This dataset contains data from underway fCO2 (seawater and atmospheric), temperature, and salinity measurements collected on 4 equatorial Pacific cruises from 2005-02-18 to 2005-08-10 as part of a ship-of-opportunity time-series. Cruise names and expocodes: KA2005_01 (33KM2005021), KA2005_02 (33KM20050406), KA2005_03 (33KM20050610), KA2005_04 (33KM20050716). Since 1982, NOAA's Pacific Marine Environmental Laboratory has made underway CO2 observations in the equatorial Pacific as a companion project to the Global Tropical Moored Buoy Array. This effort was conducted with the support of NOAA's Global Ocean Monitoring and Observing Program.
This dataset is available to the public for a wide variety of uses including scientific research and analysis.

Parameter or Variable: pCO2 (fCO2) autonomous;
Abbreviation: fCO2W@SST_uatm;
Unit: uatm;
Observation type: Surface underway;
In-situ / Manipulation / Response variable: In-situ observation;
Measured or calculated: Measured;
Sampling instrument: Seawater pump;
Location of seawater intake: Bow;
Analyzing instrument: General Oceanics 8050. PMEL system ID: PMEL3;
Detailed sampling and analyzing information: The sampling and analyzing methods of the Neill/General Oceanics Underway pCO2 systems are described in detail in: Pierrot, D.; Neill, C.; Sullivan, K.; Castle, R.; Wanninkhof, R.; Luger, H.; Johannessen, T.; Olsen, A.; Feely, R.A.; and Cosca, C.E. (2009). Recommendations for autonomous underway pCO2 measuring systems and data-reduction routines. Deep-Sea Res., II, v. 56, pp. 512-522.;
Equilibrator type: Shower head;
Equilibrator volume: ~0.5 L;
Is the equilibrator vented or not: Vented;
Water flow rate: 3 L/min;
Gas flow rate: ~0.8 L/m;
How was temperature inside the equilibrator measured: Hart Scientific model 1521 digital thermometer, serial number A71211, with an NIST traceable model 5610 thermistor probe, serial number A692802. Accurate to ± 0.01°C.;
How was pressure inside the equilibrator measured: Setra 239 differential pressure transducer, accurate to ± 0.15 hPa. The equilibrator was passively vented to a secondary equilibrator, and the Licor sample output was vented to the laboratory when CO2 measurements were made, thus equilibrator headspace pressure was assumed to be laboratory pressure. Pressure in the laboratory was measured with a GE Druck barometer, with an accuracy of ± 0.01 %fs.;
Drying method for gas: From Pierrot, et al.: Sample air is dried in a condenser that is cooled to 4-5 °C by a Peltier thermoelectric device. This partially dried air flushes a chamber that is vented and remains at ambient pressure. The dried air inside the chamber is used as the counter flow in the Nafion® tubing. A vacuum pump pulls the dried air from the chamber first through a fixed restrictor and then through the Nafion® tubes, thus creating an absolute pressure and corresponding partial pressure gradient for water vapor across the membrane. When atmospheric air is measured, some of the partially dried air (80- 100 ml/min) is pushed through a Nafion® tube, the analyzer and out a vent instead of flushing the chamber. The headspace gas, when being measured, is circulated in a closed loop through the analyzer at a rate similar to that of the atmospheric air (80-100 ml/min). It is dried first in the condenser, then in a Nafion® tube prior to entering the analyzer and being returned to the equilibrator. Typically, the water mole fraction (xH2O) in the dried gas is about 2 parts per thousand (ppt), which corresponds to a dew point temperature of about -20 °C. The liquid water condensed out of the sample air streams is removed by peristaltic pumps into the vent equilibrator at intervals determined by the user.;
SEA CO2 gas detector manufacturer: Licor, Inc;
SEA CO2 gas detector model: Licor 6262, IRG3-1295;
SEA CO2 gas detector resolution: 0.2 µatm;
SEA CO2 gas detector uncertainty: 0.3 µatm for equilibrator measurements, 0.2 µatm for atmospheric measurements;
Standardization technique: The system runs a full cycle in approximately 112 minutes. The cycle starts with 4 standard gases, then measures three rounds of 10 atmopherice samples followed by 60 surface water samples. Each new gas is flushed through the Licor Analyzer for 4 minutes prior to a 10 second reading from the analyzer during which the sample cell is open to the atmosphere. Subsequent samples of the same gas are flushed through the Licor Analyzer for 30 seconds prior to a stop-flow measurement.;
Standardization frequency: Every 112 minutes;
Standard gas manufacturer: Standard gases are supplied by NOAA’s Earth System Research Laboratory, Global Monitoring Division, in Boulder, CO, and are directly traceable to the WMO scale.;
Standard gas concentration: CA04403, 363.96 ppm; CA01721, 414.00 ppm; CA02947, 365.56 ppm; CA01906, 505.58 ppm;
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: ± 2 µatm;
Quality flag convention: WOCE quality control flags are used: 2 = good value, 3 = questionable value, 4 = bad value;

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.

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.
