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 HAKUREI MARU in the North Pacific Ocean and South Pacific Ocean from 1993-08-07 to 1993-10-05 (NCEI Accession 0112229)

This dataset includes biological, chemical, discrete sample, physical and profile data collected from HAKUREI MARU in the North Pacific Ocean and South Pacific Ocean from 1993-08-07 to 1993-10-05 and retrieved during cruise NH93-2 and PACIFICA_49HG19930807. These data include ALKALINITY, Chlorophyll a, 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 Yutaka W. Watanabe of Hokkaido University and Ko Harada of (NIRE) National Institute for Resources and Environment (now AIST) as part of the PACIFICA_49HG19930807 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.
