Surface underway seawater partial pressure of carbon dioxide (pCO2), sea surface salinity, temperature and barometric pressure data measured on board R/V Soyo-Maru during the Fisheries Research Agency (FRA) near-Japan pCO2 cruises project in North Pacific Ocean and Japan Sea from 2018-04-17 to 2018-12-07 (NCEI Accession 0186070)
PACKAGE DESCRIPTION: This dataset includes surface underway data collected from R/V Soyo-Maru during the Fisheries Research Agency (FRA) near-Japan pCO2 cruises project in North Pacific Ocean and Japan Sea from 2018-04-17 to 2018-12-07. These data include partial pressure of carbon dioxide (CO2) - atmosphere, partial pressure of CO2 - water, sea surface salinity, sea surface temperature and barometric pressure. The instruments used to collect these data include CO2 gas analyzer, shower head chamber equilibrator for autonomous CO2 measurement.
