This dataset includes surface underway measurements of partial pressure of carbon dioxide (pCO2), water temperature, salinity, barometric pressure and other variables during R/V Endeavor Atlantic Zone Monitoring Program (AZMP) cruises in Gulf of Maine, Scotian Shelf, Newfoundland Shelf and North Atlantic Ocean from 2017-11-24 to 2017-12-16.

This dataset includes surface underway, chemical, meteorological and physical data collected during the CCGS Amundsen cruise (EXPOCODE 18DL20180525) in Hudson Bay, Labrador Sea from 2018-05-25 to 2018-07-13. These data include partial pressure of CO2 (pCO2), fugacity of CO2 (fCO2), mol fraction of CO2 (xCO2), sea surface salinity and sea surface temperature.

This dataset includes surface underway data collected during USCGC Healy Expeditions in the North Pacific Ocean, Gulf of Alaska, Bering Sea, Chukchi Sea, Beaufort Sea, Arctic Ocean, Davis Strait, Labrador Sea and North Atlantic Ocean from 2021-07-15 to 2021-10-19. These data include barometric pressure, partial pressure carbon dioxide (pCO2) - water, sea surface salinity, sea surface temperature and barometric pressure. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.

This dataset includes surface underway measurements of partial pressure of carbon dioxide (pCO2), water temperature and sea surface salinity collected during the Beaufort Gyre Observing System/Joint Ocean Ice Study onboard the CCGS Louis S. St-Laurent during the Beaufort Gyre Observing System/Joint Ocean Ice Study cruise in the Arctic Ocean, Beaufort Sea and Hudson Strait from 2020-09-07 to 2020-10-13. The Shipboard Underway pCO2 Environmental Recorder (Sunburst Sensors, SUPER-CO2) utilizes a LICOR NDIR (non-dispersive infrared) analyzer coupled to a membrane contactor to equilibrate a gas stream to a flowing seawater sample stream. The membrane equilibrator was tied into the ship’s seawater line at a set flow rate of ~1.5 liters per minute. The SUPER-CO2 uses a Windows based tablet running custom software, developed by Sunburst Sensors, for instrument control, real-time data display and data collection. Three calibration standards (zero CO2, 386 and 710 parts per million CO2) were ran 6 times per day for the duration of the cruise. The raw collected SUPER-CO2 data was processed using a custom written Matlab QC program. The Matlab program calibrates the SUPER-CO2 values to the CO2 standards as well as temperature correcting the SUPER-CO2 to the seawater surface temperature (Dickson, 2007)
