Dissolved inorganic carbon, pH, alkalinity, temperature, salinity and other variables collected from discrete sample and profile observations using CTD, bottle and other instruments from RYOFU MARU in the North Pacific Ocean from 2012-07-26 to 2012-09-13 (NCEI Accession 0117671)

This dataset 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. These data include CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), CHLOROPHYLL A, DISSOLVED INORGANIC CARBON (DIC), DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRITE, PHAEOPHYTIN, Potential temperature (theta), SALINITY, SIGMA-THETA, TOTAL ALKALINITY (TA), WATER TEMPERATURE, nitrate + nitrite content (concentration), pH, phosphate and silicate. The instruments used to collect these data include CTD and bottle.

These data were collected by Hitomi Kamiya, Kazuhiro Nemoto, and Toshiya Nakano of Japan Meteorological Agency (JMA) as part of the RY40N dataset. CDIAC associated the following cruise ID(s) with this dataset: RF12-06(40N)

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.
