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 RYOFU MARU in the North Pacific Ocean and Philippine Sea from 2000-06-20 to 2000-07-31 (NCEI Accession 0112278)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 06, 2026 at 01:26 AM | Dataset Last Updated: February 21, 2016 at 12:00 AM
This dataset includes discrete sample and profile data collected from RYOFU MARU in the North Pacific Ocean and Philippine Sea from 2000-06-20 to 2000-07-31 and retrieved during cruise PACIFICA_49RY20000620 and RF00-06. These data include AMMONIUM (NH4), BAROMETRIC PRESSURE, CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), Chlorophyll a, DELTA CARBON-13, DISSOLVED INORGANIC CARBON (DIC), DISSOLVED ORGANIC CARBON, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRITE, PHAEOPHYTIN, Potential temperature (theta), SALINITY, SIGMA-THETA, TOTAL ALKALINITY (TA), TOTAL PHOSPHORUS, WATER TEMPERATURE, nitrate + nitrite content (concentration), pH, phosphate and silicate. The instruments used to collect these data include CTD, Coulometer for DIC measurement and bottle. These data were collected by Hitomi Kamiya 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_49RY20000620 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.
