Oxygen DOXY_QC set to 3: Coriolis DAC implementation

The BGC-Argo data management team decided that DOXY parameter (moles_of_oxygen_per_unit_mass_in_sea_water) should not be used without adjustment.

  • DOXY_QC is systematically set to 3: bad data that are potentially correctable

Coriolis DAC implemented that decision on July 1st 2020 and gradually resubmitted existing files.
Now, we put our effort in delivering DOXY_ADJUSTED with PARAMETER_DATA_MODE=A, more suitable for scientific use.

To deliver a real time DOXY_ADJUSTED parameter, a float PI should provide its DAC with an adjustment. The adjustment may be a gain, calculated from the 5 initial floats cycles with:

  • Comparison with in air measurement (ppox)
  • Comparison with bottle samples
  • Comparison with a climatology

 Sorry for the inconvenience it may cause during the transition phase.
