This dataset includes chemical, discrete sample, physical and profile data collected from Hokusei Maru in the North Pacific Ocean from 1998-07-18 to 1998-08-18 and retrieved during cruise HO98-3 and PACIFICA_49HO19980718. These data include ALKALINITY, AMMONIUM, DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE + NITRITE CONTENT (CONCENTRATION), 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 Shuichi Watanabe of JAMSTEC; Mutsu Institute for Oceanography (MIO) as part of the PACIFICA_49HO19980718 dataset.

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.
