  • Parameter or Variable: xCO2 SW (wet); Abbreviation: xCO2 SW (wet); Unit: [μmol/mol]; Controlled vocabulary name: partial pressure of carbon dioxide - water; Observation type: surface underway; In-situ / Manipulation / Response variable: in-situ; Sampling instrument: ASVCO2 (NOAA trademark); Analyzing instrument: Absolute, non-dispersive infrared (NDIR) gas analyzer; LI-820; Sensor manufacturer: NOAA PMEL; Duration: 1hr cycle; Detailed sampling and analyzing information: At the beginning of each sample, the instrument self-calibrates using a zero and high standard. The zero standard is generated by cycling a small amount of air through a soda lime chamber. The high standard is from a cylinder of calibrated standard reference gas, 396.21 umol/mol, from ESRL. ESRL standards are traceable to WMO x93 scale with a stated reproducibility of 0.06 micromole/mole.

We have found that the oxygen does not come to complete equilibrium so any rapid changes in oxygen do not get properly captured using this system. Therefore, we tend to use the oxygen data only as a qualitative sense of the biology. It is not a quantitative measure.
