    • Water temperature, salinity, oxygen, currents and others taken by CTD, Niskin bottles, and ADCP from the research vessel Ryofu Maru, cruise 19-06, in the north Pacific from 2019-08-20 to 2019-08-22 (NCEI Accession 0221020)

    Metadata Updated: July 1, 2025

    This dataset contains water temperature, salinity, oxygen, currents and other data taken by CTD, Niskin bottles, and ADCP from the research vessel Ryofu Maru, cruise RF19-06, in the north Pacific. The entire cruise was carried out during the period from August to September, 2019. 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).

    This dataset is U.S. State Department MSR U2019-010 as part of the World Data Service for Oceanography.

    Data are in PDF.
