No recovered data available because the Instrument was lost.

Deployment 8: Instrument was disabled 2018-06-18 through 2018-09-10 due to power generation issues on the buoy. No telemetered or recovered data expected for this time period.

Method: telemetered
6/18/18, 1:56 AM 10/26/18, 3:52 PM

Data telemetry disabled due to chronic issues with power generation and management. The instruments could be revived to send data via telemetry when sufficient power is available. Note: Instruments may continue to collect data on internal battery power.

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 11: *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 2019-11-04. No data expected after this point.

Deployment 11: UPDATED 2020-04-27: As of 2020-03-12 telemetered data for most instruments are being sent home via Iridium. A gap in telemetered data is expected between 2020-01-08 and 2020-03-12 and will not be backfilled but these data will be available upon recovery.* As of 2020-01-08 both fleet broadband telemetry pathways have failed and data can no longer be telemetered to shore from this mooring. Instruments will continue to log data which will be available upon recovery.

Deployment 11: The PCO2A instrument failed (possibly a membrane or lamp failure). The instrument was powered down for the rest of the deployment on 4/9/2020.

pco2_co2flux is an array of fill values for every deployment. See CP01CNSM-SBD12-04-PCO2AA000 for additional notes on potentially the same issue.

Deployment: 1

There are no data available for download for deployment 1. According to annotation ID 439, recovered data aren't available because the instrument was lost. However, according to the ingest csv, raw telemetered data files are available. These files should be ingested or the annotation should be updated to indicate that no data are available for this deployment.

pCO2 Atmosphere (uatm) values at the beginning of this deployment are substantially higher than the values at the end of deployment 4.
