CP01CNSM-SBD12-04-PCO2AA000	11/21/13, 1:15 PM	4/17/14, 8:00 PM	Data not recoverable. Id: 494 By: leila
CP01CNSM	2/16/14, 7:00 PM	4/17/14, 8:00 PM	Surface buoy exploded due to hydrogen build-up in well. Id: 103 By: swhite Flag: not_operational Exclude: No
CP01CNSM	12/13/14, 1:47 PM	12/15/14, 3:58 PM	Deployment 2: Short deployment due to the fuel cell not functioning correctly. No data expected. Id: 709 By: cdobson
CP01CNSM-SBD12-04-PCO2AA000	10/13/16, 2:36 PM	6/9/17, 12:05 PM	Instrument failure (remote troubleshooting doesn't seem possible). Id: 599 By: leila
CP01CNSM-SBD12	4/23/18, 1:22 PM	10/29/18, 9:48 PM	Deployent 9: Power down - Instrument Disabled. No telemetered or recovered data expected for this time period. Id: 1378 By: leila Flag: not_operational Exclude: No
CP01CNSM-SBD12-04-PCO2AA000	4/6/19, 10:35 AM	9/26/19, 1:15 PM	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 Id: 1714 By: swhite Flag: fail Exclude: Yes
CP01CNSM-SBD12-04-PCO2AA000	10/27/19, 8:00 PM	11/14/19, 7:00 AM	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. Id: 1811 By: cdobson
CP01CNSM-SBD12-04-PCO2AA000	12/7/19, 5:30 PM		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. Id: 1906 By: cdobson Flag: suspect Exclude: No

CP01CNSM-SBD12-04-PCO2AA000 Deployment: 1	11/21/13, 6:15 PM	4/18/14, 12:00 AM	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). By Lori Garzio, on 7/31/19
CP01CNSM Deployment: 2			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. By Lori Garzio, on 3/22/19
CP01CNSM-SBD12-04-PCO2AA000 Deployment: 3	5/10/15, 12:00 AM	10/23/15, 7:40 PM	Instrument appears to have failed shortly after deployment. This should be annotated. By Lori Garzio, on 7/31/19
CP01CNSM-SBD12-04-PCO2AA000 Deployment: 5	5/13/16, 1:50 PM	10/13/16, 7:34 PM	Suspect data - measured_air_co2 values at the end of this deployment are substantially lower than those at the beginning of deployment 6. By Lori Garzio, on 7/31/19
