Partial pressure (or fugacity) of carbon dioxide, salinity and other variables collected from underway - surface observations using Carbon dioxide (CO2) gas analyzer, Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement and other instruments from the Pyxis in the Bering

NODC Accession 0081041 includes chemical, meteorological, physical and underway - surface data collected from Pyxis in the Bering Sea, Caribbean Sea, Coastal Waters of SE Alaska, East China Sea (Tung Hai), Gulf of Mexico, Gulf of the Farallones National Marine Sanctuary, Inland Sea (Seto Naikai), Monterey Bay National Marine Sanctuary, North Atlantic Ocean, North Pacific Ocean, Olympic Coast National Marine Sanctuary, Papahanaumokuakea Marine National Monument, Philippine Sea and South China Sea (Nan Hai) from 2001-11-06 to 2013-04-25 and retrieved during cruise PX66E - PX141W. These data include ABSOLUTE HUMIDITY, AIR TEMPERATURE, AIR-SEA DIFFERENCE - PARTIAL PRESSURE (OR FUGACITY) OF CARBON DIOXIDE, BAROMETRIC PRESSURE, CARBON DIOXIDE - AIR, INCOMING SOLAR RADIATION, Partial pressure (or fugacity) of carbon dioxide, SALINITY, SEA SURFACE TEMPERATURE, SEDIMENT PROPERTIES and WIND SPEED. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer and Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement. These data were collected by Yukihiro Nojiri of National Institute for Environmental Studies as part of the VOS_Pyxis_Line 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.
