attribute NC_GLOBAL acquisition_description String Sampling Methodology:\\u00a0Zooplankton, small mesopelagic fishes, and squids\nwere collected from July 28 to December 8, 2006 during the National Oceanic\nand Atmospheric Administration\\u2019s (NOAA's) Stenella Abundance Research\n(STAR) surveys (Gerrodette et al. 2008). We defined our study area to include\na subset of sample locations from the STAR surveys based on the presence of\nboth east-west and north-south productivity gradients across the region, with\ngreater surface chlorophyll a concentrations at the eastern end of the study\narea and along the equator, according to published oceanographic data.\nZooplankton samples were collected with a cylindrical-conical bongo net (333\num mesh), fished to 200 m approximately two hours after sunset, and the\nsamples were frozen within one hour of collection. Specimens of euphausiid\ncrustaceans, Euphausia distinguenda (Ed) and E. tenera (Et) were sorted from\nthe thawed zooplankton samples in the laboratory. Specimens of mesopelagic\nmyctophid fishes Myctophum nitidulum (Mn) and Symbolophorus reversus (Sr) were\ncollected by dipnet at night. Specimens of the squids Dosidicus gigas (Dg) and\nSthenoteuthis oualaniensis (So) also were collected at night, using handlines\nand jigs. (See Olson et al. 2010, Philbrick et al. 2001 for detailed methods).\n \nAnalytical Methodology:\\u00a0Methods are described in Hetherington et al.\n(2016). Briefly: Isotopic analysis of bulk muscle tissue or whole animals was\nperformed at the University of Hawaii\\u2019s Isotope Biogeochemistry\nLaboratory. Stable isotope values of nitrogen were determined using an on-line\ncarbon-nitrogen analyzer coupled with an isotope ratio mass spectrometer\n(FinniganConFlo II/Delta-Plus). Isotope values are reported in conventional\ndelta-notation relative to the international standards atmospheric N2 and\nV-PDB, for N and C, respectively. Mean accuracy of all stable isotopic\nanalyses was < +/-\\u00a00.1 \\u2030 (1 sd) based on triplicate analysis of in-\nhouse reference materials (glycine standard and tuna muscle) with known\n\\u03b415N values.

attribute NC_GLOBAL instruments_0_dataset_instrument_nid String 675270
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 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.
