Water temperature, salinity, oxygen, currents and others taken by CTD, Niskin bottles, and ADCP from the research vessel Ryofu Maru, cruise 17-02, in the north Pacific from 2017-02-08 to 2017-02-09 (NCEI Accession 0220861)

The entire cruise was carried out during the period from February to March, 2017. 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 Teledyn RDI's vessel-mounted ADCP system（38kHz Ocean Surveyor）. This dataset is U.S. State Department MSR U2016-031 as part of the World Data Service for Oceanography Data are in PDF.
