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.

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: Delivery of telemetered data from instruments on DCL26 could potentially be delayed up to 24 hours.

recovered_inst data aren't available for download for deployments 1, 3, 4, and 5. According to the ingest csvs, recovered_inst data aren't expected for deployments 1 and 4 (these dataset should be annotated). recovered_inst raw data files are available for deployments 3 and 5. These data should be ingested or the datasets should be annotated.

Suspect upward_velocity values for deployments 2 (middle panel in attached plot) - values periodically exceed northward and eastward values.

CP04OSSM-RID26-04-VELPTA000
Deployment: 3

There are 13 days in deployment 3 where telemetered and recovered_host data are available for a time range where recovered_host data aren't available. This should be investigated.

The sampling rate for deployment 3 is 1 Hz, where for every other deployment there is 1 sample taken every 15 minutes. This should be annotated to explain why the sampling rates are so different.
