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 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.

Measurement data from this cruise are available in computer readable format from NCEI accession 0175298 and from the World Ocean Database (cruise JP044322). See Documentation section on the dataset landing page.

This dataset is U.S. State Department MSR U2018-008 as part of the World Data Service for Oceanography.

Data are in PDF.
