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). Digital 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 This dataset is U.S. State Department MSR U2020-017 as part of the World Data Service for Oceanography. Data are in PDF report.
