    "description": "This dataset contains water temperature, salinity, oxygen, currents and other data taken by CTD, Niskin bottles, and ADCP from the research vessel Keifu Maru, cruise KS20-02, in the north Pacific. The entire cruise was carried out during the period from January to March, 2020. 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 165E. 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\nThis dataset is U.S. State Department MSR U2019-026 as part of the World Data Service for Oceanography.\n\nData are in PDF.",
