There are no recovered_host data available for download for this deployment. According to the ingest csv, the recovered_host raw data files are available. These files should be ingested or the datasets should be annotated to explain why the recovered_host data aren't available.

A vendor error in assembly pinched closed an internal tube carrying the surface air stream into the sample volume, resulting in an erroneous measurement. Users should not use the PCO2A air measurement for the Spring 2015 deployment (deployment 01), nor the associated sea-air pCO2 flux estimate.

UPDATED, 2020-01-28: The QC flag for the air measurement has been reset to fail. Users should not use the PCO2A air measurement for the Spring 2018 deployment (deployment 0), nor the associated sea-air pCO2 flux estimate. *PCO2A air measurement for the Spring 2018 deployment is considered suspect. Recent investigations have indicated a vendor error in assembly may have pinched closed an internal tube carrying the surface air stream into the sample volume resulting in an erroneous measurement.

Due to a firmware bug, the sensor zeroing function for correcting the baseline drift over time is not currently saving the updated reference value used to compute 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.
