    "title": "CTD and underwater mass spectrometer data acquired in 2016 aboard the RV\/Endeavor (cruise EN575) in the the subtropical Atlantic using a Triaxus tow vehicle (NCEI Accession 0278171)",
    "description": "This dataset contains biological, chemical, optical, and physical data collected on R\/V Endeavor during cruise EN575  from 2016-03-04 to 2016-03-11. These data include Nitrogen, PAR, depth, dissolved Oxygen, fluorescence, salinity calculated from CTD primary sensors, water pressure, and water temperature. The instruments used to collect these data include CTD Sea-Bird MicroCAT 37, Membrane Inlet Mass Spectrometer, Sea-Bird SBE 43 Dissolved Oxygen Sensor, Wet Labs ECO Puck, and towed undulating vehicle. These data were collected by R. Timothy Short and Strawn Toler of SRI International, Richard D. Ricketts of University of Minnesota Duluth, and Brice Loose of University of Rhode Island as part of the \"Collaborative Research:  Inventories of Primary Productivity by In-situ Mass Spectrometry in the Upper Ocean (ZIPP)\" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2021-03-16.\n\nThe following is the text of the dataset description provided by BCO-DMO:\n\nAcquisition Description:\nData collected from Pt. Everglades, Florida to Narragansett Bay, Rhode Island, crossing Gulf Stream and several mesoscale eddies between 28 and 40 N. The SWIMS instrument uses a quadrupole mass analyzer to measure in-situ gas concentration. Ion currents were calibrated using an in-situ calibration technique and a Recurrent Neural Network to remove bias introduced by pressure and temperature changes on the membrane inlet.\n\nIn this application we towed the mass-spectrometer through water depths from 0 to 150 m aboard a Triaxus tow vehicle, corresponding to region where sunlight penetrates the surface ocean. The SWIMS was used to measure oxygen, argon, carbon dioxide, and nitrogen in seawater.",
