Partial pressure (or fugacity) of carbon dioxide, salinity and other variables collected from Surface underway observations using Barometric pressure sensor, Carbon dioxide (CO2) gas analyzer and other instruments from the Atlantic Companion in the Irish Sea and St. George's Channel and North Atlan

NODC Accession 0115715 includes Surface underway, chemical, meteorological and physical data collected from Atlantic Companion in the Irish Sea and St. George's Channel and North Atlantic Ocean from 2011-12-05 to 2011-12-13 and retrieved during cruise 77CN20111205. 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 Barometric pressure sensor, Carbon dioxide (CO2) gas analyzer, Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement and thermosalinographs. These data were collected by Tobias Steinhoff and Arne Körtzinger of Leibniz Institut Fur Meereswissenschaften as part of the VOS_Atlantic_Companion_Line_2011_COM11_20 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.
