The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Bulk raw isotopic data from tissue samples from non-tuna species collected in the eastern tropical Pacific Ocean onboard two NOAA research ships, NOAA Ship David Starr Jordan and McArthur II, (cruises SWFSC1630 and SWFSC1631) in 2006 (NCEI Accession 0278289) |
| Abstract: | This dataset contains biological, chemical, and survey - biological data collected on NOAA Ship David Starr Jordan and NOAA Ship McArthur II during cruises SWFSC1630 and SWFSC1631 from 2006-08-11 to 2006-10-28. These data include d13C, d15N measured in biota, and species. The instruments used to collect these data include Bongo Net, Elemental Analyzer, Hand Net, Handline and Jig, and Isotope-ratio Mass Spectrometer. These data were collected by Robert Olson of Inter-American Tropical Tuna Commission and Brian N. Popp and Jeffrey C. Drazen of University of Hawaii as part of the "CAMEO 2009 - A novel tool for validating trophic position estimates in ecosystem-based fisheries models (CAMEO_Trophic_Position)" project and "Comparative Analysis of Marine Ecosystem Organization (CAMEO)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-01-21. The following is the text of the dataset description provided by BCO-DMO: Bulk raw isotopic data from tissue samples from non-tuna species collected in the eastern tropical Pacific Ocean onboard two NOAA research ships Dataset Description: Bulk raw isotopic data from tissue samples from two species of ommastrephid cephalopods (squids), two species of mesopelagic myctophid fishes, and two species of euphausiid crustaceans collected in the eastern tropical Pacific Ocean onboard two NOAA research ships. |

| Supplementary information: | Acquisition Description: Sampling Methodology: Zooplankton, small mesopelagic fishes, and squids were collected from July 28 to December 8, 2006 during the National Oceanic and Atmospheric Administration’s (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). Analytical Methodology: Methods References: Hetherington et al. (2016). Briefly: Isotopic analysis of bulk muscle tissue or whole animals was performed at the University of Hawaii’s Isotope Biogeochemistry Laboratory. Stable isotope values of nitrogen were determined using an on-line carbon-nitrogen analyzer coupled with an isotope ratio mass spectrometer (FinniganConFlo II/Delta-Plus). Isotope values are reported in conventional delta-notation relative to the international standards atmospheric N 2 and V-PDB, for N and C, respectively. Mean accuracy of all stable isotopic analyses was |
