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: | Survey biogeochemical data from R/V Atlantis AT32, AT34, AT38, and AT39-06 in the western North Atlantic Ocean (35°N to 57°N; 45°W) in Nov. 2015, May 2016, Sep 2017, Mar/Apr 2018 (NCEI Accession 0278182) |
| Abstract: | This dataset contains biological, chemical, optical, and physical data collected on R/V Atlantis during cruises AT32, AT34, AT38, and AT39-06 in the North Atlantic Ocean from 2015-11-12 to 2018-04-05. These data include Oxygen in volts, Total Dissolved Nitrogen, bacterial abundance, beam attenuation, conductivity, density, depth nominal, dissolved Oxygen, dissolved organic Carbon, fluorescence, leucine incorporation rate, salinity calculated from CTD primary sensors, sound velocity, total organic Carbon, turbidity, water pressure, and water temperature. The instruments used to collect these data include Centrifuge, Flow Cytometer, Fluorescence Microscope, GO-FLO Bottle, High Performance Liquid Chromatograph, Liquid Scintillation Counter, Niskin bottle, and Shimadzu TOC-V Analyzer. These data were collected by Craig Carlson of University of California-Santa Barbara as part of the "Tracking the temporal and spatial variability of dissolved organic matter, its diagenetic state and bioavailability during various bloom states in the North Atlantic (DOM_SeasonalDynamics)" project and "North Atlantic Aerosols and Marine Ecosystems Study (NAAMES)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-09-21. The following is the text of the dataset description provided by BCO-DMO: Biogeochemical data from cruises AT32, AT34, AT38, AT39-06 Dataset Description: This dataset includes analyses from Niskin bottle samples collected on R/V Atlantis cruises AT32, AT34, AT38 and AT39-6 as part of the NASA NAAMES campaign (2015-2018). Reported are survey biogeochemical including dissolved organic carbon, dissolved organic nitrogen, total dissolved amino acids. |

| Supplementary information: | Acquisition Description: Samples were collected on RV/Atlantis cruises in the North Atlantic between November 2015 and April 2018. Bacterial abundance was determined by flow cytometry on AT32 and by direct microscope counts for the rest of the cruises (AT34, AT38, AT39-6). Amino acid analysis was conducted for cruises AT34, AT38, and AT39-06. Dissolved organic carbon DOC) and total dissolved nitrogen (TDN) : See Supplemental Files.
