Fuel cell impacted available instrument power, so telemetered data are not available or reliable. Recovered data are available for instruments that could record internally.

No telemetered data are expected because of ground faults on the seafloor Multi-Function Node. Recovered data are available from instruments recording internally.

CP04OSSM D00009 buoy broke free and went adrift on 1/30/2019, 1500UTC. All instruments on the MFN ceased telemetry on 1/30/2019 and instruments on the buoy/NSIF continued to sample through 2/1/2019. No more telemetered data expected for this deployment.

Deployment 10: Telemetered data from all MFN instruments could be delayed up to 3 days due to a limitation in communications with the MFN.

Deployment 11: MFN offline due to high voltage short on 2019-11-15. No telemetered data expected from instruments on the MFN; instruments with external batteries will continue to log internally.

Deployment: 1

There are only a few data points available for this deployment. Data should be annotated to explain what the issue was.

Deployment: 2

recovered_host data aren't available for this deployment. According to the ingest csv, the raw data files are available, although the files aren't specified in the file path. Data should be ingested or annotated to indicate why they aren't available. There are only 3 days of telemetered data available.

The dissolved oxygen data products that are corrected for temperature (DO - Pressure Temp Sal Corrected and DO - Temp Corrected) are anomalously low (<50) compared to values from other deployments. Saturation and DO data not corrected for temperature are within the same ranges as data from other deployments, suggesting something is wrong with the temperature correction for his deployment.
