attribute NC_GLOBAL acquisition_description String Sampling Methodology:\u00a0Zooplankton, small mesopelagic fishes, and squids
were collected from July 28 to December 8, 2006 during the National Oceanic
and Atmospheric Administration\u2019s (NOAA's) Stenella Abundance Research
(STAR) surveys (Gerrodette et al. 2008). We defined our study area to include
a subset of sample locations from the STAR surveys based on the presence of
both east-west and north-south productivity gradients across the region, with
greater surface chlorophyll a concentrations at the eastern end of the study
area and along the equator, according to published oceanographic data.
Zooplankton samples were collected with a cylindrical-conical bongo net (333
um mesh), fished to 200 m approximately two hours after sunset, and the
samples were frozen within one hour of collection. Specimens of euphausiid
crustaceans, Euphausia distinguenda (Ed) and E. tenera (Et) were sorted from
the thawed zooplankton samples in the laboratory. Specimens of mesopelagic
myctophid fishes Myctophum nitidulum (Mn) and Symbolophorus reversus (Sr) were
collected by dipnet at night. Specimens of the squids Dosidicus gigas (Dg) and
Sthenoteuthis oualaniensis (So) also were collected at night, using handlines
and jigs. (See Olson et al. 2010, Philbrick et al. 2001 for detailed methods).

Three species of tuna, yellowfin (Ta.; Thunnus albacares), skipjack (Kp.;
Katsuwonus pelamis), and bigeye (To.; Thunnus obesus) tunas, were sampled
year-round during 2003-2005 by observers of the Inter-American Tropical Tuna
Commission onboard purse-seine fishing vessels. Samples of dorsal white muscle
were taken from each fish adjacent to the second dorsal fin. Fish of uniform
size were used for analysis: skipjack tuna 450-550 mm, yellowfin tuna 500-700
mm, and bigeye tuna 450-550 mm. All samples were stored frozen until further
processing in the laboratory.

Analytical Methodology:\u00a0 Methods are described in Hetherington et al.
(2016). Briefly: Amino acid (AA) compound-specific isotope analysis (AA-CSIA)
was conducted on a subset of 48 of the samples used for isotopic analysis of
bulk muscle tissue or whole animals. The basis for sample selection was to
represent the range of variability in bulk \u03b415N values and the range of
sample locations along the transect. The d15N values of individual AAs were
measured using an isotope ratio mass spectrometer (IRMS) (Delta PlusXP, Delta
V Plus or MAT 253) interfaced with a gas chromatograph (Trace GC) through a
GC-C III combustion furnace (980 degrees C), reduction furnace (650 degrees
C), and liquid-N cold trap. All samples were analyzed in triplicate and the
measured AA-d15N values were normalized to known d15N values of two coinjected
internal reference compounds (norleucine and aminoadipic acid with d15N
reference values of 19.06 \u2030 and -5.8 \u2030, respectively).

attribute NC_GLOBAL instruments_0_description String A Bongo Net consists of paired plankton nets, typically with a 60 cm diameter mouth opening and varying mesh sizes, 10 to 1000 micron. The Bongo Frame was designed by the National Marine Fisheries Service for use in the MARMAP program. It consists of two cylindrical collars connected with a yoke so that replicate samples are collected at the same time. Variations in models are designed for either vertical hauls (OI-2500 = NMFS Pairovet-Style, MARMAP Bongo, CalVET) or both oblique and vertical hauls (Aquatic Research). The OI-1200 has an opening and closing mechanism that allows discrete "known-depth" sampling. This model is large enough to filter water at the rate of 47.5 m3/minute when towing at a speed of two knots. More information: Ocean Instruments, Aquatic Research, Sea-Gear

attribute NC_GLOBAL instruments_3_dataset_instrument_nid String 679633
attribute NC_GLOBAL instruments_3_description String A purse seine is a large wall of netting deployed in a circle around an entire school of fish. The seine has floats along the top line with a lead line of chain along the bottom. Once a school of fish is located, a skiff pulls the seine into the water as the vessel encircles the school with the net. A cable running along the bottom is then pulled in, "pursing" the net closed on the bottom, preventing fish from escaping by swimming downward. The catch is harvested by bringing the net alongside the vessel and brailing the fish aboard.

attribute NC_GLOBAL project String CAMEO_Trophic_Position
attribute NC_GLOBAL projects_0_acronym String CAMEO_Trophic_Position
attribute NC_GLOBAL projects_0_description String (From NSF Award Abstract)
Evidence increasingly demonstrates that selective removal of marine life can induce restructuring of marine food webs. Trophic structure is the central component of mass balance models, widely used tools to evaluate fisheries in an ecosystem context. Food web structure is commonly determined by stomach contents or by bulk tissue stable isotope analyses, both of which are limited in terms of resolution and versatility. The investigators will refine a tool, Amino Acid Compound-Specific Isotopic Analyses (AA-CSIA), which can be broadly applicable for quantifying the time-integrated trophic position (TP) of consumers. Differences in source and trophic nitrogen isotopic composition for specific amino acids will provide an unambiguous and integrated measure of fractional trophic TP across multiple phyla, regardless of an animal's physiological condition or of the biogeochemical cycling at the base of the food web. AA-CSIA will allow testing of the efficacy of trophic position estimates derived from ecosystem-based models and promote the evolution of these models into decision-support tools.
This project has three goals: 1. To validate the application of AA-CSIA across multiple marine phyla under differing physiological conditions. 2. To compare the application of AA-CSIA across systems with contrasting biogeochemical cycling regimes. 3. To develop the use of AA-CSIA TP estimates for validating trophic models of exploited ecosystems. The investigators will test and refine the approach using a combination of laboratory feeding experiments and field studies across regions with differing biogeochemical cycling regimes. They will determine the applicability of the AA-CSIA approach in a variety of marine organisms assessed in controlled studies. Subsequently, ecosystem components will be sampled from the eastern tropical Pacific, coastal California and the subtropical Pacific gyre. They will also test the effects of sample preservation on the isotopic composition of individual AA to determine whether the approach can be used on archived samples. This tool will allow testing of the efficacy of ecosystem-based models currently used to gain insight into the ecological effects of fisheries removals and improve the reliability of future models required to manage marine resources. In addition to the goal of developing AA-CSIA for use as a TP indicator, the information obtained through this project will provide important species-specific biological data on the feeding behavior of marine organisms that could have implications for their resilience to anthropogenic pressures and climate change.
