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)

NCEI 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. 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 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 Department as part of the RY40N data set. CDIAC associated the following cruise ID(s) with this data set: 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.
