a rate of 15\u02daC/min, holding at the final temperature for
eight minutes. Each sample was analyzed in triplicate and co-injected with the
reference compounds norleucine (Nor) and aminoadipic acid (AAA) of known
isotopic composition. A suite of pure amino acids of known nitrogen isotopic
composition (Ala, Thr, Ile, Pro, Glu, and Phe) was also injected every three
runs as an extra measure of accuracy for the instrument. Reference compounds
Nor and AAA, as well as the suite of amino acids, were used to normalize the
measured isotope values. Standard deviation for all amino acids averaged
\u00b10.4\u2030 (range 0.0-3.1\u2030).

There are currently 8 different sizes of MOCNESS in existence which are designed for capture of different size ranges of zooplankton and micro-nekton Each system is designated according to the size of the net mouth opening and in two cases, the number of nets it carries. The original MOCNESS (Wiebe et al, 1976) was a redesigned and improved version of a system described by Frost and McCrone (1974).(from MOCNESS manual) This designation is used when the specific type of MOCNESS (number and size of nets) was not specified by the contributing investigator.

attribute NC_GLOBAL project String Collaborative Research: Isotopic insights to mercury in marine food webs and how it varies with ocean biogeochemistry
attribute NC_GLOBAL projects_0_acronym String Hg_Biogeochemistry
attribute NC_GLOBAL projects_0_description String Extracted from the NSF award abstract:
Mercury is a pervasive trace element that exists in several states in the marine environment, including monomethylmercury (MMHg), a neurotoxin that bioaccumulates in marine organisms and poses a human health threat. Understanding the fate of mercury in the ocean and resulting impacts on ocean food webs requires understanding the mechanisms controlling the depths at which mercury chemical transformations occur. Preliminary mercury analyses on nine species of marine fish from the North Pacific Ocean indicated that intermediate waters are an important entry point for MMHg into open ocean food webs. To elucidate the process controlling this, researchers will examine mercury dynamics in regions with differing vertical dissolved oxygen profiles, which should influence depths of mercury transformation. Results of the study will aid in a better understanding of the pathways by which mercury enters the marine food chain and can ultimately impact humans.�
Mercury isotopic variations can provide insight into a wide variety of environmental processes. Isotopic compositions of mercury display mass-dependent fractionation (MDF) during most biotic and abiotic chemical reactions and mass-independent fractionation (MIF) during photochemical radical pair reactions. The unusual combination of MDF and MIF can provide information on reaction pathways and the biogeochemical history of mercury. Results from preliminary research provide strong evidence that net MMHg formation occurred below the surface mixed layer in the pycnocline and suggested that MMHg in low oxygen intermediate waters is an important entry point for mercury into open ocean food webs. These findings highlight the critical need to understand how MMHg levels in marine biota will respond to changes in atmospheric mercury emissions, deposition of inorganic mercury to the surface ocean, and hypothesized future expansion of oxygen minimum zones. Using field collections across ecosystems with contrasting biogeochemistry and mercury isotope fractionation experiments researchers will fill key knowledge gaps in mercury biogeochemistry. Results of the proposed research will enable scientists to assess the biogeochemical controls on where in the water column mercury methylation and demethylation likely occur.
