This dataset contains underway measurements of pCO2, salinity, sea surface temperature, and other parameters collected in the Pacific ocean on the R/V Thomas G. Thompson in 2016. Cruise name: 2016_TN340_uwpco2.csv, and expocode: 325020160302. The cruise started and ended in San Diego, CA, and was in support of the Tropical Atmosphere Ocean (TAO) Array. This effort was conducted in support of NOAA's Climate Program Office (CPO), and Ocean Acidification Program (OAP).
The major objectives of the project were to and to continue a time series documenting the distribution of surface and atmospheric fCO2, salinity, temperature, and other parameters, and to characterize and map the key indicators of ocean acidification (OA) across the Pacific Ocean.

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 A71212, with an NIST traceable model 5610 thermistor probe, serial number B2C0403. Accurate to plus/minus 0.01degrees Celsius.;
How was pressure inside the equilibrator measured: Setra 239 differential pressure transducer, accurate to plus/minus 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.;
Drying method for gas: From Pierrot, et al.: Sample air is dried in a condenser that is cooled to 4-5 oC 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 degrees Celsius. 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 7000, IRG4-1045;
SEA CO2 gas detector resolution: 0.2 uatm;
SEA CO2 gas detector uncertainty: 0.3 uatm for equilibrator measurements, 0.2 uatm for atmospheric measurements;
Standardization technique: The system runs a full cycle in approximately 4 hours. The cycle starts with 4 standard gases, then measures three rounds of 5 atmopherice samples followed by 70 surface water samples. Each new gas is flushed through the Licor Analyzer for 2 minutes prior to a stop-flow measurement.;
Standardization frequency: Every 4 hours;
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.;

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.
