recovered_inst data are not available for download from deployments 3 - 5: the raw data files are available according to the ingest csv. The data should be ingested or annotated to indicate why they are not available.

Suspect upward_velocity values for deployments 4 - 6: values exceed northward and eastward values. 31%, 86%, and 15% of the values for upward_velocity are outside of global ranges for deployments 4, 5, and 6, respectively.

The sampling rate for deployment 3 is 1 Hz, where for every other deployment there is 1 sample taken every 30 or 60 minutes. This should be annotated to explain why the sampling rates are so different. 52% of the upward_velocity values for this deployment are outside of global ranges.

According to the manufacturer, data are suspect when the instrument is tilted more than 20 degrees (measured by pitch and roll).

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

Deployment 3: The VELPT instrument deployed was a Series A which has a 300 m rated head rather than a Series B which has a 3000 m rated head. The VELPT was deployed outside of operational range; treat data as suspect.

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 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.
