Water temperature, salinity, oxygen, currents and others taken by CTD, Niskin bottles, and ADCP from the research vessel Ryofu Maru, cruise 13-07, in the North Pacific Ocean from 2013-09-04 to 2013-09-07 (NCEI Accession 0220629)

The entire cruise was carried out during the period from July to September, 2013. 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 179E.

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 U2013-006 as part of the World Data Service for Oceanography Data are in PDF.
