Partial pressure (or fugacity) of carbon dioxide, water temperature, salinity and other variables collected from surface underway observations from R/V Mirai GO-SHIP WHP P01 revisit cruise MR21-04 (EXPOCODE 49NZ20210717) in the North Pacific Ocean from 2021-07-17 to 2021-08-20 (NCEI Accession 0292021)

This dataset includes surface underway, chemical, meteorological and physical data collected from R/V Mirai GO-SHIP WHP P01 revisit cruise MR21-04 (EXPOCODE 49NZ20210717) in the North Pacific Ocean from 2021-07-17 to 2021-08-20 . These data include water temperature, barometric pressure, partial pressure (or fugacity) of carbon dioxide - atmosphere, partial pressure (or fugacity) of carbon dioxide - water. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.
