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: | Suspended particles from ship’s surface intake samples collected on R/V Kilo Moana cruise KM1910 in June 2019 (NCEI Accession 0278606) |
| Abstract: | This dataset contains chemical and physical data collected on R/V Kilo Moana during cruise KM1910 in the North Pacific Ocean from 2019-06-16 to 2019-06-21. These data include Carbon, d13C, d15N, and particulate organic nitrogen. The instruments used to collect these data include Conductivity Meter, Elemental Analyzer, Gas Chromatograph, and Isotope-ratio Mass Spectrometer. These data were collected by Angelicque E. White of University of Hawaii, Erica Goetze and Sara Ferron of University of Hawaii at Manoa, and Matthew J. Church of University of Montana as part of the "EAGER Collaborative Research: Early career chief scientist training for biological and chemical oceanographers (Chief Sci KM1910)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2021-06-08. The following is the text of the dataset description provided by BCO-DMO: Suspended particles from ship’s surface intake Dataset Description: Surface particulate carbon concentration, nitrogen concentration, and bulk isotope composition (C and N) from underway clean water intake during June 2019 at station ALOHA during cruise KM1910. |

| Supplementary information: | Acquisition Description: Suspended particulates were collected while underway using the ship's clean surface water intake ( ~0 to 5 m ocean depth) in the hydro lab sink aboard RV Kilo Moana. Water was passed through three separate filter holders containing 1) an acid-washed 53um mesh screen pre-filter followed by 2), a combusted (4.5hrs 450 degrees C) 142mm GF/F (Whatman nominal pore size 0.7um) and finally followed by 3), a combusted 142mm GF75 (Advantec nominal pore size 0.3um). Samples were folded (active side in) and stored in clean (combusted) foil at -20 degrees C until subsampled with metal cork borer (subsamples were not acidified so PC and d13C represents total C). Subsamples were oven-dried overnight at 55-60 degrees C then packed in 9x11 tin capsules for analysis on EA IRMS. Six blank (dry) filters were analyzed for background C and N and subtracted from measured PC and PN sample values. EA-IRMS: a Vario ISOTOPE select (Elementar Isoprime) was used to quantify total C, N, and d13C and d15N. Samples are combusted/reduced at high temperature to create gases (CO2 and N2); column chromatography separates the gases; a thermal conductivity detector determines the carbon and nitrogen concentrations, followed by an isotope ratio mass spectrometer for bulk isotope composition. Measurements were calibrated with an in-house aminocaproic acid standard (ACROS) and four USGS standards (#41, #41a, #65, #25). Analytical uncertainty (determined from standards with similar isotope values) was 0.2‰ for delta-15N and 0.1‰ for delta-13C. Known problems Lat and Lon was not recorded at end of sample starting at 11:51 and ending at 15:30 on 190617 |
