Partial pressure (or fugacity) of carbon dioxide, temperature, and other variables collected from surface underway observations using carbon dioxide gas analyzer, shower head equilibrator and other instruments from R/V Hakuho Maru Cruises in the North Pacific Ocean between 2011-12-01 and 2013-05-01 (NCEI Accession 0166708)

This dataset includes surface underway, chemical, meteorological and physical data collected from R/V Hakuho Maru Cruises in the North Pacific Ocean between 2011-12-01 and 2013-05-01. These data include measurements of mole fraction of CO2 in ambient atmosphere in dry air, mole fraction of CO2 in air from equilibrator in dry air, atmospheric pressure, sea surface temperature and sea surface salinity. These data were collected by Naohiro Kosugi, Masao Ishii and Daisuke Sasano of Meteorological Research Institute, Japan.
