Stopped receiving any data from the NUTNR on 2016/07/14 06:00:02.808. No apparent reason.

The Satlantic ISUS instrument has been discontinued, and all OOI ISUS units have been converted to the Sea-Bird SUNA model. A new data parser is in development, and any resulting data gaps will be filled once the parser has been delivered and the data are processed.

Method: telemetered

We are experiencing an intermittent failure of communication between the systems on the NSIF and the buoy. While the systems on the NSIF are operating, due to a change in the telemetry system, only a finite backlog of data is telemetered to shore. As a result, when communications are restored, some of the data backlog may be missing and there may be gaps in the record.

Due to a bug in the mooring telemetry system, data during this time range was not telemetered to shore. It was recorded on the mooring and instruments and will be available in the recovered data streams.

Annotation ID 1413 should be updated when the parser is complete and the data from the new instruments is ingested.

There is no pressure variable in the .nc files. This should be a coordinate.

Data generally look suspect for all deployments of this instrument (the ISUS model) because of the prevalence of negative values. The dataset should be annotated if there is a known issue with this instrument to inform users if all or some data should be considered suspect.

Deployment: 6

No data available for this deployment - the ingest csv indicates that the data weren't ingested because a new parser needs to be developed, but this dataset should still be the old ISUS data and can be ingested with the original parsers.
