This dataset consists of surface underway, chemical, meteorological and physical data collected during R/V Cefas Endeavour CEND coastal cruises in the North Atlantic Ocean, English Channel and North Sea from 2014-01-30 to 2014-12-29. These data include air-sea difference of partial pressure of carbon dioxide (pCO2), pCO2 in atmosphere, pCO2 in the water, sea surface salinity and sea surface temperature. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.
