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 2012-07-26 to 2012-09-13 (NODC Accession 0117671)

NODC Accession 0117671 includes biological, chemical, discrete sample, physical and profile data collected from RYOFU MARU in the North Pacific Ocean from 2012-07-26 to 2012-09-13 and retrieved during cruise RF12-06(40N). These data include CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), CHLOROPHYLL A, DISSOLVED INORGANIC CARBON (DIC), DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE + NITRITE CONTENT (CONCENTRATION), NITRITE, PHAEOPHYTIN, PHOSPHATE, Potential temperature (theta), SALINITY, SIGMA-THETA, SILICATE, TOTAL ALKALINITY (TA), WATER TEMPERATURE and pH. The instruments used to collect these data include CTD and bottle. These data were collected by Kazuhiro Nemoto of Japan Meteorological Agency and Toshiya Nakano and Hitomi Kamiya of Japan Meteorological Agency; Pollutants Chemical Analysis Center; Marine Division; Global Environment and Marine Depertment as part of the RY40N 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.
