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: | Nutrients and pigments from HPLC analysis for fire ash deposition to coastal ocean study, southern California, December 2017 (NCEI Accession 0277746) |
| Abstract: | This dataset contains biological, chemical, optical, and physical data collected on R/V Sally Ride during cruise SR1718 in the North Pacific Ocean from 2017-12-16 to 2017-12-22. These data include 19-prime-butanoyloxyfucoxanthin, 19-prime-hexanoyloxyfucoxanthin, Ammonium, Nitrite, PAR_photons, Silicate, beam attenuation, carotene, chlorophyll b, chlorophyll c total, chlorophyll c2, chlorophyll c3, chlorophyllide a, conductivity, density, depth, diadinoxanthin, diatoxanthin, dissolved Oxygen, divinyl chlorophyll a, divinyl chlorophyll b, fluorescence, fucoxanthin, monovinyl chlorophyll a, monovinyl chlorophyll b, neoxanthin, nitrate plus nitrite, particulate organic Carbon (POC), particulate organic nitrogen, potential temperature, prasinoxanthin, reactive phosphorus (PO4), salinity calculated from CTD primary sensors, sigma-t, violaxanthin, water pressure, water temperature, and zeaxanthin. The instruments used to collect these data include CTD Sea-Bird SBE 911plus and Niskin bottle. These data were collected by David L. Valentine of University of California-Santa Barbara as part of the "RAPID: Biogeochemical effects of fire ash deposition to the coastal ocean, in response to the 2017 Southern California fires (FADCO)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-09-25. The following is the text of the dataset description provided by BCO-DMO: Nutrients and pigments Dataset Description: Nutrients and pigments from HPLC analysis for fire ash deposition to coastal ocean study, southern California, December 2017. |

| Supplementary information: | Acquisition Description: POC: 500 mL seawater was filtered from depths above 100 m. One L seawater was filtered for depths below 100 m. All seawater samples were filtered gently via vacuum ( Nutrients: 40 mL of seawater was directly filtered from the Niskin bottle through a 0.8 µm polycarbonate filter housed in a 47 mm polycarbonate filter holder into a sterile 50 mL conical centrifuge tube. Samples were stored at -20˚C until analysis at the UC Santa Barbara Marine Science Institute Analytical Lab via flow-injection analysis on a QuickChem 8500 Series 2. HPLC: Approximately 2 L seawater was filtered through 25 mm (0.7 µm) Whatman GF/F filters. Filters were folded in half, stored in foil packets, and put immediately in liquid nitrogen, where they were kept through shipment to and until analysis at NASA Goddard Space Flight Center. HPLC pigments were analyzed by Crystal Thomas following Van Heukelem and Thomas (2001): https://oceancolor.gsfc.nasa.gov/fsg/hplc/ Quality flags reflect those used by the World Ocean Circulation Experiment (WOCE): 1: sample taken 2: acceptable measurement 3. questionable measurement 4. bad measurement 5. not reported 9. no sample drawn |
