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 in the North Pacific Ocean and South Pacific Ocean from 2011-05-15 to 201

NODC Accession 0115178 includes biological, chemical, discrete sample, physical and profile data collected from RYOFU MARU in the North Pacific Ocean and South Pacific Ocean from 2011-05-15 to 2011-08-26 and retrieved during cruise CLIVAR_P13_2011, RF11-06, RF11-07 and RF11-08. These data include ALKALINITY, CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), CHLOROPHYLL A, DELTA CARBON-13, DELTA CARBON-14, DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE + NITRITE CONTENT (CONCENTRATION), NITRITE, PHAEOPHYTIN, PHOSPHATE, Potential temperature (theta), SALINITY, SIGMA-THETA, 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 Toshiya Nakano and Hitomi Kamiya of Japan Meteorological Agency; Pollutants Chemical Analysis Center; Marine Division; Global Environment and Marine Depertment as part of the CLIVAR_P13_2011 data set.

The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.
