Partial pressure (or fugacity) of carbon dioxide, salinity and other variables collected from Surface underway observations using Carbon dioxide (CO2) gas analyzer, Micro-porous membrane equilibrator for discrete carbon dioxide measurement and other instruments from the SOYO-MARU in the North Pacif

NODC Accession 0117672 includes Surface underway, chemical, meteorological and physical data collected from SOYO-MARU in the North Pacific Ocean, Philippine Sea and Sea of Japan from 2010-11-12 to 2011-07-17 and retrieved during cruise SY101112, SY110521 and SY110712. These data include BAROMETRIC PRESSURE, Partial pressure (or fugacity) of carbon dioxide - water, SALINITY and SEA SURFACE TEMPERATURE. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer and Micro-porous membrane equilibrator for discrete carbon dioxide measurement. These data were collected by Tsuneo Ono and Tadafumi Ichikawa of National Research Institute of Fisheries Science as part of the VOS_Soyo_Maru_2011 data set.

The Global Volunteer Observing Ship (VOS) Program is coordinated by the UNESCO International Ocean Carbon Coordination Project (IOCCP). International groups from 14 countries have been outfitting research ships and commercial vessels with automated CO2 sampling equipment to analyze the carbon exchange between the ocean and atmosphere.
