PACKAGE DESCRIPTION: 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 Japan Agency for Marine-Earth Science and Technology (Jamstec) as part of the CLIVAR_P21_2009 and Underway_P21_2009 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.

Curve fitting method: Measurement of AT was made based on spectrophotometry using a custom-made system (Nippon ANS, Inc.). The system comprises of a water dispensing unit, an auto-burette (765 Dosimat, Metrohm), and a spectrophotometer (Carry 50 Bio, Varian), which are automatically controlled by a PC.
Uncertainty: CRM, batches 92, certified value = 2201.91 μmol kg-1 The average and standard deviation of absolute values of differences of AT analyzed consecutively were 0.5 and 0.5 μmol kg-1 (n = 200), and 0.6 and 0.5 μmol kg-1 (n = 165) for legs 1 and 2, respectively. The combined values were calculated to be 0.5 and 0.5 μmol kg-1 (n = 365).
