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 KEIFU MARU in the North Pacific Ocean and Philippine Sea from 2000-05-09 to 2000-06-

NODC Accession 0112201 includes biological, chemical, discrete sample, physical and profile data collected from KEIFU MARU in the North Pacific Ocean and Philippine Sea from 2000-05-09 to 2000-06-09 and retrieved during cruise KE00-04 and PACIFICA_49FA20000509. These data include ALKALINITY, AMMONIUM, CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), CHLOROPHYLL A, DELTA CARBON-13, DISSOLVED INORGANIC CARBON, DISSOLVED ORGANIC CARBON, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRATE + NITRITE CONTENT (CONCENTRATION), NITRITE, PHAEOPHYTIN, PHOSPHATE, Potential temperature (theta), SALINITY, SIGMA-THETA, SILICATE, TOTAL PHOSPHORUS, WATER TEMPERATURE and pH. The instruments used to collect these data include CTD, Coulometer for DIC measurement and bottle. These data were collected by Akimasa Okano of Japan Meteorological Agency and Masao Ishii of Meteorological Research Institute; Geochemical Research Department as part of the PACIFICA_49FA20000509 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.
