PACKAGE DESCRIPTION: This dataset includes biological, chemical, discrete sample, optical, physical and profile data collected from MIRAI in the Bismarck Sea, North Pacific Ocean and South Pacific Ocean from 2011-01-12 to 2012-02-09. These data include CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-113 (CFC-113), CHLOROFLUOROCARBON-12 (CFC-12), CHLOROPHYLL A, DISSOLVED INORGANIC CARBON (DIC), DISSOLVED OXYGEN, FLUORESCENCE, HYDROSTATIC PRESSURE, NITRATE, NITRITE, PHOTOSYNTHETIC ACTIVE RADIATION (PAR), Potential temperature (theta), SALINITY, SULFUR HEXAFLUORIDE (SF6), TOTAL ALKALINITY (TA), WATER TEMPERATURE, pH, phosphate and silicate. The instruments used to collect these data include CTD, PAR Sensor and bottle.
These data were collected by Akihiko Murata and Yuichiro Kumamoto of Japan Agency for Marine-Earth Science and Technology (JAMSTEC) as part of the CLIVAR_P10_2011 data set. CDIAC associated the following cruise ID(s) with this data set: MR11-08
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.

| Measured or calculated: |
Calculated |
| Detailed sampling and analyzing information: |
Measurements of CT were made with two total CO2 measuring systems (systems-C and -D; Nippon ANS, Inc.), which are slightly different from each other. The systems comprise of a seawater dispensing system, a CO2 extraction system and a coulometer (Model 3000, Nippon ANS, Inc.). |

| Type of titration: |
spectrophotometry |
| 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 Scan, Varian), which are automatically controlled by a PC. |
| Uncertainty: |
The average and standard deviation of absolute values of differences of AT analyzed consecutively were 0.5 and 0.4 μmol kg-1 (n = 96), and 0.5 and 0.4 μmol kg-1 (n = 88) for legs 2 and 3, respectively. The combined values were calculated to be 0.5 and 0.4 μmol kg-1 (n = 184). |

| Temperature of pH measurement: |
25 °C |
| Detailed sampling and analyzing information: |
Measurement of pH was made by a pH measuring system (Nippon ANS, Inc.), which adopts spectrophotometry. The system comprises of a water dispensing unit and a spectrophotometer (Carry 50 Scan, Varian).25 |
| Uncertainty: |
The average and standard deviation of absolute values of differences of pH analyzed consecutively were 0.0006 and 0.0006 pH unit (n = 116), and 0.0008 and 0.0010 pH unit (n = 109) for legs 1 and 2, respectively. The combined values were 0.0007 and 0.0008 pH unit (n = 225). We compared observed pH and pH calculated from CT and AT. The average and standard deviation was 0.0102 and 0.0072 pH unit, respectively. Thus the accuracy of pH was estimated to be 0.01 pH unit at best. |
