PACKAGE DESCRIPTION: This dataset includes surface underway, chemical, meteorological and physical data collected during R/V Celtic Explorer research cruises in the North Atlantic Ocean, English Channel, Irish Sea, St. Georges Channel and North Sea from 2018-02-10 to 2018-12-14. These data include partial pressure (or fugacity) of carbon dioxide (pCO2) - atmosphere, pCO2 - water, sea surface salinity, sea surface temperature and barometric pressure. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer.

ADDITIONAL INFORMATION: A General Oceanics pCO2 system (model 8050) was used for pCO2 measurements. The system is described in detail in Pierrot et al.(2009). Surface water is pumped continuously from the intake to the equilibrator. The equilibrator contains a water spray head, and as the water flows through it the dissolved CO2 equilibrates with the headspace. The headspace is dried and xCO2 is determined by an infrared sensor. Calculations were performed following Pierrot (2009) and are described in detail in Steinhoff (2010).
