Dissolved inorganic carbon, pH, alkalinity, temperature, salinity and other variables collected from discrete sample and profile observations using CTD, bottle and other instruments from the RYOFU MARU in the North Pacific Ocean from 2000-04-20 to 2000-05-24 (NCEI Accession 0115282)

This dataset includes biological, chemical, discrete sample, physical and profile data collected from RYOFU MARU in the North Pacific Ocean from 2000-04-20 to 2000-05-24 and retrieved during cruise PACIFICA_49RY20000420 and RF00-04. 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 and bottle. These data were collected by Naoki Nagai of Japan Meteorological Agency; Pollutants Chemical Analysis Center; Marine Division; Global Environment and Marine Department and Masao Ishii of Meteorological Research Institute as part of the PACIFICA_49RY20000420 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.
