Dissolved inorganic carbon, pH, alkalinity, temperature, salinity and other variables collected from discrete sample and profile observations using CTD, Coulometer for DIC measurement and other instruments from the OSHORO MARU in the North Pacific Ocean from 2003-05-10 to 2003-05-23 (NODC Accession

NODC Accession 0112274 includes chemical, discrete sample, physical and profile data collected from OSHORO MARU in the North Pacific Ocean from 2003-05-10 to 2003-05-23 and retrieved during cruise OS135-KNOT and PACIFICA_49OS20030510. These data include ALKALINITY, AMMONIUM, DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRITE, PHOSPHATE, SALINITY, SILICATE, WATER TEMPERATURE and pH. The instruments used to collect these data include CTD, Coulometer for DIC measurement and bottle. These data were collected by Nobuo Tsurushima of Advanced Industrial Science and Technology as part of the PACIFICA_49OS20030510 data set.

PACIFICA (PACIFic ocean Interior CArbon) was an international collaborative project for the data synthesis of ocean interior carbon and its related parameters in the Pacific Ocean. The North Pacific Marine Science Organization (PICES), Section of Carbon and Climate (S-CC) supported the project.
