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 Ryofu Maru II in the North Pacific Ocean from 2006-06-07 to 2006-06-29 (NCEI Accession 0112291)

NODC Accession 0112291 includes biological, chemical, discrete sample, physical and profile data collected from Ryofu Maru II in the North Pacific Ocean from 2006-06-07 to 2006-06-29 and retrieved during cruise PACIFICA_49RY20060607 and RF06-06 Leg.1. 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 Masahiko Fujimura of Japan Meteorological Agency and Masao Ishii of Meteorological Research Institute; Geochemical Research Department as part of the PACIFICA_49RY20060607 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.
