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: | Nitrate, nitrite, and nitrous oxide isotope measurements from the Eastern Tropical South Pacific ocean collected on RVIB Nathaniel B. Palmer cruise NBP1305 from June to July 2013 (NCEI Accession 0278098) |
| Abstract: | This dataset contains chemical and physical data collected on RVIB Nathaniel B. Palmer during cruise NBP1305 in the South Pacific Ocean from 2013-06-27 to 2013-07-19. These data include Nitrous Oxide, O2 saturation, d15N, d18O_NO3, dN15_NO3, depth, dissolved Oxygen, salinity calculated from CTD primary sensors, sigma-theta potential density, water pressure, and water temperature. The instruments used to collect these data include Isotope-ratio Mass Spectrometer. These data were collected by Dr Karen L. Casciotti of Stanford University as part of the "Biogeochemistry of nitrous oxide cycling in the eastern tropical South Pacific (N2O Cycling)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-03-15. The following is the text of the dataset description provided by BCO-DMO: Nitrate, nitrite, and nitrous oxide isotope measurements from the Eastern Tropical South Pacific ocean (NBP13-05) Dataset Description: Nitrate, nitrite, and nitrous oxide isotope measurements from the Eastern Tropical South Pacific ocean (NBP13-05). The data in this dataset were published in Peters et al. (2018) and Casciotti et al. (2018). |

| Supplementary information: | Acquisition Description: Samples were collected from a standard Niskin bottle rosette. Nitrate isotope analyses were conducted by denitrifier method (Sigman et al., 2001; Casciotti et al., 2002) with updates (McIlviin and Casciotti, 2011). Nitrite was removed from samples containing more than 0.1 uM nitrite, using sulfuric acid (Granger and Sigman, 2009). Standards include USGS32, USGS34, and USGS35. Nitrite isotope analyses were conducted by azide method (McIlvin and Altabet, 2005). Standards include N23, N7373, and N10219. Nitrous oxide isotope analyses were conducted as described in McIlvin and Casciotti, 2010. N2O isotope measurements were calibrated against a laboratory N2O working gas. The water mass analysis for the oxygen deficient zone waters was conducted as described in Peters et al., 2018, Deep Sea Research II, Estimating fixed nitrogen loss and associated isotope effects using concentration and isotope measurements of NO3-, NO2-, and N2 from the Eastern Tropical South Pacific oxygen deficient zone. |
