Beaufort Gyre Observing System (BGOS) Underway pCO2 data and air-sea CO2 fluxes

These data were collected on the CCGS Louis St. Laurent during BGOS research cruises in 2012, 2013, 2014 and 2016 in the Beaufort Sea area. They are underway pCO2 data collected using an equilibrator-infrared method (SUPER CO2 system from Sunburst Sensors). Ancillary data for calculation of air-sea CO2 fluxes include temperature, salinity, atmospheric CO2, wind speed, and gas transfer velocity (calculated from Wanninkhof et al. (2009). Fluxes are not corrected for fractional ice-coverage.
