Title: | Delta 15N values from sediment cores collected on the Guaymas Basin Ridge flanks and the Sonora Margin from R/V El Puma during October 2014 (NCEI Accession 0278197) |
Abstract: | This dataset contains chemical data collected on R/V El Puma during cruise Guaymas_2014 from 2014-10-19 to 2014-10-22. These data include d15N. The instruments used to collect these data include Elemental Analyzer and Isotope-ratio Mass Spectrometer. These data were collected by Ivano Aiello of Moss Landing Marine Laboratories, Ana Christina Ravelo of University of California-Santa Cruz, and Andreas P. Teske of University of North Carolina at Chapel Hill as part of the "Characterizing subseafloor life and environments in the Guaymas Basin (C-DEBI Guaymas Subseafloor Life)" and "RAPID proposal: Site characterization cruise to document the active and extensive subsurface biosphere in the Guaymas Basin (RAPID Guaymas Basin)" projects and "Center for Dark Energy Biosphere Investigations (C-DEBI)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-02-11. The following is the text of the dataset description provided by BCO-DMO: delta 15N values from sediment cores P6, P10, P11, P12, and P13, collected on the Guaymas Basin Ridge flanks and the Sonora Margin Dataset Description: delta 15N values from sediment cores P6, P10, P11, P12, and P13, collected on the Guaymas Basin Ridge flanks and the Sonora Margin. Sediment cores were collected from R/V El Puma, the Pacific Coast research vessel of the Autonomous University of Mexico, leaving Guaymas on October 14, 2014, and heading to Mazatlan on October 27, 2014. |

Supplementary information: | Acquisition Description: All coring operations were performed using a the piston-coring system onboard the R/V El Puma. See http://www.buques.unam.mx for additional information. Bulk sediment δ¹⁵N and elemental ratio data were collected using 20mg samples in Sn capsules; organic δ¹³C and elemental composition data were collected using 2.5mg samples of acidified sediment in Sn capsules. All samples were measured by Dumas combustion performed on a Carlo Erba 1108 elemental analyzer coupled to a ThermoFinnigan Delt Plus XP isotope ratio mass spectrometer (EA-IRMS). An in-house gelatin standard, Acetanilide, and an in-house bulk sediment standard, "Monterey Bay Sediment Standard", were used in all runs. Reproducibility of an in-house matrix-matched sediment standard is |
