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 the KEIFU MARU in the East

NODC Accession 0116977 includes Surface underway, chemical, meteorological and physical data collected from KEIFU MARU in the East China Sea (Tung Hai), North Pacific Ocean, Philippine Sea, Sea of Japan and South Pacific Ocean from 2012-10-24 to 2013-08-27 and retrieved during cruise 49UF20121024. These data include BAROMETRIC PRESSURE, Partial pressure (or fugacity) of carbon dioxide - atmosphere, 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, Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement, not applicable and thermosalinographs. These data were collected by Shu Saito and Akira Nakadate of Japan Meteorological Agency; Pollutants Chemical Analysis Center; Marine Division; Global Environment and Marine Depertment as part of the VOS_Keifu_Maru_2012_2013 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.
