Partial pressure (or fugacity) of carbon dioxide, dissolved inorganic carbon, pH, alkalinity, temperature, salinity and other variables collected from discrete sample, profile and underway - surface observations using Alkalinity titrator, CTD and other instruments from the MIRAI in the Coral Sea, North Pacific Ocean and others from 2009-04-10 to 2009-07-03 (NCEI Accession 0108084)

This dataset includes chemical, discrete sample, meteorological, physical, profile and underway - surface data collected from MIRAI in the Coral Sea, North Pacific Ocean, Philippine Sea, Solomon Sea and South Pacific Ocean from 2009-04-10 to 2009-07-03 and retrieved during cruise 49NZ20090410 and 49NZ20090521. These data include AIR TEMPERATURE, ALKALINITY, BAROMETRIC PRESSURE, CARBON DIOXIDE - AIR, CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-113 (CFC-113), CHLOROFLUOROCARBON-12 (CFC-12), DELTA CARBON-13, DELTA CARBON-14, DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRITE, PHOSPHATE, Partial pressure (or fugacity) of carbon dioxide, Potential temperature (theta), SALINITY, SEA SURFACE TEMPERATURE, SIGMA-T, SILICATE, WATER TEMPERATURE, WIND DIRECTION, WIND SPEED and pH. The instruments used to collect these data include Alkalinity titrator, CTD, Carbon dioxide (CO2) gas analyzer, Coulometer for DIC measurement, Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement, Spectrophotometer for pH measurement and bottle. These data were collected by Akihiko Murata of Meteorological Research Institute as part of the CLIVAR_P21_2009 and Underway_P21_2009 dataset.

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.
