    "title": "Water temperature, salinity, currents, and others taken by CTD and ADCP from the research vessel Keifu Maru, cruise 21-02, in the North Pacific Ocean from 2021-02-22 to 2021-02-23 (NCEI Accession 0227853)",
    "description": "This dataset contains water temperature, salinity, currents, and other chemical and biological parameters taken by CTD and ADCP from the research vessel Keifu Maru (cruise KS21-02) in the North Pacific.  The entire cruise was carried out during the period from February to March, 2021. Hydrographic observation was made using a Sea-Bird Electronics (SBE) 36 position carousel equipped with 10-liter Niskin water sample bottles, a CTD system (SBE911plus) equipped with JFE Advantech oxygen sensor (RINKO III) along longitude 165 degree East. Water samples were analyzed for salinity, dissolved oxygen, nutrients, pH and phytopigment (chlorophyll-a and phaeopigments). Current data was measured by Teledyne RDI's vessel-mounted ADCP system (38kHz Ocean Surveyor).\n\nDigital data from this cruise will be available at http:\/\/www.data.jma.go.jp\/gmd\/kaiyou\/db\/vessel_obs\/data-report\/html\/ship\/cruisedata_e.php?id=KS2102\n\nThis dataset is U.S. State Department MSR U2020-017 as part of the World Data Service for Oceanography. Data are in PDF report.",
