Processing Steps
  • Parameter or Variable: pCO2 (fCO2) autonomous; Abbreviation: xCO2, fCO2 (calculated), pCO2 (calculated); Unit: ppm; Observation type: Surface underway; Measured or calculated: xCO2 measured in wet air; Calculation method and parameters: pCO2 calculation following T correction of Takahashi et al 1993 (where T_membrane is considered T_in-situ since distance membrane to inlet is 0.5m). pCO2 and fCO2 are calculated following the DOE handbook and corrected for water vapour following Weiss and Price 1980.; Sampling instrument: Seawater pump; Location of seawater intake: variable - max 2m below sea surface; Analyzing instrument: NDIR, flat membrane, closed loop, Licor Li-840A; Equilibrator type: NDIR, flat membrane, closed loop; Is the equilibrator vented or not: No. Closed loop; Water flow rate: 7 L/min; Gas flow rate: ~0.5 L/m; How was temperature inside the equilibrator measured: Hart Scientific model 1523 digital thermometer, serial number A1320065, with an NIST traceable model 5610 thermistor probe, serial number BB011803. 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.; Drying method for gas: From Pierrot et al.: Sample air is dried in a condenser that is cooled to 4-5 degrees Celsius 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 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 7000, IRG4-0221; 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: Autocalibration with Zero (Soda lime) and 466 ppm standard; Standardization frequency: once per day; Standard gas manufacturer: LOCEAN; Standard gas concentration: compressed air (diving facility) 200Bar in 0.5L AL-tank gas referenced with two standards from LOCEAN: 452.03 ppm and 352.49 ppm Measured: 436.7 ppm (2019-10-02); Standard gas uncertainty: better than 1% of reading, zero drift 0.15 ppm/°C, span drift 0.03 %/°C; Researcher name: Toste Tanhua; Researcher institution: GEOMAR Helmholtz Centre for Ocean Research Kiel, Kiel, Germany.
