attribute NC_GLOBAL acquisition_description String Sampling Methodology: Three species of tuna, yellowfin (Ta.; Thunnus\nalbacares), skipjack (Kp.; Katsuwonus pelamis), and bigeye (To.; Thunnus\nobesus) tunas, were sampled year-round during 2003-2005 by observers of the\nInter-American Tropical Tuna Commission onboard purse-seine fishing vessels.\nSamples of dorsal white muscle were taken from each fish adjacent to the\nsecond dorsal fin. Fish of uniform size were used for analysis: skipjack tuna\n450-550 mm, yellowfin tuna 500-700 mm, and bigeye tuna 450-550 mm. All samples\nwere stored frozen until further processing in the laboratory.\n \nAnalytical Methodology: Methods are described in Hetherington et al. (2016).\nBriefly: Isotopic analysis of bulk muscle tissue of the tunas was performed at\nthe University of Hawaii\\u2019s Isotope Biogeochemistry Laboratory. Stable\nisotope values of nitrogen were determined using an on-line carbon-nitrogen\nanalyzer coupled with an isotope ratio mass spectrometer (FinniganConFlo II\n/Delta-Plus). Isotope values are reported in conventional delta-notation\nrelative to the international standards, atmospheric N2 and V-PDB, for N and\nC, respectively. Mean accuracy of all stable isotopic analyses was <\n+/-\\u00a00.1 \\u2030 (1 sd) based on triplicate analysis of in-house reference\nmaterials (glycine standard and tuna muscle) with known \\u03b415N values.

attribute NC_GLOBAL instruments_2_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)\nEvidence 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.\nThis 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.
