Partial pressure (or fugacity) of carbon dioxide, salinity and other variables collected from surface underway observations using carbon dioxide (CO2) gas analyzer, shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement and other instruments from R/V Keifu Maru II in the Pacific Ocean, East China Sea and Sea of Japan in 2015 (NCEI Accession 0169101)

NCEI Accession 0169101 includes Surface underway data collected from R/V Keifu Maru II in the Pacific Ocean, East China Sea and Sea of Japan, from 2015-01-08 to 2015-11-30. These data include barometric pressure, partial pressure (or fugacity) of carbon dioxide - atmosphere, partial pressure (or fugacity) of carbon dioxide - water, sea surface salinity and sea surface temperature. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer, shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement. These data were collected by Shu Saito of Marine Division, Global Environment and Marine Department, Japan Meteorological Agency as part of the SOOP_Keifu_Maru_II_2015 data set.
