Due to a firmware bug, the sensor zeroing function for correcting the baseline drift over time is not currently saving the new reference value to compare the raw CO2 value outputs during the measurements. The sensors are zeroing at the end of the sample cycle when scheduled, but the firmware is not storing the new value. This results in the original zero reference value being used for all measurements and an observable and consistent negative drift in both the air and water CO2 values. The vendor has indicated that the data may be correctable post-recovery, however at this time no such correction algorithm has been provided

Deployment 12: *UPDATED 2019-11-14: Instrument is powered back on and functional as of 2019-11-14. A data gap is expected 2019-11-04 through 2019-11-14.* PCO2A2 was disabled 2019-11-04 after issues were observed starting 2019-10-28. No data expected after this point.

Deployment 12: Due to a hardware issue, PCO2A zeroing incorrectly as of the start date/time of this annotation. Resulting PCO2 values are incorrect and will need to be post-processed.

pco2_co2flux is an array of fill values for every deployment. According to one provenance.json file, there is an error in the pco2_co2flux function in ion_functions.data.co2_functions: "unsupported operand type(s) for NoneType and NoneType and message: "Unable to insert parameter: Parameter(2805: pco2_co2flux).

measured_air_co2 decreases throughout the deployment. A similar decrease isn't observed in data for the same season in subsequent years (Jan-Apr 2016 and 2017).

Annotation ID 709 "Short deployment due to the fuel cell not functioning correctly" should be updated to indicate that this refers to deployment 2, and data aren't expected from most instruments for this time period.

Suspect data - measured_air_co2 values at the end of this deployment are substantially lower than those at the beginning of deployment 6.
