Water temperature, salinity, oxygen, currents and others taken by CTD, Niskin bottles, and ADCP from the research vessel Ryofu Maru, cruise 18-06, in the north Pacific from 2018-08-18 to 2018-08-20 (NCEI Accession 0220931)

This dataset contains water temperature, salinity, oxygen, currents and others taken by CTD, Niskin bottles, and ADCP from the research vessel Ryofu Maru, cruise RF18-06, in the north Pacific. The entire cruise was carried out during the period from August to September, 2018. 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）. Floating tar balls were sampled by ship-towing Neuston net.
