These data include underway measurements of partial pressure of carbon dioxide (pCO2) in the equilibrator headspace (dry) at equilibrator temperature, barometric pressure, sea surface temperature, sea surface salinity, discrete measurements of dissolved inorganic carbon, total alkalinity and stable oxygen isotope data. These data were collected by Tim Papakyriakou, Tonya Burgers and Sebastian Luque of University of Manitoba, Canada, Brent Else of University of Calgary, Canada, Helmuth Thomas of Dalhousie University, Canada, and Alfonso Mucci of McGill University, Canada as part of the CCGS Amundsen Canadian Arctic, ArcticNet cruises during the 2013-2014.
