This dataset includes surface underway, chemical, meteorological and physical data collected aboard the CCGS Amundsen during the Canadian Arctic Archipelago cruise (EXPOCODE 18DL20130726) from 2013-07-26 to 2013-09-13. These data include partial pressure of carbon dioxide (pCO2), barometric pressure, sea surface salinity and sea surface temperature. The instruments used to collect these data include CO2 gas analyzer and shower head chamber equilibrator for autonomous CO2 measurement.
The major objectives of this cruise is to provide a high quality measurements of atmospheric and sea surface pCO2, sea surface salinity, temperature, and other parameters in the Canadian Arctic Arcipelago.

Parameter or Variable: pCO2 (fCO2) autonomous;
Abbreviation: pCO2_SW_Uatm; fCO2_SW_uatm; xCO2_EQU_ppm;
Unit: uatm, ppm;
Observation type: Surface underway;
Measured or calculated: Measured;
Sampling instrument: Seawater pump;
Location of seawater intake: engine room of CCGS Amundsen;
Analyzing instrument: Infrared Analyzer: LI-COR model 7000;
Detailed sampling and analyzing information: This automated underway system operates by directing the seawater flow from a high-volume inlet (located approximately at 7 m beneath the water surface) through a shower-type equilibrator system. The gas in the headspace of the equilibrator is cycled in a closed loop through a LI-COR LI-7000 CO2/H2O gas analyzer at a rate of 80-100 ml min-1 to measure CO2 and H2O mole fraction. See Pierrot, D., C. Neil, K. Sullivan, R. Castle, R. Wanninkhof, H. Lüger, T. Johannessen, A. Olsen, R. A. Feely, and C. E. Cosca (2009), Recommendations for autonomous underway pCO2 measuring systems and data reduction routines, Deep-Sea Res II, 56, 512-522;
Equilibrator type: shower-type equilibrator;
Is the equilibrator vented or not: Vented;
Water flow rate: 2.4-2.8 L/min;
Gas flow rate: ~100 ml/min;
How was temperature inside the equilibrator measured: Temperature inside the equilibarator measured with a very accurate (±0.01 °C) and stable Hart digital thermometer with a thermistor probe. However, we applied a temperature correction to account for warming from the seawater intake line to the GO 8050 equilibrator. The temperature correction was done with a regression analysis between the equilibrator water temperature and it's coincident seawater measurements made bt the shup's CTD-rosette. The computed SST values from this linear relationship are the temperatures at which our pCO2 values are reported. Details about this regression, and the statistics of it are included in the second tab of this spreadsheet.;
How was pressure inside the equilibrator measured: pressure of gas analyzer (TE connectivity), 13A-015A pressure sensor; sensor was logged to save measurements every minute; accuracy of 0.1% for pressure sensor.;
Drying method for gas: The heaspace gas from the equilibrator goes through a condensor, then Naphion drying tubes, then to the CO2 analyzer;
SEA CO2 gas detector manufacturer: Licor, Inc;
SEA CO2 gas detector model: Licor 7000;
SEA CO2 gas detector resolution: The accuracy of the instrument is nominal ±1% (see Pierrot et al. 2009);
SEA CO2 gas detector uncertainty: The precision of the measurements is ± 1 ppm (see Pierrot et al. 2009);
Standardization technique: The system runs a full cycle in approximately 7 hours. The cycle starts with 4 standard gases, then measures three rounds of 6 atmopherice samples followed by 50 surface water samples. Each new gas is flushed through the Licor Analyzer for 2 minutes prior to a stop-flow measurement.;
Standardization frequency: Every 7 hours;
Standard gas manufacturer: zero CO2 gas (ultra-pure N2 gas from Praxair), and two span gases (373.07 ppm and 600.02 ppm from Praxair);
Standard gas uncertainty: 0.01 ppm;
Water vapor correction method: Details of the data reduction are described in Pierrot, et.al. (2009).;
Temperature correction method: Details of the data reduction are described in Pierrot, et.al. (2009).;
At what temperature was pCO2 reported: In situ sea surface temperature;
Uncertainty: accuracy better than 0.05 deg C for temp. sensor of gas analyzer;

carbon dioxide (CO2) gas analyzer
carbon dioxide (CO2) gas analyzer
measures gaseous carbon dioxide
Carbon dioxide gas analyzer has often been referred to as LI-COR, because a lot of researchers choose to use products manufactured by LI-COR incorporation for their carbon dioxide measurement. The main component of a carbon dioxide analyzer is a nondispersive infrared (NDIR) spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption.
Carbon dioxide (CO2) gas analyzer works together with carbon dioxide (CO2) equilibrator (insttypes_id 184) to measure carbon dioxide in the water.
To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water.
showerhead equilibrator
showerhead equilibrator
extracts dissolved CO2 from water
A carbon dioxide equilibrator is usually in the shape of a vertical tube, with a showerhead on the top, some headspace, a lot of beads to increase the surface exchange area between water and air, a water seal device at the bottom to allow water to overflow, but prevents air exchange between inside and outside.
Carbon dioxide (CO2) equilibrator works together with carbon dioxide (CO2) gas analyzer (insttypes_id 183) to measure carbon dioxide in the water.
