Water temperature, salinity, oxygen, currents and others taken by CTD, Niskin bottles, and ADCP from the research vessel Keifu Maru, cruise 12-02, in the North Pacific Ocean from 2012-02-14 to 2012-02-16 (NCEI Accession 0220613)

The cruise was carried out during the period from February to March, 2012. 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 165 degree East.

Water samples were analyzed for salinity, dissolved oxygen, nutrients, pH and phytopigment (chlorophyll-a and phaeopigments). Current data was measured by ship-mounting Acoustic Doppler Current Profiler. This dataset is U.S. State Department MSR U2011-023 as part of the World Data Service for Oceanography Data are in PDF.
